Rated. / 5. Based on customer reviews
DANGER:
Cette unité contient des dispositifs de stockage d’énergie qui prennent
jusqu’à 5 minutes pour se décharger. Vérifier que les condensateurs à haute
énergie sont complètement déchargés avant de travailler sur l’unité.
DANGER:
Verify that no shock hazard exists between both fuse terminals and earth
ground before removing the fuse. A 600 V rated fuse pulling device is
required.
DANGER:
Vérifier qu’il n’y a aucun risque d’électrocution entre les deux bornes de
fusible et la prise de terre avant de retirer le fusible. Un arrache-fusible d’une
capacité de 600 V est requis.
1. Open the DC side door and locate the DC distribution PCB.
2.
Inspect the 5 A GFDI fuse for continuity using a multimeter.
3. Remove the GFDI fuse.
4. Check for continuity (ohms) across the GFDI fuse.
If the meter indicates no continuity then a ground fault likely exists.
◦ Check the DC voltage between the grounded terminal of the array and earth
ground. The voltage should be less than 30 volts with the GFDI fuse
removed. If the voltage is higher than 30 volts, a ground fault likely still
exists. Check the array wiring. For the best results, perform this test with the
DC disconnect in both the ON and OFF positions.
◦ Make sure the grounded leg of the solar array is not disconnected in the DC
disconnect.
5. Once the ground fault condition has been eliminated, verify the voltage
between earth ground and the grounded side of the PV array is less than 30
volts.
6. Ensure the DC disconnect is in the OFF position and install the new GFDI fuse.
7. Restart the inverter.
If the ground fault cannot be eliminated, contact AE Solar Energy Technical Support.
