SKU: SE G5. 3 Category:


Build a Massive 340kWh big solar battery bank with the SE-G5.3 systems for overnight storage or backup power.

This big solar battery bank can meet all your needs.

The SE-G5.3 from Deye ESS lets you easily scale up safe, reliable lithium iron phosphate batteries to over 300kWh.

Each 5.32kWh battery module offers 100A continuous discharge and 120A peak current, handling high power loads. Simply connect up to 64 units in parallel to achieve 340kWh total capacity – enough for most residential or commercial solar setups.

An integrated battery management system actively balances cells and prevents issues like overcharging or short circuits. It enables remote monitoring and firmware updates for convenient maintenance.

With natural air cooling and an IP20 rating, the compact SE-G5.3 operates from -20°C to 55°C. Wall mounting saves floor space while convenient handles simplify installation and serviceability.

Whether expanding an existing solar + storage system or building from scratch, the modular SE-G5.3 makes it straightforward to create a custom lithium iron phosphate battery bank. It stores surplus renewable energy for overnight power or backup during grid failures.

The SE-G5.3 big solar battery bank delivers:

  • 5.32kWh capacity per module
  • Scalable design up to 340kWh
  • 120A peak discharge current
  • Integrated battery management and monitoring
  • Wide operating temperature range
  • Compact size and flexible mounting

Invest in the modular, scalable SE-G5.3 big solar battery bank to build out your high capacity solar battery bank over time. Contact the Deye ESS team to customize the ideal storage solution.
