Which Sigenergy systems are compatible?
You can join Amber for Batteries using Amber’s SmartShift technology with the following systems:
- All Sigenergy inverters and batteries which include a 'Sigen Gateway' or 'Sigen Sensor' are compatible with SmartShift.
- You can check whether you have this in the mySigen app, by tapping the 'Device' tab, then scrolling to the 'Sigen Device' section (as per screenshot below).
- If you have solar attached to your Sigenergy inverter and your system is DC-coupled, you will be eligible for ‘load-following curtailment’. We cannot run curtailment on AC-coupled systems.
How do I sign up to Amber for Batteries?
If you haven't already provided the battery details during sign-up for your Amber account, follow these steps via the Amber app:
- Download the Amber app.
- Log into the Amber app using the email and password created on registration.
- Head to the Devices tab at the bottom of the screen.
- Select Sigenergy as your brand.
- Fill in your System ID details in the form. Please do not use your serial number
How to locate your System ID
- Login to the 'mySigen' app
- Tap 'Settings'
- Tap 'System Settings'
- Tap 'About', then long press on the System ID to copy the ID to your clipboard (or send us a screenshot)
What happens after I sign up?
We've published this guide on the Amber for Batteries Enrolment Process if you want to take a deep dive.
After you've signed up to Amber and submitted your battery details via the website or app, we will check that your site is all set up to join the SmartShift program. This includes making sure that you've officially transferred to Amber as your electricity retailer, that you've got a smart meter installed and that your meter is configured to record solar exports. All this has to happen before we can continue with the battery enrolment.
Important: Once you're enrolled to SmartShift, the operational mode shown in the mySigen app will be locked to the VPP mode. To change modes, the Amber team will need to remove your system from SmartShift.
Checklist to avoid delays during enrolment
Ensure the grid feedback maximum rate is set to the correct export limit of your site
Please check the "Export Limitation" value in your "Parameter Settings" in your MySigen app (see screenshot for example of the settings page) and ensure this is not set to 0W and enabled. Determine which situation applies as per the below:
- If your installer has already set the correct import and export limitation value above 0, there is no further action required.
- If your installer has set the value to 0W but disabled the setting, just let us know and we will continue your onboarding without any changes needing to be made.
- If your installer has set the value to 0W and enabled the setting, your installer will need to change the value (in watts) to the appropriate maximum export power for your site.
Ensure you have VPP mode enabled and external control devices are disabled
Your device must be in VPP mode for Amber to be able to successfully connect and send commands to it. If you are in another mode (specifically EMS mode), you must switch out of this mode, otherwise your SmartShift enrollment will be blocked.
You must also disable any external control devices connected to your Sigenergy system.
See this guide for instructions on how to change modes.
Please also note that once your device is onboarded to SmartShift, if you at any time change yourself to any mode other than VPP mode, the SmartShift automation will stop functioning.
Check whether you have Sigenergy's Storm Watch feature enabled
Storm Watch is a Sigenergy feature designed to respond to forecasted storms in your local area. When a severe weather event is forecasted, this feature will charge your battery to 100% and preserve that charge level, in order to provide your household with reserved backup power in the event of a blackout.
This will override any SmartShift commands in the period where Storm Watch has taken control.
Whilst SmartShift and Sigenergy's Storm Watch can both be enabled at the same time, if you notice that your battery is 'stuck' at 100% charge, please check the Storm Watch feature in the mySigen app using the steps below:
- Open the 'mySigen' app
- Tap the 'Settings' tab
- Tap 'Backup Reserve'
Customers who also have a Sigenergy EV charger cannot have the vehicle-to-grid (V2G) feature enabled
If you have a Sigenergy battery and a Sigenergy EV charger, having the vehicle-to-grid (V2G) feature enabled will prevent enrollment in Amber for Batteries.
This is because Sigenergy's vehicle-to-grid (V2G) feature currently requires changing your mode to non-VPP mode, as Sigenergy's VPP APIs do not currently support V2G. Being in VPP mode and having the V2G feature enabled is not currently possible.

What about V2H for cars that have this enabled? Is there any way to do bidirectional to the house and still be enrolled in Amber? Can you switch between them?
Hi Kate,
You might be able to manually run a V2H + V2G event for 30, 60, 90 or 120 minutes — but there are a few things to know:
1. Once you’re enrolled, your system is locked in VPP mode. You can’t exit it, but you can temporarily override it (Hold, Charge, Discharge, or Self-Consumption) through either the Amber or mySigen app.
2. V2X isn’t officially supported in VPP mode. Amber can’t initiate or optimise around it, but in practice you can still trigger V2H + V2G manually via the mySigen app. It works, but Amber can’t “see” it and it has limitations.
3. Mode behaviour matters:
A. Hold Battery: EVDC exports at the set kW rate, house load is deducted, balance goes to or comes from the grid.
B. Self-Consumption: this doesn’t just run your house off the car. It also dumps your house battery to the grid at set maximum inverter output rate until SOC = 0%, then only afterwards starts discharging the EV battery. That’s due to how Amber’s locked-in VPP settings prioritise the house battery.
4. While overrides are running, Amber can’t intervene — control reverts only when the timer ends.
5. Warranty is still a grey area. Carmakers don’t explicitly ban V2X in their docs, but they don’t guarantee it either. They rely on broad exclusions (misuse, non-approved equipment, modifications), so unless your OEM gives written assurance, coverage isn’t certain.
