Introducing the WallMount 314Ah Batteries!

EG4 is proud to announce the next generation of our WallMount batteries with our 314Ah Indoor and All Weather versions! On top of the capacity improvements over our previous batteries, the WallMount 314Ahs have newly developed B<S functions, including WiFi/Bluetooth connectivity, active cell balancing logic, compatibility with our other WallMount batteries, and much more. They utilize the same quick connection terminals for rapid installation but have an additional bolt-style terminal for adding any ring connection necessary (such as a a classic Chargeverter).

The WallMount 314Ah batteries are compatible with the 280Ah form factor, so they will slot into existing systems easily. They pair well with the FlexBOSS21 and 18kPV when looking for whole home ESS solutions.
