5.0c, 8.0c, 6.6c, 8.8c, 10.10c
Description
The Steca Solsum is one of the best-selling charge controllers of all time. It is ideally suited for use in solar home systems with load currents of up to 10 A at 12 V/24 V and up to 240 Wp module output.
The Solsum-C generation has a completely protected printed circuit board and features an easy-to-understand display via two LEDs. This generation of charge controllers was also designed in such a way that the controllers can also be manufactured and repaired on site in large projects.
