The EasySolar goes to Sustain Mode. At 4:00 in the morning a bigger Load switches on (washing machine). The reason for Sustain Mode is the Battery Voltage? Best regards Thomas

Sustain Mode EasySolar
Sustain, which Victron call absorption, is the fixed voltage part of a three or four phase charge cycle. Once voltage hits 14.4, AGM batteries are about 80% charged. Constant voltage completes the charge and current drops as it completes. Then the battery is held at a lower voltage, called float - charged, ready for action.
Sorry, but Sustain is not Absorption. Sustain is a protection mode for the Battery.
In ESS, sustain is triggered when the battery dips beneath the dynamic cutoff voltages.
Thanks, I found this text in the Victron documentation too. But what is the solution? In my screenshot the voltage is not so low, isnt it?
