What Is The Amp Draw For A 5000 Lumen Led 12vdc Light Draw
- #i
So I was merely running a test on the Air Conditioner. Lol but my wife fired up the Microwave while it was running... Long story short I blew the main fuse to the inverter... At present ordinarily this would NEVER happen... Simply a failure in advice... My error in fact
Co-ordinate to the Aims Power remote brandish it was pulling at 98% capacity for a few minutes...
What would be a typical fuse for something like this? Furthermore would information technology need to exist a SLOW blow fuse?
Update:
So this is a low frequency, 12v, 3000 watt inverter... Capable of up to 9000 Watts acme (not that I would ever hit that)
Would a slow blow fuse make more than sense than a a normal fuse?

I suppose a amend pick would exist simply to not use the microwave when running the air conditioner

The fuse to the inverter should exist easy to read and replace.
Or if you mean the fuse in the inverter, and so you'll likely need to open it upwardly anyhow, if you lot intend to replace it yourself.

I accept already replaced it, only I would think that it should be able to not accident a fuse at/near full capacity...
Then this is a low frequency, 12v, 3000 watt inverter... Capable of upwards to 9000 Watts pinnacle (not that I would e'er hit that)
Would a deadening blow fuse make more than sense than a a normal fuse?

What was the fuse amp rating that blew?
3000W / 12.8V = 235A
With .85 efficiency, thus input .xv college… 276A
With 25% headroom, 345A fuse.
Here is the all-time answer, using typical inverter 10V cutoff (from adjacent post below):

I have found between my wife and two kids and I, running only one high wattage appliance at a time is non an option, so the arrangement needs to handle two.
How thick is this wire? With such a surge capability, I would like to know what this does to wiring.
Before you get to the fuse, I would brand certain the wiring tin can handle 3000 watts. I had a 12 volt inverter 200 watts I used four/0 for, and I replaced that with a 3000 watt 24 volt inverter with the aforementioned 4/0 wiring. I calculated the 3000 watt inverter to demand a 225 amp fuse, so at 12 volts a a 3000 watt inverter would need a 450 amp or 500 amp+ fuse.
Inverter Wattage divided by depression voltage cutoff divided by inverter efficiency multiplied by 1.25 for headroom.
3000/10/.85*1.25=441 amps
If you can conform the depression voltage cutoff somehow, than the amperage volition drop fairly significantly.
Now for choosing the ampacity of the wire, the manufacture spec sheet would be the way to go, but I plan off this, but note some higher temp insulation or busbars will let more amperage than this nautical chart, merely manufacture spec:

Without knowing how a low frequency inverter is fused for surge, I would go with a 250 amp fuse.
I'd honestly fuse to the max ampacity if the wire at the insulation you have.
In the chart I posted earlier, that 250 amp fuse is based off 90 c insulation would be 260 amps max. If y'all have 200 c wire that could be college.
250 amp fuse would be skilful for most voltages while the SCCs can assist in ability, but may be pushed to its limits or past when information technology's nighttime time or before dawn and the battery is it'southward lowest and the 3000 watts is used.

Edit: what size fuse blew?

Aye I don't intend to ever run anywhere well-nigh those wattages realistically I think it's unlikely that I will e'er be any college than ii,000 Watts under normal circumstances

Fuses I've seen tin agree between at 100% & 115% of rated chapters, "forever."
Yous have to see the "immigration fourth dimension" bend. It's commonly plotted on log-log paper.
see page 9.

Yous are looking at upwards of 300 amps of inverter electric current.
Inverters regulate output AC voltage so for given AC load ability, the more DC input voltage driblet on inverter the less the inverter efficiency and the more DC electric current it draws.
When using merely 12v high power inverter, cable voltage driblet is very important and almost ever more critical than cable ampacity.
Four foot 2/0 cable pair with connector lug is going to requite you about 0.ii vdc cablevision drop. At 275 amps at that place is nearly 50 watts of heating to cables so they will go hot.
Anything less than 2/0 cable is too pocket-sized. Consider using iv/0 battery cables.
But the terminal lugs where they neck down to the terminal flat portion is going to become warm. Get the thickest guess metal lugs y'all tin can detect. Admittedly stay abroad from cheap thin metallic wall terminal lugs.
Get a cheap IR temp measuring gun. to bank check every connection.

Currently the mode that I am wired is equally seen in the motion-picture show the solar accuse controllers are connected at the fuse connectedness closest to the blueish bounding main switch on the inverter side
And on the negative side the SCC is tied in at the BMS to inverter junction seen in the pic should likewise mention that the total length of 1/0 cable from battery to switch is around 4-v anxiety... Then about iii feet of 4/0
I take been because reworking the mounting point for the inverter in society to bring the overall Length of 1/0 down to 2 feet...

So if you expect at the motion picture above the iv/0 wire going from the blue sea switch to the fuse and the four size heater wire going from the fuse to the inverter on the positive side are both getting quite warm but none of the other wires are getting hot at all... Not even the 4/0 negative
Anyway I found that it would blow a fuse if you tried to start the air conditioner too soon after of course I can solve this past doing a soft start
Only when I went to replace the fuse I noticed that ane of the counting prongs had broken off just completely cruel off the fuse
So it's got me wondering could my problem actually exist a bad fuse.. non all fuse manufacturers are the same

It's interesting to note that the tabs basically bankrupt off merely if you wait there's near no surface expanse I recollect the actual failure here is not a failure of the equipment merely rather failure of the fuse I may go to two smaller fuses putting one on the acme side of the final and one on the bottom side as opposed to trying to pull all the current through 1 large fuse... Mayhap pull all the current through smaller fuses something tells me that will work better cuz I remember what's happening is these fuses are choking everything out

I hateful how does 200-300 amps pass through something so pocket-size without issues?
