Hi,
I've found the connector for remote control of the inverter, terminal L in manual, where I can set the state of the Quattro remotely. But I'm trying to find a way to also show the state remotely. Is there a clever way to get an LED to light up on a remote cable when the inverter is on?
Background:
I'm building a remote control for the Quattro on my boat and is looking to build a three-state-switch on the control panel of the boat. As it is an old boat I want to hide as much tech as possible. I'm looking to make the states of the switch off-auto-on, so that if I set the state to off it will not turn on inverter, in auto it will turn on whenever I have either more than 90% battery or the batteries are charging and in on it will turn on the inverter.
I have figured out how to do most of these things. I'll use the L-terminal to remotely control the inverter and I'll probably write a small python script which will close the relay on the Color Control GX whenever I'm charging or have more than 90% charge so that in the auto-position of the switch it uses the relay as switch. The thing which is left is to indicate the state. I want to show with an LED next to the switch if the inverter is running. Currently the only ideas I have is either to hide a 5V USB power supply in the inverter, connected to the AC out which will supply power whenever it is on, or to hack the LED on the Quattro and solder an extra cable onto that inveter-on-LED-indicator.
Ideas welcome!
