Energy storage

How it works

Energy storage is a bank of batteries that charge from your solar panels, wind turbines, or off a grid when there is excess capacity and rates are low. These systems can be utilized during power outages to ensure your home or business still has power or to even take the entire facility off grid. Energy storage provides several other benefits including the ability to reduce peak demand charges and frequency regulation. Today, energy storage can safely and economically power your home or business. There have been major cost reductions in recent years making these cost effective solutions, as well as major advances in both the software and battery technology, resulting in battery optimization, and stronger financial results.
