AGL VPP Sigenergy battery control

PAF — Wed, 29 Jul 2026 02:05:57 GMT

Does the AGL BYOB integration for Sigenergy use Virtual Battery Allocation, or does it temporarily override the inverter’s operating mode during a VPP event?

Hi @PAF

Great question! AGL’s VPP integration does not use Virtual Battery Allocation, This is separate to how AGL's VPP operates.

When your battery is participating in the AGL VPP, we may temporarily control the battery during VPP events to help support the grid. Outside of these events, your battery continues to operate as normal based on your chosen settings.

If you're using Sigenergy's Virtual Battery Allocation feature, we recommend checking with Sigenergy on how the feature works and whether it suits your preferred battery setup and energy goals. 😊

I have a Sigenergy battery system with a 20kW TP inverter. Will I still be able to control when my battery automatically imports and exports to grid after joining the VPP (e.g. using the Sigenergy app or Home Assistant)?

Hi @saturnv5

Yes! When you join the VPP, we only take control of your battery during VPP dispatch events. At all other times, you'll retain control of your battery settings and can manage charging, discharging, imports, and exports as you normally would using the Sigenergy app.

So if it was in Sigen AI mode before a VPP event, AGL takeover when an event occurs, is it returned to Sigen AI mode after the VPP event occurs? I just want to know whether I have to intervene or not.

Hi @PAF

Yes, that's correct. If your battery is in Sigen AI mode before a VPP event, AGL will temporarily take control of the battery for the duration of the event. Once the event has finished, control is automatically returned to your previous settings, including Sigen AI mode if that was enabled beforehand.

There is no action required from you.

Hi,

I would like to sign up my Sigenergy system to the AGL VPP with the Battery Rewards Plan and this issue is key. I have spoken to several AGL VPP folk recently and have been told there were still issues with this. Has this now been fully resolved? If I sign up today, will it work as you have outlined here?

Hi PAF,

Did you have success with this? I want to do the same thing.

Hello

I am confused by this. As of yesterday, my Sigenergy system has a new Operational Mode called "VPP Scehduling-evergen". If I try to change to a different mode I can't. Instead there is a message "Please deactivate the VPP service before switching to another mode".

I was told when I signed up to the VPP that I would still be able to choose when to charge and discharge the battery, however, the VPP would take priority during VPP events. I am perfectly fine with that.

But what seems to be happening now is that I am stuck on my last Time Based Control settings without anyway to change those settings.

This is important because I am currently on the Three For Free plan. I charge my battery between 10 AM and 1 PM, and then I discharge the battery between 5 PM and 9 PM.

I am planning on moving to the Battery Rewards plan in spring, and I still want to be able to set a discharge between 5 PM and 9 PM.

I accept that the VPP may over ride when I want to charge and discharge, but I still want the flexibility to set when the battery charges and discharges.

Hi @ShowsOn

Thanks for reaching out.

What you're seeing is expected as part of the Sigenergy onboarding process. The "VPP Scheduling - Evergen" mode indicates that your system has been connected to the AGL Virtual Power Plant and is currently being managed through the VPP integration.

As outlined in the email sent over the past couple of days, we're in the process of transitioning Sigenergy customers to Sigen AI Mode. Once this transition is complete, you'll regain the ability to manage your battery's operating preferences while still participating in the VPP. The VPP will continue to take priority during VPP events, but you'll be able to configure your preferred charging and discharging behaviour outside of those events.

At the moment, your system is still in the onboarding stage, which is why you're unable to switch operating modes or adjust the charge/discharge settings directly in the mySigen app.

As part of the onboarding process, your battery's operating mode will automatically change from VPP Scheduling - Evergen to Self Consumption. Once you see this change reflected in the mySigen app, please follow the instructions provided in the Customer Guide - Sigenergy Operating System Configuration that was included in the email to change your operating mode to Sigen AI Mode. This will allow you to manage your preferred charging and discharging behaviour while continuing to participate in the AGL Virtual Power Plant, with the VPP only taking priority during VPP events.

We understand the importance of maintaining your preferred charging and discharging schedule, particularly for plans such as Three Hours Free and Battery Rewards, and we're working through this transition as quickly as possible.

Please refer to the email for the full instructions and next steps.

Thanks!

Thank you for the follow up.

I saw the app changed from Evergen to Self Consumption this afternoon.. I have now set it to Sigenergy AI.

Does this mean I am now part of the VPP?

I have only been an AGL customer for 2 weeks as of today, and the AGL app still isn;t showing me any power usage data. The app says Electricty usage pending.

Only in the last 48 hours has the mode changed to VPP as AGL test the system. Earlier tonight, it changed to Self Consumption. I am waiting for the official email from AGL so that I can return it to Sigen AI mode (Balanced).
One thing I was not aware of was that whilst the testing was being undertaken, that I lost the export revenue during that time ( 2 nights revenue loss - hidden initial cost). A minor revenue loss, but I didn’t know that was going to happen. Also, after VPP mode, it went to Self Consumption, exactly as the AGL email said. But that means that I do have to change it to Sigen AI mode (balanced) - it does not automatically do that. Whilst it’s not an official VPP event, it’s something to watch out for. Hope this helps.

Yes I monitored mine and did a manual override to ensure I exported between 5 PM and 9 PM last night.

PAF — Sun, 30 Aug 2026 11:33:23 GMT

I am leaving mine until I get the “official” email. Three days now - hoping the email happens tomorrow.

Re: AGL VPP Sigenergy battery control

PAF — Sun, 30 Aug 2026 21:45:26 GMT

For the VPP test, the mode went from Sigen AI to VPP (for a couple of days) then to Self Consumption. I have now changed it to Sigen AI mode, and expect that the battery operation is back to normal. I am now on Profit Maximiser, to maximise the export during 5-9pm.
The only thing I don’t know is that when a VPP event occurs and concludes, will it go to Self Consumption or Sigen AI mode thereafter? I have been told yes, but time will tell.
