Wattstor FAQs

Do I need solar PV or another renewable energy system to take advantage of a Wattstor solution?

Yes, the WATTSTOR™ system saves electricity generated by your PV or other renewables systems for later use rather than exporting it to the grid.

How does the WATTSTOR™ work?

The energy storage system will divert surplus electricity into the battery to be used when the generation cannot supply all loads in the property.

How much electricity can I store in the batteries?

Wattstor can provide a range of battery solutions. Our most commonly installed systems can have a capacity from 2.5kWh up to 440kWh. A typical household is likely to use between 5kWh and 10kWh from sunset to sunrise.

How long is the warranty on a WATTSTOR™ system?

Our warranty periods can vary depending on the type of system being installed, but as standard, most products come with a minimum warranty period of 5 years. This can be increased to 10 years for a small fee.

How much electricity do I need to consume to make a WATTSTOR™ worth installing?

Wattstor can offer a wide range of battery systems suitable for many applications. If you are unsure if a battery system is right for you, contact us and we will advise you on the suitability of your property.

What happens when the batteries are full and I’m still generating electricity?

When the batteries are full and hot water tank is up to temperature, any surplus electricity is then sent to the grid. This can be avoided by adding additional batteries.

What happens if there is a power cut?

When the batteries are full, any surplus generation will be exported to the grid.

Can I increase the storage capacity?

Yes, our common systems are modular, and more capacity can be easily added.

Where can the WATTSTOR™ be installed?

The WATTSTOR can be located in any covered area, e.g. garage, utility room, external housing. Ideally, it should be sited as close as possible to the electricity meter or consumer unit. The Wattstor surveyor will be able to advise you.

Will I lose any FiT (Feed in Tariff) income?

No. For renewable systems up to 30kW capacity (90% of UK systems), the amount you export to the grid is not metered so no income will be lost.
