    Thanks! I made the changes, now I just need some sun to test it out. Maybe in the Spring HAHA
  • Post in thread: Seeking help with Growatt/BigBattery settings

    For me is was just stupid simple. The ground lug on the Growatt was not connected to a ground wire that was actually attached to my ground rods. But there are still some glitches I am working out. Having now worked with several other systems, I am 99% convinced I would go with a Solarc when I...

    For $18 I'll give it a shot! Thanks

    So I stumbled on the issue after talking to an electrician friend. Turns out it had nothing to do with programming and was caused by an incorrect bond out to the ground rod.
  • Post in thread: Voltage detector for starting and stopping generator

    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...

    Thank you for the input. I can now see how cryptic the Growatt setting are if you are not looking at the manual. Hopefully these make a little more sense. The battery does have its own built in balance function, if that is what you are referring to as an active balancer. The digital display on...
  • Post in thread: Generac Eco-Gen 15kW (2020) to Growatt 12kW -> 2-wire-start-stop dry contact problem

    I have a similar setup with a growatt 6K and Generac gen. To start with, in my opinion , setting 12 can’t be set high enough and lets the battery get way too low before closing the contact, 51.2 is the lowest setting and it closes the contact closer to 48 which is the max setting for the low DC...

    Very easy to set up. The inverter is the SPF 6000T-DVM-MPV. My house came with a Outback system with an entire wall of components and a lead acid battery bank that took up half the room. I now have only the Growatt inverter on the wall and Rhino battery on the wall below it that only sticks out...
  • Post in thread: Seeking help with Growatt/BigBattery settings

    I will have to check next time I am at a full charge to confirm the voltage. I am seeing the same voltage on every cell at every other state of charge. Regarding communication, I am not sure what port the cable would go in and what the correct address/protocol would be. On the inverter I know it...
  • Post in thread: Seeking help with Growatt/BigBattery settings

    Hello, being somewhat of an amateur, I am looking for some feedback on properly setting up my system. It is working but could probably be better. I do have one issue that is when the battery if full the inverter will shut off. My assumption is that it has something to do with settings and the...
