Morning All I have 3 of these Five Star 8K invertors in parallel as in the picture and are also struggling to communicate with it with ICM. I have the Wi-Fi Dongle and that is great just for monitoring but serve no help when it comes to power management. Any idea or work arounds on how to make it work or any other power management systems that would work with this invertor. I have tried both USB-printer port and USB-serial port with various of cables bought but it seems that the raspberry pi does not want to recognize the cable or retrieve the data. As said with the Wi-Fi dongle the data is visible which assures me that the RS232 port is work. The invertor does not have a RJ45 port to connect USB-RJ45

Thank you, will start doing that.

Good morning, all. Need some help. I have three 5kw Axpert Invertors making up a 15kw parallel setup. 2 of are connected to 9x325watt panels and one is connected to 12x325watt panels making it a total of 30x325watt = 9.75kw. This setup has been running for over 2.5 years producing on average 7kw and has gone up as high as 9kw. But as of late i'm struggling to see 5kw from the PV. I have looked for damaged or burn marks, i have washed my panels to no success. If i measure at the invertors it still gives me the 118V input as the panels are rated 38.8V but the string of panels only generated highest lately 1.5kw as displayed on invertor. What else could be the problem

Thank you for your input. Yes busy with the identification of the sources of load during high sessions and seeing if I can spread it or illuminate it by buying lower energy consumers. Geysers are already on timers to cater for draw during solar peaks for now will later go to dedicated solar panels for the geyser and 48v elements. I understand the drop during low load demand but there is some blips were it just drops to zero which I can not find a reason for.

Good Morning All Thank you for allowing me to join the forum. I have a new installation of 3 x 5Kw Axpert Invertors, 30 x 325w panels and currently 12 x 200Amp/12v Gel/Acid batteries. The setup works quite well, although I will have to upgrade on the batteries soonest also some more panels as the split currently over the invertors is 9/9/12 and would like to balance the spread. The question that I have is, having monitored the system for a month now is that I see the PV falling away in sudden incidents during the day. I'm not talking about dropping when load is low but falling to zero. Comments welcome, I'm still learning a lot.
