Steca Solarix 2020-x2

Dual battery charge controller

Description

The Steca Solarix 2020-x2 is a state-of-the-art dual battery charge controller that is ideal for use in the leisure sector. It has a solar module input that is suitable for all 36-cell solar modules in 12 V systems and for all 72-cell crystalline solar modules in 24 V systems. Both the main battery and the starter battery are permanently and simultaneously charged by the solar module. In the process, 90 percent of the available power flows into the main battery, while the auxiliary battery is kept at the full charge level with 10 percent of the power.

The Steca PA LCD1 remote display can be used to change the distribution of the charging power. The charge controller has a powerful load output that is only fed from the main battery. The charge controller has a USB charging socket that can be used to charge smartphones and tablets. The Steca PA LCD1 remote display can be optionally connected.
