EG4 WallMount Indoor Battery 280Ah

Coverage and limitations

The firmware and Cerbo communication notes cover different questions about the Indoor 280Ah battery. Separate comparisons distinguish it from the 314Ah Indoor model and rack batteries, rather than treating every WallMount or EG4 battery as interchangeable.
