MasterVolt Solar Chargemaster Battery Charger/regulator

3-step charging method adjustable for all battery types and works with nearly all solar panels (PV-modules). Suitable for 12V and 24V. The charge controller protects the battery from being overcharged by the solar array and from being discharged too deeply by the load and it adjusts itself automatically to 12 V or 24 V system voltage. Push-button allows switching the load on and off. Features: Clear LCD display and graphics automatic night light detection and an extensive alarm system (buzzer). Automatically switches off load when battery current is low. A battery temperature sensor is standard designed to regulate the optimum charge voltage at each temperature to prolong the lifespan of the battery.
