SUNGROW BATTERY SCHEDULING
Lock in a peak export rate and save at other times by charging your battery when wholesale prices are low.
Sungrow solar battery scheduling & setup
This guide explains how to set your Sungrow hybrid inverter and compatible Sungrow battery to discharge to the grid between 5:30pm and 9:30pm using a Time of Use period in the iSolarCloud app, so you make the most of Flow Power’s Battery Happy Hour.
This setup is required if you’re participating in Flow Power’s Battery Happy Hour Electricity Plan.
Why choose Happy Hour?
- Keep full control of your solar and battery and earn a 30-35c/kWh feed-in rate between 5:30-9:30pm, every day.
- Our dynamic pricing rewards you for using energy when it’s cheaper and more renewable.
- Your home’s energy use is matched with 100% GreenPower from one of our renewable projects in your state.
- Better manage their energy use with the help of smart insights via the Flow Power app.
How to setup your battery
Step 1 –
Confirm your inverter & app access
You need a Sungrow SH-series hybrid inverter with a compatible Sungrow battery. Download the iSolarCloud app (iOS or Android) or use the web portal, and log in with your owner account.
Step 2 –
Open Energy Management Parameters
Log into your plant in iSolarCloud and tap the three dashes at the top right. Select “Device”, then tap “Energy Storage System”. Slide the tab at the top to the left, then select “Settings”, then “Energy Management Parameters”.
Step 3 –
Create the 5:30pm–9:30pm discharge window
Under the Time of Use periods, set a discharge period from 17:30 to 21:30. (You can set up to two Time of Use periods.) This is what pushes the battery to discharge during Happy Hour.
Step 4 –
(Optional) charge when energy is cheap
If you also want to top the battery up from the grid at cheaper times, use the “Forced Charging” section just below and set a charge window and target charge SOC%. Note: the battery cannot discharge during a forced charge period, so keep it clear of Happy Hour.
Step 5-
Check your minimum / reserved State of Charge
Make sure your reserved (minimum) State of Charge isn’t set so high that the battery stops discharging early. Around 10 to 20% leaves enough to discharge through the whole window.
Step 6-
Confirm export is enabled
Make sure export is enabled and within your DNSP export limit (not set to zero export). Battery-to-grid export will not work if you are signed up to a VPP.
Step 7 –
Apply Settings and verify
Tap “Apply Settings” to save. Between 5:30 and 9:30pm, open the iSolarCloud dashboard – you should see the battery discharging and power exporting to the grid.
Do I control my own exports?
Yes. You keep full control of your solar and battery system at all times.
Flow Power doesn’t remotely control your inverter or battery. Instead, we give you price signals and a clear export 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.
