Understanding sonnenConnect

How does sonnenConnect work? 

When you sign up to sonnenConnect, you give sonnen the right to remotely operate the battery.  sonnen is able to operate the battery to stabilise the local grid. You don't need to do anything.

Is there a agreement for this offer?

Yes, there is a contract between the sonnenBatterie operator (you the sonnenBatterie owner) and sonnen Australia Pty Ltd. Please click here to see the terms.

When will I receive payments for my participation in sonnenConnect?

Funds will be deposited in your bank account at the end of each month.

Is my daily rate fixed and how long is it guaranteed? 

Rates and terms are detailed in product term sheets.

Is the payment rate different for different battery sizes?


Is there any minimum battery size for this offer?

Yes, 4 kWh of usable capacity.

Can I have both sonnenConnect and sonnenFlat (or another VPP)?

No. sonnenFlat customers are already participating in our VPP.  One can be in either sonnenFlat or sonnenConnect, but not both. This also applies to VPPs outside of sonnen.

Will I get paid my feed-in-tariff from my retailer for energy sent back to the grid?

Any exports to the grid will continue to appear as feed-in on your electricity bill. Your sonnenConnect agreement is independent of your electricity retail contract.

Do I need a smart meter?

No, there are no grid meter requirements for sonnenConnect.

Are there exit fees?

No. You may exit at any time, we just need 2 weeks notice. No exit fees apply.


Will my battery be accessed during a blackout event? 

No.  Failure of supply in the local grid removes the battery from the VPP.  VPP is only active on a live local grid.

Will sonnenConnect impact my battery reserve in any way?

sonnen does not access the energy reserved by the sonnenBatterie.

How much energy will you use from my battery?

This will depend on the needs of the grid services. You will receive a report on a regular base detailing the amount of energy used.

Will my participation in sonnenConnect affect my sonnenBatterie warranty?

No. sonnenBatteries are warranted to 10,000 cycles over 10 years, or 2.7 full cycles per day on average.  Participation in sonnenConnect will not affect the sonnenBatterie warranty.
