@LionKing were you able to resolve the issue, maybe able to reset something? I have a 3KW infini and since about a week ago the daily generation on the inverter itself does not reset overnight anymore like it used to do in the past. Lately when I check the inverter in the morning before sunrise, it already displays a daily generation of anything between 5 and 15 kW, sometimes more, sometimes less. During the day the generation increases as expected, it just doesn't reset (at midnight) like it used to. I powered down the inverter to hopefully "reset/restart" everything, but that did not solve the problem. Ps. I'm not running any monitoring software, so I don't really know if it actually resets at midnight and then maybe generates power from the moonlight perhaps. 😁 Guess I'll have to monitor it to know what exactly happens, but that is not a priority right now while the inverter is still running fine... Any other suggestions, maybe to reset something?

Apologies. For some reason I didn't get any notifications about posts on this thread and only saw your question today. The monitor was sold on 28 Aug.

Cannot say for sure. Just noticed that one reviewer on that product page mentioned that the cable does not work on Windows 11...

Yes, it will probably work for any battery with a RS232 (serial) port. You'll just have to verify the pinouts on the battery's serial port, because it might be different.

Only 1.5 years later, but I was also looking for a cheaper cable solution to connect my Hubble AM2 to my PC, and was unable to find proper instructions to construct my own cable, so I did some research and decided to publish a working solution here. You basically need any type of USB to TTL (serial) converter using the FTDI FT232R chip. There are many options available locally, but the most popular options are the cable version, where the chip is inside the USB connector, and the module with an on-board USB mini or type-C connector. The modules cost around R40 at the time of writing (https://make.net.za/product/4me3303/) or (https://www.communica.co.za/products/hkd-ft232rl-usb-to-serial-board?variant=50139935736108). Just make sure you get one with an original FTDI chip, because there is some issue between the cloned chip and the drivers. You can download the driver from https://ftdichip.com/drivers/ The Hubble has a standard RS232 port (-15v/+15V) and the USB to TTL converter or cable provides TTL levels (0V/5V), so you need a level shifter in-between. Fortunately that is also readily available locally at around R12 at the time of writing. (https://www.robotics.org.za/MX3232-MOD) or (https://www.diyelectronics.co.za/store/serial/638-max3232-rs-232-ttl-uart-serial-module-level-shifter.html) Now you just have to check the pinouts on your USB to TTL converter cable or module and verify the orientation of the level converter module (marked with RS232 <-> TTL on the one side of the board) to ensure that you are connecting the 5V, GND, RX and TX pins to the correct end of the level shifter board. Then connect the GND, <- (IN) and -> (OUT) pins on the opposite end of the level shifter board to PINS 2, 3 and 4 of the RJ12 connecter and you're done. Refer to the attached images which clearly shows all the connections.

Have you had any luck resolving the problem? I have 2 of the OG5.48 inverters, one about a year old and quiet, but my new one which I have for about 1 month now and which I've only started up yesterday has this high pitched noise as soon as grid power is connected. When it is running from battery it is quiet.

Now Nersa wants to charge you if you are generating your own power - generators, solar etc. etc. - connected to the grid or not. What a lot of BS. https://businesstech.co.za/news/energy/205382/you-may-soon-need-to-register-and-pay-nersa-for-your-personal-generators-and-solar-panels/
