Is it possible to set a charge limit by SOC my lifepo4 battery stays in the caravan and would love to store it at 40-60% and up it back to 100% couple days before we use it
while in storage it’s not connected to shore power
Cerbo gx
Multiplus 12/1600-70
Smart solar 100/20
Thank you
Easiest way is to run the battery to the charge level you want, then switch everything off, including solar. However it's not really necessary with LiFePO4.
The concept of storing partially charged is more applicable to other types of Lithium batteries. There's no direct way of setting a charge limit. You can trick things by reducing voltage settings, but it's not that easy. You may be able to do it by using Node-RED to switch off the MPPT via the Cerbo relay, not sure. Node red details are in the modifications space. But apart from helpful members there, it's not officially supported.
