So I bought and installed an inverter in my RV, whose main and remote power switch is a "momentary soft latching tactile button type, press 2 sec on press 2 sec off.
The problem is I want to wire in a programmable 12v power cutoff relay, that is either closed or open.
What is the simplest way to get it to control the inverter on/off, and keep an override switch? Relay switching the power wont work because the inverter always starts "off" when powered.
There are four wires going to the remote switch in an RJ11 wire. I'm hoping two of these will work as normal mechanical contact or no contact open/closed on off that I can route through a relay(?) The remote switch button itself is a small box with circuitry inside, I'm also hoping the mosfet or whatever that works as the soft latch circuit is contained in there, not in the inverter board itself.
The only info that I found that may apply says that one pin is 12v, one, "the switch" is a 5v. I'm not sure if this applies to mine:
"For APS remote jack: Pins 1 & 6 are unused. P2 is LED, P3 is +12V, P4 is Ground, P5 is the SWITCH.
Pin 5 has a constant low. A 5V pulse turns unit on/off.
I was a bit confused about 5V puls part, as there was no 5V voltage on the inverter. I tried sending 5V from external source (with tied grounds) and nothing happened. In the end I touched together pin 5 and 3 and it worked. Trick is physical switch has to be ON. There's actually 5V on Pin 3 when it's in standby..."
To have a manual overide on/off switch, where would that go in the overall circuit?
Or should I just find another inverter with a toggle switch?
