What is a Sunshine grid tie power inverter?
Sunshine Grid Tie Power Inverter is the world's most technologically advanced inverter for use in utility-interactive applications. This manual details the safe installation and operation of the Sunshine Grid Tie Inverter.
How do different inverters handle ground?
Unfortunately, different inverters can handle ground differently so there can be no simple statement on how they handle it. They all tie the AC-out Equipment Grounding Conductor to the case. Inverters that have an AC in (Such as inverter-Chargers) all tie the AC-in Equipment Grounding Conductor to the case.
Can a power inverter be used with a positive ground system?
The inverter is designed to use with the negative ground electrical system! Don't use it with positive ground electrical systems. The power inverter has a terminal on the rear panel marked " Grounding "or “ ". This is used to connect the chassis of the power inverter to the ground.
What is a code-compliant PV inverter?
In code-compliant PV installations, all non-current-carrying metallic equipment is bonded with low-resistance conductors to provide an alternative path to ground. Ground-fault detection is typically automated by devices within the PV inverter, alerting the technician to the fault’s presence. Locating the fault, however, is often challenging.
