Votronic SR 330 - Duo Dig Solar Charger

filler

Votronic Solar chargers are manufactured in various input capacities - this one is suitable for a solar panel set up with maximum capacity of 50-330 Wp & 0-21 A current.

The SR 330 Duo Dig Solar charger is a solar controller for a dual battery system enabling charging for both the leisure and starter battery. An essential component for solar charging systems which provides protection from overcharging your battery and protects your panel from reverse current flow.

This solar panel regulator is suitable for all types of Lead batteries (also for lead acid, GEL & AGM). Optimum charging is controlled by the integrated microprocessor to ensure fully automatic operation.

Features

Dual output channels allow for main leisure battery charging AND trickle charge top-up to your car battery
Both outputs incorporate overcharge protection & reverse current flow (avoiding battery discharging at night)
Option - a Votronic Solar Computer can be added to the configuration with a single cable connection to provide visibility of the solar charging status
