AC Wiring - General

Neutral Bonding

The HOT output of each inverter provides 120 Vac to neutral. The voltage between the HOT outputs from the L1 and L2 inverter is 240 Vac when the ISC-S cable is used.

When using a series-stacked, inverter configuration, it is important to provide a neutral bond between both inverters. Accomplish this bond by establishing an inverter-to-inverter neutral bond.

Keep the neutral bonding jumper as short as possible to provide a better AC “zero volt” reference for each inverter to measure AC voltages from, as well as saving on wire. The neutral bond wire must be the same gauge as the other AC wires attached to the inverter.

Grounding

Ensure all components are grounded properly for safety and for code-compliance.

WARNING: Hazardous Voltage

When stacking inverters, ensure the chassis of each inverter is connected to the same common ground (i.e., in the utility or inverter panels); otherwise a hazardous voltage may be present between the chasses.
