hey all, newbie here. i'm about in the middle of building my giant solar/battery setup.
its comprised of 2 systems: ~12kw panels+160kwh batteries for the house, and ~53kw panels+~500kwh batteries for my shop/barn.
last fall i got my small system panels installed on the barn, 30 440w sunpal power bifacial panels feeding into SEI 12k UP inverter. as you can see in the pictures, not ideal location, however i did cut down the trees throwing shade on these panels, but they are facing west, and eventually i think i'll relocate them to the big ground array that will be feeding the barn.


clearing out the area for the big ground array

as the snow started melting away, i began to install my battery banks.



temporarily testing battery/inverter comms

the battery packs are from work, they were used for development, and cant be sold, so i saved them from getting destroyed. the ones for the house i had to butcher up and rewire to work in 48v config, as the pack is set up for 360v nominal voltage. for the big shop system, i have a 50kw Deye 480v 3 phase inverter that does directly communicate with the pack bms.
so i just finally got some of the battery groups hooked up, still 3 groups to go, and then i'll also have a 2nd pack that will sit in this small shed that i'll need to hook up.
wiring all the 16s groups in parallel to the JK 300 amp bms, finally got it talking to the inverter and working through getting all the settings correct etc.
its been quite the challenge as i'm not very electrically inclined, lol. but the guys from work are helping me out with some pointers etc.
still trying to figure out this SEI inverter settings, seeing some different readings between the inverter and my main house meter, as well as it doesnt want to pull charge out of my battery up to the limit set in the BMS.
anyone out here using SEI/SRNE inverters thats well versed in their settings/config?
