Typical Household Appliances And Usage

The power required to run equipment in the home every day varies with each electrical device. Appliances such as microwaves, irons, toaster ovens and hair dryers require high current for short periods of time. Appliances such as televisions, computers, fans and refrigerators use low current for extended periods of time. For example if all of the following devices are used once a day for the stated time, the total usage will be less than 1,500 watt hours.  Installing solar battery storage with 4kWh of usable capacity could power many of your essential devices using free solar energy or energy purchased overnight at off-peak rates.

7 Reasons To Choose Battery Storage

Power Cuts

In the event of a power cut, your batteries will keep your essential appliances powered

Reduce Bills

A domestic battery storage system can dramatically reduce your energy bills.

For Everyone

Batteries can be installed in any property – with or without solar panels.

Price Protection

As energy prices continue to rise, you can protect yourself by having free or off-peak energy ready to deploy at peak times.

System Monitoring

Our battery storage systems come with FREE wifi monitoring, enabling you to monitor and manage your energy.

Government Support

The government, Ofgem and National Grid are all supportive of domestic energy storage and future financial incentives are likely.

FIT Unaffected

Don’t worry! If you are registered for the FIT, adding batteries will have no impact on your payments.

AC or DC

There are two possible solutions for domestic storage systems – AC or DC coupled.

AC-coupled systems are recommended as a retrofit solution (for those who have PV installed).  There is no impact of FIT revenues for those on a high rate (owing to charge/ discharge efficiency losses) and no need to replace the existing DC inverter.  They also open up the possibility of charging batteries from the grid to exploit peak/off-peak price differentials and therefore can be installed without PV.

DC-coupled systems would be preferred for new PV installs where the priority is to store surplus solar energy.  The round-trip efficiency is greater and any impact on FIT (at current rates) would be negligible.  Charging from the grid would still be possible but less efficient and would require a specific metering solution.
