Maintenance:
Replacing the GFDI Fuse
Remove the cap of the GFDI fuse holder to open and then replace the GFDI fuse with the same type and rating (600VDC, 1A).
Before replacement of the fuse, you must switch off the DC/AC disconnect switch and AC breaker and wait for at least 5
minutes for system to discharge.

WARNING!
For continued protection against risk of fire, replace only with the same type and ratings of fuse (600
VDC, 1 A)!
Replacing of the PV String Fuses
The inverter is shipped with four (4) 15A, 600Vdc PV string fuses for PV strings (or three for PVI 3000). However, the size of
the PV string fuse is determined by the electrical ratings of the PV module and by UL and National Electrical Code (NEC)
requirements. The minimum size of the PV string fuse is calculated using the short circuit current rating (Isc) of the PV
module. The NEC requires that the fuse be sized for a minimum of 1.56 times the Isc of the PV module used in the system and
not over the module’s fuse rating. Please be sure to consult with the PV module manufacturer for appropriate PV string fuse
rating. IN NO CASE SHALL FUSES OF LARGER THAN 15A BE USED FOR THE PV STRING FUSES.
