If I install a 200 watt max. inverter to the controller, and install a .5 amp ac load to the inverter, what size awg wire would you recommend?

We do not recommend connecting the inverter directly to the charge controller; connect it to the battery instead. 8 AWG be sufficient.

I promise you, this inverter cannot handle 200 Amps. It's output rating is around 4 Amps (400w/110v=3.6A) at 75% efficiency, the input current would be around 45 Amps (400w/12v=33.3A /0.75=45A).

Clarification: you are fusing the wire and not the inverter. But assuming you have sized your wire correctly for the distance needed you should install a 200 or 250 amp fuse depending on the intended use of the inverter. If you plan on using the full 3000 watts or the 6000 watt startup surge on a regular basis use the 250 otherwise 200 would be safer.

I have used 14-2 solid copper romax, from a 210W Evergreen panel and it worked OK. About a 15 foot run. Also used 18AWG hook up wire from a 150W German panel, a short run about 6 feet. Ran the inverter about 6 - 8 months with the 18AWG. I did notice when the panel was outputing about 120W - 125W the wires were harm. I have since switched to 10AWG. If you do not need MC-4 connectors you can buy automotive inline connectors. The male and female will fit the MC-4 connector if you do not over-crimp the connector and flatten the connector insulation.

4 AWG wire can actually handle 150 amps up to13 feet. But i personally wouldnt use 4 AWG for more than 10 feet of power cable. So depending on how long your power cable is you should be fine. Crutchfield has a great wire size chart on their site

Hi Janet, wire gauge is 16 AWG, comes with a 5 Amp fuse. but now I use it with one of 10 Amp. through it start to run a 120V power inverter 375W

Personally I would use 18 gauge wire, your load is less than 3 amps. 18 Ga wire is over engineered for the load and it has mechanical strength.

Ideally, you should use a 200amp fuse if I understand your question correctly. Wiki American wire gauge for more info.. Hope this helps.

I used size 4 for all my solar needs panels to controller to batteries from there to fuses to inverters. mite be over a little. But I don't have to worry about wire size. and it fits fine on my controller. I am not loosing any power due to that size. and I had problems with this controller!

I would connect up no more than 400 watts of panels. In my experience, these inverters are not conservatively rated. You are especially at risk when the sun first strikes the panels on a very cold day. Stay with 400 or less and you will be fine. I tried connecting (2) 280 watt panels and the inverter fried. This is fairly common. Check on Utube for similar experiences.

I would wire them as Anthony Gomes answered. Keep in mind the high current draw possible with a fully loaded 2000 watt inverter on the 12VDC input side. Use the shortest cables possible, and large enough to handle the high current, with good quality, secure connections.

You can never go wrong adding an in-line fuse right of the battery connection. Most professional installs will place a fuse in the first 6-12 inches of wire/cable. The distance of the cable and constant watt draw does matter on the size of wire used. I will be using 4 AWG since I will be running it over 15 feet or so for a permanant mount in my truck. If they are recommending running 8 AWG wiring, it would be a 100 amp fuse by US standards for 12v applications. This would be at a full load.

The Inverter has a GFCI protected outlet which will trip on ground fault. The Inverter will shutdown if there is overload on A/C output. On the Input side (12 Volts DC) you need ANL or Class T Fuse. PROwatt SW 600 = 80 Amp, PROwatt SW 1000 = 150 Amp, and PROwatt SW 2000 = 250 Amp.

need 20 amps . Not sure on inverter . And you need a heavy.duty extension if you use one.

Yes, #4 will easily handle a 500W inverter. You could use smaller, 6 or even 8 if you keep the length short. I have this kit on my 1500 watt inverter.

The directions that come with the solar controller tells you. Basically, they should be as short as possible, 2 feet max.Next, AWG should be 6 or 8. That comes right out of the owners manual which you should have received with the unit.

I have 2 panels, each puts out about 7 amps connected to this controller and could easily add more. Look at the specs on your panels and size your controller appropriately.
