Application
Used for photovoltaic systems
Solution
● The JB mounting hole of the terminal base must line up with the ribbon of the PV module.
● Compound for sealing and adhering Applying potting glue requires a precise kind and specification. Make certain JB will be fixed in the appropriate location with a trustwort sealant. Diodes and the terminal base’s top surface should be covered in potting glue. to reduce the risk of electrical shock.
● Avoid moving the PV module or JB until the potting glue, adhesive, and sealing compound have fully hardened.
