Note that the IRF2804PBF is an N-MOSFET so it needs to be wired upside down from the circuit you show in post #7 [gate to (+) line, drain to (-) power, and source to (-) inverter connection].
Bummer. I just now finished this Visio drawing. You are saying that it is incorrect here.Note that the IRF2804PBF is an N-MOSFET so it needs to be wired upside down from the circuit you show in post #7 [gate to (+) line, drain to (-) power, and source to (-) inverter connection].
Okay. Would the following be correct?Note that the IRF2804PBF is an N-MOSFET so it needs to be wired upside down from the circuit you show in post #7 [gate to (+) line, drain to (-) power, and source to (-) inverter connection].
THANK YOU! FANTASTIC!
Have you priced an 80 amp, continuous duty "simple Contactor"?Why dont you use a simple Contactor with a Diode that energises only on the correct polarity?
Have you seen how simple the setup is ?Have you priced an 80 amp, continuous duty "simple Contactor"?
Hi crutschow, Can I expect any significant current through the gate? My guess is that I won't, but I thought I'd check before I start wiring things up.
A MOSFET gate looks like a capacitor, so the current is essentially zero, only a very small leakage current as given in the data sheet (200nA for the IRF2804PBF.)Hi crutschow, Can I expect any significant current through the gate?

That makes sense to me. Thanks.A MOSFET gate looks like a capacitor, so the current is essentially zero, only a very small leakage current as given in the data sheet (200nA for the IRF2804PBF.)
