I have 2 MPPT chargers (75/15 and 100/20) running in parallel and connected to a BMV 712 via the VE network. One charger receives both the current and the voltage of the battery from the BMV, the other only the current. The displayed voltage is then significantly different on both chargers. Example: BMV shows 13.3 V, MPPT 1 also shows about 13.3 V, MPPT 2 - which does not receive the voltage data shows 14.1 V. Both chargers do not work synchronously. MPPT 1 is in bulk mode, while MPPT 2 is in absorption mode. What can be the reason for this?
You might want to unjoin the network.
Then set up a new network from the BMV.
Then join both mppt’s to the BMV’s network.
Have I already tried. I have also switched off the MPPT’s alternately. The 75/15 doesn’t never receive the current
Have you updated all the firmwares?
