LG Chem RESU H (High Voltage) 7 | 10 SolarEdge StorEdge AC coupled inverter SolarEdge StorEdge Interface SolarEdge Energy Meter with Modbus Connection Screened Twisted Pair Communication CableSolarEdge’s StorEdge DC coupled storage solution can be used to increase energy independence for homeowners by utilising a battery to store and supply power as needed. To optimise self-consumption, the battery is automatically charged and discharged to meet consumption needs and reduce the amount of power purchased from the grid.
The solution is based on a single inverter for both PV and storage. Existing SolarEdge systems can be upgraded to the StorEdge solution.
System schematic
Features
More Energy
- DC coupled solution allows high system efficiency
- PV power is stored directly in the battery
- No additional conversions from AC to DC and back to AC
- Module-level power optimization for more power harvesting
Simple Design & Installation
- A single inverter for both PV and on-grid storage
- Outdoor installation allows flexibility in battery location
- No special wires are required -> utilizes the same PV cables
Full Visibility and Easy Maintenance
- Monitor the battery status, PV production, and self-consumption data
- Smarter energy consumption to reduce electricity bill
- Remote access to inverter/battery software
Enhanced Safety
- PV array and battery voltage designed to reduce to a safe voltage upon AC shut down
What's needed (in addition to a SolarEdge PV system):
- A StorEdge interface
- HV Battery - eg. LG Chem HV to store the energy
- SolarEdge Wattnode electricity meter & current transformer

SolarEdge Energy Meter with Modbus Connection
The SolarEdge Energy Meter with Modbus Connection measures production, consumption and feed-in to enable export control or limiting (supports G-100 in UK).
A wide range of CTs (current transformers) are available to support residential and commercial installations. Connection to the inverter or Control and Communication Gateway is achieved via RS485.
Highlights:
- High accuracy meter readings (up to 0.5%) for production/consumption readings
- Supplies meter readings to the inverter for Feed-in Limitation
- Suitable for residential, commercial and utility-size installations
- Small and easy to install
Safety Note: CTs must never be operated open-circuit (secondary coil wires disconnected) once installed, whilst on a current-carrying conductor, as dangerously high voltages may occur under these circumstances.
