I am in the process of creating a large bank of four TechDirect/BigBattery pre-built 24v BYD units (3kw usable capacity each). Three of the units are already "awakened" (three charge/discharge cycles) and connected in parallel. They are receiving their charge from (2) Schneider Conext MPPT...
Soon I'll be disconnecting my 740AH 24v L16 FLA bank and connecting 600AH of LFP (3 of the pre-assembled BYD units from TechDirect) to my Conext SW4024 inverter. I am concerned about tripping the BMS on the LFP batteries - and would like a good method of pre-charging the capacitors in the...
I recently purchased a Habitat automation device (control hub) to help me automate some diversion/dump loads (like an AC preheat water heater). I am AC and DC coupled and have a great deal of excess power which I am currently dumping (either by SCC reduction or by frequency shift shutdown of...
My system: Schneider Conext SW4024, 3kw DC coupled panels, 3kw Enphase AC coupled panels, 2 Conext MPPT 150/60 SCCs, Combox and SCP. Approx. 25kwh of batteries (20kwh of Gyll, EG4, Lifepower4 and 5kwh of refurbished BYD/TechDirect). Off-grid for 30+ years. Original SW4024 online since 2013...
I am in the midst of configuring a new lifepo4 battery bank in my off-grid home.
The battery bank will consist of three TechDirect pre-assembled BYD units with an installed BMS - approx 3kwh/105ah per unit. The BMS is rated at 130a continuous but I would derate that to 65 amps per unit based...
