Starting DIY from small grid tie power system.
If you never have experience of installing grid tie power system before, you can start DIY(do
it by yourself) from small grid tie power system.
, this is a small power
inverter that the rated output power is 225W, and the peak power can reach 250W, so you
can establish a small capacity grid tie power system with this model inverter and a big solar
panel or two smaller solar panels, the total Pmax of solar panels should be less than 250Wp.
it’s very easy to install this kind small system, just need DC cables and few connectors to
connect the system. For example, you can choose a 245Wp solar panel or two 120Wp solar
For example, installing a 3KW grid tie power system to three phase utility grid.
The diagram is shown in Fig. 8, we seperate 3KW power sytem to three power system units,
every unit has 1KW power. Connecting every system unit to different phase, this can
balance all grid tie power to three phases of the utility grid.
Fllow this way, you can install more large grid tie power system to three phases, just
seperate the whole power system to three equal power system units.
