API LI 252 is ready for use. Totally assembled, prewired, tested and programmed. Includes 16, 252 AH cells, heavy duty steel enclosure, multi function BMS system with remote monitor, 50 amp solid state
Lipo4 battery charger.
These systems can be used with any 48 vdc inverter. CAUTION: Do not use inverter/charger, charging system. Only use our system charger for battery charging. Use the inverter only for power production. Using an inverter/charger for charging could do serious damage to this battery bank. Battery charging MUST be controlled by

the BMS. This also gives you the best, cleanest power possible, because you can charge our API LI 252 while using the power.
We also have available 40 amp 200vdc & 20 amp 600 vdc solid state relays (mounted on heavy duty heat sinks) for controlling other charging sources such as PV. These solid state relays are controlled by the BMS system. The 200 vdc relays control any 150 vdc MPPT charge controllers and the 600 vdc control any 600 vdc MPPT charge controllers. Now you can easily switch your grid tie system to a primary power system and turn the utility company off!
40 amp, 200 vdc $200.00 20 amp, 600 vdc $217.00
TECHNICAL SPECIFCATIONS:
58.4 vdc max charge voltage, 46.4 vdc low voltage display lights up, 41.6 vdc automatic low voltage battery disconnect, 44.8 vdc auto reconnect. We choose to use 16 cells for a nominal
51.2 vdc because it allows the most efficient use of power. 15 cells give you 48 vdc nominal but the voltage will drop to inverter shut down prior to max power usage. Our cells are individually monitored with our Battery Management system (BMS). Our systems can be charged and discharged at the same time. This results in the best, cleanest power possible .
