The variotrack MPPT solar charge controller maximizes the energy generated by charging the batteries in an optimal way. The accuracy of the Maximum Power Point Tracking (MPPT) algorithm, the high peak efficiency and low internal consumption ensure an optimal valorisation of the energy produced by the PV modules to all types of battery technology.



Easy and safe commissioning with full protection against incorrect wiring

Low self-consumption: <1W in night time mode

Display with 7 LEDs showing status and current
