VEVOR PV Combiner Box, 4 String Metal Solar Combiner Box with 15A Rated Current Fuse 63A Circuit Breaker Lightning Arrester, Steel Case for On/Off Grid Solar Panel System, IP65

This product came mostly assembled. Internal build quality is 100% spot on. The price point is incredible. Comes loaded with four solar panel fuses, a lighning/surge suppresor and a dual-pole DC circuit breaker that goes to the charging controller. Looks great and has a locking door. The key is a bit primitive, but it seems it seems it is meant as a cabinet key - not a security key. I am beginning to like this VEVOR

A nicely built unit The metal cabinet is nice and heavy but I don't know how it will hold up outside in the weather

VEVOR appears to be a good brand. I bought the VEVOR combiner box for a few reasons. The price was good, It has 15 amp fuses, and the wiring inside is well thought out. The negative wires come in to a terminal strip and only one wire goes to the top of the output breaker. I checked the terminations and all were tight. I cycled all the fuse holders open and closed. I checked continuity throughout and all was good. I couldn't find anything wrong with it. I ended up running three sets of series panels to each input at 80 volts per input for an 80 volt output and 1050 watts. This is going to a shed to charge my Ecoflow Delta Pro. While singing the praise for VEVOR I would like to mention a friend bought a new electric car and needed a level 2 charger. After searching various EV chargers online he ended up with a VEVOR plug in car charger. He knew nothing of the brand before his searches.

It's actually a lot better than what I thought it would be, all of the wires have ferrules Properly crimped on the ends and the bus bar across the top of the fuses, fuse housing very nice touch makes for a very clean install. The box is a very strong plastic and the clamps on them are actually safety clamps. You have to push the bottom lever To pull them up to get it to open, so I'm very happy, if I ever need another one, this will be my go to combiner box. One note People complaining about the wire color really? That's the problem you have? because technically you can use any color you want it could all be the same color so for everyone else ignore those this is a great combiner box.

Came wasn’t assembled missing screws and the fuses are loose easily moved not worth more than $40 max the instructions are nonexistent, even with the pamphlet it came with, does not give you a clear diagram of how to wire plus the mounting is loose when I bought a four wire fuse box from Eco worthy USA it came preassembled I would’ve bought that brand, but I couldn’t find it so I gotta charge $70 for something that’s only worth 40 and I should’ve paid $20 more to get the good stuff but like I said, I couldn’t find it so next time I’ll hold off and wait it out instead of buying inferior products

Very well made. Easy to install and works well.

This is not a plug and play item. Assembly is required. The fuse blocks are roughly installed on the DIN rail. The locking block is on the wrong side of the DIN rail. Causing fuse #1 unable to be opened. Move the locking block to the correct side and it fixed the problem. Wire quality is of unknown condition. It states 2.5 mil (aka 12 awg) wire for the leads but the jumper wires from the fuse block to the breaker is unknown size and the jacket is unknown quality. It does appear to be a PVC jacket on the wire, so I will not recommend going above 300 volt DC. The wire diagrams follow the Chinese standard. Red is hot, blue is neutral, and yellow/green stripe is ground. In this case, red is positive, blue is negative and ground is not really marked except for a sticker next to a wire connecting the door electrically to the frame. There is nowhere in this box to connect to ground. I install industrial solar for a living. I'm using this for a small off-grid setup at home. The equipment I work on is several million USD. Overall this is a decent beginner box. As long as you have some electrical knowledge and know how to assemble a DIN rail.

It was as stated but the wires that were precut and had crimps on the ends were too long.

Buen combinador de energia solar.

Well that simplified everything!!

Works great and gives a professional look and tideness. It also locks to keep curious hands out of danger

Muy compacto

Easy to assemble, everything looks great.
