Still running ye olde Prosine 2.0 with it's reconstituted remote display. I still have a problem though: after a random length of time, between an hour and several days, the display changes to an error report, seems to be about a communications problem. The inverter is still running OK, and the LEDs in the display still function, but the LCD only displays the error message. If I turn the inverter off and back on it returns to normal, for a while. I've written Xantrex about this, a few years back, and they more or less shrugged, saying it happens sometimes, there's nothing they can do about it, etc. Is there really no fix for this?
