Removable Plate Design Cover
Circular cover - remove from cover for wiring or keep it on cover to shelter the exposed parts to prevent short circuit Waterproof rings act as sealing function and makes wiring is more secure and reliable.
4×5/16"(M8)+2×3/8"(M10) Studs
The size of the terminal can be selected, more convenient. It makes the terminal block be able to accept 4/0 Gauge wires and terminals and can allow max 500A current pass through the battery terminal block.

I recently incorporated this heavy-duty 500A marine bus bar into my off-grid solar system to parallel two 48V 540Ah IFLA battery packs. With each battery pack outputting 200A, this 500A busbar perfectly meets my needs. The waterproof design with six sealing rings ensures reliable connections, crucial for outdoor installations. I appreciate the chromium-plated copper plates for their low resistance and corrosion protection, while the flame-retardant nylon cover adds an extra layer of safety. The removable circular covers make wire management easy and prevent short circuits. Overall, this busbar has proven to be a robust and secure solution for my high-current solar setup.

Using this on my 48V off grid batteries, have almost 100AMPH of batteries, although never pull more than 100AMPs these have been working great with no heat build up.

I used this on my 4Kw inverter and it works great. The copper plate is supposedly purple copper of which based on my tests, may be accurate as it has very little resistance. Connections are perfect for 4/0 connectors and make good contact as expected with the decent studs provided.As others have mentioned, the little circles tend to fall out easily, but just get some rubber electrical grommets to plug up the holes and all is good.Only thing I didn't like is you cant really disassemble it. The studs are implanted in the plastic and the back circle covers are glued in, so the only way to get it apart is to drill them out to get the studs out. Would have been nice if the studs could be removed. Other than that, worth the investment for a good buss bar.

I am torn on how to rate this product. It is truly heavy duty. I’ve setup two sets of solar battery arrays using a variety of bus bars over the past year. Some are clearly better than others with the cheapest $20 units being fairly light weight. They do the job and can easily handle the 100 amps of DC voltage without concern. However I would not trust some of those lower end units to handle the 200A if the DC to AC inverter were ever to be under a surge load or even operating near continuous peak output.In the middle are $40 or so bus bars that are a big heavier gauge. Thicker contact metal with a more solid feel on the posts where you mount things like battery lugs or other wiring in the system. They work well and can likely handle the higher loads needed.However both of these configurations are somewhat rudimentary bars with a simple “bridge style” cover.This unit is different. First of all it weighs a LOT more than any other bus bar pair I’ve had my hands on in the past year. That is at least a half dozen to compare it to. They are not even close to the weight of these units. The mounting plate is solid and has a large surface area. The threads are solid and this setup can easily handle some fair large battery cables. I’ve not tried wiring up the 2 gauge or thicker cables yet, but it looks like the ports on this and the lugs can handle something close to that, if not the 2-gauge definitely the 6-gauge we use often in some of the subcomponents.I really like the ready-to-go knockouts, 3 top, 3 bottom, and 2 on each side. I also like the weatherproof gaskets to keep dirt and dust mostly out of the enclosure.The two things that have me hesitant to give this a 5-star rating: 1) the lack of smaller gauge screw connectors that many other $40-or-so bus bars have. Though I get the thought of not mixing high amperage/voltage stuff with low amperage stuff, both of which tend to use distinctly different guage wiring so maybe a separate bus bar is wise. 2) The price. This bus bar is nearly twice to cost of any other. That said it is easily twice the weight of any other and it is truly heavy duty, but I’m not sure that justifies such a steep upgrade. If money is no object and you want a solid bus bar that can easily handle some fairly big power requirements, then it truly lives up to the heavy duty tag.

I have done a number of solar projects and have used several DC bus bar blocks. So I ordered these for a large project I have planned. I have to say, these are VERY nice - considerably better than I anticipated when I placed the order. They are very heavy duty and appear to be very high quality.The busses are very heavy duty with 2 sizes of studs and nuts - this should be good when doing high amperage setups with things like 00 and 000 AWG terminals. Construction is very robust.The busses are encased in plastic cases, and the outside edge of the cases have holes drilled with "plugs" in them. 3 holes on each side and 2 on each end. You also receive a set of 6 grommets for each one that can be used to do make it more water resistant, thought it really isn't. But it will protect it against dust and a splash out of it. That being said, some silicone caulk might be able to make it such. The cases come with hardware to secure the top to the bottom.Overall, these are extremely nice bus bars and will work perfect for any project that requires how power/amperage bus bars. They will be perfect for our solar/inverter project.

This MOFEEZ power distribution block truly is heavy duty. I attempted in two pictures to show base bar is tinned copper. I filed a deep v out of base bar to reveal a copper core. Many of these commonly available buss bars and distribution blocks use cheaper brass.Mounting base provides excellent isolation and dust protection. Question claim of being waterproof but not crucial for my 12v and 24v systems. The two m10 studs provide ample surface area and torque for 4/0 primary connections. There are also four m8 studs to handle up to 2/0 feeds. I appreciate the multiple wire feed access points as it gives options for wire management.Little on the pricy end but being pure copper it is easily justified for offering less resistance in connections and higher current capacity.Keeper!
