The most common type of battery used in energy storage systems is lithium-ion batteries. In fact, lithium-ion batteries make up 90% of the global grid battery storage market. A Lithium-ion battery is the type of battery that you are most likely to be familiar with. Lithium-ion batteries are used in cell phones and laptops.
Energy storage systems have become widely accepted as efficient ways of reducing reliance on fossil fuels and oftentimes, unreliable, utility providers. A battery energy storage system is the ideal way to capitalize on renewable energy sources, like solar energy.
According to the U.S. Department of Energy’s 2019 Energy Storage Technology and Cost Characterization Report, for a 4-hour energy storage system, lithium-ion batteries are the best option when you consider cost, performance, calendar and cycle life, and technology maturity.
An AC-coupled storage system is connected to the AC grid mains that service the property (that is, the lines coming in from the street).. You can think of this type of arrangement as a ‘two box’ solution – because there is one ‘box’ (inverter) for the solar panels, and another for the battery bank.
A battery energy storage system (BESS) or battery storage power station is a type of energy storage technology that uses a group of batteries to store electrical energy.
The main advantage of AC-coupled battery storage is that it is the easiest and generally more cost-effective way to retrofit batteries onto a pre-existing solar PV system (in most cases – check out our helper tool).

Types of Solar Batteries in 2024: A Comprehensive Guide
In AC-coupled systems, the solar energy needs to be inverted (changed from AC to DC, or vice versa) multiple times before it''s discharged from your battery into your home. Each time electricity is inverted, a little bit is lost in the process, making for a less efficient system. As such, AC-coupled systems typically have round-trip efficiency of around 85-90%, which …
