System Size
What is the size of your PV array in kWp (e.g. 4kW)? Please select the closest value to your actual system capacity.
PV Installed
Are you looking to retro-fit batteries to a PV system, or do you want to install a batteries without solar for Economy 7 charging?
You have a PV system
You don't have a PV system
Economy 7/10
Are you on an Economy 7 or Economy 10 (or similar) tariff? This is not a requirement if the intention is to store surplus solar energy; however, if you plan to install batteries without solar you will require a time of use tariff in order to benefit.
WiFi Monitoring
Do you require a WiFi adapter to allow for remote system monitoring via app or web portal?
Storage Capacity
What is the amount (kWh) of storage capacity you require? It is not essential at this point that you decide on the storage capacity of the batteries as this can always be determined later.
Final cost (including VAT)
The final estimated fully installed price (including VAT) is:
Summary (for guidance only). All prices include VAT (charged at 20%) and show as additions to the base price.

Why Battery Storage?
There are many reasons why you would install a battery storage system in your home. If you have a PV array already in place, then it is likely that you are exporting up to 80% of that energy back to the grid. This is your energy that you have generated for free – and you get paid for generating that energy regardless of whether you use it or export it. By storing this surplus production for use later in the day you can increase ‘self-consumption’ to in excess of 80%, drastically reducing your reliance on the grid and driving down your energy bills. Switch to solar battery storage today.
No Solar? No Problem!
Domestic energy storage is not just for those that have generation assets like solar panels. You can install a battery system and benefit from ‘rate arbitrage’ – charging your batteries overnight on Economy7 and using that energy during peak periods; reducing your bills and offering protection against future energy price rises. All of our systems also have ‘Emergency Power Supply’ functionality – an option that will protect you against power outages.

We Choose Our Brands Carefully
Eco7 consider the reliability of its products, service and after sales a priority, so we chose our partners very carefully. We choose partners that are financially strong, strategically placed and are able to offer dedicated UK end user support and service. This is why we have chosen SolaX and Triple Power as our battery storage and battery storage manufacturing partners; offering market leading storage solutions suitable for every application.
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.
Run Time Chart
How much energy do appliances actually use?
| Devices | Watts | Time (Minutes) | Usage (Wh) |
|---|---|---|---|
| Microwave | 1200 | 15 | 300 |
| Kettle | 1200 | 7 | 130 |
| Television | 65 | 120 | 130 |
| Fan | 35 | 180 | 105 |
| Computer | 50 | 180 | 150 |
Battery Options
Eco7 offer a number of battery solutions. We recommend the TriplePower battery, offering compatibility with the full range of SolaX inverters/charge controllers. It is the most widely deployed battery solution in the UK to date and is offered with a solid 10 year warranty. Eco7 can also offer the SolaX/LG (dual branded solution) on DC systems, as well as offerings from BYD, Pylontech and LG Chem.
Eco7 only install the leading battery storage solutions including the AC Charger from SolaX
7 Reasons To Choose Battery Storage
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.
