I have a Growatt SPF 6000T DVM-MPV off-grid inverter. I have been struggling with the dry contacts for generator start, as soon as the contact closes it immediately opens the contact when the generator comes online. I was finally able to get a response from Growatt Support:
"Unfortunately, there is a known issue with the dry contact logic for our DVM inverters that turns the generator off when AC input voltage is detected. There is not currently a fix. I have read in forums of installers using voltage sensing devices in place of dry contact terminals."
So here I am, any suggestions on what to use for a voltage detector that can open and close a relay based on a low and high set voltage for a 48V system?
