Charge controller & display for solar systems


A charge controller is absolutely necessary for off grid solar systems for independent and self-sufficient power generation e.g. in mobile homes, caravans, campers, vans and sailboats.


SOLARA has a wide selection of charge controllers and displays for solar power systems for independent power supply.

Function of a charge controller

The charge controller is connected to the solar modules and the battery for overcharge protection. So that the consumers do not deep-discharge the battery, the charge controller, if there is no deep-charge protection on board, is also connected to it. The charge controller is thus the control center and an important protection for the solar system.


Charge controller can have additional functions

Some charge controllers have a temperature sensor, indication of the state of charge, charging current, load current, battery voltage, operating status of the solar system, warning signals and much more. SOLARA provides charge controller with a variety of additional functions.


Charge controllers are available in different versions

Charge controllers must be matched to the battery type. Charge controllers are available in different designs and qualities. SOLARA has a wide selection for all battery types and sizes of solar systems.

SOLARA Charge controllers - Ideal for charging batteries ith solar modules

The control center for all cases

We guarantee high reliability, the latest technology and ease of installation at low cost. The regulated PWM characteristic guarantees optimum charging. All Solara controllers are so-called series regulators (no shunt) and thus very efficient. The load output protects your battery from deep discharge. A large and informative LCD display shows the current system status. The SR350DUO also offers the possibility to charge two battery circuits.
