Thank you for the detailed response. Much appreciated.

Thanks. I think my 800 watts going to the 200ah battery is plenty of power to recharge pretty quickly... especially when I'm using 90-100 Ah per day.

Thanks. Should have mentioned I do carry a 2000w gas portable generator as a back-up in case the sun disappears for a few days.

So I'm building an 800w solar panel system for my travel trailer. It already has an inverter (only 1000w so will probably upgrade to 2000w so the wife can run a few more things like her hair dryer, LOL". I have a 200ah LifePo4 battery. I'm reading about inverter/chargers combos. But if I am...

I have 4 200w solar panels that I want to wire in series-parallel on top of my travel trailer (currently only have 1 200w panel). I plan to use a 20a fuse for each string. I have a 12v 200ah LifePo4 battery, 60a MMPT solar charge controller and 1000w inverter. Question #1: how do I calculate the...

I will be running 90 to 100 ah per 24 hr period.

Yes. I will know that next week when I set everything up at home and test.

So my 2023 travel trailer came with a pretty useless 200w panel, 20 amp solar controller, 1000w inverter and (2) 100ah lead acid batteries. We like to boondock for 4+ days. Plan to run the following on 12v system: 3.1 cubic fridge, 10 in macbook laptop, LED overhead interior lights at night, and...

So was able to determine that the battery is in fact fully charged. I hooked everything back up to my RV and while the solar was charging, I connected the battery charger. It turned on, charged for about 30 seconds and then registered "full." Now the problem is, when I disconnect the solar...

Understood 3.25v per cell is norm. But when I'm measuring the battery using the posts on the outside, shouldn't that give me around 12v + or -? When I measure my flooded lead acid batteries, I'm getting 12ish volts.

Just curious if anyone else has encountered this issue with a new LiFePO4 battery seemingly dead and not charging. I went and got a multimeter and tested the battery and it's at 3.25V which seems crazy low. Almost wondering if that's "beyond repair damaged" low. Here's some backstory for...

So just replaced 2 100ah lead acid batteries with a LiFePO4 230ah battery with low temp protection. Also replaced the 30a PWM SCC with an MPPT 60A SCC because I plan to upgrade from 200w in solar panels to 800w next year. Here's the problem: shore power has been connected for 2 days and the...

Newbie question. Have a LiFePO4 230 ah battery for my travel trailer. I want to accurately know the life of the battery while camping and be able to charge it at home when storing in the off season. What equipment can you recommend? Do I just get a voltmeter to determine the present state of...

maybe 10 - 12 ft SCC to battery. Probably closer to 10

That's a great point. Right now, I'm only running 1 200w roof mounted panel and 1 200w solar suitcase (which runs on it's own SCC directly to the battery. So with 1 200w panel running through the existing wiring, there's no way I can max out the 30 amp. I guess I'll just need to worry about...
