Introduction

SolarEdge’s StorEdge™ DC coupled storage solution allows home owners to maximize self-consumption and to enable energy independence. Unused PV power is stored in a battery and used when needed to maximize self consumption. The solution is based on a single inverter for both PV and storage.

Can be added to existing PV systems using SolarEdge inverters.

Features

  • 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
  • A single inverter for both PV and on-grid storage
  • Outdoor installation allows flexibility in battery location
  • No special wires required - uses the same PV cables  with no high voltages & currents during installation and maintenance
  • PV array and battery voltage designed to reduce to safe voltage upon AC shut down
  • Monitor the battery status, PV production, and self-consumption data
  • Smarter energy consumption to reduce electricity bill
  • Remote access to inverter/battery software
  • Easy access to the inverter during maintenance (outdoor installation)

 The system consists of

  • A SolarEdge inverter and Power Optimisers - to connect the solar photovoltaic (PV) panels.
  • A StorEdge interface unit to control battery charging.
  • A high voltage battery - to store the energy when it’s generated, for use when it’s needed e.g. LG Chem RESU H.
  • SolarEdge Energy Meter for monitoring import/export to the grid.
  • Cabling and switchgear - for efficient and safe operation
Additional cost to end user from ~ £7,000 + Vat (compared to normal PV system)
