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
be used.
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 larger capacity of grid tie power system.
Sometimes, maybe you are willing to install larger capacity of grid tie inverter in your house,
this is also very easy to operate. For example, you want to install 2KW grid tie power system,
you can install two 1KW grid tie power systems as shown in Fig.5, two AC output cables
should be all connected to the AC outlet of the utility grid with the plugs.
The diagram of the 2KW grid tie system with two 1KW sytem are shown in Fig. 6, we call this
kind system as “Stackable System”.
