If you have a solar PV system of 3kw or above then a solar battery could be of great benefit to you. In most domestic systems the surplus PV energy is simply fed back into the national grid, with no benefit to you. Modern Lithium Ion batteries can store this surplus energy and release it in the evening, saving you buying electricity from the grid.
You still get paid your Fits for generating the energy, regardles of if you use it or export it and you significantly reduce your electricty bill.
Which system, AC or DC?
There are two common types of system, AC and DC. An AC system, can be retrofitted to an existing installation leaving the old inverter in place. In a DC coupled system a special Hybrid inverter is installed that both converts the DC solar power to AC for home use and charges the DC batteries.
No one hat fits all, and the existing system and your requirements are taken into account before deciding on the system design. Both use Lithium Ion batteries, that have 90 to 95% depth of discharge and often a 10 year warranty.
How much does it cost?
Well that really depends on your requirements and the storage capacity. There are a number of options, plus several manufacturers, so we would normally ask you a number of questions in order to establish your requirements. We install systems from GivEnergy, Sofar, Solis, and Victron Energy.
Some battery systems are scalable and you could start with 2 Pylons = 4.8kwh, and later perhaps add another totaling 7.2kwh of storage.
Up to 8 Pylon batteries can be coupled together. For large off grid systems a hub is required, allowing up to 56 Pylon batteries.

Do you want to import from the grid?
Some systems can charge the batteries overnight from the grid. This allows you to take advantage of cheap rate overnight electricity from suppliers like Octopus, charge your batteries and then discharge them when the electricity price has risen during the day. If you want to take advantage of this then we recommend systems from GivEnergy as the app is very informative and user-friendly.
We are approved installers for GivEnergy battery storage systems.
