The PVI 3800TL, PVI 5200TL, PVI 6600TL, and PVI 7600TL inverters are shipped with 3 X 15 A

600V

Littlefuse KLKD 15 string fuses. The provided string fuses may or may not be appropriate

for your particular installation. Proper sizing of overcurrent protection is based on the maximum

short circuit current Isc (module) and calculated in accordance with NEC Article 690 requirements.

The maximum acceptable string fuse for the string combiner is 20A

PV (KLKD 20) fuse. Use of larger fuses will void the warranty.

The string fuse rating should never exceed the Maximum Series

Fuse Requirment provided by the module manufacturer. This value

is typically listed on the module label.

4.8.5.1.1 Calculating the minimum string fuse per NEC Article 690

The minimum string fuse size is calculated by multiplying the module Isc x 1.56.

For example: if you are using modules that have an Isc = 6.25 A, you would calculate the mini-

mum string fuse size as follows:

String Fuse (minimum) = 6.25 A x 1.56 = 9.75 A

A partial listing of the Littelfuse KLKD Fuses is as shown.
