Full rated output not reached
There are a few reasons why the Multi RS19 Solar is not reaching its full rated output.
Some of these reasons have already been explained in the chapter: “The batteries take too long to charge, are undercharged or charge current less than expected”. Some additional reasons are explained in this paragraph.
PV Array too small
If the PV array power rating is less than the solar charger nominal power rating, the solar charger cannot output more power than the connected solar array can provide.
