EG4 WallMount Batteries
Indoor or Outdoor WallMount?
Put the 314Ah Indoor in a garage, utility room or basement, on the wall or on the floor. Its IP20 enclosure belongs out of the weather. The All Weather models carry IP65 and IP67 ratings and heat themselves in the cold, so they can hang on an outside wall and keep the battery out of your living space.
Plan the lift either way. Each WallMount weighs 290 to 310 lbs (133 to 140 kg), so line up a second set of hands or a lift before install day.

EG4 Battery FAQ
EG4 lists up to 32 WallMount 314Ah All Weather batteries in parallel, which is over 500kWh of storage. Your inverter's battery limits and your cabling set the practical size, so plan them together.
The batteries themselves carry UL 1973 and UL 9540A. UL 9540 covers the complete system, and EG4 publishes certificates for specific pairings, such as the FlexBOSS18 with WallMount batteries. If you're pulling a permit, order the exact inverter and battery named on the certificate.
EG4 backs the WallMount 314Ah Indoor, WallMount 314Ah All Weather and WallMount All Weather 280Ah with a 10-year warranty.
Every WallMount model here heats itself automatically when temperatures drop. That built-in heating is what lets the All Weather models live on an outside wall in cold climates.
EG4 lists closed-loop communication for the WallMount All Weather 280Ah with EG4, Victron and Sol-Ark inverters, among others, and the 314Ah models auto-address with EG4 inverters. For any other pairing, check the battery protocol against your inverter before you order.
