Solar Charge Controller SR 150 Duo

The VOTRONIC solar charge controller with shunt controller technology (SR) has a double battery charging output and overcharge protection for batteries. This charge controller is moisture protected and is well suited for use in the marine sector. The new series enables higher charging capacities and is now available with 4 charging characteristics, suitable for acid, gel and AGM batteries. Temperature compensation, display outputs for solar display and EBL complete the range of functions. The controller is also protected against overcharging, overheating and reverse discharge and is capable of compensating for voltage losses in the charging cable.
The controller is plug-in- ready for connection to VOTRONIC displays, such as the LCD solar computer S for a detailed display of charging current, battery voltage, generated solar capacity (Ah) or solar power (Wh).
