How to use

Install the controller following the manufacturer’s mounting and wiring guidelines, ensuring correct orientation and adequate ventilation. Connect the PV array to the PV input terminals and the battery to the battery output terminals, observing correct polarity. Configure the charge profile to match the battery chemistry and capacity using the controller interface or compatible external setup tools. Verify system voltages and operation after initial commissioning and periodically check connections and settings during normal operation.

Recommendations

For optimal performance, design PV array voltage to remain within the controller’s input range under all expected temperatures, and use appropriate fusing or circuit protection on PV and battery circuits. Regularly monitor battery state and adjust charge settings for battery type and age to maintain capacity and extend service life.
