CNKA solar dc fuse holder Feature

The solar photovoltaic power system is built from interconnected photovoltaic panels. These panels are linked together in series to form strings and in parallel to create arrays. The electricity generated by these arrays is concentrated through photovoltaic junction boxes and then transferred to photovoltaic inverters. These inverters convert the direct current (DC) produced by the panels into alternating current (AC), which can be utilized either by connecting to the public power grid or by powering household appliances directly.

CNKA  solar dc fuse holder FAQ

Q: What type of fuse is used for solar panels?

A: When connecting solar panels in parallel, it's recommended to use a 30-amp fuse for each panel. For panels less than 50 watts and using 12 gauge wires, 20-amp fuses are suitable.

Q: Why are DC fuses larger than AC fuses? 

A: DC fuses are larger than AC fuses because DC current generates more heat over time compared to AC current with the same rating. AC current has an effective value of 70.7% of DC, necessitating larger fuses for safe heat dissipation.

Q: What's the difference between DC MCB and DC fuse? 

A: The main difference is reusability. DC circuit breakers (MCBs) like fuses are single-use devices. MCBs protect against overloads and short circuits by interrupting current flow, while fuses break the circuit by melting in case of overcurrents.
