Grounding
DC Side Connection
The Renogy Pure Sine Wave inverters come equipped with a grounding lug to appropriately
ground to earth or to another designated ground (for example, a metal frame of an RV). The
connections to ground must be tight and against bare metal. Whether using the inverter in a
mobile application, such as an RV, or in a building, grounding is highly recommended. The
recommended wire size for grounding is 10 AWG insulated copper strand wire. For more
information regarding grounding, users and/or installers must consult with the Local and
National Electric Codes (NEC) for more specific grounding regulations and suggestions as
they can change per scenario.
The Renogy Pure Sine Wave Inverters are suitable for 12V battery bank
systems ONLY. Not following the minimum DC requirement will cause
irreversible damage to the unit.
WARNING
CAUTION
Be careful of the positive and negative poles. Reversing the poles might
cause permanent damage to the inverter. It will surely blow the internal fuse.
NOTE
Damage to the Renogy inverters due to reverse polarity is NOT covered by
warranty.
NOTE
The input terminals of the inverters have large capacitors connected to them.
Once a positive and negative wire are connected to the terminals, it will
complete the circuit, and commence drawing a heavy current momentarily. As
a result, there may be a sparking occurring even if the inverter is in the off
position. To minimize sparking, it is recommended that the user have the
appropriate size wire feeding into the inverters and/or install an external fuse
leading into the inverter.
