The OCS family offers solutions for PV array maximum power levels from 260Wp up to 3.6kWp and battery system voltages of 12V up to 48V.

Very low self consumption and high resolution power control circuits ensure excellent performance at sunrise and low light levels.

The OCS controllers are highly efficient, reaching peak efficiency levels of respectively 98% and 99% for the conversion and MPPT sections. This way PV power will be transferred to your batteries with minimum losses. But this also means that no cooling fans are needed and that the OCS controllers are running at respectable internal temperatures, resulting in a long lifetime.

Many protections are built-in, like for reverse battery- and PV connection, output short circuit, input power overload and high temperatures.

There are selectable charge programs available for Lithium, AGM, GEL and Flooded batteries. Additionally, a user defined charge program can also be selected and edited to fit your desired battery type.

Each OCS controller can be configured and readout using our Dashboard Mobile app for iOS and Android devices. This includes the display of 300 days of extensive history data.

All OCS controllers are very easy to install and come with clear instructions. A battery temperature sensor is included as standard for the OCS150-60 and 250-70 models.
