Atlas ESS 10kWh LFP Energy Storage System - 24V


The Atlas ESS 10kWh is a floor-mounted, deep-cycle lithium iron phosphate (LFP) energy storage system (ESS) that is used to power loads for long periods (years) off-grid, but works just as well in grid-tied applications. As it is designed for long-term off-grid use, it is maintenance-free and intended to be repaired on-site.

The Atlas ESS features a revolutionary battery management system (BMS) that monitors the temperature and voltage of the cells the BMS cell board is attached to. Each cell board is connected to a relay controller that disconnects the battery module from the load if the cells are operated outside their specifications (determined by your charge controller's and inverter's settings). Currently the BMS in the Atlas ESS is the only one on the market with a safety certification (UL 508).


Assembling the Atlas ESS

The cabinet is shipped empty and can be moved by one person with a dolly. The batteries are shipped in their own protective boxes. All cables and parts to assemble the system are included. Assembly takes approximately 1 hour. After the system is assembled, it is connected to the charge controller or inverter (not included) just like any other deep-cycle battery. The charge controller and inverter settings need to be adjusted for lithium batteries. These settings are provided.

The National Electric Code (NEC) allows electricians to assemble an energy storage system if the BMS and all parts have safety certifications from a Nationally Recognized Test Lab (NRTL). Since every component in the Atlas ESS system meets this standard, you can hire an electrician to assemble the system if you choose.


Changing the Atlas ESS Voltage

After installation, it is possible to change the Atlas ESS 10kWh's voltage between 12V, 24V, and 48V. This feature provides great flexibility in that if your inverter fails, you are not limited to replacing it with a new inverter of the same voltage. The process of re-configuring the Atlas' voltage takes about 1 hour.

Optional Atlas ESS Accessories

For systems with complex equipment, consider upgrading the standard Relay Controller to the PLC Controller, with 2 or more relay outputs used to control other equipment in your power system. An optional Data Logger monitors and records system data that can be viewed on the internet. Data Logger requires the PLC Controller.
