    Really Great product ! I was using MNPV3 but I needed a bigger combiner box, so I brought MNPV6. And it’s perfect ! Midnite combiners are great for PV off grid installations.


  3. Phyllis T Visconti

    Good instructions included. Can be used in a variety of ways. A bit pricey for a metal box. Easy slide on breaker DIN breakers, solid construction !

    Received on time. Pretty basic and easy to install. It’s a basic combiner. Does exactly what I need it to do for my power plant and has room for me to expand it.

    I have used Midnite solar combiner boxes in the past and they are the best. Plenty of room inside the box for all the wiring. Product as expected. No issues.

    This is another great product from Midnite Solar. I like how well built the box is and the fact it’s made from aluminum. This should last for a very long time.

    Good things are: light, sturdy, plenty of bus capacity, comes with DIN rail already mounted, comes prepared for either fuse or breaker installs, has many options for knockout locations, top notch and easy to read instructions, ability to run 2 isolated strings through this box, easy to install!

  11. John E Jennings

    I’ve used many boxes for my solar panels. But they don’t last for long. They get rust after using some month because of the environment. I get the best result with it. Using since six months and still no rust or dent. Made of high-quality aluminum. Loved it. value for money product!

  12. Howard C Rivera

    Everything is pre-wired, all you need to do is snap the solar connectors and insert the wires to the charge controller.
    Very easy setup.

    Great product, prompt reply, and professional customer service. As an Electronics field engineer, I have seen many products, read their manual, and did my research for a while before buying this product. I finally purchased the Midnite Solar Combiner Box. This one has one of the best Electronics design for the price. I would buy this product again!

  15. James V Christensen

    I am using this combiner box for a DC system and am very pleased. It is a bargain compared to buying the parts separately especially when considering the professional clean install in the box. The combiner, lighting arrester, breaker, universal solar panel connectors, grounding bus-bar. Good stuff – using one month, no problems.

    James V Christensen

  16. Carmine S Thompson

    Exactly as advertised. I made some changes to connect two charge controllers and it’s working perfectly.

    Well constructed box, easy to work with. Did some mods by adding marine high-amp breaker as a central disconnect. No problems so far!

    If it find something failure, DC breakers will protect wiring from potential fire in the event of module failure. It’s a very safety issue. Which is provided in this Solar Combiner Box.

  22. Michael E Crosby

    It’s very well put together. It’s exactly the size I need, and the box is very solid. The wiring looks to be of good quality and everything is tidy and well organized. It’s really going to make setting up my PV system a lot easier.

  23. James R Mack

    Made my off-grid solar project so much easier and professional. I feel so much better having this instead of something I would have to piece together and possibly get wrong. Instructions are a bit light but have everything you need. Pretty much plug and play.

  24. Christian A Crisler

    I have installed two of these units, each with four 330 watt panels, at home and my folks’. The only complaints I have are the accessibility of the grounding wire and that if you don’t mind the length of cable to make a bend, the plastic connector to the outside may dislodge. Other than that this unit works awesome!

    It makes your installation a bit less painless and protects your solar panel investment.
