At this point, be sure to connect the L wires from each set to L, and the N wires to N.
In other words, for the input L and N, connect L to L in parallel, and N to N in parallel.
The same applies to the output UVW:
U is connected in parallel with U, V is connected in parallel with V, and W is connected in parallel with W.
This configuration achieves double the power output.

This is very simple.
You just need to pay attention to the wiring order.
And the size of the input power cable.
Specifically, when connecting two CHP units in parallel, the input power cable must be twice the size.
In other words, the input power cable must be at least 30 square millimeters in cross-sectional area.
Then split this cable into two sets of wires and connect them to the L and N terminals of the two inverters, respectively.
