FoxESS HEMS

About FoxESS

Fox ESS is a Chinese inverter and storage maker founded in 2019 and headquartered in Wenzhou. Homes typically have the single-phase H1/AC1 (2.5–6 kW) or KH (7–10.5 kW) hybrid inverters or the three-phase H3 Smart (5–15 kW), with EP, EQ or ECS batteries. Its monitoring app is FoxCloud 2.0.

What is a Home Energy Management System?

A HEMS (Home Energy Management System) helps you get the most out of your solar installation. It monitors your PV production in real-time and automatically steers connected devices like EV chargers, heat pumps, and smart plugs to maximize self-consumption.

With Zerofy as your FoxESS HEMS, you can:

• Monitor real-time solar production and home consumption
• Optimize self-consumption through intelligent device control
• Save on electricity bills with dynamic tariff integration
• Track your energy independence and CO₂ savings

Key Features

What FoxESS offers on its own

Before connecting FoxESS to Zerofy, it helps to know what FoxESS offers on its own:

• EV charging: FoxESS sells its own AC wallboxes. Paired with a FoxESS inverter and meter, FoxCloud 2.0 offers PV Linkage with a Green Mode (solar only) and an Economic Mode (solar first, grid keeps it at 6 A when solar is short), adjusting the charging current between 6 and 32 A.
• Heating: FoxESS has its own R290 heat pumps (HP Series monobloc, HP BOX hydro module), controlled in FoxCloud 2.0, which lists a solar heating feature. The three-phase H3 Pro can switch an SG Ready heat pump through its dry contacts when feed-in exceeds a set start power.

How It Works

1. Connect your FoxESS system – Zerofy connects to the FoxESS cloud: you log in with your FoxESS Cloud account and authorize access on FoxESS’s own screen.
2. Add your devices – Connect your EV, charger, heat pump, or smart plugs
3. Enable Autopilot – Let Zerofy automatically optimize for solar self-consumption
4. Track your savings – Monitor your energy independence and cost savings

Good to know: Use the owner account of the device. Installer and agent accounts don’t own the devices, so FoxESS shows “No Devices” and the connection fails.
