The VE BUS is giving a low battery alarm while the battery voltage is normal in the BMS. See picture below. There was a high current draw event and after the VE BUS voltage started swinging low when the inverter mode kicks in. Any ideas how to resolve this? The system is a split phase with 2 Quattro's and BYD battery bank of 7.5 kWh.
Hi M. It might be time to drag out that trusty $20 multimeter. Firstly to confirm those V's, and then to determine where the difference is occurring in your circuits. Could be a 'dry' connector or a dicky breaker or fuse, something like that. Hot spots? On both +ve and -ve circuits.
Your wires should be quite large, and probably easily checked.
