THE SOLAR REGULATOR REDARC solar regulators ensure that the power supplied by your solar panels is at the right voltage to charge your auxiliary batteries. REDARC solar regulators are PWM controlled and incorporate automatic system voltage detection. Our solar regulators are suitable for charging up to two separate battery banks and come in both 10 A and 20 A models which are capable of charging either 12 V or 24 V battery systems.

THE SOLAR REGULATOR Setting Modes NOTE: • The regulator will automatically sense the battery voltage. • A 24 V battery system must have 24 V solar panels and a 12 V battery system must have 12 V solar panels. 1. Press the Set button to start the mode select process. 2.
Fuse protection is required for wire and component protection in case of short circuit. Fuses are to be fitted as close as possible to the battery positive terminal. REDARC recommend using MIDI style bolt down fuses as they ensure a low resistance connection. The REDARC FK40 and FK60 fuse kits are recommended.
