17 Power Tower - User manual - English
Grounding of the Power Tower should reflect local electrical codes and installation location and
application requirements. The following should be used as a general rule but should be confirmed
by local electrical codes.
4.1. Grounding
4.1.1. When Earth Ground is Available
When a proper ground to earth is available, the Power Tower grounding point should be tied to
earth. In this installation, the neutral (white) should be separate from the ground (green) wire.
4.1.2. When No Earth Ground is Available
Ground and neutral wire should be bound and should be connected to the negative battery
bus. To do so, connect the grounding point on the Power Tower to the negative terminal of the
battery. Connect the output neutral AC wire to the grounding point or the negative terminal. The
resulting circuit should be equivalent to the following. A separate GFCI will need to be installed
on the output in the circuit breaker panel.

The Power Tower is configured for use with a plug-and-play solar panel.
