UPDATE: the NH00-fuse has an Icc of 25.000A, not 120.000A as stated in the video. 🎁 Free diagrams: cleversolarpower.com/free-diagrams/ 📖 My best-selling book: cleversolarpower.com/off-grid-solar-power-simplified
You better make sure your recommendations are correct, the NH00 fuse from siemens does not have an ICC of 120kA at DC voltage, it's only 25kA. Have a look in the datasheet.
Renogy sells an ANL fuse rated for 72v and provides a spec sheet. I'd be interested in your thoughts on. It is the only ANL fuse I can find rated more than 24v. Thanks for the valuable information.
Good info.I was looking to upgrade fuses and battery shut-offs.I have cheap fuse you showed ,top left one showed in group of 4. My positive shut off post gets warm from 800 watts using 1500 watt heater on low.I know heat makes them fall apart.Bussman 187 series push button disconnects are $55.
I recommend using the disconnects switches from bluesea systems. They have less resistance. Read my article on my website about 'how to calculate power loss in a circuit'
Thanks for a super clear and informative video - So i am correct im thinking that with a 12v 105ah lithium battery i would be ok to fuse the main connection from the battery with a suitably sized midi or mega fuse ? 105x10 = 1050 amps max during short - IIC for a midi fuse is 5000A and 2000A for a mega
Hello and congratulations for the tests with the fuse I would like to ask you something I have a large LFP battery pack (EVE 280K) in 9S 4P or 28 volts 1120AH and my voltage converter is 4000 watts to 28 volts which fuse do you recommend between the + of the converter? 150A? fuse like yours or a fixed fuse like VICTRON? THANKS laurent
I have found Class-T fuses lower than 100A from Bussman and LittelFuse in my searches. Am looking to get an 80A (something like LittelFuse JLLN080P 80A 200KA) for a 48V LiFePO4 battery but no clue which holders will work with that. Wish they were sold as a pair.
The holders are sold separately. Make sure you got the right one. There are different ones for different currents. I think there are two types sold by bluesea systems.
There are two from Blue Sea systems, they are both too large. One is for 110-200A and the other is from 225-400A. I can't find the one I need which is for 70-100A.
@@ML-hf6ii I experienced the re-bridging of the fuse element when I used a 80 amp ANL on my 48 volt AGM pack. I had used the ANL as a temporary fuse and it became the permanent. One time my voltage was low on batteries, I plugged into shore/ utility to recharge and that higher than normal current took out the 80 amp ANL, which was still arcing after the main element blew. This video has great info.
@@ML-hf6ii You can trust Victron's product to perform as they specify by way of their reputation. 95% of other ANL fuses are no name copies. I'm sure Victron can elaborate on how their ANL fuse is higher voltage capable.
except choosing fuse 10 times more than battery capacity, there should be like a precise formula with battery voltage as well, as energy of short circuit battery or power source is Amperage x Voltage x time ....
It is not the fuse rating. It is the short circuit fuse rating, these two are totally different. As you can see on the table different voltages have different short circuit current.
Please help, i have a 5000watt inverter, 4 x 200 amp hour AGM batteries , and 4 230 watt panels. I think i need a 400amp Class T fuse, but i dont know where to put it ? 12v system Please advise.
An MCB is more expensive than a fuse. MCB's are used in AC switchboards. In a DC circuit the fuse wil seldom trip, so that's why we use a fuse. However, and MCB is used as a disconnect between the solar panels and charge controller.
@@cleversolarpower when you were saying "fuse/breaker" is US$15 dollars, I was thinking that an AC MCB is US$6 and doesn't have to be replaced when it activates.
