How to turn a MPPT charger off to stop overcharging lithium batteries

With Lithium batteries you need to not keep them full charged for long periods. So you need to disable the solar chargers. There is command in VE.direct to do this (ID 0x2000 device mode charger off) but the manual says this should only be used for maintenance. If this is true how should you turn the charger off? You could reduce the charge current or voltage.

You set it properly (charging voltages and so on).

You can also use the remote on/off, if you want.
