Example of Installation of 1KW grid tie power system
In order to explain the installing operation, we assume that there is a house that the usual electricity consumption is about 5KWH per day, and the real irradiation time is about 5 hours.
1, Considering the total capacity of the grid tie power system that you need.
As we stated at Step1, we can get a result that a 1kW Sunshine Grid Tie Power System is
suitable for this house, so we will establish a 1KW gird tie power system step by step, we
also assume that we will install the system in the house where the utility grid is 230V/50Hz.
2, Choosing applicables Solar Panels.
Because the most popular solar panels are 240Wp~250Wp poly panels with 60 PCS solar
cells, so choosing this kind type panels will be more economical. The system is 1KW power
system, so we should use 4 PCS 240Wp to 250Wp solar panels.
Most of this kind type solar panels have similar specification shown below.
Module Efficiency:14.8% Pmax:245W
so use 4 PCS of this type panels, we can get total power:
TPmax = 245Wp×4 = 980Wp
from these solar panels, it is suitable for 1KW SUN-1000G model inverter.
Notes: The Pmax specification of solar panel is under STC, the actual power is variational
according to the irradiation on the panel and the temperature surroundings. The real output
power can't reach Pmax at most time in whole day.
3,Selecting Accessory for Grid Tie Power System installation.
Because we should connect 4 PCS solar panels to Sunshine Grid Tie Inverter, so some
connectors are necessary. Consider of the Voc, Vmp and Isc, we choose some MC4
connectors and some connectors for parallel connecting.
For the choice of DC cables, we should consider about the connecting method of solar panels,
there are two methods can be choosed.
Method 1: Connecting the 4 panels in parallel, so the maximum DC current will be
TImp = TPmax/TVmp = 980W/29.4V = 33.3A or
TImp = Imp × 4 = 8.34A × 4 = 33.3A
According to the Table 2, AWG6 Cables should be choosed.
Method 2:Connecting 2 panels in serial consist as a pair, so 4 panels can be gotten 2 pairs,
TImp = TPmax/TVmp = 980W/58.8V = 16.7A or
TImp = Imp × 2 = 8.34A × 2 = 16.7A
So according to the Table 2, AWG9 cables should be choosed.
Because the DC cables will be more expensive if the diameter is big, considering about this
matter, the method that can use smaller diameter cables will be a good choice.
4, Selecting correct model of Sunshine Grid Power Inverter.
Because maybe there will be several methods of connecting solar panels to Sunshine Grid
Tie Inverter, different connecting method maybe should use different model inverter. In this
case, there are two connecting methods.
With method 1, because all panels are connected in parallel, so we can know that the
TVoc(total Voc of the solar panels) will be same as Voc of one panel, and the TVmp also
is same as Vmp of one panel. So we can get the specifications of the solar panels array
with solar panels connected each other.
From these specification, we should to use SUN-1000G-M-E. This is because, the DC input
voltage range of this model is 22V to 60V, so the TVoc and TVmp is in the DC input voltage
With method 2, we also can get the specifications of the solar panels array.
From these specifications, we should to use SUN-1000G-H-E. This is because, the DC
input voltage range of this model is 45V to 90V, so the TVoc and TVmp is in the DC input
The two connecting method diagrams are shown in Fig.4 and Fig.5 below.
Comparing the connected method in Fig.4 and Fig5, we can see that method 2 is the good
choice, because with method 1, the DC cables is more thick, so it is more expensive, and
three pairs of connectors for parallel connecting plus three pairs of MC4 connectors should
But with method 2, the DC cables is thin, and just a pair of connectors for parallel connecting
and a pair of MC4 connector should be used.
Installing Sunshine Grid Tie Power System to Three Phases Utility Grid.
When the Capacity of Gird Tie Power System is larger, intall all the power system to one
phase of the utility grid is not reasonable, maybe this will cause unbanlance of the three
phase of the utility grid.
In this section, we will explain how to install Sunshine Power System to three phases utility
grid seperately in order to balance the fed power.
