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.
