I use the big NA map file, OSM is all that still works w/the latest Android, Google broke the antique street maps api that connects to the internet. I have Aprsdroid as a read only TNC off my Kenwood, it will receive and display messages but to send em I gotta use the kenwood or kajigger some...

I'm using a Kenwood D710G w/a Bluetooth serial module for APRSDroid OSM.

There are other panels than HIT, it 325W happened to be an ideal size for my roof.. do some research on high efficiency house panels, find the ones close to 20% or better and compare dimensions and layout.. less frames = more solar cells 100W panels are low voltage piddly antique tech, your...

You'd need 4 battleborn sized batteries in a 2s2p configuration for 200AH of 24V, that would dump about 86A @ 100% Solar input, which would be about ~0.4C, fastest you can charge em safely.. at that point id be building your own and saving money over a BB w/more flexibility and repairability...

You can install a simple disconnect relay like a battery protect and have it drop loads with some capacity in reserve, then wire up an override switch and you always have backup power.. thats what I do.. I drop my loads at 20% SOC on my LFP, and the LVD drops everything at 5% SOC.. so if I...

yeah if your like me with alot of solar and a little bank, it charges so damn quick that a full long summer day of sun results in most of the captured energy being disposed of, that could be done w/lesser solar much more efficiently. however my design philosophy was plan for the worst and hope...

The Panasonic HIT's have a higher efficiency rating, higher efficiency rating == more watts in less space, if your trying to cram the most solar wattage you can.. you will have more wattage on the roof with 20% efficient panels than you will with 16% efficent pannels.. if you buy house panels in...

Mindland needs to work on bringing handhelds w/repeater support, and licensed repeater base stations that don't cost $2k+ before we need to start communicating with non-existent infrastructure at the very limits of the license capabilities. We tried to see if the chicken or the egg would come...

If your on the same level plane the horizon will block all communications over 8 miles with a 10ft high antenna on both ends, dont matter if you have 2W or 200W your not penetrating the earth with UHF, surely I dont have to explain what the horizon is to a boat captain...

because you'll pay more money for it.. the license allows for it, so they built to it. My D710G has 3 power outputs, 5W/10W/50W.. I've talked to people in simplex ontop of Pikes Peak from Denver (~90m) with 10W.. almost never put my rig into high power mode, its pointless.. two way radio...

15W v 50W results in very little appreciable difference, 15W is more than adequate for most mobile applications.. without a mountain top repeater several thousand feet above average terrain there's little actual use for 50W of xmit power. On flat ground, if you have two 10ft high antennas...

Its a real damn shame Victron dont make this unit for North American Voltage Inputs/outputs, EasySolar 24/3000/70-50 MPPT150/70 24v, 2400W Inverter, 1680W Shore Charger, 2000W of Solar.. it'd be pretty much ideal and almost plug-n-play for OP, but its designed for EU AC IO.

+1 on house panels, check out Panasonic HIT's if your going to spend alot of time in hot areas, Ive been following your build and im sure your wanting to flat mount the panels w/no room for circulation under em, so getting panels w/great heat coefficient is going to reward you as the hotter...

Another option would be see if you can find a RV in a scrapper and snag its nice Onan genset.. that has all the push button start equipment and most of the work is done, my parents old RV has one onboard and it fires up and shuts down with a simple 12v switch, that would wire right up to...

generator battery should be charged by generator, no need to tie it into your DC system at all.. best your starting batteries just stay isolated if possible... Can you just push a button and it start up now? or do you have to pull the choke and push the button then put the choke back? If it...

I see, well then you need to look at Victron Venus and figure out how to wire it up to your GenSet (assuming its got electric start), I believe it has the capability of monitoring the house bank and if it gets discharged below an alarm threshold it will fire up the genset, recharge the batteries...

check out Victron's Orion DC Chargers, with a deep cycle your still in for a long drive to put a decent charge back into it.

yeah I'm not getting why the hell anyone would have a trailer hooked up to both power mains and a generator at the same time... either you have mains power and dont need a generator, or you dont have mains power and need a generator.. plugging em both in at same time w/an ATS just seems beyond...

it goes inbetween em.. close to the battery as its charging so it can boost any losses along the way.

blusea, I dunno nothing about AgCa chemistry but LFP will gladly take more current than is healthy for it, with a LFP bank and an alternator source you want a DC-DC just to regulate the max current.. they will suck up far more amps than is healthy for both the battery and the alternator.. most...
