If you have set the power in the "Family Load Setting" to 0 W, when the battery is charged to 90%, the charging power will decrease to protect the battery, in which case the photovoltaic power will also decrease.

If your Solarbank E1600 is working with the MI80 microinverter, we recommend that you set the "Priority Charging Percentage" to 90% so that the microinverter will run at a minimum power output of 100 W, and the remaining power of the photovoltaic panel will be used to charge the battery.
