45A MPPT Solar Charge Controller - Charge Controllers for Solar Panels - 12/24//36/48-Volt
-
Detail
For 12V-48V battery systems: Connect the battery group first → Set the output voltage → Then connect the solar panels.
For 12V systems: Connect solar panels with ≥30V first → Set parameters → Then connect the battery.
The controller’s hardware over voltage protection limit is 180V. Ensure sufficient voltage margin during use. The recommended maximum open-circuit voltage for solar panels is below 150V to avoid controller damage.
For 12V batteries: Recommended solar panel input voltage is 36V-72V.
For 24V batteries: Recommended solar panel input voltage is 41V-125V.
For 48V batteries: Recommended solar panel input voltage is 80V-150V.
Do not reverse-connect battery terminals. Ensure power is off during installation. Install DC circuit breakers on input/output terminals. -
