We have recently completed a quite complex ESS system, built of 18 MPPT solar chargers, 12 Quattros, OPzS battery bank, BMV-702 and a CCGX.
Only one MPPT charger is connected to CCGX with VE.Direct cable, the rest 17 chargers just charge the battery bank individually, without any communication.
For now, the “feed-in excess solarcharger power” is set to OFF, as it is not allowed. But soon this is about to change, and sometimes there is some energy surplus, which could be feed-in to the grid. But will this be possible, considering only one charger is connected to CCGX?
Many thanks and kind regards,
