HQST Solar PV Fuse 15 20 30A from Panel PV to Controller, Controller to

HQST 15A, 30A Solar PV Fuse Holder from Panel to Solar Charge Controller OVERVIEW This product is a 15A/30A fuse embedded in a waterproof fuse holder. It has male and female connector leads on each end, making it compatible with adapter kits and solar panel leads. Compatible with PV cables with different insulation diameters.Designed for various DC applications.This fuse holder is designed to provide complete single circuit protection for your solar array. The fuse can prevent high current from damaging the solar panel. Purchase this product to provide additional protection for your system. 1 Year Material and Workingmanship Warranty. How to choose fuse The size of this fuse is dependent on how many solar panels you have and how they are connected (series, parallel, or series/parallel). If the panels are connected in series, the voltage of each panel is added but the amperage stays the same. And for the amperage of the panel, you will need to check the rated short circuit current (Isc) value for the panel your are using. The short circuit current (Isc) is the largest current that the solar panel can produce under any circumstances. For example, if you have two 100W panels connected in series, each producing 20 volts and the rated short circuit current (Isc) is 5 amps, the total output would be 40 volts and 5 amps. We then take the total amperage and multiply it by a safety factor of 25% (5A x 1.25) giving us the fuse rating of 6.25A or 10A if we round up to the nearest available fuse size. Parallel Volts: V1= V2 = 20V Parallel Amps: (A1 + A2) * Safety Factor (1.25) = (5A + 5A)* 1.25 = 12.5A or close value HQST 20, 30A ANL Fuse with Transparent Holder, Fuse from Solar Charge Controller to Battery Overview The HQST ANL Fuse Holder with fuses are used in electrical systems in which the fuse is designed to burn out when the current exceeds the safe limit for the device being protected by the fuse. This product is composed of alloy and brass copper materials and comes with a clear protective non-conductive resistant cover. This fuse set is ideal for custom installation. How to choose the fuse
The specification of the fuse between the battery connected to the controller is the maximum output current of the controller as the reference. The selection of wire diameter is based on the maximum output current of the controller, and is calculated according to the wire diameter current-carrying table. For example, If you have a 30A controller fully loaded, the fuse should also be 30A. On Mar-15-22 at 23:51:03 PDT, seller added the following information:
