- This circuit breaker is used in my off grid solar power system that I built. It is available on Amazon:
200-amp Blue Sea Systems Part # 7149:
www.amazon.com/dp/B007P5UNNW/...
I have four Trojan L16 batteries, Outback Power inverter, Midnite Solar MPPT solar charge controllers, Reliance Controls transfer switch, and 3.7KW in solar panels. The system provides off-grid power to my house...yet, I am still "grid connected". This lowers my electric bill 40-50% and I can easily go 100% off-grid if the SHTF. - วิทยาศาสตร์และเทคโนโลยี

Nice setup Chris let me give you a small tip, do amp readings between all your connections starting from batteries to your loads, note the drops and most of all the higher readings it will show your weak conection
Nice Chris!! Sweet and simple.
+BROWERPOWER Thanks man...small steps forward. Making solar power is better than drugs.
glad you found your problem and are making your system safer and more efficient.
Thank you...appreciate your insight/help. How's that tracker working now?
Its working amazing. Tracks closer to sun and in wind very little movement. It was a great investment. Glad I could help you troubleshoot your system.
Love the setup! What gauge of wire do you have running through the 200 A breaker? Looks like at least 1/0 AWG. I like the fact you tagged it with red tape since it's black wire to signify it as positive. It makes mapping and diagnostics really simple. Luckily that poor connection didn't cause a fire man jeez. Have you tried de-energizing the system and doing a resistance benchmark after installing new equipment? That would give you a starting point so every once and a while you take readings and maybe you can spot issues before they become serious. Have a good day!
Hello, Chris maybe need to check the wrong cable connect to Battery on Line and Load to the Inverter. We use this Dc Breakers to protect Winches installed on vehicles. The Line go to Battery and Load go to winch. Is possible check your connection and is good choice because have protection and interrupt switch. Enjoy your Electric backup.
Chris check your local welding shop for 2/00...sometimes you can get retired welding lead for scrap copper price!!...connectors are cheap and can be put on VERY nicely with a chisel and hammer....I'll make you a video if you want....Great system...love the vids...take care
+BlackAck90 Interesting....chisel and hammer, eh? I have been using a shop vise, and punches. I got an actual 12-ton hydraulic crimper on order made for these terminals. They have dyes for different sizes. Pretty cheap too...around $50. Cable is expensive (esp anything larger than 1/0)...so, I will look around. Thanks...and thanks for watching my DIY mistakes and fixes! Haahaaa!
Oh perfect! I have access to a crimper if I need it but a chisel or vice works just as well...take my advise on the cable tho. Good way to get it cheaper than retail! Love the vids. Keep it up!! Looking forward to how the Trojans fair. How much was your 200a fuse? I gotta order one when I save some money. :(

Thanks for the heads up like we've talked, I want to get a set up like yours. Outback and Trojan batteries
Thanks man...we grow/learn from each other. It takes time and money...but the payoff is making your own power and DIY. Nothing beats turning your own wrenches, cutting/slicing up your own hands, swearing like a sailor at times, throwing tools across the garage, working till 2 am on a problem, and then praying like a school girl when you "hit the switch" and turn stuff on...without smoke and sparks. Love it. Absolutely love it.
Thanks for the vid. Honestly when it came to my inverter to battery cables I Overkilled it and got 4/0 Cable. I also used 4/0 Cable for the links between the batteries. Also get Cable with a high strand count.
Thanks man...great advice. 2/0, 3/0, 4/0 cable is not cheap. Also, I used Vaseline instead of terminal dielectric grease...might change that too when I do bigger cables. Your 4/0 cable is top-notch...should have no issues at all.
+ChrisDIYerOklahoma Dang it. I had the same thing happen to my Blue sea m. There must be some thing not right. Brother 00 is the why to go. All my DC wire is 00. Thanks for the video. God Bless.
+yankey4 Amen...you are 100% correct. That fuse and Blue Sea M switch was a "pinch point" and was a weak point. I am going to check the resistance with my meter and see what's up. Time will tell on this pricey DC circuit breaker...looks like it will be okay. Thanks for watching...00 is going to happen on my system.
+ChrisDIYerOklahoma Well Big Cable helps but we all have to remember most cable failure comes at the terminals so always ensure that your terminal crimps are good, terminal bolts are secured and check and re-torque every say 3 to 6 months
Hello Chris, I noticed that your battery cable is connected to the "load" terminal and the inverter cable is connected to the "line" terminal of the new circuit breaker. Am I seeing this correctly? I ask because my Bussman MRCB 150 amp circuit breaker welded its contacts shut (and did not trip). I attached my inverter cable to the "load" terminal and the battery cable to the "line" terminal. I also connected the charge controller red cable to the "line" terminal of the MRCB for charging the battery bank. To make matters worse, my inverter blows 4 of 5 40amp fuses in it any time power is connected to the inverter. This system worked for 2 months before the malfunction. Any thoughts for my issue from you or the forum are appreciated. Thanks for your videos.
any updates on this, most wiring diagrams recommend the first method you used, would love to know if we can scrap all that and just replace with a flush mount breaker like you did. Technically it does the same thing as both the fuse and the switch, and is less complicated...
I like using both a fuse and a breaker...kinda like wearing two condoms.
How to determine dc circuit breaker capacity from battery 200 x 2 system 24v & inverter 1,2kwp
As a follow-up, did you take that switch apart to see how sturdy it was constructed ? Jim
Naw...sure didn't. They are pricey. I am very confident it is built well...meant for marine environments. I tried contacting the company...never got back to me.
Here is some great data on it from the company's website for this breaker: www.bluesea.com/products/7149/187-Series_Circuit_Breaker_-_Surface_Mount_200A
I'm planning on making a setup with Victron MultiPlus-II 5kW inverter/charger with 48V single unit 10kWh ESS bank(20-50Amps average, 100A max) to support my grid tie solar setup in case of outages(anti-islanding support integrated). How has that Blue Sea 200A CB held up over the years with you? Still good to buy?
Yes. A+. Blue Sea Systems makes "the good stuff".
Nice share. How do I calculate the correct size breaker for a 2000watt inverter and a 4-battery bank? How did you choose to use a 200amp circuit breaker in your set-up? Thanks!
*Thanks. Still using that 200a Blue Sea Systems circuit breaker after my rewire this spring. Def get with the company on proper breaker sizing for the 2K inverter. A quick 10-min phone call could save you some $$$. Blue Sea Systems stuff is pricey...but, dam good*
Much appreciated. I know the basics of Ohms Law (watts/volts = amps). In my case, 2000 watts / 12 volts = 167 amps. I assume rounding down to a 150amp circuit breaker would be the better choice versus rounding up to a 200amp circuit breaker. I will definitely give them a call.
*Best to use what the manufacturer recommends and give BSS a call. FWIW, I use a breaker and a fuse for my inverter. Most inverters have a "surge" capability and will draw a massive amount of current for some appliances*
Hi Chris, How do you actually manually trip the MRCB breaker so it operates like a switch? I thought it had a micro switch at the "OFF/TRIP" mark but it doesn't. Do you have to manually move the lever to the off position to operate it as a switch?
Just push the little button and it kicks the circuit like a switch. Or just toggle it.
So you were using the circuit breaker as a bi-directional system? I was wondering if this would work because this breaker has "Line" and "Load" terminals so I just assumed the flow would only be allowed through Line to load and not the other way around.
Give the folks at Blue Sea Systems a call on that Line/Load question. The Line/Load is a polarization design...still should break the circuit at the rated amps/voltage.
Chris DIYer you are correct. They confirmed via email that the breaker is designed for bi-directional flow and will perform in that situation.
Can you use the circuit breaker as a switch by manually pushing a button or flipping a switch??????
Example like in houses , if some body is going to work on a circuit they flip a breaker so the circuit isn't live.
Can you do that with the 12 volt circuit breakers?
Thanks
Shouldn't have any issues doing that...a lot of people do that
Don't you supposed to connect the battery where it says line and not load? or im I wrong
Is the new breaker running with out the heat? How warm is it getting now? Thinking if your little jumper was loose & shorting that may have burned out your 2 switch's
I agree. Temps are great now...just took a laser infrared thermometer reading on it. Ran 130 amps (~3,200 watts) through it...no problem. Highly recommend those little laser gun temp sensors. I did find some heat on the Midnite Solar Baby Big Box DC circuit breakers...working on a solution to reduce heat there (cut some 1" holes, will install some screen buttons, and maybe a micro DC 24v blower fan). That little jumper I had before between the ANL fuse and Blue Sea switch was a bad idea...and the loose connections, and the wrong eyelet size on the terminal lug ends. So many bonehead screws ups. Getting things better overall now...this is why I do these videos...to help people not make the same mistakes I did/do.
So true! The little things make a huge difference. All so found circuit breaker placement to inverter output is very important! keep hi amp draw breakers as close to the inverter output connection as you can.
Question: When adding breaker/fuse, the positive cable length to charge controller is extended with jumper and breaker/fuse. Is it necessary to increase the length of the negative cable also?
Thanks for the video.
it has been around 30 months since this video this blue sea system still working right
Yes...however, I moved it to my other 24v system. Really impressed with Blue Sea Systems equipment...own a lot of it. Not paid by them for adverstising or whathaveya.
Just 12 volt due to additional tie-in to my 12v motor home.
do you think I can get some breaker like this for a 48 Vdc battery bank
*It is stamped "48v" but, I would call/write Blue Sea Systems and check with them before buying this style circuit breaker for your system. Good luck!*
isnt 1 wire bettwen then number 2 wire ? less amps
Hi Chris, in my book, the fewer connections, the better. I cannot picture any sizeable contacts as good as 2/0 to 4/0 cable being designed into those switches ( or breakers for that matter ). Have any of your fuses or breakers ever popped since you installed them ? Also, just using a breaker with the reset paddle would be a quick disconnect ( if needed) eliminating the need for the rotary switch, unless you were going from one source or battery bank to another. You know K-I-S-S by now....your thoughts ? Jim
A lot of guys use a rotary battery switch and a big ANL-sized fuses. I used to do that. It is good. However, I am much happier using that Blue Sea Systems wall mount (surface mount) 48v 200A circuit breaker. www.amazon.com/gp/product/B007P5UNNW/ref=oh_aui_search_detailpage?ie=UTF8&th=1 Heavy duty. When I switched over to 4/0 cable and ran them through that circuit breaker this past summer, I had to modify the 4/0 lug ends to fit onto the two lugs on that Blue Sea Systems surface mount breaker. It is excellent...I used my infrared thermometer at high current load...no heat! Also, it works "both ways"...something VERY important for inverters that are also chargers. Def "Keep it Simple, Keep it sweet".
@@ChrisDIYerOklahoma thank you for this video I plan on using a direct current circuit breaker for my RV
I believe you used a Cooper busman circuit breaker by Blue Sea
Do you recommend that circuit breaker today
@@camposvazquez yes! Good luck with your build
@@ChrisDIYerOklahoma I Apologize fir another question but you have helped me upgrade my RV...
Is it safe to use these switches as a cutoff... Kind of like a battery disconnect... Fir safety reasons.. if I have an issue with my DC to DC changing system.. can I switch it off safely with these circuit breakers?
How is the breaker holding up
100% operational...no issues
Back at ya Chris, I just noted a video placed by PrepareForTheUnexpected and he had a 300A breaker which stopped working. "300Amp DC Circuit Breaker Teardown" He took it apart and as I expected, the gauge of the metal fasteners and contact points were MINIMAL, about the size of a pencil eraser. The points were burned and it would not reset. That is what becomes a weak link ....breakers and friction fit connections in breaker boxes. Much less effective as the old heavy duty BLADE switches like seen in the old Frankenstein movies. Always something to break or create heat/ resistance when dealing with large gauge adaptations. Keep marching on ! A bit more educated....Jim K
Saw the video. People always try to save a few bucks and then end up going with equipment that works (like Blue Sea Systems). The circuit breaker I own/use is CE rated to IP66 standards AND SAE1171 Marine (for use around ignition sources like engine bays and battery boxes). I also own FOUR of their Maxibus busbars. All are very pricey...but, safety/performance/warranty is something those Chinese rip-offs can't offer.
Watch this Blue Sea Systems video: th-cam.com/video/y1eK6oG8v3o/w-d-xo.html
Thanks for the rapid reply. By your suggestion, I have placed a couple of those Blue Sea breakers on my "to buy list " at Amazon. Now I just need to settle on the amp rating. I have ordered 6 Trojan 6V batts from local Continental and already have the 60A Renogy MPPT as well as GoPower 3000A pure sine inverter. Well on my way, with plated terminals and 16ton crimper due to be delivered in the next week. You are a great mentor. Thanks again Chris. I am shutting down for the night. Jim K
That sounds like a sweet set-up. From what you noted, I would use the 200-amp Blue Sea Systems 187-series circuit breaker. Are you going to do a 24 or 48v system?
You shouldn't rely on automatic breakers, secondly main battery switches are for isolating only purposes
You're making a big issue over them there's nothing wrong with them but there is plenty of wrongs with automatic switches
