    Hi Guys,
    I want to measure the AC amperage from my inverter using a standard analogue panel meter to see what is being drawn from it at any time.
    Can someone advise me how to wire this into the circuit? when I wired it directly to to the power and neutral terminals it just flipped up to max (20amps) and tripped the fuse ooops... my DC amp panel meter works fine from the solar panel wired directly to the positive and earth terminals. Is there another component I need between the circuit and the panel meter for the AC side?

    Tony, When mesuring ac amps with a multimeter it normally clamps around the hot leg of the circuit. I would look at your wiring diagram that came with your amp meter.If it is used and you do not have a diagram my best guess would be to take the hot wire and put it to one terminal of the meter and attach the hot wire load to the other terminal.I would put a 1 amp fuse in the circuit and use a 100 watt light bulb for a load and test it with house current to not damage your inverter.It should draw close to 1 amp.When you put the hot and netural on the meter it made a direct short causing your fuse to blow an may have damaged the meter. Good luck Mark

    Tony, This is an after thought.When I said that the meter should read about an amp that was at 120 volts. I forget that the internet is larger then the United States.At 240 volts it would be about 1/2 an amp. Mark
