Volatile memory was a pet peeve of mine with the Trace SW inverters. I quit even trying to program them, because they would always end up getting reset anyway. However, I've tested this feature on the Midnite Classics and I could not get them to drop programming. I used the computer app, set

All CC's have their problems and MidNite has had their share, but losing or forgetting their programming has not been one of them that I'm aware of. If it is a standard Classic with MNGP display, don't forget to press ENTER after setting parameters so that the Classic remembers those setting

Has anyone had an issue with Midnite solar Charge controllers loosing programming. I have had Out back FM 80 do this and it was an software issue they fixed it. Now I have the same thing with midnite either that or the customer is messing with it and this is also a good possibility but before I go

I'm a Generac service tech and have some experience installing gaseous generators (their term). I don't have any experience with freezing, being in the Caribbean. Virtually every installation not designed by a tech will have fuel piping that is too small. The 20KW Generac Guardian needs a minimum 3

Thanks for the feedback. Turned out to be 3 separate issues. The AC backfeed turned out to be mostly caused by a missing neutral to ground bond. With that corrected, the backfeed dropped from 30 volts to 2 volts on one leg only... still a puzzle. Other issues were a snow and ice covered reg

Alot of these generator setups need 2 regulators, so usually the regular one stays at the tank, size the pipe for the flow rate ( just like wire and amps;-) .) and put the 2nd regulator right at the generator. R.Ray Walters CTO, Solarray, Inc Nabcep Certified PV Installer, Licensed Master E

Ditto Tom, seen this too often in Mexico. I carry a manometer to make check the pressure at the LP input to the generator with the engine running. Make sure it is at/above 11" WC when it starts to act up. If the regulator is at the tank, long vapor runs can cause too much pressure loss. Larry

If you disconnect the leads to the Benny from at the inverter do you still have this condition. I had a battery charged supply (ac) in the same conduit as the remote start and the transient voltage would be enough to signal z start up. Your issue is a little different but it might still be transien

If you are using Sketchup for solar, you should be using the Skelion plugin. It will compute and draw the solar modules on any surface based on your preferred module, tilt angle and azimuth. We do all our quotes this way. ___ List sponsored by Home Power
