Steca Solarix 2020-x2
Dual battery charge controller
- Two different battery types can be connected
- 12 V or 24 V voltage can be combined with main and auxiliary battery
- Extremely low own consumption (for example, supported by hibernation mode)
- Extensive programming and display options thanks to the remote display Steca PA LCD1
- Intuitive, fully graphical remote LCD





Description
The Steca Solarix 2020-x2 is a state-of-the-art dual battery charge controller that is ideal for use in leisure applications. It is equipped with a solar module input suitable for all 72-cell crystalline solar modules in 24 V systems and for all 36-cell solar modules in 12 V systems. Both main battery and starter battery are charged simultaneously and continuously by the solar module. 90 percent of the available power flows into the main battery while 10 percent of the power is retained to keep the auxiliary battery fully-charged.
The charge power split can be adapted using the Steca PA LCD1 remote display. The charge controller is equipped with a high-power load output fed by the main battery only. The charge controller has a USB charge socket, which can be used to charge smartphones and tablets. Connection of the Steca PA LCD1 remote display is optional.
