A: The UK needs a secure and reliable and balanced electricity supply 24 hours a day.

We also need to make more use of renewable energy resources, such as solar and wind, to reduce our reliance on non-renewable fossil fuels such as oil and gas however, it’s just not that easy to just switch over to using solar and wind for all our energy needs, WHY? The sun doesn’t always shine and the wind doesn’t always gust meaning that the energy supply can be intermittent.

The solution to this problem lies in battery storage. By storing the energy generated from solar and wind power in reliable, powerful batteries, we can have a power supply that is available 24/7: – without costing the Earth.

A: A battery System that you own is the answer to greater grid independence, reduced electrical costs and in the event of a power cut the energy storage system will restore critical loads to the home.

Battery storage will complement your solar PV system by storing excess solar energy in the day that usually would be sent to the grid, instead the FREE energy that was stored during the day can be used in the evening for FREE

A: Yes. We’re offering our home battery storage system to old and new customers, If you already own a Solar PV system and just want to add a battery storage system, or if you require a complete hybrid solar PV and battery storage system.

A: Our hybrid battery storage system is compatible from 3kWp to 4kWp solar PV systems and comes with multi point tracking as standard meaning our hybrid inverter will work with multiple roof installations.

A: Our hybrid battery storage system is combatable with all solar panels so is ideal with retro-fit applications, we can replace your ageing inverter with our state of the art hybrid which will work with your existing solar installations from 3kWp – 4kWp solar PV systems and comes with multi point tracking as standard meaning our hybrid will work with multiple roof installations.

A: Our battery storage systems are stackable from 2.4kWh to 9.6kWh, each battery compartment holds two battery units of 2.4kWh, So just connect and grow your system from 2.4kWh / 4.8kWh / 7.2kWh / 9.6kWh

A: Unlike most companies we choose to advertise our prices, which can be found on our website or at

A: The benefits a household will receive will depend on a number of factors including your location, the size of your solar power system and your energy plan.

Our battery storage system can store excess solar-generated energy from a solar system, or energy sourced from the grid, for use at a later time.

The stored energy can be used for FREE instead of importing electricity from the grid, so depending on your electricity tariff, you may be able to take advantage of using your battery when prices are highest.

A: We provide a 10 year warranty for our battery storage system which includes 4000 battery cycle life.

A: Our battery Packs are guaranteed to last a minimum of 4000 cycles, So based on one full cycle per day this would be 10.95 years however it would be very rare that a typical home would do a full cycle on a day to day basis, because of short days in the winter and very long days of daylight in the summer a typical cycle pattern per year would be around 260 full cycles per annum meaning the expected lifetime would be around 15 years.

A: YES, At the battery cells end of life, we can replace your modules at a fraction of today’s lithium ion costs without taking the enclosure, inverter and conduit off the wall.

The system is designed for ease of service and future upgrades making the system future proof.

A: The whole system carries a warranty for a minimum of ten years or 4000 cycles.

A: Battery storage’ lets you store the surplus solar electricity, instead of exporting it to the grid. Battery storage lets you use more of your solar PV system’s output ( ‘increases ‘self-consumption’). This reduces the amount of grid electricity you need to buy, saving you money on your electricity bill.

During the day:
• the solar PV system generates solar electricity
• the battery storage system will check if all the generation is being used to power your lights and appliances
• if you’re not using all the electricity that the solar PV system is generating, then the system will ensure that any surplus energy is used to charge the battery
• once the battery is fully charged, if there is still more solar electricity being generated, this will be exported to the grid

In the evening or at time of low solar generation:
• the solar PV panels have a reduced output
• the battery system can discharge the stored electricity, providing you with renewable-generated electricity at no additional cost
• once the battery is discharged, if you need to use more electricity, you buy it from your electricity supplier
• depending on what energy plan you are on, our system can be programmed to charge from the grid at of peak times.

A: Yes: System sizing systems is important to enable yourself to get the best return of investment back within the quickest time frame, So its slightly more complicated than just adding batteries.

Typically, an average home uses around 12.5kWhs per day or 4,500kWhrs per annum.
Most homes that have existing solar PV have from 2.0kWp to 4kWp installed which can generate anything from 1800kWhrs to 4000kWhrs per annum which means there is only so much generated energy you can store.

DECC (department of energy and Climate Change) tell us that we typically only use between 20% and 30% of rooftop solar energy, with intelligent system sizing we can bring the level of self-consumption up to 70% / 80% and the levels of imported energy to a bare minimum.

A: No: all equipment is supplied with our battery storage system and will be installed within the day, system monitoring is included as standard and will be paired to your broadband router on the day of installation.

A: Yes, Our system is future proof and can be set to be enable to charge the battery’s with energy delivered from the grid at off peak times, and automatically transfer to battery power at peak times, in the event that TOU’s (time of use tariffs) become popular.

A: The battery storage system is designed to be wall mounted or ground mounted, Our certified installers will talk you through appropriate locations during a pre-installation site inspection at you home, nothing will be installed without full and final approval by the householder.

A: YES our system will restore critical loads, automatically in the event of a power cut, providing there is sufficient back-up.

A: You won’t be able to attach/plug in other devices directly to the battery storage system to charge, however the battery storage system will deliver its stored energy through your home’s electrical points.

A: Our battery storage system will work ON or OFF Grid “Just add Solar”

A: Yes, by storing solar energy and using it in the evening you are offsetting what in most cases are fossil fuel generated electrons.

A: Unfortunately, at the moment we do not offer finance, however we are actively looking for a suitable lender with suitable rates, and self-financing options.
