See graph, showing a much flatter curve for the charge current vs disconnect voltage. The minimum SOC is parameter is configured in the CCGX. And it is also being updated daily by the BatteryLife algorithm. For a household with one family, the MultiPlus xx/3000 can already manage nearly all appliances, when not more than one of them is running at the same time.
Just click on the file on your computer, and copy it (drag-and-drop) to the appropriate NOOK GlowLight Plus folder. To transfer files from a Mac, you must first install the Android File Transfer application on your computer. And select that battery or battery monitor as the System Battery Monitor in the Settings → System Setup Menu. And also making a system without PV Inverters, thus only MPPT Charge Controllers is perfectly possible.
This includes the Victron 12.8V lithium batteries, and therefore it is also mandatory to enable BatteryLife for those batteries. In case of mains failure, it is best to have spare energy available to power the loads from the battery. The Sustain level is 12.5V for lithium batteries. When the system as a whole produces power (PV power exceeds consumption), the Multis on the phases with a net power production will be set to charge the battery. The curve can be adjusted in the assistant.
