datasheet for panel in question https://www.renogy.com/content/RNG-160D-SS/160D-SS-Datasheet.pdf datasheet for mppt 100/30 in question https://www.victronenergy.com/upload/documents/Datasheet-SmartSolar-charge-controller-MPPT-100-30-&-100-50-EN.pdf panel datasheet says shortcircuit current is...

thanks for the input. after lots and lots of research i went ahead and ordered the victron smart mppt 100/30, and the victron ip67, but the smart orion-tr 12/12-25 is pretty much out of stock everywhere. rumor has it they pulled them all back in to fix a defect and it may be next month before...

I have dual 220amp alternators spring not overly concerned but definitely see the value in regulating it. Especially to avoid fire. what side of the cable does the Orion go on? Starter battery side in truck? Or LFP side in trailer?

My alternators would almost fill up my previous 300ah silver calcium batteries. They worked well and pretty fast. But I think those batteries were damaged and would never hold rated capacity. They’d drop fast too even after being connected to the wall for days. so if i'm going to replicate...

So everything discussed so far lives in a trailer. My truck has a National Luna smart solenoid isolator which I connect directly to the batteries via a long cable so I can charge while driving. I would have plugged that into the manager30 but now I’ll just connect it right to the battery...

Thanks. That makes sense. I think I will get more solar but I suspect I’ll wind up with two panels and a blanket or something and maybe that means I’d be better off with two mppt? Which would let them run more efficiently? So when I get the extra solar I can add a controller... so I’m adding...

is there a disadvantage the other way? like if i got a 30A and only hook up a 120w panel? 120w/13v=9.2a max so am i wasting something or being less efficient?

Which voltage do I use? The colts coming out of the panel or the battery? It would be 13v from the battery but I’ve measured the panel close to 20v on a really sunny day

do you guys have a preferred victron vendor? on the solar controller... Victron SmartSolar MPPT 100 20A 30A & 50A Solar Charge Controllers how do i know if i want 20, 30 or 50A?

When I removed the three batteries and put a multimeter on them they said 12.77v 12.77v 12.78v Respectively. I need to read up on properly testing batteries again. But they all say fully charged and had been connected to shore power and that charger for a week.

That’s the charger I’m removing that came with my trailer. It’s been charging 3x 102Ah silver calcium batteries. From that spec sheet it says recommended up to 240Ah so I’m wondering if that might be a factor in the poor performance

https://www.meanwell.com/Upload/PDF/PB-360/PB-360-SPEC.PDF What do you think about this charger?

you're saying if you don't fully charge it, it lasts longer?

does it matter if we're talking lifepo4 instead of lead?

that's exactly the sort of thing i was concerned about. so, why is it just solar? could it happen to 1 solar and 1 DC charger?

Thanks! what solar charger would you suggest?

thanks, that's what i was getting at on the voltage. however, I was trying to figure out how having disparate chargers would work. how do they keep from interfering with each other, if for example, one is a vehicle alternator and the other is a solar panel i meant the voltage from the...

So you’re saying even if the voltage from the battery is a bit low, the dcdc can raise it to put the right input into the battery? and if there are two in parallel both trying to charge the battery, they both will put the precise charge profile without doubling it? I’m still mystified how this...

i'm not arguing. just asking questions to get educated. granted, their brochure is light on details, but reading their manual, it does include some things like on your list like remote battery monitor, which includes temperature. and i think it has the ability to calculate how long it takes...

i get the SPOF argument, but I don't understand your less capability statement. it seems like you'd have more possible features, not less. if you're saying you would connect both the vehicle alternator and solar both to the batteries in parallel, so they are both charging it, how is that...
