JTRON 15A Solar Connector Fuse Solar Surge Protection
WHY WOULD I NEED SOLAR FUSE?
Solar fuse can be the additional protection to prevent your expensive solar appliance from too hot or fire when the power surge occurs to your solar system. The solar fuse can quickly interrupt the circuit once the fuses rated amperage is exceeded. Keep your solar system safe, also keep you safe.
HOW TO CHOOSE A PROPER SOLAR FUSE FOR MY SOLAR PANEL?
ATTENTION: It is needed to consult an electrician about the question before you buy it if you are not clear about this problem.
IF YOU USE THE PWM SOLAR CONTROLLER: The short current in the solar controller and fuse are the same, so you can choose the solar fuse according to the PWM controller specification.
IF YOU USE THE MPPT SOLAR CONTROLLER: There will be a recommended fuse size in the controller user manual. Also, you can consult an electrician about it.
