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.
Up to 15 variotrack in parallel on the same communication bus (75kW)
4 step charger fully programmable for longer battery life
Optimal usage in an xtender system with synchronized battery management
