Energy Storage System

Energy Storage System

Your energy comes in multiple ways, common forms such as radiation, chemical, kinetic and electricity can be stored within the systems. Others include gravitational potential, electrical potential and elevated temperature.

Energy storage does the job of converting energy from these forms that are difficult to store ormally, these are then stored conveniently or economically. Bulk energy storage is currently dominated by hydroelectric dams, both conventional as well as pumped.

You can store in your energy storage system, capturing energy that was once produced and can be used at a later date – this device is also known as an accumulator.

Some technologies provide short-term energy storage, while others can endure for much longer. However, this is may be due to the deal you are opting to go for.

Solar Panel Safety Systems

In the main, proper electrical commissioning procedures are among the best defences against latent fire or electrocution hazards – although once installed, ongoing and effective electrical testing is also vital both to prove the continuing safe installation of a PV system but also to verify ongoing functional performance over extended periods.

PV Plus

This is a faster return on investment for both new and existing installation. Simply have your Inverter isolator replaced with the Solar PV Plus. PV+ is a system loss compensator/grid voltage monitor. It has been designed to solve a specific problem – when your PV system is generating at full capacity, your inverter can go into over-voltage mode, which stops you generating electricity at all. This loss in generation can be as much as 25%.

  • Benefits of PV Plus
  • This generates up to 25% more electricity.
  • This allows your existing PV system to generate up to 25% more electricity.
  • Get up to 25% more Feed in Tariff.
  • While your inverter is in over-voltage mode you are not earning from the Feed in Tariff.
  • Easy to Install.
  • PV+ simply replaces your inverters AC Isolator and works with most PV systems.
  • Low cost investment.

What is energy storage system

Energy storage system is a simple way for storing excess solar power produce during the day, that is not consume by the house, for use at a later time rather than using energy from the national grid

Why would I want to store this energy?

This is simple a question of economics and security. The excess energy not use during the day is exported back to the grid you are paid a fixed amount, and the export tariff this is at present about 4.77p/KWHR.

However at evening, you would then ask to buy this energy back from the national grid at about 15p/KWHR, and average gap of 10p/KWHR. If you store this excess during the day, you can use it during the night, minimising anything you buy to as close to zero as possible.

What happens if there is a power cut?

During the day the storage inverter will energise, and supply the house grid which means the solar system will continue to generate, at night the solar inverter will power the whole house anyway, you will therefore be immune to power cuts.

Incase of a utility power outage, the hub will disconnect from the grid and continue to operate as the standalone system. Your solar system will continue to operate if there is a power outage.

Do I keep my feed in tariff?

Yes the FIT is still kept and you also paid an assumed 50% export amount, even though you are storing it.

Can it be retrofitted?

Yes, very easily.


A typical cost will depend on how big your solar system is. The cost is in between from £2400 to £4500 for a 4KW storage system, If your system is bigger than 4KW pv solar system, it will cost more.
