Votronic MPP165, MPP250, MPP350, MPP430 Duo for 12 VDC

The Votronic MPP Duo range are advanced MPPT type Solar Controllers that can charge two different battery banks at once from the same Solar Panel/s.
Ideal for Motorhomes and Boats where you have an engine battery and a house battery. Votronic MPP Duo controllers have an electronic protection against overcharging, overload, overheating and reverse currents at night.
They have 2 battery charging ports for charging 2 separate battery banks simultaneously with one bank being charged fully, and the other receiving a trickle charge.
Ideal for keeping your house batteries at full, and making sure your start battery is full also. Adjustable charging programs to suit flooded acid, Gel and AGM batteries. The MPP165, MPP250, and MPP 350 now come with programs for most types of Lithium Batteries too.
LEDs to indicate the charging state:(Full, >80%, Charging MPPT mode, Low Voltage). Temperature compensation when used with the optional Temperature Sensor.
Note: must be used on a 12V system.
