    Search isnt working right now and ive a MPP LV2424 with the bulk charging at 29.2 and the float set at 27.2, am I leaving any capacity on the table at 27.2? As soon as I turn the batteries on the voltage drops to 26.8, etc etc

    Thank you for your response. The panels have a Voc of 24.3 I have a slight hodgepodge of batteries. I have a 100ah lifepo4 rich solar parallelled to a 260ah lifepo4 eco-worthy, and that same setup wired in series to get my 24v. The eco-worthy's were a gift so I decided this was the best way to...

    I have a 9.2kw battery bank and I am in the US. Will said that to size my array I need to divide the battery bank size by 5 for the hours of sunlight to get my batteries charged in a reasonable time. I currently have 800 watts of panels, 4x200w Rich Solar panels in series into an MPP LV2424(the...

    So, just to be clear you're saying I should go (Positive cablefrom inverter-->) 2-!00ah in parallel (0/0awg cable--->) 2-260ah in parallel (negative cable back to inverter)?

    I'll wire it up like this! because the way it is right now is... not that. this makes way more sense and will probably solve another issue I'm facing which I assume to be uneven discharging, the 2 batteries on the negative side of the 0/0 always hit their low cutoff before the others
