StorEdge Battery System

Bookmark and Share

SolarEdge’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.

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 StorEdge Interface

Allows connection of the LG Chem RESU H battery to a SolarEdge inverter.

  • Simple installation and connectivity of the battery and the SolarEdge Meter
  • Connects to the SolarEdge inverter in parallel to the PV strings
  • Designed to eliminate DC voltage and current during installation, maintenance, and firefighting
SolarEdge StorEdge Interface

SolarEdge StorEdge 3-Phase Inverters

Ideal solution for three phase installations with battery storage.

A hybrid inverter that connects to solar PV and 48V batteries. Suitable for indoor or outdoor installations, inverter models range from 5kW to 10kW.

  • Simple installation with single inverter for managing both PV production and battery storage
  • Can be installed with or without solar as DC or AC coupled battery storage
  • Quick and easy inverter commissioning directly from a smartphone using the SolarEdge SetApp
  • Designed to eliminate high voltage during installation, maintenance or firefighting for enhanced safety
  • Built-in module-level monitoring and full visibility of battery status, PV production, and self-consumption data
  • 12-year standard warranty extendable to up to 25 years
  • Compatible with BYD LVS Batteries

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.
