Never use non-branded fuses and breakers. The DC breaker you showed will likely not function well. They are commonly misrated, and the terminals are too small for the lugs. Great explanation on fusing the solar panel. The DC breaker from the solar panels is not there to protect the wire. It's to provide a mandatory shut off. The wire will be rated higher than 10A, so if a current from the panels is high, it won't melt the cable because it cannot get that high.

Always use a DC breaker (like the cream colored shown) on PV system! If you have an array in series, many mpp systems run 250 to 400 volts so make sure the breaker is rated in excess. Pay attention to the polarity markings on the breaker or the breaker may be destroyed and catch fire. The black DC breakers are for battery voltages only and stay away from the no-name type shown. Use Buss or Bluesea brands.

Thanks for the video. It is very educational. I like the way you explain things, which helps absolute beginners like me. I know the video is about a year old but I am wondering if you could explain a bit more, the protections needed between the battery and the controller. I understand the concept of breaker, which also helps to disconnect the battery power source, but I think you also suggest that the controller also needs protecting, so I don't quite understand that bit. The question is, shouldn't the breaker close to the battery, also protect the controller? And why is an additional fuse needed between the controller and battery breaker, to protect the controller (around 8:20)? I hope my question makes sense. In your example circuit, you have different segments, e.g. PV to Controller, Controller to Battery, Controller to devices/loads via FuseBox, etc. Are you able to advise what type of cable grade is needed/appropriate for each segment in order to avoid the cable melting and potentially catching fire? Thanks.

Hey! thanks for your question. It is a bit misleading because I didn't draw the heavy load like an inverter. This inverter would be connected to the big breaker (e.g. 100A). The additional breaker in front of the controller is to secure the controller (e.g. 20A depending on the controller). That is why I have two breakers in series. A 100A breaker as close as possible to the battery wouldn't protect the controller in case of a faulty circuit because the controller can just handle 20A. Therefore it is good to add another fuse between big main battery fuse and controller. I hope that helped. Regarding the cables you just have to know what the max current is in the respective circuit and then use one of the tables (just google for "wire size amp ratings"). cheers, Lupo

Can you please explain this discrepancy? Thanks.

Hey @truthbknwn, thanks for the question. This is correct, you do not need a fuse as my single solar panel can't produce more than 10amps which is fine for the cables. The problem is the power source on the other side. In case of a faulty controller it might be possible to short the PV and the battery which would lead to a high amp flow. Therefore it is always good to have a fuse between the battery and the controller/PV. I put a breaker between the PV and the controller just to have a switch in between and be on the safe side. Hope that helps? cheers, Lupo

Is it going to work and safe to use a circuit breaker just as a power shut off switch to your solar system from the solar panel lead ins? The reason I ask this is that I found many solar charge controllers do not shut off properly when the batteries get full capacity. I had a solar charge controller melt recently from this and overcharging when it SHOULD have shut off but didn't. But then I found out other solar charge controllers also are not shutting off right. I don't see very many people talking about failures of charge controllers to shut off right also. And it doesn't work to always get the most expensive charge controller out there when you have a budget. So I want to have an off and on switch for when I'm not around. I don't want to take any more chances of not having a shut off, but I don't want to use the plugins for the pv wire connectors themselves as the switch since it would put wear on them.

Suppose I have a 2000 W inverter and want to draw enough power from the battery bank for an 1800 W continuous load with an inverter efficiency of 90%. The draw from the bank would be 2000 W which at 12.5V would be 160A. Should I have a 160A fuse between each battery, or a 100A fuse because the batteries are 100Ah, or do I need fuses between the batteries at all?

I place a circuit breaker in line with anything that is connected to the DC power bus. This offers protection and a means of disconnecting (or isolating) any circuit tied to the bus. That white circuit breaker is a DC magnetic and thermal type, which must be wired in the correct polarity, otherwise the breaker will catch on fire during an overload. The black circuit breaker you show is a thermal breaker made for 24 volts DC maximum. This is a low cost type, likely manufactured in China. I have had so much trouble with these Chinese breakers, I test each one with a calibrated DC current to determine the trip point, as they have a huge tolerance. For the 100 amp type, I have measured trip points from 20 to 70 amps. The fuses you show have a maximum voltage rating of 24 volts DC. You cannot use AC rated switches for DC due to the 10X open circuit gap needed between the switch contacts. This becomes a factor when you go above 25 volts DC (such as a switch to disconnect a solar panel from the solar controller). Using an AC rated switch will cause the voltage to arc across the contacts when opening the switch. I'm sorry if you have covered this in another video but, I just stumbled upon this one of your videos here for the first time. The fuses

@Lupo DIY the amp rating is output, so breaker is nothing to do with that. Breaker should be amp rated to just higher than the max series rating of the panels especially if not fused. However if the maximum current is lower than the maximum series rating of the panels, then no fuse is required. For instance, a Victron smart charge controller 100/50 means maximum voltage from the panels is 100v but the 50 means maximum output from the charge controller is 50 amps. My 1200w at 74v can in theory have the controller output at 54 amps. However this is not a problem but you loose that 4 amps as the controllers maximum current output is 50 amps.

Yes the PTV controller should not output the power to other device it should output to battery only and it should has a dc to AC inverter to power up ur devices. Power from controller to battery power a limited current it don’t too dangerous but power from battery to inverter would be problem it can up to 100A or more do fuse and switch should be add

Hey, thanks for your comment. My Victron charge controller has a dedicated output for the load which is quite convenient as you can switch of the load in case of an under voltage situation. You are right, there can be high current flowing from the battery, that is why I also recommend in the video a fuse as close as possible to the battery to secure the remaining part of the system. cheers, Lupo

Hello. I have two 6v deep cycle batteries each at 225AH and a 100A controller but the current wont pass through the controller to charge the battery. I tested it on one at a time not both at once as i assume the controlle wouldnt handle both 225AH combined. What am i doing wrong
