Energy Storage for Solar Applications

Reliable and efficient battery solutions for Commercial & Industrial (C&I) and Off-Grid solar projects.

Maximize Your Solar Investment with Robust Storage

In the solar energy sector, reliable storage is not just an option—it's a necessity. Whether for ensuring energy availability in off-grid systems or for optimizing self-consumption and providing backup in commercial installations, our batteries are designed to deliver maximum performance and longevity.

Key Applications

Commercial & Industrial (C&I) Self-Consumption

Reduce electricity costs and dependence on the grid by storing excess solar energy generated during the day for use during peak hours or at night. Our solutions ensure a stable power supply for your business operations.

Off-Grid & Remote Systems

Provide continuous and reliable power to remote homes, telecommunication towers, or rural infrastructure where the grid is not available. Our deep-cycle batteries are built to withstand demanding daily charge-discharge cycles.

Grid Backup & Peak Shaving

Protect your facilities from power outages and reduce demand charges by using stored energy during peak consumption periods. Our batteries offer a seamless transition and a secure energy reserve.

Works With the Inverter You Already Have

Rekoser batteries are not tied to any inverter brand. Off-grid, hybrid or grid-tied with storage: what matters is that the inverter's battery voltage matches the bank and that it has a charge profile for the technology you choose.

Lead-acid batteries work with any inverter that offers an AGM, GEL or flooded charge profile. The BMS of our rack lithium batteries communicates over RS485, RS232 and SMBus: send us your inverter model and we will confirm compatibility before you order.
