    Upgrading existing solar in new RV

    Not really. Completely dependent on your situation since either setup can work great. 2 batteries in parallel is not a problem assuming they have a proper BMS. Note that even the SOK 200AH battery has a 100A discharge limit.

    Upgrading existing solar in new RV

    The SOK batteries have a 100A discharge limit. You will be very close to that limit if not over it with the 1200 watt microwave. If the limit was higher, I would have one of their batteries in my camper right now. Your plan would be fine is you had 2x SOKs in parallel.

    Ampere Time 200ah Lithium??? Any reviews?

    Just to clarify, the BMS built into the battery is fine and not tripping. What is tripping is the 2424lv controller/inverter when you load it enough to draw 35A from the batteries? Sounds like it could be going into low voltage cutoff. If that is the case, you either have an excessive amount of...

    Ampere Time 200ah Lithium??? Any reviews?

    Right. And the BMS should disconnect the load... temporarily. It did disconnect the load... permanently. He said that it "never recovered". That is the problem.

    RV Roof-mounted plus portable panels

    In parallel, the shaded panels wont pull the other panels down. Ideally, you would put a diode in series with each parallel run to ensure that one panel wont backfeed another but that really isnt necessary unless you have quite a few panels in parallel. Rather than deal with trying to match...

    Is Victron MPPT apps accurate?

    In order for anyone to help you debug this, it would really help for you to post even a hand drawn schematic that shows the location of the shunt(s). It seems like you might not have placed them where you want them or are interpreting the data incorrectly based in their position in the circuit...

    AWG solar panel size?

    You should be under 16 amps since you will be wired in series. 10AWG will work but less loss is always better and the cost difference is pretty small. Blue Sea has a great chart for figuring out wire sizing: http://assets.bluesea.com/files/resources/reference/20010.pdf

    CATL 271Ah cell issues.

    Last seen Yesterday at 9:46 AM I was planning to place an order through Michael. Not so sure now. I guess the outcome of this ordeal will guide my decision. So far, it isn't looking good.

    2S2P, mixing panel sizes

    Due to space limitations on my RV, I want to run: 2x Newpowa 180W panels connected in series 2x Newpowa 210W panels connected in series Both of those strings would be connected in parallel (so 2S2P) to a Victron 100/50 MPPT. I will be slightly over-paneled at peak output. I could just go...

    Planning UPS for chest freezer, need help with inverter choice

    FWIW, I have a small 110V AC refrigerator in my RV that draw around 60W while it is running. I have (had) a nice Samlex 600W (1000W peak) inverter that would occasionally trip on overcurrent when the fridge compressor turned on. Nothing else was on the circuit, the batteries were at >80% SOC...

    Alternator Charging of Lithium Iron phosphate on a travel trailer

    I have dual alternators/LA batteries on my 2020 F250. Would you mind elaborating on the "two distinct charge circuits"?

    New MultiPlus-II 12/3000/120-50 2x120V Inverter/Charger Install

    As was quoted from the manual, the issue is cooling. You could add fans to encourage airflow that convection would naturally create. Definitely a band-aid though.

    DIY bolted terminals on Overkill 120A BMS

    The connection at the lug is getting hot? That isn't a wire gauge issue, that is a connection issue. If crimped, ensure that the crimp is good. It is hard to get a good crimp with three wires into one terminal. You could also potentially solder the connection. Another option would be to take the...
