Controlling loads via the multifunction relay or charging batteries depending on
the power production of the PV system
The multifunction relay can control loads or charge batteries power-dependently. To enable this
function, you must connect a contactor (K1) to the multifunction relay. The contactor (K1) switches
the operating current for the load on or off. If you want batteries to be charged depending on the
available power, the contactor activates or deactivates the charging of the batteries.

batteries
