power Inverter Stacking Installation Guide

What it
does
The ISC-S cable provides communication between the two stacked inverters for two
purposes.
• It provides synchronization information for inverting and charging.
• It provides a method for one inverter detecting an error condition to send a shut-
down command to the other inverter, to prevent a 240Vac load from only receiving
one leg of power.
What it
does not do
The ISC-S cable does not allow programming or access to the display from one inverter
to the other. If there are changes to the default setting necessary, each inverter must be
programmed separately. This includes selecting “On” in the “On/Off” menu.
