First connect the positive DC wire from the PV module to the negatively marked DC connector (female
socket) of the Micro-inverter. Then connect the negative DC wire from the PV module to the positively
marked DC connector (male socket) of the Micro-inverter. Repeat for all remaining PV modules using
one Micro-inverter for each module.
Step 6-Complete the Meikai Micro-inverter Installation Map
The Installation Map is a diagram of the physical location of each micro-inverter in your PV installation.
You can use the blank map in the Appendix to record micro-inverter placement for your system. When
your map is complete, send it to Meikai as described below. Meikai then uses this information to provide
you with detailed information about the performance of your PV system and to allow you to see a
graphic representation of your PV system on the web-based monitoring and analysis. Feel free to
provide your own layout if a larger or more intricate installation map is required.
