FINALLY Got This Done! DIY PV Junction Box for My Solar Setup

After months of planning, I finally finished building and wiring my custom DIY PV junction box! This isn’t your typical solar combiner box—I'm not combining strings but instead creating a clean, organized, and safe way to bring multiple PV lines into the house. In this video, I’ll walk you through my layout process, the components I chose, and the step-by-step wiring. Whether you're building your own solar system or just curious how to manage outdoor PV cable entry with built-in safety features, this should give you some great ideas. 💰 Bonus: I’ll also compare the cost of this DIY junction box build to the pre-built combiner box I installed last year, so you can see how much you might save (or spend) depending on your route. 🔧 What’s included in the build: - Waterproof enclosure - Surge protection - Inline disconnects - Grounding points - Future-proofing for expansion 🛠️ Parts & Components (Affiliate Links) 🔹 VEVOR Electrical Enclosure, 20x20x6in, Tested to UL Standards NEMA 4 Outdoor Enclosure - https://www.vevor.com/electrical-enclosure-c_10749/vevor-electrical-steel-enclosure-box-nema-4-outdoor-enclosure-nbsp-20-x-20-x-6-ul-p_010433852983 VEVOR 5% Discount Code: VVPROMO 🔹 VEVOR Electrical Enclosure, 20x20x6in, Non-UL NEMA 4 Outdoor Enclosure - https://amzn.to/4lqsVKI 🔹 Chtaixi DC Miniature Circuit Breaker, 2 Pole 1000V 25 Amp - https://amzn.to/4ka14NL 🔹 Dinkle DIN Rail Block Kit - https://amzn.to/3ZSzjlJ 🔹 2 Pieces DIN Rail Slotted Aluminum RoHS 12" Inches - https://amzn.to/44CeuO5 🔹 UL Listed Wire Ferrule Connectors 10 Gauge - https://amzn.to/4noVidY 🔹 Surge Protection Arrester Device, 2P DC - https://amzn.to/46kp1P6 🔹 HKS Ratcheting Crimping Tool Set - https://amzn.to/46jEsai 🔹 Industrial Hydraulic Cable Lug Crimper 16 Ton 9 AWG to 600 MCM - https://amzn.to/4l0Sy4Y 🔹 VEVOR Digital Torque Screwdriver - https://s.vevor.com/bfRcyt 🔹 Watts247 4-2 PV Combiner Box - https://watts247.com/product/solar-panel-combiner-box-4-circuits-to-2/?wpam_id=126 🔹 BLUETTI EP800+B500: https://shrsl.com/4lxum Discount Code: AdamEP800 - 5% Off For more details, visit my website: https://going-off-grid.com 💡 Support the Channel Want to support my work?
