Basic Functional Test - Multiple Inverters
The following steps will complete a basic functional test of multiple Conext XW Pros. If
any test fails, please refer to the Troubleshooting section in the Owner's Guide for
assistance.
To perform a functional test on multiple inverters:
1. Check/verify all wiring and cable connections.
2. Measure DC voltage at the DC terminals on the inverter and confirm it is within range
and has correct polarity. The default acceptable range is 46 to 64 VDC for 48V
systems.
3. Switch INV1 DISCONNECT (DC disconnect switch) to the ON position.
4. Check inverter display for startup self-test during which LEDs will flash momentarily.
Once self-test is complete, the inverter will display Stb. (TheEvent/Warning LED
may flash for a few seconds but eventually will turn off. Ifthe Event/Warning LED
persists, check to make sure a battery temperature sensor is connected. Also, if the
inverter has been pre-configured, it may go straight into normal operating mode).
5. Using the Conext Gateway, set the First (Master) Inverter Device Number:
a. Go to the inverter’s Configuration page and enable Advanced View.
b. Under Device Instance set Device Number to 1.
c. Click Apply.
6. Switch INV2 DISCONNECT (DC disconnect switch) to the ON position.
