Sunny Boy Storage: Your Questions, Our Answers

From Thomas Thierschmidt (guest post) on June 14, 2016 in Category Energy Management with 5 Comments

We are very pleased with the great interest in our new battery inverter Sunny Boy Storage. The inverter, which is compatible with high-voltage batteries such as the Tesla Powerwall, is perfectly suited to the consumption of self-generated solar power — even in the evening. Here, as promised, Product Manager Thomas Thierschmidt answers your most asked questions on availability, prices, scalability and much more.

 

 1. Where can I find technical data, operating manual and certifications?

The datasheet on the Sunny Boy Storage and the product page provide an overview of the technical data and the options the Sunny Boy Storage offers.

You will find installation and wiring instructions in the operating manual.

 

2. In which countries is the Sunny Boy Storage available?

The battery inverter has been available from wholesalers in Germany, Austria and Switzerland since the start of April. It is best to ask your chosen installer for the device directly. The Sunny Boy Storage will be available in Australia, Belgium and the UK in June and in Italy in August. More countries will follow over the course of the year.

 

3. How much does the device cost?

Please ask your wholesaler or a trusted installer for the price. Because of our three-step sales model, we unfortunately cannot help you here.

 

4. Can you receive the energy storage subsidy for the Sunny Boy Storage?

The Sunny Boy Storage meets the requirements for the energy storage subsidy. However, you would have to ask Tesla about the battery’s eligibility.

 

5. Are you planning for the system to be scalable?

Yes, an expansion for two Tesla Powerwalls with two Sunny Boy Storage battery inverters is planned.

 

6. Will there be Sunny Boy Storage versions with more capacity?

No, there is no plan for that. At 2.5 kW, the battery inverter has the optimum capacity for private households. It’s specifically designed for use with stationary storage systems in private households.

 

7. Are other high-voltage batteries planned besides the Tesla Powerwall?

Of course, we also want to be compatible with other high-voltage battery manufacturers. You can find out more about future partnerships at Intersolar. We will then also inform you via this blog.

 

8. Is it possible to charge electric cars like the Nissan Leaf?

The device cannot be used for electric cars, as different standards and protocols have to be applied to that field. However, you can integrate your electric car into the SMA Smart Home with the Sunny Home Manager and charging stations available on the market.

 

9. Is the Sunny Boy Smart Energy compatible with the Tesla Powerwall and the Sunny Boy Storage?

No, they are separate systems that cannot be combined. You can either choose the Sunny Boy Smart Energy with integrated battery or the Sunny Boy Storage for high-voltage batteries such as the Tesla Powerwall or a Sunny Island with low-voltage battery.

 

10. Will the zero export function relevant for Australia be available soon? And will it work with the Sunny Home Manager and the SMA battery inverters Sunny Boy Storage, Sunny Island and Sunny Boy Smart Energy?

This function is already implemented in the Sunny Boy Smart Energy, and the Sunny Boy Storage will also be able to control export at 0 percent. It even provides adjustable target values to guarantee minimum electricity purchase and grid feed-in. Together with the Sunny Home Manager, there will also be a zero export solution.

    Can Sunny Boy Storage be used in a three phase design? I assume it can connect to one phase of a three phase but could I have e.g. three Sunny Boy Storage, one on each phase, with either three batteries or one shared battery (similar to how Sunny Island can be used)? This could be useful if charging an EV with a battery of >50kWh, for which one 2.5kW inverter would be very slow (and one Powerwall would be very small, but that’s another issue).

    Hi,
    a small question related to countries :

    a previous system (Sunny boy smart energy) was not sold in France, worst it’s still stated in the website that the use of this system is forbidden in France.

    Could anybody explain me why ?

    I have asked SMA france by mail but never get any answer.
    Is there any legal issue and if yes what rules/law prohibit such installation ?

    Thank you in advance for any reply

    sunny regards

      Hello Jean-Marie,

      At the time of launch, the regulation didn’t clearly allow the use of a grid-connected storage application (UTE C15712-2). Now that the law has evolved, SMA is evaluating the interest and potential for storage solutions in the French market. Stay tuned for further announcement.

      Kind regards,

      Dalila

    Does the inverter actively manage SOC of the powerwall so it is not above 80%SOC for more than. 4hrs/day as required to maintain 10year warranty on the battery.

    Shouldn’t this inverter be warranted to same or similar 18-20MWh throughput as the power wall vs arbitrary 5 years with string inverters

    Cheers karl
