The conventional diode in the junction box is a by-pass diode, which is mainly to prevent the damage of the solar panel caused by the hot spot effect caused by partial shading; Bypass diodes are installed for panels greater than or equal to 75W, and
(1) When multiple groups are used in parallel, one group of wires is connected in reverse, resulting in diode reverse breakdown. (2) Under repeated shading in a short period - no shielding, the reverse, and forward conversion lead to thermal breakdow
A solar panel can come in several ways. 1.) Without any cables attached to the junction box. 2.) With standard 0.9m thick cables with bare-end cables. 3.) With standard 0.9m thick cables with common solar panel connectors. 4.) With standard 0.9m thic
The length of the cable on the panel is standard. If it does not meet the requirement, you can:. (1) Choose the model without the cables and choose the cables under the “Accessories” section on our website. (2) Choose the model that comes with the ca
(1) Without Connectors: use directly or order the required connector under “Accessories” and customize your very own solar setup. (2) With Connectors: choose the required length of cable based on the connector type. It is safer and more convenient to
