The LG Chem Renewable Energy Storage Unit (RESU) is one of the best battery storage units available on the market, and at a very competitive price. LG Chem is an industry leader in lithium-ion battery manufacturing and the quality and warranty are backed by the larger LG company which ensures a long-lasting product that delivers. The LG Chem battery can be coupled with a Victron inverter/charger or SolaX hybrid PV inverter/battery charger so it is suitable for both new and existing PV systems. It comes in three different sizes and up to two can be coupled together in a single box if more storage is required.
