The SOLAR CONTROLLER Maximum 37.5A rating is based on a 30-amp total maximum short circuit current rating (Isc) from the solar
modules nameplate ratings. The National Electric Code species the PV equipment/system rating to be 125% of the maximum Isc from the
PV module ratings (1.25 times 30 = 37.5A). E.G. Three modules in parallel with an Isc of 7 amps each equal a total Isc input of 21 amps.
When selecting PV modules for use with the SOLAR CONTROLLER do not exceed a total nameplate Isc current of 30A. Solar modules
list the Isc amps on their nameplate label.
The controller will not work unless there is a battery connected to the Battery 1 terminals.
WARNING: When the photovoltaic (solar) panel is exposed to light, it supplies a dc voltage to this equipment.
1) Automatic cycle interface
Display: PV voltage, PV current, PV power, Battery voltage and Battery temperature
2) Clear the generated energy
Operation:
Step 1: Press the “SET” button and hold 5s under the PV power interface and the value is ashing.
Step 2: Press the “SET” button to clear the generated energy
