Solar System Monthly Validation Report – October 2025

This report presents the system validation and verification results for my solar power system and battery bank after 61 days of off-grid travel. The sole power source consisted of two 250-watt solar panels (Rich Solar) connected to a solar charge controller (SmartSolar MPPT 100/30) and a 200 Ah battery bank (two LiTime 12V 100Ah Group 24 Deep Cycle LiFePO4 batteries). Neither the AC-DC charger (Blue Smart IP22 Charger 12V-30A) nor the DC-DC charger (Orion XS 12/12-50A) was used during this period. The objective was to evaluate the adequacy of the solar system and battery bank capacity to support off-grid travel demands.

System validation and verification for a vehicle’s solar-based electrical system involves confirming that the setup meets design specifications and performs reliably under anticipated operating conditions. Validation ensures the system addresses the intended purpose (e.g., providing consistent power for off-grid requirements), while verification confirms proper integration and functionality of components. This process is critical for my setup, where approximately 65% of operation occurs under forest canopy (reducing solar input) and 35% in semi-open areas with partial sunlight, enabling early identification of inefficiencies.

The histogram below illustrates the maximum state-of-charge (SOC) achieved by the battery bank during each 24-hour cycle. Over the most recent 31-day period, the maximum SOC ranged from 69% to 100%, with 24 days recording values between 96% and 100%. Although I did not log the specific times when SOC reached 100%, this value was frequently attained around midday. These results indicate that the system has sufficient solar capacity for most of October’s operating conditions. It will be valuable to assess performance during December and January, when solar input is typically lower. Overall, I am satisfied with these findings, as the system exceeded the design goal of providing sufficient power for seven days using solar energy alone, successfully delivering power for the entire 61-day period.
RC 25-485.jpg
The histogram below illustrates the minimum SOC achieved by the battery bank during each 24-hour cycle. Over the most recent 31-day period, the minimum SOC ranged from 50% to 93%, with 22 days recording values between 79% and 89%. The minimum SOC was typically reached early in the morning, just before sunrise. During the system design, my goal was to ensure the SOC rarely dropped to 25%. The fact that the lowest recorded SOC over the 31-day period was 50%, with all other values higher, demonstrates the system’s robust performance.
RC 25-486.jpg
The screenshot below, captured from the Victron Energy solar charge controller, displays the energy collected by the system over the past 31 days. The white portion of each column represents the percentage of time spent in Bulk charge mode, while light blue indicates the Absorption phase and medium blue denotes the Float phase. The data shows that the system reached the Float phase on well over half of the days. This indicates that the system was fully or nearly fully charged for approximately two-thirds of the time. On October 20–22 and 30-31, rainy conditions limited solar input, while on October 23-24 the system quickly recovered pulling in as much as 1.08kWh on a single day.
RC 25-487.jpg

This data is associated with the chart above. I attempted to attach the CSV file to this post for further review but the uploaded file does not have an allowed extension.
RC 25-488.jpg
I will periodically measure system performance and publish updates similar to this report. Evaluating the system’s behavior over the coming years will provide valuable insights into its long-term performance and alignment with design expectations.

@Pacific Northwest yetti - I’m in the same position and glad I invested the time and budget into a fully customized Victron Energy power architecture for my overland rig. Years back, I seriously evaluated REDARC, whose rugged engineering is purpose-built for adventure platforms, but after direct consultations with both teams and hands-on evaluation of their product lines at Overland Expo, here’s my breakdown:

Both Victron Energy and Redarc excel in vehicle power systems for off-grid operation, yet they embody distinct engineering philosophies. Victron prioritizes modular, scalable architecture with deep ecosystem integration - enabling precise customization, multi-device synchronization via apps, and seamless expansion for complex, high-capacity builds across global markets. In contrast, REDARC engineers rugged, all-in-one solutions optimized for space-constrained, high-abuse environments, delivering integrated charging (DC-DC, solar, AC) in compact, vibration-resistant packages that minimize component count and installation complexity. Users value Victron’s advanced telemetry and upgrade flexibility for evolving systems, while REDARC's proven resilience in extreme conditions, such as deep-water fording and prolonged heat, makes it ideal for minimalist, mission-critical rigs. Both are premium-tier, but Victron’s distributed modularity often scales cost with system size, whereas REDARC’s bundled platforms optimize value through integration. Victron leads in global availability; REDARC maintains dominance in Australasia.

Here are a few screenshots from the Victron Energy application that often review - I'm a numbers guy so I love the level of detail provided:

Unfortunately, for several reasons, it looks like I will be the only person to complete the entire NEBDR, and the details that surround the group breaking apart don't really matter at this point. I'll simply state that a member of the group with presumably good intentions began to invite several other vehicles to join an in-progress adventure and I was the first to peer into the future and call it for what it was - a failed plan. If we meet on the trail someday and are sitting around a fire sharing stories, I'd be happy to walk you through step-by-step and identify where things began to fall apart, and more importantly, why.
RC 25-469.jpg

So here I was, alone with 350 miles to complete, and time was no longer a consideration. I decided to slow the pace down significantly, stop more, walk around the area or hike a short trail, listen to the river and the trees, feel the cool crisp autumn air sting my face, and watch a fallen leaf carried away by the swift current. This is what I came for.
RC 25-470.jpg

Since I frequently travel alone in areas without cellular service I carry an assortment of recovery options. I carry four Maxtrax MKII traction boards. Maxtrax are lightweight, durable traction boards (also known as recovery boards) invented in Australia in 2005, made from UV-stabilized, engineering-grade reinforced nylon. Primarily designed for off-road vehicle recovery, they feature aggressive cleats for grip, ramped ends for easy tire access, built-in handles, and shovel-like undersides. They're compact (13 inches wide and 45 inches long), stackable, and weigh around 5-6 lbs each. While their core purpose is vehicle extraction, Maxtrax are versatile tools for off-roaders, campers, and adventurers. Here are some of their uses: (1) Vehicle Recovery - Place under spinning tires to provide instant traction and allow the vehicle to "climb" out by idling forward. (2) Terrain Bridging and Obstacle Navigation - Stack or link boards to create temporary ramps, bridges, or steps over gaps, ledges, or uneven ground. (3) Camping and Leveling - Use flat or stacked to create stable platforms for uneven parking.

The Rocky Gorge thundered below as she stepped into the frame, its white water swallowing every sound. Sixty feet away across the churning mist, she looked straight at me and asked without a word: May I be in it?

I nodded, lifted my hand in a clear thumbs-up, and watched her shoulders ease with understanding. Then I opened my palm, fingers pressed together, holding it steady in the air like a silent command - stay perfectly still - and she did, her soft body poised on the jagged rocks as the shutter stretched seconds into silk. When the final frame clicked shut, I gave her another thumbs-up, and she answered with a heart-stopping smile before I slipped away down the trail, leaving behind only the echo of our wordless collaboration and a photograph that holds the moment we both decided to make something beautiful together.
RC 25-472.jpg

Near the end of section six of the NEBDR, I tackled the forbidding ascent of Mount Washington State Park in my sturdy 4.5-ton adventure vehicle. At the base around 1,500 feet, conditions felt deceptively warm and serene, with balmy breezes and golden leaves setting a welcoming tone for the journey ahead. My 6.4L HEMI engine delivered a deep, resonant rumble, steadily powering me through the eight-mile unrelenting climb to 6,288 feet, where each twist and turn built a rush of adrenaline - equal parts fear and excitement. As I gained elevation, the scenery unfolded in surreal splendor: distant mountains veiled in hazy blue, with wispy clouds drifting by and the sky taking on a vast, otherworldly quality, as if I'd entered a different realm. Then, transitioning into the stark alpine zone above about 4,500 feet, where trees thinned into resilient shrubs amid exposed granite, the captured photo gazes up the winding road toward a sharp curve flanked by a sheer rocky cliff that plunges into seeming oblivion, heightening the sense of perilous adventure. Yet, upon reaching the summit, the calm below surrendered to biting cold and relentless gale-force winds, a raw reminder to bundle up against the mountain's unpredictable fury.
RC 25-473.jpg

Mount Washington, the highest peak in the Northeastern United States at 6,288 feet, has a rich history dating back to its first recorded European ascent in 1642. Named after George Washington in the late 18th century, it became a tourist destination in the 19th century with the establishment of the Crawford Path in 1819 (the oldest continuously maintained hiking trail in the U.S.) and the Mount Washington Auto Road in 1861. Scientifically, the mountain is renowned for its extreme weather due to converging storm tracks, featuring an alpine tundra climate with a treeline around 4,400 feet and average snowfall of 280 inches; it also hosts the Mount Washington Observatory since 1932 for subarctic research. It holds notable records, including the Northern and Western Hemisphere's highest measured surface wind speed of 231 mph in 1934, hurricane-force gusts on over 100 days per year, a record low temperature of -50°F in 1885, and a wind chill of -108°F in 2023. Visitors should heed stark warnings about the mountain's dangers, as more than 161 fatalities have occurred since records began in 1849, with falls being the most common cause, often exacerbated by rapidly changing conditions, poor preparation, and hypothermia.
RC 25-474.jpg

At 6,288 feet atop Mount Washington, my photo of my AEV Prospector and Four Wheel Camper stands out sharply against the stark backdrop, the lighting dramatically different due to the thinner atmosphere, about 20% less dense than at sea level, which reduces haze and scattering, resulting in deeper blues, crisper shadows, heightened contrast, and more saturated colors. With less dust, moisture, and pollutants in the air, the light feels cleaner and more intense, giving the scene a vivid, almost surreal clarity that makes the image appear strikingly luminous and hyper-real compared to shots taken at lower elevations.
RC 25-475.jpg

As I drove north and finished section six, I rolled into Gorham, NH. First, I located a Ram dealer for an oil change, then a side-by-side (SxS) rental shop that also offered showers for $0.25 per minute. It had been weeks since I'd enjoyed a long, warm shower, so I took full advantage. Finding showers on the road can be challenging in remote areas, where your main options are campgrounds or truck stops (if you're near an interstate). In towns, check YMCAs, gyms, or other unexpected spots - I've showered at a hair salon in Arizona, a public pool in Texas, and now an SxS rental shop in New Hampshire.
RC 25-476.jpg

Section seven of the NEBDR is 176-miles long and becomes more rugged and remote as I press on towards the Canadian border, opportunities for food and fuel are becoming even more sparse now. It begins in Gorham, New Hampshire, heads east through a notch in the mountains crossing into Maine, turns south and east for a bit, and then shoots north ending in Rangeley, Maine.
RC 25-477.jpg

Rangeley, Maine - I had been there decades ago for military training. It was in February, and the snow in the mountains was so deep we had to wear snowshoes. The average daytime temperature was in the single digits, and every night was below zero, with one night recorded as the nation's low at -30°F. This is the first time I had thought about that location in a long time, and as I drove closer, I could feel those deeply rooted, fear-based memories slowly surfacing.

At first, I tried to distract myself with tasks, such as listening to a podcast or checking my navigation. But as darkness fell and the distance between me and that place closed, the gates in my mind opened, and a flood of memories and emotions overwhelmed me. Time spent in the Resistance Training Laboratory produced some of the highest recorded levels of cortisol ever documented in humans. We spent nearly a week in that phase alone. I’m talking about levels higher than someone undergoing major surgery or a skydiver making their first jump, but even worse. We were starved, exposed to sleep deprivation, forced into stress positions, endured torture in the form of soft-cell and hard-cell interrogations, sensory deprivation, sexual humiliation, mock executions, etc. The Officer In Charge of the school had been a POW in Vietnam for seven years and was permanently disfigured.

Some students experienced mild environmental injuries, such as frostbite, while others suffered physical injuries like sprains or broken bones. One student, years before I attended, even broke his back; a close friend, Larry had his jaw broken and was removed from training. Over the years, there were a few deaths - heart attacks and even suffocation, we were young healthy men in our prime. Psychological injuries were also common, including dissociation, sensory distortions, and severe psychological stress. I suspect we all experienced different levels of these effects.

One thing is for certain: every man is a changed man after completing that training. There's no discharge in the war!

Surprised you were granted access to Mt. Washington in your rig. When I hit that area they said my setup was oversize, and to park and take the bus.

Basically we’re the same: full size Ram and a FWC Hawk?

You make a good point, @FAW3. I recall one of the team members mentioning, before we parted ways, that I likely would not be permitted to drive my truck to the summit. To confirm, I reviewed the vehicle restrictions on their website and found the following:
  • WEIGHT LIMITS - The weight limits below are referring to passenger and luggage weight, not the weight of your vehicle. These are approximate numbers used as guidelines.
    • Full size car or wagon: 1,000lbs
    • All minivans: 1,000lbs
    • 1/2 ton van, pickup or SUV: 1,200lbs
    • 3/4 or one-ton van or pickup: 1,800lbs
  • VEHICLE SIZE RESTRICTIONS
    • Maximum wheelbase on any vehicle: 176 inches
    • Maximum width on any vehicle: 93 inches including mirrors (mirrors may be folded in to achieve this width)
    • No pickups with permanent additions that extend wider than the cab (campers, rack bodies, or very wide mirrors)
Based on these criteria, my setup fell into a gray area at best - and likely did not comply at worst. I was prepared to discuss the matter politely, noting that while the weight limit for a one-ton truck was 1,800 lbs, my total load was 2,489 lbs (using only 55% of my available payload of 4,529 lbs), and the limits were described as “approximate numbers used as guidelines.” Regarding size, my camper did extend wider than the cab, yet its 80-inch width was well under the 93-inch maximum.

As @Pacific Northwest yetti suggested, I encountered a lenient gate guard on a warm, sunny day. After a brief inspection of my rig, he allowed me to proceed up the mountain. Before I drove off, he cautioned me about brake overheating and recommended descending in first gear using engine braking to minimize brake use. Out of respect, I followed his advice precisely. The ascent was slow and steady but uneventful. The descent, however, felt interminable; I pulled over multiple times at available turnouts to let faster vehicles pass. With the windows down, I repeatedly smelled overheated brakes from other vehicles - a clear reminder that the downhill journey was no trivial matter.

Should I return someday, I will most likely take the train. The climb was manageable, but the prolonged descent demanded constant attention to avoid over-revving the engine or overheating the brakes.

Bonus photo from atop Mount Washington: Here is how one of the small structures was engineered to withstand the extreme winds.

Great info @chet6.7 and I appreciate you sharing your first-hand knowledge with us.

I installed my 2 Low UnLoc from BD Diesel two years ago and enjoy using it more than I ever imagined. Here is an older link related to my installation. I used my Aux 6 switch in my cab to control mine since Aux 1-3 are for lights (bumper, ditch, and chase), Aux 4 is for my compressor, and Aux 5 for Victron Energy DC-DC 12V/50A.

Part Six of Six

Fall in New England doesn’t whisper; it roars in silence, every tree shouting for attention before the first hard frost strips them bare. My truck and camper slipped into a tunnel of molten gold - birch and maple blazing overhead, leaves drifting like slow embers onto the granite crystal metallic hood. I kept the windows cracked, let the chill nip my knuckles on the wheel, and eased along just fast enough to burn the color into memory before the forest turned the page.
RC 25-479.jpg

My peripheral vision caught it first: a sagging Ford Bronco II, plates yellowed and expired in ’99, parked nose-first against a cabin that had surrendered to moss and rot. I killed the engine and stepped out; the forest swallowed the echo. A few tires still held air but had sunk six inches into the duff, roots already threading through the wheel wells. I circled the house - shingles curled like old fingernails, windows punched out by weather or boredom. When was it built? 1940s? A summer place once, maybe - kids chasing fireflies, a wife humming over a cast-iron stove. Then the years: children gone, marriage cracked, or worse. Did he drive out here alone, park, and never leave?

How many more seasons before the roof caves, the walls fold, the forest reclaims the clearing? One day the property will grow over, and nothing will mark that a man once called this home, or ended here. The thought settled cold and clean: everything passes, but tonight the ruin still stood, and I was the only witness.
RC 25-480.jpg

This final alternate hard section of the NEBDR demanded commitment, and I tackled it solo. The ten-mile stretch split into two distinct halves: the first maintained, the second wild and unmaintained. Deep in the forest, I’d pause at every sign to read and absorb its message. This one looked official, yet it cited no state or federal statutes, so I pegged it as likely temporary - perhaps posted by a private crew working in the area. With no gates blocking the way, I pressed on cautiously: windows down to catch the thump of rotors, eyes sweeping the horizon across open fields. The section ended without incident.
RC 25-481.jpg

The Diode Dynamics LED lights now stabbed into the void, a cone of light swallowed by a wall of trees that pressed in from both sides. No moon, no glow, just the low growl of the HEMI engine and the faint crackel of tires on gravel when I paused to listen. A city street at night hums with life - porches lit, TVs flickering behind curtains, the soft pulse of humanity. Even country roads parcel the dark with mailboxes and distant barn lights every few miles, quiet promises that someone’s near. Here, the forest erases all of it: no silhouette of a house, no mailbox, no backup. One mistake and the night may own you - you must be prepared to get up, dust off, reload, recalibrate, reengage, and go out on the attack.
RC 25-482.jpg

With the NEBDR’s final few miles still looming, I turned off the main track onto a faint spur a local had sketched on a napkin back in town hours ago. My RAM 3500 growled over washboard until the trees broke open to a hidden lake pressed hard against the Canadian border. No sign, no number, just black water ringed by spruce and the faint glow of dusk. I eased onto the gravel shore, killed the engine, and let the silence flood in. This was my last night on the trail.
RC 25-483.jpg

Morning arrived in layers of mist. I stirred to birds trading calls across the water, watched the fog lift in slow curtains as the sun edged over the ridge. Steam rose from my cast iron skillet while the lake turned from pewter to gold. In that quiet, the truth settled: after all these miles, the trail would end today. If you chase the backroads alone, push past the last signpost and trust the silence, you’ll wake to moments like these - yours, free, waiting on any shore you dare to find.
RC 25-484.jpg

These final miles slipped by in silence - no radio chatter, just the steady thrum of the road below. The end of the trail was creeping closer than I cared to admit, so I eased off the gas and pulled over twice: once to fire up the diesel cooktop for bacon and eggs at noon, again at dusk to warm a pot of chili while the sky turned rust. No hurry, no blueprint for the day after hitting the border. I’d gone lone-wolf days ago, refusing to detour when the team bailed; they’d promised Starlink pings with lat-long texts so I could catch up. Nothing came - just empty signal and the long road ahead.

This trip’s quiet lesson: stretch a journey, savor the solitude, and trust our own compass when the rest go quiet. Push your rig to the edge, linger in the dust, and you’ll find the trail ends on your terms.
RC 25-485.jpg

I arrived at the Canadian border late at night, pulled up to the chained gate, and stepped out of my vehicle to see if anyone else was around. After traveling 1,556 miles through seven states - completing the NEBDR alone, two weeks after starting with others - here I was, shrouded in darkness with no one to share the moment.

I sat for a while, engine idling, lost in thought. My mind snapped back to my first helicopter deployment as an Aviation Rescue Swimmer. The radio crackled “Red Lion 615, A-7 in the water, fly heading…” - and I was already moving: five-point harness unbuckled, helmet off and heading aft before the words finished. In a blink I was rigged - summer wetsuit top, UDT shorts, harness, SV-2 vest, mask, fins, dive knife, radio, strobe - ready.

The airframe rattled like it might tear apart as the pilots shoved past the 120-knot NATOPS redline. Seconds later AW1 Nelson kicked a Mk 58 flare; its bloom marked the raft while the 243.0 MHz beacon screamed in their headsets. We overflew the target, banked hard, and I sat hanging out the cargo door. The helo bled speed, shuddering from forward flight into hover - then glass-smooth, it was time to go. Nelson slapped my chest, freed the gunner’s belt, and hammered three taps on my shoulder while screaming “Jump, jump, jump!” I dropped into the black, the fall stretching forever before the slap of water disoriented me - up, down, gone. Surfacing, the rotor wash hammered like a hurricane from the 10-ton beast forty feet above. I craned up, locked eyes with Nelson leaning out, signaled okay. The helo peeled away, leaving me alone.

Time froze as I floated amid the deep ocean swells. I cleared my US Divers mask, cinched the straps on my Rocket fins, flipped over, and peered into the endless black depths below. I prayed as I began to swim towards the raft - I had work to do, and I was here to make it happen. That night at the border echoed the same truth: as men, we're built to tackle virtually any task thrown our way, relying on nothing but our own grit and resolve.

Und die Vögel singen nicht mehr...
