Hi I am fairly new to the forum but have been interested and dealing with solar for a few year, so please bare with me. I currently have a 3.1 kw solar array with a midnightclassic 150 charger and a magnum ms4448pae with Magnum mmp175-30d mini panel. This currently runs a small house with a well pump. I will attach pdf files corresponding to those items. I am phazing out of my old 8 lead acid crown 430ah battery bank and looking to go with a simple diy 48v system. My system build should be straight forward and probably will be to most of you but the only factor is my 230v 30 amp 1.5 hp franklin submersible well pump. My lead acids never had a problem running them but recently I purchased a meritsun 10kwh hour bank from alibaba but for the luck of me I have not been able to get it to run the well pump...everything else no problem. Link to that thread I posted earlier regarding troubleshooting.https://diysolarforum.com/threads/new-48v-200ah-10kwh-battery-troubleshooting.13094/
Ling story short i will be selling it. That being send at max draw the well pump before it flips its own breaker would draw 30 amps at 230v which I calculated to be just around 160 DC amps for the inverter to need to produce this (considering the startup amps of the well pump). Other than that my loads are basic and my 4400 watt inverter does great. I would like to make this beafy with larger bus bars or doubled up factory ones so that i can pull plus 160amps continuous without harming them.. My system was easily able to recharge the meritsun 200ah 10kw powerwall so I was leaning towards 280ah cells but may have heard that wasn't the best. Need advice on full battery bank build including cells with alibaba links if possible, bms or multiple bms if two strings in parallel, bus bars, case for system if you have creative ideas if not I can manage ?, and anything other that is nessary to have a simple, safe Reliable system. In advance thank you all.
