  • Low weight only 9 kgs
  • Built in Wi-Fi or Ethernet connection for monitoring

FAQs

Can I add an SMA Sunny Boy Storage unit to my existing solar power system?

Yes – the SMA Sunny Boy Storage is compatible with all brands of existing solar inverters.

Why is the charge and discharge rate only 2.5kW?

90% of total power loads in Australian households are less than 2,000 watts therefore a higher discharge rate is not required

Why have SMA chosen to use AC coupled architecture?

AC coupled makes the SMA Sunny Boy Storage unit extremely flexible as it is compatible with all brands of solar inverters

Is AC coupling less efficient than a DC coupled system?

AC coupling is slightly less efficient than DC coupling however the difference is minimal. As you can see from the calculation below the efficiency of the AC coupled systems is 1.5% less than a DC coupled system. In real terms the loss of power is the equivalent of 100watts.
