The Stacker Cable

The stacker cable provided in the ME-SSI kit is specifi cally de-

signed for series stacking two MS4024 model inverters. It allows

information exchange between the two stacked inverters for two

main purposes: to provide synchronization information while

inverting, and to send a shut down command if a fault condition

is detected. This shut down command prevents any 240VAC load

from receiving only 120VAC power.

CAUTION: Do not use a standard telephone or data cable

in place of the stacker cable or damage may occur.

Info: The stacker cable doesn’t allow programming or

access to the display from one inverter to the other. If

changes or monitoring are necessary, a remote control

must be connected to the affected inverter. It is highly

recommended that you use two remotes in order to

monitor and set each inverter.

Connecting the Series Stacker Cable

The stacker cable is a 48-inch, six-wire, twisted pair cable easily

indentifi ed with a red “STACKER” label on each end. This cable also

has two RJ11 connectors on each end, which allows an easy con-

nection to the Stack Port on each inverter. Once the inverters are

connected as described in the DC Wiring section, the stacker cable

can be installed as follows:

CAUTION: Ensure that no DC power is connected to

the inverter, and that the DC disconnect is open.

1. Locate the Stack Port on each inverter (see Figure 6).

2. Connect the series stacker cable from the Stack Port jack on

one inverter to the Stack Port jack on the other unit.

3. Once the series stacker cable is connected gently pull on the

cable at both ends, close to where they are plugged in, to en-

sure both connectors are secured in place.
