We recommend starting with 12kWh storage capacity with a 3kw inverter. As the batteries are modular lithium units you can add more if you want at a later date. Our systems range in capacity from 2.4kWh to 47.5kWh.

We aim to achieve a turn around of 30 days. Depending on what brand of system you choose, lead times may vary.

You can take advantage of your Octopus Go or Economy 7 tariff with the battery system, charging it at night when the unit rate is cheaper, and using it during the day when the rate is higher.

Octopus Go: You can benefit from Grid charging during the night-time if you are on Octopus Go. If you are on the four-hour Octopus Go tariff, then you will need a rechargeable storage capacity of 12 kWh to achieve annual electricity savings of £1401. If you are on the six-hour Octopus Go tariff you can save £2102 per year, and you will need rechargeable storage capacity of 18kWh. Economy 7: You can benefit from Grid charging during the night-time if you are on Economy 7. If you are on the 7-hour Economy 7 tariff then you will need a rechargeable storage capacity of 21kWh to achieve annual electricity savings of £2452.

This will be set up for you as part of the installation process. You will be provided with login credentials and app information, as well as a tutorial to navigate the monitoring platform, including setting forced battery charge settings during low cost hours.

For Octopus Go customers utilosing cheaper night rates, our 14.6kWh storage system will save £3.50 per day at today's prices, which is £1275 a year, payback about 6 years. A typical system with 14.6kWh can save owners £3.50 per day at today prices, £1100 a year, with a payback of about 6 years.

We can set up EPS power supply from your battery system to provide power during a power cut, to either a double socket, or to critical circuits in the house. Please get in touch to explain your requirements and we can quote accordingly.
