The Renogy 5 Strings Solar Combiner Box is the ideal solution to combine inputs from up to 5 strings of solar panels into a single output. It accepts up to five 1P miniature circuit breakers and one 2P surge protection device for improved safety of the solar system. The built-in standard DIN rail enables easy installation of the protection devices. Equipped with a rain cap and rubber seals, the grey steel enclosure is designed to survive in outdoor environments. The knockouts are reserved for waterproof strain reliefs or conduits.
Combining up to 5 solar panel inputs into one, and each input can be equipped with a circuit breaker which can protect wires and devices.
The product accepts up to five 1P miniature circuit breakers and one 2P surge protection device. They can provide overload/short circuit protection and lightning protection for improving the safety of the solar system.
Please note all the breakers, interrupter and surge protection device are not included.
Protection level at IP55. It is designed with a rain cap, the double slope design can be more effective to prevent from wind and rain, and makes the outdoor system use safer. The door is equipped with rubber seals which can prevent rain from entering the box.
The diagram detailed shows all components of the box, besides these, waterproof strain reliefs or conduit are reserved for installation.
The product offers a built-in standard DIN rail for easy installation. Mounting holes are reserved on the back for fixationto make sure the box is firm and stable.
When you lock the door, screw the black ring first and then lock it with the key. When you open it, use the key first, and then twist the black ring.

If the panels are grounded to the same rod, I suppose you do not need to add a second grounding. In the case of an electrical storm, the grounding of the combiner panel is of the upmost importance.
No, only panels with the same voltage and wattage can be connected to the same box.
It is mainly used in home kits to combine up to 5 solar panel inputs into one single output, and it can be installed either indoor or outdoor.
Yes, we suggested installing it in order to avoid device damage caused by lightning.
