Choosing a Battery
The SOLAR CONTROLLER is suitable for use with lead acid batteries (vented,
GEL, or AGM type) as well as some lithium iron phosphate (LiFePO
4
) batteries
that are supplied with a Battery Management System (BMS). If using lithium ion,
it must be lithium iron phosphate (LiFePO
4
) chemistry with a BMS. No other
chemistries are compatible.
Lithium batteries typically have maximum allowed charge currents. These
maximums typically decrease in cold temperatures. SOLAR CONTROLLER does
not limit current for these restrictions, and system design of the solar array must
account for this.
Be sure to follow all battery manufacturer safety instructions.

DuraLite Kit Wiring Diagram
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 specifies 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) array is exposed to light, it
supplies a dc voltage to this equipment.
