Energy Storage

Energy Storage

Energy Storage enables you to capture and store the energy from your solar panels allowing you access to the free, abundant power of the sun and reduces your reliance on fossil fuels.

Tesla Powerwall

The Tesla Powerwall has 3 modes; a battery to store surplus Solar generated Electricity, Time of Use Charging & Back Up Power.

  • Increase self-consumption of Solar power generation: Powerwall can store surplus Solar energy during daylight hours and use that energy later in the evening when the sun is not shining.
  • Time of Use/Load shifting: Powerwall can charge during low rate periods when demand for electricity is lower and discharge during more expensive rate periods when electricity demand is higher.
  • Back-up power: In the event of a grid outage, Backup Gateway is now available to ensure your Powerwall continues to power your home or select circuits. Backup Gateway will also ensure your Solar PV system continues to generate energy during a power cut.

Stratford Energy Solutions take care of everything from system design, permitting and installation.

Powerwall consists of a 13.5 kWh lithium-ion battery pack, liquid thermal control system, an integrated inverter that can charge/discharge continuously upto 5kW and software that intelligently dispatches electricity when it’s needed most. The unit mounts seamlessly on a wall or on the ground, indoors or outdoors, and is connected to the grid to take advantage of low cost electricity, maximizing your opportunity for economic benefit.

Powerwall App Demo


The Eddi device acts as an automatic power controller that diverts surplus power to a designated area – normally a hot water heater, to save energy and minimise your utility bills.

Once installed, this system can reduce an average household’s energy bill by up to £250 per year.

The Eddi system is fitted with a clear, graphical LCD display that will detail your saving information.

Works as stand alone product with size array to heat your immersion heater, storage heater, under floor heating, towel rail or electric raditor. All with surplus power from your solar panels or wind turbine.

This controller really is the perfect addition to any PV or wind turbine installation.
