I have a IP22 to charge a bank of Battle Born Lithium batteries. On its own it works great. But when I join it an existing VE.smart network with a MPPT 100/30 and MPPT 100/50 solar charger, plus a BMV-712 battery monitor, it all goes wrong. As soon as I join the network the absorption voltage goes from 14.4V (which is correct) to 16.32V. Oops. That is not good. When I leave the network, all is well again. This test was done with the two MPPT chargers not doing anything (no sun on the solar panels). Anyone have any idea?
Thanks for all your insights!
Here's the weird Absorption voltage of 16.32V
Joined this VE.Smart network
Here's when not in the network, all is fine
Setting I use for the IP22
