Hello everyone. You just need to try. It won't flash with incompatible firmware.

F17 for ultra model the update firmware
Suntex service

Axpert_ultra_11K_ver 25.68.7z

I wanted to throw away the Wi-Fi and just connect the Solar Vampir instead. But it has a different protocol than the MAX II. I'm currently talking to the Vampir admin. I want to get this whole thing working.

Yes, I also monitor Solarassistent. But now it can connect to the inverter via Wi-Fi. But it doesn't connect to this one. But it does connect to the Voltronic MAX II 11000W. And I want to install a Solar Vampir, too, and I need another RS-232 port. Now I'm wondering how to solve this.

Yes, try it. I had the same firmware as you. I had to dance with a tambourine near the inverter. I re-flashed it and forgot about it. One DSP 25.09 didn't work. It also started throwing errors with my settings. I reverted it back and forgot about it. I just wanted to research the firmware and choose a good one. Now I'm on 25.11 and everything is fine.

Hi. I had the same problem with these firmware versions. And the representatives couldn't provide me with anything. Try updating to the new version. The latest one. It worked for me. It works without any issues.

Initially, I had version 25_07. The operating logic wasn't bad. It was really bad. Then I found version 25_74 on the EVA forum. It worked fine. Then they posted version 25_10 on this forum. It also works perfectly. No complaints so far. But then they posted another version, 25_09. So I decided to give it a try. It turned out that it's even worse than version 25_07. At the slightest load, it throws an F17 error. There's a large imbalance in the DC voltage. This is with all my settings. I reverted back to 25_10. It's working fine so far, without any problems or errors.

I'm thinking about replacing them. Preferably, everything near the power supplies. Or at least measure them with an ESR tester.

I give the sun performance a 3. Compared to the 64.62 firmware for 90 volts. I liked it. But the display firmware is completely raw. Can anyone help?

I also thought about what the place for the accumulator is for. One thing comes to mind. There should be a real-time clock chip PFC 8563T and all the rest of the harness there. But all this is already on the display.
