(b) Grounding by using unused grounding hole

The existing grounding holes which have not been used can be used for grounding.

1) Direct the grounding clamp to the mounting hole on the frame. Thread the grounding clamp

and the frame with grounding bolt.

2) Put the toothed gasket into the other side, then tighten and lock the nut. The recommended

torque of locking the nut is 2.0 N.m ~2.2 N.m.

3) Thread the grounding clamp with grounding wire. The materiel and size of grounding wire

should meet the relevant requirements of the national, regional and local rule, law and

standard.

4) Finish the mounting with tightening the binding bolt of the grounding wire.

Fig.6 Grounding method (b)

The modules can be grounded using third party grounding devices so long as they are

certified for grounding modules and the devices are installed according to the manufacturer' s

specified instructions.

6.3 Inverters configuration

When installed in PV systems, Amerisolar modules normally do not need to be connected to

earth and therefore can be operated together with either galvanically isolated (with

transformer) and transformerless inverters. However, if the system is located in a hot, humid

climate and the maximum voltage is greater than 600Vdc, then galvanically isolated inverters

incorporating a transformer are recommended to be used and the negative pole of the array

should be connected to earth.
