Variotrack™ MPPT charge controllers


When connected to solar panels and batteries, the solar charge controller VarioTrack automatically charges the batteries in an optimal way with all the available solar power using its algorithm for Maximum Power Point Tracking (MPPT).


Maximize the energy generated from solar panels through maximum power point tracking.

High conversion efficiency: 98%.

Increased battery life: 4-stage charge

Rugged and durable: designed to perform in harsh environmental conditions (IP54)

Can be installed up to 15 Variotrack™ in parallel

Low consumption: ON<5W, standby < 1W (in night time mode)

Display with 6 LEDs showing system status and current

Multifunctional display, programming and datalogging with RCC-02/-03

Can be integrated into a Xtender system with synchronized battery control

Easy and safe to install: fully protected against incorrect wiring

Electronical protections: reverse polarity, short circuit, overload, high temperature, overvoltage, night reverse current.
