If you are installing the IC Series Inverter/Charger on a boat there are some specific guidelines/standards to follow. The Inverter/Charger must be installed adhering to the standards of the ABYC (American Boat and Yacht Council). Some guidelines are outlined below but these notes do not replace the full guidelines detailed in the ABYC standard. Always install the Inverter/Charger using the ABYC standard as the primary reference.
Safe AC and DC Ground Connection
As detailed in the last section when the AC power source is being supplied by shore power (marina) the onboard neutral must be connected to the safety ground on the dock. This feature is automatically taken care of by the Inverter/Charger. When the AC power source is being supplied by the Inverter (battery bank) the onboard neutral must be connected to the common boat ground. The DC ground terminal must also be connected to the common boat ground. This ensures that both the AC and DC ground are connected to one common boat ground.
The IC Series’ AC and DC terminals must be connected to the common boat ground to provide an important safety feature. This ground connection can introduce the risk of galvanic corrosion and/or electrolysis of the boat’s underwater metallic hardware. A galvanic isolator or an onboard isolation transformer can be used to prevent galvanic corrosion.
