How to Install
The Solreach PV Junction Box, though small, plays a vital role in the safe and productive operation of your solar energy system. Strategically located on the backside of each solar panel, the PV Junction Box acts as a guardian for the electrical connections between solar cells.
Without proper protection from the elements like rain, dust, and sunlight, these connections become vulnerable to damage and potential energy loss. The Solreach PV Junction Box boasts weatherproof construction, safeguarding these vital connections and ensuring a smooth flow of direct current (DC) electricity.
Step 1
Put the bottom of the junction box up on the glue applicator, and the glue applicator will automatically put the back plate glue into the silicone slot at the bottom of the PV Junction Box
Step 2
Place the electric soldering iron on the bus bar and the tin block, so that the tin block melts and the busbar is bonded to the metal, which can be cooled and solidified.
Step 3
Place the AB glue mixing pipe in the box and start to inject glue until the glue is filled to the overflow position.
Step 4
After AB glue curing Base buckle slot on the cover snaps alignment, surrounded by pre-force, the top cover is pressed into the base.

Safety Measures
Installation
When installing the junction box, make sure the solar panel is not working and you don't touch
the plus and minus rails at the same time to avoid an electronic shock and diode disruption.
Leakage
When installing, evenly smear the silica adhesive on the base of the junction box in order to prevent leakage.
Safety
Do not connect the plus and the minus together of the same junction box at any time.
Efficiency
Keep the rubber clean and no adhesive when assembly, or it affect the efficiency of the panel.
Caution
Do not insert and withdraw the plus and minus connector frequently except repairs because the sealing performance will be cut down.
Substances
Keep paraffin away from PV junction box and connector, such as, oil, lubricant, electric revival, and other paraffin substance.
