I now have Solar Assistant up and running. Love it! Better than the Shine app (when it worked for me).

I am trying to get my system back online so I can monitor what's happening WRT solar production, solar charging, utility charging, utility bypass, battery SOC, etc. Very important to me so I can time when I charge my EV from the off-grid system and when from the utility. I am trying to make...

I changed out the board and the inverter came back online. Now I need to get the WiFi dongle to speak to the inverter so I can see the status of the system via the app and online. I'm in the middle of trying to write the inverter SN to the new controller board, per Growatt's instruction. Not...

@BenFromSignatureSolar Looks like you hooked someone else up with the assistance I need to change out the control board on my SPF6000T DVM-MPV. It bricked after an attempted firmware update. Sig Solar already sent me a control board and I am ready to install it.

I saw a picture of someone opening the unit and had the same thought. Looks like there’s a ribbon cable to the controls/display on the front. Anyone out there know of a video or post with pics showing the procedure for replacement?

After a number of calls and submitting a video of the current state of affairs to signature solar they were going to take back the unit and send me a new one. But the hassle of taking this hundred pound unit off the wall and shipping it back to them seemed greater than the trouble it might take...

Do you usually get responses quickly? I emailed this morning (I'm on Eastern time).

Not at all. I installed the driver for the ISP tool and the PC recognized the inverter. I unzipped and, using the ISP tool, browsed for the bin file that was in the folder you linked to and flashed the inverter. It shut down and the CHG light came on as the instructions stated it would. And...

Do you have nay other contact info?

@Pete@SolarBatteryBarn: Unfortunately this firmware update did not take and now my inverter is dead. I will reach out to Francis Liang for support. Are they stateside or in china?

I now I wished I’d gotten the 8K model. As of now when I’m charging the EV the wife can’t make tea with the electric tea kettle without causing a fault. Because my kitchen has got a couple of multi-wire branch circuits I had to move more over to the off-grid system than I originally planned.

@Pete@SolarBatteryBarn I still get those data spikes. How do you update the firmware and where do you get it?

The utilities are in it to make money, and they are trying to maximize that. There are reasonable arguments that say managing the unpredictable ebbs and flows of all us small guys feeding the grid makes it harder, and that the grid is expensive to maintain to begin with. You ask me, it should...

You will need way more panels than you can fit on your truck, unless your work day’s a week long. ?

If 50 kW they are likely DC fast chargers.
