Steca Power Tarom

2070, 2140, 40 , 4110, 4140

Designed for industrial and outdoor applications, Steca Power
Tarom controllers come in a IP 65 powder painted steel enclosure
for the large power range (up to 8400 Wp) on three voltage levels
(12 V, 24 V, 48 V). Power Tarom controllers are based on the same
technology as the Steca Tarom controllers. If you connect them in
parallel on a common DC bus power line, several controllers operate
in one single PV or PV hybrid system in the range up to 20 kWp of
solar power.
(For more information about Steca hybrid systems see page 10)
