Sunny Boy Storage: The Quick and Easy Way to More Independence

(Update 5/22/2018) Starting in June, the powerful SMA battery inverter Sunny Boy Storage 3.7/5.0/6.0 for private homes will be commercially available. In this post, you will learn how to install and commission the Sunny Boy Storage in a few steps and what makes the device so special.

 

With its three power classes 3.7 kW, 5.0 kW and 6.0 kW, the Sunny Boy Storage is following the trend toward higher power and battery capacities for home storage systems. Solar Academy trainer Jan Rössler proves in the tech tip that the Sunny Boy Storage can be easily installed by one person. He also offers helpful tips on how to do it even faster.

In the screencast, he shows how fast you can connect the device to the utility grid after successful installation. The Sunny Boy Storage can be commissioned quickly and easily via a smartphone, tablet or PC in a few steps and thanks to an integrated web interface.

Refueling and heating for free

What actually sets the big brother apart from Sunny Boy Storage 2.5? It is mainly the multi-string battery connection that makes this battery inverter unique (possible via the automatic firmware update starting in the fall 2018). With three battery connections in total, the Sunny Boy Storage grows with the individual needs of its users. Maybe in the near future, you want to charge your electric vehicle in a climate-neutral manner and for free with electricity from your own PV system. Or you want to supply a heat pump with self-generated solar power. With this, high electricity bills are a thing of the past. If you start off with a small self-consumption system today, you can easily expand the storage capacity tomorrow. Further high-voltage batteries (independent of the manufacturer) can be added anytime.

 

A reliable supply at all times

And then there is the integrated Secure Power Supply function. In case the utility grid fails, PV system operators can use it to continue supplying individual loads manually with solar power. Thanks to the optional battery-backup function, you do not even need the utility grid: In the event of a grid failure, the battery inverter then continues to automatically supply the entire household with clean solar power. Especially in markets with an unreliable utility grid, the Sunny Boy Storage is a real and, above all, sustainable alternative.

 

Ease and comfort with SMA Smart Connected

The Sunny Boy Storage 3.7/5.0/6.0 is the first battery inverter equipped with the SMA Smart Connected service package. This means that PV system operators and installers benefit from automatic and free inverter monitoring by SMA. As a result, nothing will get in the way of high self-consumption.

    Installed Sunny Boy Storage with a 20Kw SMA Inverter and an LG Chem 9.8kWh battery in November 2017.
    Had a grid outage in March but was not at home to experience the back up battery.
    Had another grid outage last week, was home, there was no back up despite the battery being fully charged?
    Thought this was a fault, so called my PV installer, they advised the next day that this was not a standard function of the Sunny Boy Storage!
    Had I know this, I would not have installed SMA equipment, as continuity of supply was a mandatory condition for the PV install, would have gone with Solar Edge!
    So 2 questions:-
    1. Can an add on be achieved to allow the battery to back house power during grid outage?
    2. Can the current Sunny Boy Storage be upgraded to the new version with integrated Secure Power Supply at minimal cost?

      Hello Stephen,

      The studies undertaken in the preliminary stages of developing the backup system for the Sunny Boy Storage 2.5 have shown that offering the backup system would, in all probability, not lead to customer satisfaction. SMA has been unable to develop and offer an optional Backup Box, which is necessary for safe disconnection and switchover in the event of a grid failure, at an economically viable price (in relation to the system costs without Backup Box).
      A further reason is the relatively low amount of power that would be available to supply the connected loads in backup operation. The system would have to be disconnected immediately due to an overcurrent if loads with high startup currents, such as microwave ovens and vacuum cleaners, but also larger halogen spotlights (500 W), are switched on.
      We deeply regret that SMA has falsely raised expectations, and would like to offer our sincere apologies. SMA is, however, committed to only providing its customers with products that are expedient, economical and of a high quality, in order to be able to ensure the satisfaction of its customers with the purchased products, also in the long-term.

      Sunny regards,
      Carolyn

    Hi,
    So the statement above “In the event of a grid failure, the battery inverter then continues to automatically supply the entire household with clean solar power.” is this true or just a marketing ploy as the previous comment states. Can it in the event of a grid failure supply power?

      Hi Mo,
      Yes, in the event of a grid failure, the Sunny Boy Storage can supply the entire household with solar energy. It´s no marketing ploy. You´ll even have two options for supplying your household which may depend on the quality of the public grid or your striving to independency: a.) use the integrated Secure Power Supply to provide electricity to individual loads manually from the battery OR b.) use the optional automatic transfer switch for full power supply to the home from the battery and PV system. The power in the battery-backup operation of up to 8 kW is sufficient for all standard loads.
      Kind regards, Anke

    Hello,
    I am now completely puzzled whether Sunny Boy Storage can or cannot act as a safety backup in case of a grid failure. Carolyn’s post states: “SMA has been unable to develop and offer an optional Backup Box, which is necessary for safe disconnection and switchover in the event of a grid failure, at an economically viable price (in relation to the system costs without Backup Box)” Now, how should I understand that post?

    Thanks in advance
    Peter

      Hello Peter,

      hopefully this will clarify your request:

      Departs cw 23 there will be the Sunny Boy Storage in more engine-power classes. Those are the new Sunny Boy Storages:
      – SBS3.7
      – SBS5.0
      – SBS6.0
      Those battery-inverter are SPS and backup compatible.

      The SBS2.5 neither have a SPS nor a backup function.

      Sunny regards,
      Carolyn

    Hello Carolyn,

    Thanks for your helpful reply above.
    I’ve been searching for the backup device detail of SBS 6.0 through website and manuals but couldn’t find any, just stated that to be done by outside supplier.
    Could you please give more info on the issue – how and when to get that backup device, since it’s really important for the project we are working on.

    Kind regards,
