Hi Derrick, sad to say no. It needs a serial port to connect to PC. Cable came with inverter but to find a pc that still has a serial port that has not been converted to a media port is not easy. Apparently there is a company in JHB who can do the update, but then Ill have to box it and courier up and down. So as I'm using my system as a UPS anyway I decided to rather buy a new inverter sometime in the future. Good luck, its very frustrating.

I had another lov voltage alarm this morning so made some small tweaks, but am now ready for the update. PF0.8 as I can figure out.? Thanks

Sticker on side. Will add 2 more pics , but I think its an PF0.8 (2015)

Changed 29 to 45.5v Instantly fixed the alarm problem. Will see if I can update the software. Ps. RCT inverter RCT-AXPERT 5K

Just got a low voltage alarm (04) at 49.7v What did I do wrong?

Thanks for advice, guess Ill have to save up for bigger battery. I guess I could add a Pylontech US3000 3.5kWh 48V Li-Ion to my current Pylontech US2000 2.4kWh 48V Li-Ion with no problems???

Thanks for the inputs. The system was supposed to just help us through load shedding, but runs our small house for about 5 hours. After I took many power reduction strategies. So I get a similar output as when I had 4 x 105Ah batteries, but without the hassle. In hind sight I should have gone for the 2.5 Battery, but it always feels like a lot of money if one is not that sure. I found a lot of solar companies are happy to sell, but then never want to hear from you again. This information provided is like gold to a beginner like me. Thanks

Thanks so much. Yes im starting off, saving up for improvements later. I will use your suggestions and report back.

Feeling like a toddler in a A380 cockpit trying to land in a driveway. I have the following settings, will this work or have I programmed it to self-destruct our little village? Please help. I would like the panels to charge the battery to full then use it, utility to kick in when heavy equipment kicks in.
