Batteries – is it possible to program lithium batteries to discharge at certain times? On good sunny days (sadly few and far between ) I often find that the batteries are still 50 or 60% charged at midnight, they then discharge during the night in the period of the cheap rate. Is there any way that the batteries BMS or the controls (Smart Solar charger that is linked to the inverter) can be programmed so that if say the batteries are 50% full at midnight then they will not discharge until say 6 AM. Ideally they will should be a further qualification that if the batteries are only 20% full at midnight then they will be charged from the grid during the cheap period
My system comprises a Victron Multi plus inverter – 48 /5000/70 smart solar charger MPPT 250/70/TR, Lynx 1000 distributor, cebo GX and two LEOCH 4.8 kWh lithium batteries
