I started building a system on Thanksgiving to test and adjust my parameters and hardware before building a Solar Power Plant Connex shipping container that will include 38 Kw of inverters, 30 Kw Solar panels @ 440 watt, and 240 Kwh LifePo4 of 280Ah cells in a 16s-1p config.
The test is with 13Kw of inverters, (2) 16s-1p 15kwh batteries, 5s-2p solar and my shop as a load. The solar panels are just sitting on wood frames on the ground for the test.
As a test some of the A/C wiring is exposed, but is only accessed by Me. The rest is 48 volt Dc with lots of Amps and is enclosed to eliminate shorts. everything exposed is on shunt trip breakers for quick disconnect if the system incurs a fault that could harm the batteries. Battery manual disconnect/breaker are 125 amp keeping battery draw to less than 1/2 C discharge-charge current and inverters are fused at recommended current.
All cells monitored by a Batrium Watchman Core and Cellmate_9 modules and min voltage per pack is 48.5 VDC to Max Voltage of 54.0 and cells are within 0.02 VDC Balance over entire range.
First solar power system attempt, But watched a LOT of Videos and Industrial electrical controls are my business of 40 plus years.
Torquing the battery Nuts to rated, Battery wires are super flexible home made connections with fuse holder for cell monitors. Shelves are rated to 1500 lbs per shelf and holds 800 lbs of batteries per unit.
Powering up the shop on "SOLAR" for the first time! I have lights!
Charged to Full on a bright Day in LA, That's Lower Alabama to Y'all from the West Coast. 14 amp float hitting the batteries. I need more Battery reserve when the heat is on, took batteries to 50 Vdc over night when in the 30's at night. So far So Good for testing, I have Will's favorite battery charger attached for just in case.
I received (32) 280Ah grade A Eve cells to build another 2 batteries packs last night.
