LG CHEM RESU Energy Storage System • Solar Electric Contractor In Seattle WA | (206) 557-4215

A LG Chem RESU Home Battery can store the extra energy generated from solar panels to use at a later time. Power your home with a Home Battery when the cost of energy is high or during a power outage and be independent from the electrical grid.

Why Should I Have a Home Battery?

  • Be prepared. Hurricanes, earthquakes and other natural disasters can unexpectedly cause a power outage and impact your family’s safety and security. Be prepared and power your home with the LG Home Battery RESU.
  • Utilize your surplus solar energy. Typical homes have high energy demands in the mornings and in the evenings but solar generation is highest mid-day. Without a Home Battery, much of the solar energy would be wasted since there isn’t a high demand for the power in the home. A Home Battery allows you to store solar overproduction in order to use it later on when your energy demands are the highest.
  • Cut back on your electricity bills. By fully using your solar energy, you will significantly cut back on your electricity bills.


The LG Chem battery comes with a 10 year warranty that is based on the battery’s remaining capacity and energy based on charge and discharge cycles. The warranty ensures storage capacity greater than 60% during this ten year period. This warranty far exceeds non-lithium batteries, which average a 2-5 year warranty period before the battery needs to be replaced. This increase in lifetime and efficiency has the potential to further decrease your system’s ROI and provide battery storage for a much longer period of time before a replacement becomes necessary.
