As indicated in the diagram below, the array GEC can be installed either in series
or in parallel.
Micro Inverter Layout
Using the installation map template in this manual, draw out the layout of the
array and have it readily available during the installation of the micro inverters to
record micro inverter location.
Draw the layout of the solar panels in the installation map template like the
sample image shown below. When a micro inverter is fastened in its position,
then the secondary serial number sticker on the DC side can be peeled off the
micro inverter and adhered to the installation map template where the actual
position on the roof would correspond to the same panel on the layout drawing.
Note: Tracking micro inverter location by serial number is key for data monitoring
and warranty servicing.
Surge Protection
The micro inverters have integral surge protection built-in; however, if the surge
has sufficient energy, the built-in protection in the device would be exceeded and
the device could potentially be damaged. Therefore, external surge protection
MUST be installed as part of any solar installation.
Please refer to the “Surge Suppression” section on pages 2 and 3 on
specifications for appropriate surge protection.
