SRNE 20KW parallel ASP journey.

Buying a diy box also?
No. There's room on my shelf / rack for 2 more packs, I designed it to hold 6 when I built it.
Someday I'll build out a cabinet like Zwy.
 
Said shelf here.

I'm thinking I'll run this pack 16S2P. I might even reconfigure the EVE cells the same way. It's extremely rare I run over 60A through each of the 4 current packs, C rates are low. Keeping 4 packs will also help keep BMS SOC somewhat accurate, even though I don't use comms. 6 would be miserable, 4 already irritates me enough...

Yup, it's that time of year for me, too.
But the LF280K's that I usually get, are sold out.
I Guess I'm going to have to try out either the LF304's , or the MB31's.
I have about a month to decide.
 
Maybe zwy can kit out that style of cabinets with everything installed except the cells, for the diy market after he retires from his main job. Shipping won't be pretty.
I'm still working over 60 hours per week even in semi retirement. Come another 2 weeks, I'll have the occasional 100 hour week during heat waves.

Building the boxes could be done easily. But for the price of used ones out there, why bother?

Get the box similar to the one in the shop. 20" deep. It will make it much easier, even if you only put in 4 packs the full length. If you can find one, find the 72" W x 20" D. That would be perfect for 8 packs with more room in the center. The 62" works but the RH door will have to be be unbolted if you want to get in deep for maintenance.
 
I give up fighting the sun for the day.
New record achieved.
Need to get those last panels on the 4th MPPT if I want to break 100 in a day.

Oh now FedEx is supposed to deliver tomorrow, delayed a day.... This time of year I'm in no hurry for more cells (now there will be a week of clouds).
 
Operation 3 phase is not working good. I have 3 inverters in 3 phase, setting 31 is 3p1, 3p2, 3p3, setting 38 is 120v, and setting 68 is 0, Voltages from inverters to neutral stay rock steady at 120v, but phase to phase if a 20 to 30amp load in single phase, say a to b phase, that voltage will drop as low as 190v, and goes lower as you add load. Not sure what is going on here. I would have all six inverters hooked up but I am waiting on a db15 cable to get here before I can do that.

120v to neutral, while 190v between legs?
 
20 amps of load added to a to contact phase. Look how voltages go up and down. Every thing was 208v with minimal house load. 1st meter is voltage a to b, a amperage. 2nd meter is b to c voltage, b amperage. 3rd meter is voltage a to c, c amperage.
