LG Chem has recently released a range of high voltage (400V) batteries comprising the RESU7H and RESU10H models. Convenient, performant and safe, the RESU high voltage batteries are compatible with the best inverter brands on the market.

Become electricity-independent

Charging your battery during off-peak times and discharge it during peak times saves you money on your power bill. The RESU collects the excess power produced by your PV system during the day and allows you to use it at night, when your solar panels are no longer generating electricity. This surplus energy also comes in handy in the event of a blackout, providing you with back-up power.



  • Convenience: The RESU high voltage can be installed inside or outside, on a wall or on the ground. LG Chem has simplified the inverter connections to make the installation shorter and more affordable.
  • Performance: With continuous power, DC round-trip efficiency, and greater durability, the RESU high voltage is a high-end product.
  • Safety: RESU high voltage batteries possess the same safety-record technology as LG car batteries and all relevant international standard certifications.


Compatible inverters

Both of these batteries are compatible with the SolarEdge StorEdge interface and inverter. In addition, Fronius has confirmed that the Symo Hybrid would be compatible with the new LG Chem models in 3 to 6 months. Finally, they are also compatible with the SMA Sunny Boy Storage 2.5 but there might be power output limitations.
