8. Turn on a 120VAC load powered by the inverter feeding the L1

terminal and verify that it works. Turn on a 120VAC load pow-

ered by the other inverter which feeds the L2 terminal and

verify that both of these loads work. Turn on a 240VAC load

works correctly – leave all these loads on.

Testing AC Transfer/Charge Mode
9. Check the AC transfer. Apply AC power to both inverters, after a

few seconds:

a. If using the remote control – wait till the CHG LED on the

remote control for both units stops blinking and comes on sol-

id. Press the INVERTER ON/OFF button to disable the Inverter

mode and verify the INV LED turns off, and that the loads con-

nected in Step 8 continue to work.
b. Without the remote control – the Status LED on both invert-

ers will come on. Press the inverter’s Power ON/OFF switch

and verify that the loads connected in Step 8 continue to work.

10. Check the Charge mode. Verify the batteries are being charged

– may take minutes before the charge current is actually seen.
a. If using the remote control – monitor the CHG LED on the

remote, if it is blinking on either remote, press the CHARGER

ON/ OFF button on that remote to turn the charger on. Verify

the CHG LED on both remotes are on solid (not blinking) and

the remote display shows that they are both in Charge mode

(i.e., “Bulk Charging”, “Absorb Charging”, etc.).
b. Without the remote control - the Status LED on both invert-

ers will come on (the LED will be on solid or blink depending

on the Charge mode).

This completes the functional test. If the inverters are function-

ing correctly as a series stacked pair, continue to the Inverter

and Charger Operation sections. If any step did not operate cor-

rectly, refer to the Troubleshooting section in this manual or in the

owner’s manual for your inverter.
