SolarEdge Technologies ‘StorEdge’ solution with power backup has been launched in European markets. SolarEdge’s StorEdge is a DC coupled storage solution that allows home owners to gain energy independence and stay powered even when grid power is down.

Problem

The majority of installed residential and commercial rooftop PV systems remain grid connected, which will not operate independently during electric/grid outages.

Solution

With StorEdge, unused solar energy is stored in a battery and used when needed to maximize self-consumption and reduce electricity bills. StorEdge also supports Time-of-Use management, which promotes energy consumption when electric demand from the grid is low (off-peak rates) and lower consumption when demand is high (peak rates). The backup function allows homeowners to store solar energy and use it during electric outages to power pre-selected devices.

Applications

Residential PV systems in European markets.

Platform

The SolarEdge single phase inverter with HD-Wave technology manages battery and system energy, in addition to its functionality as a DC-optimized PV inverter. Existing SolarEdge single phase systems can be upgraded to StorEdge. To add StorEdge to PV systems using the SolarEdge three phase inverter or a non-SolarEdge inverter, the StorEdge AC coupled single phase inverter may be used. The StorEdge interface is required in order to connect the high-voltage storage battery to the SolarEdge inverter. It supports easy installation and connection to the battery and SolarEdge energy meter. Connection to the inverter is also done in parallel to the PV strings
