4 String PV Combiner Box with 15A Rated Current Fuse, Metal Box

The PowGrow PV Combiner Box is very well-made and durable. I always look for features such as ample inner spacing for components and connections. These are more expensive but also easier to maintain/or upgrade. They allow for better heat dissipation. Metal is just my personal choice, although some of the PEP types are quality units but just not as good as the steel especially when it comes to a truly solid surface mount. PowGrow has weather strip, tight closure with robust latch and hinges.

I have had the controller box setup out in the Florida weather (hot direct sun) for almost a year with no problems. It appears very well made with heavy wiring and solid connections. I only have three solar strings attached right now but its nice to know I can add more as I need them. I would very much recommend this box.

Very good I love the quality

Updating my review - after reaching out to the seller for help, he suggested linking my panels in series and running all 6 through 1 port and my voltage shot up as expected. Definitely appreciate the support and follow up from the seller. The boxes are built well with quality components, just understand that these units will parallel all panels so if you need higher voltages to trigger your charge controller you can get by with the 4 port box, as you will need to link the panels in series --- I bought 2 of these powgrow 6x panel combiner, unfortunately neither one works properly. I have all panels volt tested at the cable input, but the boxes do not combine the voltage, I just get a little 19V out of the breaker. If I shut the breaker off I can see 67V but as soon as I flip the breaker on it drops to a universal 19V. My 2nd box is the exact same way, it's like it picks 1 input then uses that as the voltage output and does not combine the power output.

Un buen producto,en México no es fácil comprar un producto de calidad a precio asequible.
