The SolarCity H6 inverter includes two (2) fuses inside the wiring box for the high-voltage
battery pack connections. Prompt replacement of damaged or broken fuses is critical to
restore battery pack operation. To replace the fuses:
1. Turn the DC Disconnect Switch to the OFF position. If the battery pack includes a DC
disconnect, then turn that switch OFF as well.
2. Move the external AC disconnect / back-feed breaker in the main electrical panel to the
OFF position.
3. Remove the wiring box cover as described in “Remove Wiring Box Cover” on page 59 .
4. Removing the fuse covers (#1 in Figure 10-3 ) by grasping them and pulling them straight
out.
5. Remove the old fuses (#2).
6. Verify that the new fuses you about to install meet the requirements in “Fuses” on
page 66 .
7. Use an ohmmeter to verify that the new fuses are good.
8. Install the new fuses.
9. Replace the fuse covers by pushing them directly down on top of the fuses.
10. Replace the wiring box cover as described in “Refit Wiring Box Cover” on page 60 .
11. Close the wiring box cover by tightening the four (4) screws.
12. Move the external AC disconnect / back-feed breaker in the main electrical panel to the
ON position.
13. Turn the DC Disconnect Switch to the ON position. If the battery pack includes a DC
disconnect, then turn that switch ON as well.
14. Verify that the SolarCity H6 inverter and battery pack are functioning normally.
