We have an Xantrex XW 6048 inverter we installed for a client about 2 years ago that includes the separate generator control module, which currently programmed to start the generator on low battery. The client has gone through several outages when he was not home. The solar/battery/inverter system worked too good so the battery charge never dropped low enough to start the generator, so the heat never came on. His heat will never run during a winter outage unless the generator is started.
I know the XW generator control module has a specific control input dedicated (yellow & gray spares) for a remote thermostat that will trigger the generator to run if the thermostat calls for heat. I also changed the program switch enable the thermostat input function (default is off). However, this feature does not work. We even shorted the control wires right at the generator control module but the generator will not remote start except using the remote display manual off/auto/run program toggle, which at least shows this generator control module does work. The installation manual states it will start the generator on a "signal" from a wall thermostat. Does this mean we need a voltage and not a dry contact? Any suggestions?? Thanks, Jeff Yago
