Hi, I have a question for the group about my RV’s charge controller for the house batteries which I am switching to 12v 100ah lifepo4 using 2 in parallel. The present controller specs are as follows: WFCO 100AMP POWER CONVERTER MODEL:WF-68100A INPUT: 105-130VAC,15Amp, 1680W OUTPUT: 13.7VDC...

I’m seriously considering returning the BLUETTI suitcase, I just tried it out and it barely makes 200 watts in direct Arizona sun at noon. At the $700 plus price point I can do a whole lot better with the full size panels at $90 each and just the two in parallel right now are doing 320w with...

No, that manual is for the ac200p this is the ac200m so the values are slightly different at 10-145vdc solar input and 15a but still within range. Thank you for your assistance.

It’s 145v capable and 900w max in that input and your figures for vmp are correct. Thanks for the calculations .

Thanks for your assistance, could have made an expensive mistake.

Ok I was believing that it does have diodes, what about using 2 external charge controllers to facilitate this?

So are you saying that configuration can’t or shouldn’t be done? Is it because the 102 volts of the 250’s in series will back feed into the suitcase rather than combine with its 42v?

Can you give me a calculation that supports that? I’m thinking using the 250’s in series and running that in parallel with the suitcase.

I have a BLUETTI ac200w and I need a little help with my panel configuration. I’m looking to use the 350w BLUETTI suitcase panel 42v Voc 10a imp with 2- 250w 50.9v Voc 5.84a imp Sunpower panels, how should I configure the panels for max efficiency? Thank you for your help.
