Which makes your solar panel system work reliably and safety. With multifunction: PV array input with first class combination, Quickly cut off circuit, anti-thunder protection, anti-reverse, overload, etc. - Metal box with a lock. Waterproof class: IP65. Durable metal box makes it much more suitable for outside use and installation. It has a longer lasting time than the PVC plastic solar combiner box. The internal mount plate is also made of metal - High quality wires. All wires are pre-wired in the box. Our solar combiner box is used professional wires that are especially for solar system. Built-in with a ground wire connector, the ground wire installation is available. Please ensure the current and voltage of single PV array doesn’t exceed 10A/250VDC. Then you can connect solar panel to the combiner box - Built in with 6pcs individual 15A rated fuse(10x38mm). Max current of single PV input array is 10A. Their function is over load protection. The Combiner Box protects PV solar panel and inverter. Besides it will reduce the length of cable connect from panel to inverter, optimize system instruction makes the system more useful and maintenance. All in all. It will make the PV power system increase output power. - 63A air circuit breaker. It can provide short circuit fault protection and controls the combiner box output. Here is a Surge Protective Device/Lighting Arrester provides lightning protection. The “Green” indicates Normal, once it changes into “Red”. Remember to replace the SPD with a new one. ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B09BTX2YQ5 | | Best Sellers Rank | 1,303,399 in DIY & Tools (See Top 100 in DIY & Tools) 4,034 in Circuit Breakers | | Customer Reviews | 4.7 4.7 out of 5 stars (96) 4.7 out of 5 stars | | Date First Available | 4 Aug. 2021 | | Guaranteed Software Updates Until | unknown | | Manufacturer | PowGrow | | Material Type | Metal Shell | | Package Dimensions | 39.6 x 35.71 x 17.09 cm; 1 kg | | Power Source Type | Solar-Powered | ## Images ![6 String Metal Solar PV Combiner Box with 15A Rated Current Fuse - Image 1](https://m.media-amazon.com/images/I/61QKoP2pvmL.jpg) ![6 String Metal Solar PV Combiner Box with 15A Rated Current Fuse - Image 2](https://m.media-amazon.com/images/I/71Rfi1HbtrL.jpg) ![6 String Metal Solar PV Combiner Box with 15A Rated Current Fuse - Image 3](https://m.media-amazon.com/images/I/71UIeX8fh3L.jpg) ![6 String Metal Solar PV Combiner Box with 15A Rated Current Fuse - Image 4](https://m.media-amazon.com/images/I/71WuyYfdEpL.jpg) ![6 String Metal Solar PV Combiner Box with 15A Rated Current Fuse - Image 5](https://m.media-amazon.com/images/I/71t849REBDL.jpg) ## Questions & Answers **Q: Is this UL rated?** A: No I always call the customer service. **Q: What size wire goes from the combiner strip (at top) to the breakers? #10 = 30 total amps.or #8=55amps. which one?** A: #10 30 AMP Max **Q: Have three strings. I need a 20 amp fuse for one of them, can I replace one of the 15 amp fuses with a 20 amp and keep the remaining fuses 15 amps?** A: For your case, please ensure the three strings' total voltage are close or the same to each other. **Q: My panels have 8.9Amp.Should that be protected by 10Amp fuse?** A: This does not matter. 10Amp and 15 Amp are both can be used. We offered 15Amp. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Well made and it works! *by on Reviewed in the United States 25 May 2025* 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. ### ⭐⭐⭐⭐⭐ Bought 2 - Great support *by on Reviewed in the United States 2 August 2023* 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. ### ⭐⭐⭐⭐ OK but *by on Reviewed in the United States 13 September 2022* The box is ok. Not Shure of fuse holders quality. My complaint with this set is in the main breaker to the controller. It isn't the best has poor wire connectors. If you don't get the + wire going out just so the tightening nut will miss making contact so you will get no connect to your charge controller. We spent hours trying to figure out why it would not wake up our controller. Only by accident did after much hair pulling did we figure it out by loosing and moving work a bit did it make contact.Yes it is working now but I have never seen such a poor wire conect so be warned of this and maybe the quality of the rest of it. There was a review that said he could not get the breaker connects to hold tight. I think it is because there badly made. ## Frequently Bought Together - PowGrow PV Combiner Box, 6 String Solar Combiner Box with 15A Rated Current Fuse, Surge Protective Device and 63A Air Circuit Breaker for On/Off Grid Solar Panel System, Pre-Wired Cable, Metal Box - SUNMAK 16 Units per Set Solar Panel Mounting Z Brackets, Solar Panel Mounting Brackets Lightweight Aluminum Corrosion-Free for RVs, Trailers, Boats, Yachts, Wall and Other Off Gird Roof - GEARit 12AWG Solar Extension Cable (100FT Black - 100Ft Red) Male to Female Solar Connectors with Adapter Tool Kit, Solar Panel Renewable Energy, 12 Gauge Pure Copper Extension Cord, 100 Feet --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.pa/products/449323831-6-string-metal-solar-pv-combiner-box-with-15a-rated](https://www.desertcart.com.pa/products/449323831-6-string-metal-solar-pv-combiner-box-with-15a-rated) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-08-21*
