Guys, I have been using Solar Assistant since early 2020 just before the dreaded big-C hit us. Check out their web page at : https://solar-assistant.io/. I'm not affiliated with them in any way, this is just a better solution for what's out there. Many different systems are natively supported. I used the same RP model 3 which I previously used for ICM. There is allot of features, dashboards and more. You can also integrate into Home Assistant with MQTT. You can even control your inverter from the App and it supports load shedding schedules to ensure your batteries are at the level you require before load shedding hits. I don't use my Sunsynk inverter's native app as it does not give me as much control and overview as Solar Assistant does and Solar Assistant is almost real time, maybe 3-5 seconds behind what is actually happening with your system. This is just may way of thanking the team for a great product. Hope it will assist you all. Regards,

Hi Grthox, Not sure about Voc etc but I do know the panels are wired in three strings. I will try to lookup the panel specs. All I know they are JA Solar 320W monocrystalline panels with all black frames. That's as far as I know. Will this impact the maximum charge and discharge currents limits? Sorry I'm just a user and nowhere technically inclined with regards to this subject matter. My fear is just that with the experience with the Deye inverter they told me the charged and discharge currents were too high. I therefore replaced it with the Sunsynk and settings as per my installer should be the same? Regards, Rudie Found the pdf for the panels as attched. JA SOLAR PANELS.pdf

Hi Guys, Not sure if I may continue on this thread? Please advise if not. Anyway, I have a 8 kW Sunsynk single phase inverter and seven Pylontech US3000 batteries and 24 x 320W panels. What is the maximum charge and discharge currents supposed to be? Is it correct to calculate 7 x 37A = 259A? If that is correct, what is the safest Amps for the inverter and batteries because this seems very high to me? I replaced a Deye inverter with this Sunsynk and the feedback I got was that the Deye had over current faults which caused it to blow up the CB's. Your kind assistance will be much appreciated! Regards, Rudie

Replace ICC with Solar Assistant. It runs on your Raspberry PI. Check: https://solar-assistant.io/

Hi @Youda and @Jaco de Jongh, Thank you for the feedback. @Youda I have confirmed with regards to your point 3 made above. I have turned of the slave inverter (which is the one running at full / over capacity) and the power stays on. The Master unit then takes over seamlessly. As soon as I turn on the Slave unit, it reverts back to the previous state where it can audibly heard working harder and produces more much more AC output than the Master unit. Please refer to the pictures of the installation. I further note that the firmware is on v1. Could this make a difference and if so, where do I get new firmware?

Good day to all, I'm new to solar and recently had a solar power system installed. I have 2 x Infinisolar Super 4 KW inverters, 4 x Pylontech US3000 LiItheum batteries. There are 24 x 320W PV panels mounted on my roof in 2 arrays of 12 each connected to each inverter. I have 2 PI's running the latest ICC software connected to each inverter and configured by ICC remotely. The installer and I have checked to ensure that the parallel communication cables and current sharing cables are installed correct. To this end we have studied the manuals and this and other forums to make sure that the installation is 100% correct. My problem is that the Slave inverter runs at almost full capacity whereas the Master inverter runs at 2 - 3% capacity in terms of AC output. How do I get the inverters to produce more or less the same AC output? I do not have SNMP or Modbus cards installed in the inverters. Could this be to the incorrect start-up procedure? Does someone have the correct startup procedure or is the problem something else?
