Solar batterys brands ( not top 10)

The most important thing when choosing an off-grid solar system is the correct selection of solar batteries. Batteries or accumulators are the ones that store the energy produced by the solar panels and enable the autonomy of the system when the Sun is not present. Solar batteries specifically designed for solar systems and that it is not desirable to use ordinary car or truck batteries. Below you can view our offer of solar panels bateries brands and choose the ideal one for your application or solar system. It is not clasical top 10 list ( I don’t believe in those top lists because I don’t know who voted 🙂   – it is the result of my research.  Energy storage products (batteries) are constantly being upgraded and improved.

Some technical characteristics

Main technical characteristic for a single storage unit are:  Max solar Input DC (kW),  Max. continuous solar output   Another important characteristics are stacked: continuous power, current and capacity
Battery storage capacity vary from 9 kWh up to 100 kWh. Off-grid starting current AC vary from 16 to 50 A. Some battery has load  management system. Battery are usually made from Lithium. Solar strorages location could  be Indoor or Outdoor. Warranty should be from 5 years an up, usually 10. Each of the battery have to have at least 1500 cycles (one cycle means one charge and one discharge) at 50 % capacity. Batteries are usually make according to GEL and AGM technology, which means that they do not have liquid electrolyte and they do not need to be maintained and their life span is extended.Average lifetime could be 6000 cycles (one per day) which means 15 year of reliable work.
