We will be installing a Quattro 48V/10K sometime soon, and would like to have it autostart a small Duromax XP12000EH generator. That generator uses a typical car-like starting system, with a keyswitch (that I'll tap into) that has Off/On/Start-momentary. Looks like this
- Off : two sets of wires are jumped. Easy enough to do with an extra double-pole relay. These ground out the coil, and open the fuel solenoid.
- On : nothing is connected.
- Start : Just like a car, momentary jump of two wires until gen is running, maybe 2-3 secs
I see lots of posts about using special generator control modules ($$) or timed relays etc. There must a way to use the programmable relay assistants to handle this. @Mark gave a really nice description in
that it should be possible using two relays, programmable primary, and secondary K1. (I want to use K2 for a vent fan in the battery box ...)
The logic would look something like this I think :
Quattro determines that gen should start (battery SOC/Volts AND no grid AC)
- Close primary relay. Hold in this condition as long as gen should run.
- Wait 1 second
- Close K1 relay
- Wait 3 seconds
- Open K1 relay
Quattro determines that gen should stop (battery SOC/Volts OR grid AC good)
- Open main relay
How could we implement this with Assistants etc ?
