Growatt solar battery scheduling & setup

This guide explains how to configure your Growatt hybrid inverter and battery with a compatible battery system to discharge between 5:30pm and 7:30pm using Time of Use (TOU) mode in the ShinePhone 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:

Growatt MIN-XH
Growatt MOD-XH
Growatt SPH
Paired with compatible Growatt batteries (e.g. Growatt ARK Battery System)
Using the ShinePhone app (iOS/Android) or web portal

Ensure:

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

Step 2 –

Set work mode to TOU (Time of Use)

Open ShinePhone
Select your inverter
Go to Settings
Navigate to Work Mode / Battery Mode
Select Time of Use (TOU) mode.

Why TOU?

TOU mode allows you to schedule when your battery charges or discharges.
If your inverter is set to Self Consumption mode, it will prioritise powering your home and may not export energy during the Happy Hour window.

Step 3 –

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

In TOU mode, locate the Battery Schedule or Discharge Period settings.

Add a new time period:

Start: 17:30
End: 19:30

Set this period as 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 your battery has energy available:

Navigate to Battery Settings
Locate Minimum 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 miss part of the 5:30–7:30pm 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
Export limit matches your DNSP approval

Commonly:

5 kW export limit for single-phase systems, but this varies by region and DNSP.

If these settings are locked, contact your installer.

Step 6-
Verify during Happy Hour

Between 5:30pm–7:30pm:

Check the ShinePhone dashboard and look for:

Battery discharging
Grid export visible
Export power greater than 0 kW

If the battery is discharging but export remains 0 kW:

Your home load is using all battery energy
Or grid export is restricted by system settings

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.
