Nationwide Solar & Battery Installations Across the UK

We provide professional solar and battery storage installations nationwide across most areas of the UK. Every system is fully certified and installed by qualified engineers, giving you peace of mind and long-term reliability.

Pricing and Deposit Information

• A £750 refundable deposit is required to begin the installation process and, where necessary, to submit your DNO (Distribution Network Operator) application.
• The balance payment is due before delivery of the system. (Please note: any date shown at checkout is only an estimate.)
• The listed price includes:
• Full installation
• DNO application submission
• MCS certification
• 2-year workmanship warranty
• Delivery of all components

In some cases, a new sub-board or RCD board may be required. If so, this will be quoted separately or charged on the day if installers need to purchase upgrade parts.

Optional Backup Power Upgrades

For properties in remote UK locations or where backup power is required, additional electrical components can be installed:

• Full house backup – With either automatic switchover or manual switchover, depending on system size and capacity.
• Critical load backup – Using the EPS output and a second consumer unit to supply essential circuits only (e.g. lighting, refrigeration, Wi-Fi, medical equipment).

Backup upgrade options are available on our installed packages page here. These can be added to your order after your deposit is paid, with payment only due once components are ready for installation.

Steps to Proceed After Deposit Payment

To move forward with your installation, please provide:

6.                  Your MPAN number (found on your electricity bill).

7.                  Photos of the proposed installation space for the battery system, with a brief description of the location.

8.                  Photos of your consumer unit, along with a description of its position relative to the battery system location.

9.                  Photos of your existing solar inverter setup (if applicable).

Please note: This is a DC battery system which is only for adding to an existing solar pv system. Efficiency is greater than an AC coupled system as electricity is only converted once rather than 3 times. However, it can not be used on its own to charge from the grid without a solar inverter.

EcoFlow PowerOcean DC Battery System for Solar PV

The EcoFlow PowerOcean is a high-performance DC battery system designed to expand existing solar PV installations. Unlike AC-coupled systems, it offers higher efficiency as electricity is converted only once, reducing energy losses. Note: this system cannot charge from the grid independently without a compatible solar inverter.

Built for durability, safety, and scalability, the PowerOcean integrates advanced LFP battery technology, fire prevention modules, and an IP65-certified enclosure, making it ideal for UK homes seeking reliable solar energy storage.
