Gridpay & Solar
Gridpay works alongside your solar system. While Gridpay is active, your zappi or zappi GLO can use available excess solar to charge your car outside your tariff window, before charging from the grid during your off-peak period.
There is nothing extra to set up. Simply plug your car in as normal.
Your EV needs at least 1.4 kW of excess solar to begin charging.
Does Gridpay work with solar?
Yes. Whilst Gridpay is active, your zappi or zappi GLO will charge your car from solar whenever sufficient excess solar is available outside your given tariff window.
zappi
This is the same behaviour as ECO+ mode. Your zappi uses available excess solar when enough power is available.
zappi GLO
This is the same behaviour as Smart Charging mode on zappi GLO.
Just plug in as normal. Your charger will use available excess solar during the day before charging from the grid later during your tariff's off-peak rate.
EVs need a minimum of 1.4 kW excess solar to begin charging.
What if I want to prioritise libbi or eddi first?
If you have libbi or eddi alongside your charger and would rather they use your excess solar first, you can rearrange your device priority order.
For example, you can set the priority order to:
Priority 1
libbi
Uses excess solar first.
Priority 2
eddi
Uses any remaining surplus.
Priority 3
zappi or zappi GLO
Uses any remaining surplus after the other devices.
How to change your device priority order
-
Open the myenergi app home screen.
Find the device icons for your zappi, libbi or eddi.
The home screen showing your connected myenergi devices.
-
Press and hold one of the device icons.
Use a long touch on one of the device icons, for example zappi, libbi or eddi. After a second, the screen will change and you will be able to drag the device icons to change their order.
-
Drag your devices into the required priority positions.
Move whichever device you want to consume excess solar first into the Priority 1 slot. If there is any surplus generation left over, it will be used by device 2, and so on.
Drag the device icons to set the order in which they use surplus power.
Drag one device icon on top of the other. They will then be set to have the same priority.
With the priority order set to libbi, eddi and then zappi or zappi GLO, solar will fill libbi and top up eddi's hot water before any remaining surplus reaches your EV.
What if I only want to charge with solar for a while?
During sunny periods, you may want to skip charging from the grid entirely and only use available solar.
You can do this by changing your Gridpay charging preference in the myenergi app.
-
Open the Gridpay menu.
In the myenergi app, navigate to the Gridpay menu.
-
Set your charging preference to 0 kWh.
This will prevent your zappi or zappi GLO from scheduling any overnight charging during your off-peak window.
Switch your charging preference back to your usual amount, for example 20 kWh, the next day or whenever you would like to resume grid charging.
What if I want to export my solar instead?
If you would rather export your excess solar to the grid instead of using it to charge your EV, there are two options.
Adjust your Export Margin
You can change the Export Margin setting in the myenergi app to prevent zappi and zappi GLO from using your excess solar whilst plugged in.
-
Open the myenergi app settings.
Tap the three lines in the top-left corner of the app to open the menu. Then open the Settings menu at the bottom.
Select Device settings from the Settings menu.
-
Go to Device Settings.
Navigate to:
Device Settings > Advanced > Export Margin
Open Advanced settings for your device.
-
Increase the Export Margin.
Your Export Margin is how much excess solar is guaranteed to be exported before your myenergi products start consuming it.
Setting it to the maximum value of 10 kW works for most users, since this is above the peak export for a typical home setup.

Export Margin is a whole-system setting, not just a setting for your charger. Increasing it will also stop excess solar reaching libbi or eddi if you have them.
For more information, read our guide:
Understanding Export Margin and Export Threshold Settings on myenergi DevicesLeave your EV unplugged during the day
If you would rather not adjust your system settings, we recommend simply leaving your EV unplugged during the day.
Plug your car in after sunset, ready for your off-peak charging window.
This avoids changing your Export Margin settings. Your car will be plugged in ready for its scheduled off-peak charge.
Frequently asked questions
Will Gridpay charge my car using solar automatically?
Yes. Whilst Gridpay is active, your zappi or zappi GLO will use available excess solar outside your tariff window. Simply plug in as normal.
How much excess solar does my EV need to start charging?
Your EV needs a minimum of 1.4 kW excess solar to begin charging.
Can I make libbi or eddi use solar before my EV?
Yes. Change your device priority order in the myenergi app. You can set libbi first, eddi second and zappi or zappi GLO last.
Can I temporarily stop overnight grid charging?
Yes. Open the Gridpay menu in the myenergi app and set your charging preference to 0 kWh. Remember to change it back to your usual amount when you want to resume scheduled grid charging.
Does changing Export Margin affect my other myenergi devices?
Yes. Export Margin is a whole-system setting. Increasing it will also stop excess solar reaching libbi or eddi if you have them.
Can I export solar without changing Export Margin?
Yes. You can leave your EV unplugged during the day and plug it in after sunset, ready for your off-peak window.
