Charger input #22

I have put together a new battery rack for my motorhome using pre-charge, positive and negative contactors which doesn't seem to be supported by ESS mode.

How about a mode where you activate the charger input, but not the run key; where it does the standard startup process of the Negative contactor, pre-charge and then positive contactor plus equalization?

Thanks

Some other thoughts:

  1. Contactor test code: Have it activate one line at a time and output message as to which line is being activated.
  2. Startup: It currently turns on the negative contactor and pre-charge contactor simultaneously. It might be easier to diagnose problems and check functionality if there was a delay between the negative and pre-charge. So you could observe a startup sequence or hear the relays clicking or get tactile feedback via your finger tips.
