Installation 

Even the most impressive solar components rely on proper installation to deliver on their promises. The Solreach PV Junction Box OSTA-03 (XY) is no exception. This feature-packed box boasts an IP68 weatherproof rating and UV-resistant shell, but to maximize its effectiveness, a secure and professional installation is crucial.

While the PV Junction B
ox OSTA-03 (XY) itself is built tough, improper installation can compromise its weatherproofing capabilities, potentially exposing wires and connections to moisture and dust, leading to malfunctions and safety hazards.

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 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.
