Works with Smart Tariffs including Octopus Energy

When combined with a Fox ESS battery, the Fox H3 PRO 20.0kW Hybrid has been designed to work seamlessly with smart energy tariffs. The first energy supplier to offer such a tariff is Octopus Energy, however the Fox ESS battery system works perfectly with any other energy provider.

Installation is Easy

The Fox H3 PRO Hybrid Inverter is designed to be easy to install to help save you time on installation. Flexible configuration, plug & play setup, built-in fuse protection.

Never Lose Power

With the Fox H3 PRO 20.0kW Hybrid you can ensure that you never go without power. An emergency power supply or ‘EPS’ port enables the inverter to work completely off-grid, meaning that any power you have stored in your batteries will now be used in the event of a power cut. Requires separate EPS changeover switch.

IP65 Rated Protection

The H3 PRO Hybrid is IP65 rated which means that it can be installed either inside or outside. This gives  you the flexibility to choose where to install the system.
