Overview
The WallMount Indoor 280Ah batteries are tailored for low-voltage residential indoor energy storage needs. Utilizing lithium iron phosphate cells renowned for their superior safety performance, these batteries feature an intelligent Battery Management System (BMS). This BMS offers real-time monitoring and recording of cell voltage, module current, voltage, and temperature. Additionally, it incorporates a passive balance function and an advanced battery control method, enhancing the overall performance of the battery pack.
ON-BOARD LCD TOUCH SCREEN
Clear BMS monitoring and user-friendly closed-loop communications selection with popular inverters such as EG4, Schneider, Sol-Ark, Victron, Growatt, Megarevo, Luxpower, and Deye.
DUAL ON-BOARD FIRE ARRESTORS
Ensures fail-safe protection against thermal runaway scenarios.
INTEGRATED SELF-HEATING FEATURE
Built-in internal heating maintains optimal cell operation even in cold conditions.
INTEGRATED BUSBARS
Equipped with 600A internal busbars featuring multiple terminals (4 positive & 4 negative), eliminating the need for external busbars when connecting batteries and/or multiple inverters.
INNOVATIVE EMERGENCY STOP FUNCTION
Optional ESS disconnect enables the shutdown of all batteries and inverters (with rapid shutdown capability) instantly with the push of a button.
THE PERFECT PARTNER TO EG4 INVERTERS
Optional conduit box seamlessly connects to EG4 inverter ports for streamlined installation. For other inverters or standalone battery setups, conduit box plugs should be installed.
