Steca Power Tarom
Description
Specially designed for industrial and outdoor applications, the Steca Power Tarom comes in an IP 65 housing made of powder-coated steel.
This solar charge controller can regulate large systems at three voltage levels (12 V, 24 V, 48 V). The Steca Power Tarom is based on Steca Tarom controller technology. Connected in parallel, several controllers of this series can be operated via a conventional DC bus in a simple solar home system or hybrid system.
