STECA Power Tarom 2140 Solar Charge Controller 12/24V 140A

STECA Power Tarom 2140 Solar Charge Controller – 12/24V 140A

Specially designed for industrial and outdoor applications, the STECA Power Tarom 2140 comes in an IP65 housing made of powder-coated steel. This solar charge controller can regulate large systems at three voltage levels (12V, 24V, 48V). Based on Steca Tarom controller technology, several controllers of this series can be connected in parallel and operated via a conventional DC bus in a simple solar home system or hybrid system.
