INVERTER AND SOLAR PANELS EARTH GROUNDING

The CirPower Hyb is a transformerless inverter, without galvanic isolation

between grid and solar panels� Therefore, solar panel active conductors

(PV+, PV-) must not be connected to earth, and must be floating.

Take into account local regulations regarding solar panel protective grounding.

In the

CirPower Hyb

inverter, all metal parts are electrically connected to Earth, so it must be

ensured that the Earth is properly connected to the grid connector (Line, Neutral and Earth).

To ensure the safety of persons, the Earth conductor must be connected to the

installation Earth.

5.8.- RS-485 CONNECTION

Figure 20: RS-485 connection�

To get access to the RS-485 connector, follow these steps:

1�-

Unplug the AC grid connector.

2�-

Ensure the DC switch is off.

3�-

Unplug the solar panel connectors. Wait 15 minutes until DC bus link is completely dis-

char-ged.

4�-

Unscrew completely the front cover screws, using a 3mm Allen key (ISO 2936)
