SMA Sunnyboy Inverters
The
Sunny Boy is the most successful solar inverter for grid connected
PV-plants. There are plenty of good reasons for this. SMA has
successfully been developing and manufacturing systems for energy
conversion in railway applications and for industry for over two
decades. This outstanding know-how is the basis for the Sunny Boy
inverter.

Inverter Size Selection:
The inverter size is selected based on the power and voltage output of
the panel array. The power output of the array is the
system size and is calculated as follows:
(system size) = (number of panels) x (power per panel)
The following could be used as a general guideline for inverter
selection based on system size:
|
System size |
2.0
- 3.0 kw |
3.0
- 3.7 kw |
3.7 - 5.0 kw |
5.0 - 6.2 kw |
6.2 - 7.5 kw |
7.5 - 8.7 kw |

The calculation of the voltage output of the system is a little
tricky, becuase the voltage output of each panel increases with
decreasing temperature. The max voltage output depends factors
like lowest temperature observed in the region, voltage temp
coefficient, and no. of panels in series. SMA has a very useful
tool that does all those calculations for you. Just click on the
