    I have just bought a 5000 watt peak inverter . I am fitting it in my prime mover to run a microwave and toaster. It has 2 positive and 2 negative input terminals. Can anyone explain why. It is a modified sine wave. Nothing in the manual mentions anything about the terminals. Not really a boat question but boats use inverters as well.

    At peak load the inverter draws more than 400 Amps @ 12 VDC.
    I'm not surprised there are dual inputs!

    Thanks . Why not just have 2 terminals and larger leads.

    5000 Watts is quite rare for 12V inverters, so the production quantity is too small to purchase heavy leads and terminals.
    But they should have mentioned it in their manual.

    Thanks cdk. 5000 is the peak. Continuous is 2500. I will run the truck engine when I use it and I have a battery bank of 4 n120 batterys so it will have a good 12v supply.

    Plus it is a convenient DC distribution point. You can daisy chain your DC to other stuff without a monstrous bus bar. Really fat wires in one terminal, a fat wire out the other to a fused, modestly sized bus bar and out to the rest of you boat.

    Check to see if there is a passthrough current listed on the specs.
