Have the ability to use most or all of your generation - your energy costs less than importing grid energy.Get security for the future - from power cuts and rising energy bills.We run regular training courses for installers on this topic and can provide recommendations: Not all installers are familiar with the issues and benefits of energy storage. These can be included in inverter/charger.Extra protection relays are required to enable AC loads to be run either from grid or from the battery and to provide a new neutral earth connection.Allows operation in event of a power cut.Back-up may be possible with additional switchgearĬ) AC Coupled Energy Storage with Back-up.Possible to charge the battery from cheap rate electricity.There is no effect on the PV feed in tariff.An additional battery inverter/charger is required to convert battery power to 230 Vac and vice versa.Here the battery is connected on the AC side of the solar inverter.Usually no operation in the event of a power cut.Not possible to charge the battery from cheap rate electricity.No requirement to inform the DNO about changes to the system connected to the grid.There is some (slight) reduction in the PV feed in tariff due to energy used in battery charge/discharge process.A high voltage battery (to match PV voltage) is used to store the energy when it’s generated for when it’s needed.Here the battery is connected on the PV side of the solar inverter.These can be broadly described as one of three types with the following features: a) DC Coupled Energy Storage See: On-Grid Solar PV Battery Storage Solutions For kits see: On-Grid Battery Storage Kits & Commercial Battery Storage Kits Types of Energy Storage Systems We offer several Energy Storage Solutions to suit different budgets and requirements. Some systems can also provide backup power in the event of grid failure. As electricity prices rise this sort of battery storage system will become more and more cost effective. Adding Storage to Grid Connected PV SystemsĪ large portion of the energy generated by a typical PV system will be exported to the grid and there is increasing demand for solutions to enable better use of this energy through the use of energy storage.Īdding battery storage enables this excess generation to be stored for use later when consumption is higher than generation.
