Our battery system is 54 V. The solar is three panels in series (two series for a total of six panels) which comes off the roof at 90 V.
We have four battery packs. Each battery pack consists of four 3.4 V LFP batteries in series or about 13.5 V total. The four batteries are in series for 54 V at float. The battery goes to 4 kW PSB inverter and 12 V converter.
Liberty coaches (the high end of Provost conversions at $1.8 M) have gone entirely to LFP and claim they have run through 2000 duty cycles with no discernible loss in ability.
I may be wrong but a 6V battery with 300 AH capacity is only equivalent to a 150 AH 12V batter (when put in series to get 12 V) or 75 AH at 24V (four 6 V batteries of 300 AH capacity).
Will admit that I am not happy without a real warranty
