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.
