Using PV Combiner Box, users can connect a certain number of PV modules with the same specifications in series to form a series of PV modules according to the DC voltage range of the inverter input, then connect several series to the PV Combiner Box. Features 1.Equipped with high-voltage fuse and circuit breaker for two levels of safety protection. Multiple PV array input Max current of single PV input array is 10A. Built in with 6pcs individual 15A rated fuse. Their function is over load protection. 2.Install with professional high voltage lightning arrester, both positive and negative poles with anti-thunder protection function. 3.Professional high voltage Air Circuit Breaker controls output, with anti-circuit protection function which makes the system more reliable and safety. 4.The wires are pre-wired in the box. They are used with high quality wires especially for solar system. 5.There are Heat Insulation Devices between Fuse Holder, SPD and Circuit Breaker. Increased the installation distance between them. To improve the heat dissipation effect.6.A waterproof and anti-rust lock is installed on the box to prevent others from opening the combiner box. Technical Parameters Max.

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. Review: Make sure and check all screws are tight on the lugs - Works well for what I needed ## Features - Professional PV combiner box is suitable for your Photovoltaic On/Off-Grid Solar Power Generation Systems. 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 | 1,321,249 in DIY & Tools ( See Top 100 in DIY & Tools ) 4,103 in Circuit Breakers | | Customer Reviews | 4.7 4.7 out of 5 stars (98) | | 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) ## 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 ### ⭐⭐⭐⭐⭐ Bought 2 - Great support *by C***N on 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.

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. ## 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.tw/products/449323831-6-string-metal-solar-pv-combiner-box-with-15a-rated](https://www.desertcart.tw/products/449323831-6-string-metal-solar-pv-combiner-box-with-15a-rated) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-10-06*
