Omnicharge Solar Charge Controller 100-20

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.
