Store Solar Energy Efficiently with RW-L2.5 Lithium Batteries for Solar Power Storage

The RW-L2.5 from Deye ESS offers advanced lithium batteries for solar power storage. Utilizing safer cobalt-free lithium iron phosphate chemistry, it accumulates surplus daylight for nighttime use.

Each 2.56kWh LFP battery module provides 100Ah capacity to store renewable energy. Supporting 80A continuous discharge (100A peak), it reliably powers most household loads. Connect up to 32 RW-L2.5 units in parallel to achieve over 80kWh total lithium batteries for solar power storage capacity.

An integrated battery management system actively balances cells and includes crucial protections against issues like overcharging and short circuits. It enables convenient remote monitoring, control and firmware updating.

With natural air cooling and an IP23 rating, the compact RW-L2.5 operates from -4°F to 131°F. Wall mounting saves floor space while built-in handles simplify installation and service.

Whether starting small or building a high capacity lithium batteries for solar power storage system from day one, the modular RW-L2.5 scales to your needs. It stores surplus solar energy for overnight power or backup during grid failures.

The flexible RW-L2.5 lithium batteries for solar power storage system delivers:

  • 2.56kWh LFP modules
  • Up to 80kWh total capacity
  • 80A continuous / 100A peak discharge
  • Integrated battery monitoring and optimization
  • Wide temperature range
  • Streamlined installation and maintenance
