The inverter diagram depicts a typical AC installation. The main panel has an output breaker for the non-inverter loads. It is
used to power the high power loads that are beyond the inverters capacity such as a water heater or an electric stove. The
inverter AC input must be protected by a circuit breaker rated at 50A or less, and the cable cross section must be sized
accordingly (10AWG for 30A, 6AWG for 50A). Make all connections using proper crimp-on connectors (do not use twist on
connectors).
A Residual Current Device (RCD) type circuit breaker rated to support the expected load must be included in series with the
output, and cable cross-section must be sized accordingly. This breaker should be as close to the inverter as possible. If this
breaker is not of the RCD type, GFCI receptacles must be used at all AC outlets.
The inverter is provided with a ground relay that automatically connects the neutral output to the chassis if no external AC
supply is available. In an RV installation, the inverter chassis must be connected to the vehicle chassis ground (via the
negative distribution bus). The chassis grounding conductor must be not less than one size smaller than the DC positive
conductor and have a capacity such that the DC positive fuse has an amperage rating not greater than 135% of the current
rating of this grounding wire.
When using an inverter sub panel, the inverter neutral cables must return to the inverter sub panel and not the main
AC panel.
A warning label should be installed at the main AC panel to indicate that there is an inverter in the system.
