STECA Power Tarom 4140 Solar Charge Controller 48V 140A

STECA Power Tarom 4140 Solar Charge Controller – 48V 140A

Specially designed for industrial and outdoor applications, the STECA Power Tarom 4140 comes in an IP65 housing made of powder-coated steel. This solar charge controller regulates large 48V systems with 140A module current — the most powerful model in the Power Tarom series. 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.
