Fox ESS solar battery scheduling & setup

This guide explains how to configure your FOX ESS hybrid inverter and compatible FOX ESS battery to discharge between 5:30pm and 7:30pm using Time of Use (TOU) mode in the FOX ESS Cloud app.

This setup is required if you’re participating in Flow Power’s Happy Hour program.

How to setup your battery

Step 1 –
Confirm your inverter & app access

This guide applies to:

FOX ESS H1 Hybrid Inverter
FOX ESS H3 Hybrid Inverter

Paired with FOX ESS high-voltage batteries (e.g. ECS / HV battery systems)
Using the FOX ESS Cloud App (iOS/Android) or web portal

Ensure:

Your inverter is online
You have owner-level login access
Your battery shows available capacity

Step 2 –

Set work mode to TOU (Time of Use)

Open FOX ESS Cloud
Select your inverter
Go to Settings
Navigate to Work Mode (or Energy Management Mode)
Select Time of Use (TOU)

Why TOU?

TOU mode allows you to schedule specific charge and discharge periods.
If your inverter is set to Self-Use mode, it will prioritise powering your home and may not export during the Happy Hour window.

Step 3 –

Create the 5:30pm–7:30pm discharge window

In TOU mode, locate the Discharge Schedule section.

Add a new time period:

Start: 17:30
End: 19:30

Set this period to Discharge.

Save settings.

This instructs the battery to discharge during the Happy Hour window.

Step 4 –

Set Minimum State of Charge (Min SOC)

To ensure available energy:

Navigate to Battery Settings
Locate Min SOC (Minimum SOC or Reserve SOC)
Set to 10–20% (typical recommendation)

If Min SOC is set too high (e.g. 40–50%), your battery may stop discharging early and not fully participate in the export window.

Step 5-

Confirm export settings

Even if your battery discharges, export may be blocked if:

Export Control is disabled
Export limit is set to 0 kW
DNSP export cap is lower than inverter output
Installer has locked export permissions

Check:

Go to Advanced Settings
Confirm Export Control = Enabled
Confirm export limit matches your DNSP approval (commonly 5 kW single phase, varies by region)

If these settings are locked, contact your installer.

Step 6-
Verify during Happy Hour

Between 5:30pm–7:30pm:

Open the mySigen App dashboard.

Look for:

Battery discharging
Grid export shown as negative grid consumption
Export power greater than 0 kW

If battery is discharging but grid export is 0:

Your home load is absorbing all energy
Or export is restricted

Do I control my own exports?

Yes. You keep full control of your solar and battery system at all times.

Flow Home doesn’t remotely control your inverter or battery. Instead, we give you price signals and a clear Happy Hour window, and you decide how to respond.

If you have a battery or smart inverter, you (or your installer) can set it up so you charge when energy is cheaper and export more during Happy Hour, but all those settings remain in your hands.
