How battery storage can work for you

1
You'll generate in the day.

Like normal, your solar system will continue to generate energy throughout the daylight and you'll use what's required.

2
You'll store the excess.

The energy which you don't use will feed in to your home battery (rather than selling it back to the grid for a tuppence)

3
You'll use the battery at night.

Rather than buying from the grid when the sun goes down, your home will run on your battery storage system.

Battery FAQ's

Home batteries fall under permitted development rights, and planning consent is not required to install one. If your property is located in a conservation area, listed, or a building of historical interest then you’ll need to seek approval from the relevant authorities before placing an order.
Most likely, yes. However the Heatable team will apply for this on your behalf and manage the process as part of your order and the installation process.
There are a range of different energy providers who offer 'off-peak' tariffs, for cheaper night time charging. We would recommended you look in to your tariff options prior to purchase. Heatable takes no responsibility for the tariffs which you may, or may not be able to get.
OFGEM have issued guidelines which approves installing a battery system to a property which is receiving payments from the FIT scheme to recover and store excess energy from your solar system. You wont be able to register for or claim SEG (smart export guarantee) for battery power exported to the grid if you’re already receiving FIT payments. Doing so could breach your FIT agreement.
Yes, we offer a 2 year workmanship warranty on all battery installations which is backed by HIES.
A typical battery installation takes one working day. More complex installations, however, may take slightly longer.
Yes, you can. You’ll need to have it uninstalled and re-installed by an approved technician. Heatable are able to assist with this.
The minimum warranty for all the batteries we install is 10 years. Some offer extended warranty cover. Details of individual product warranties can be found in the product details.
All of our batteries are fully IP rated for internal, or external installation. Your installation engineer will discuss your preferred location with you ahead of the works. If you have any specific requests, please contact the office ahead of ordering. New guidelines have recommended that batteries are not installed in main loft spaces.
