Smirresa Posted December 4, 2020 Share Posted December 4, 2020 I have 2 x 5kVA Axpert MKS II inverters in parallel with 24 x 380W panels (9120W total), 8 x Pylontech 3,5kWh batteries and a Raspberri PI with ICC installed, controlling the system. Last couple of days have been cloudy with intermittent periods of full sun and I am now periodically logging very high (20,000 - 30,000 W) outputs from my solar panels on the PI. Happens in the morning around 9 ish when the sun is breaking through the clouds. Looks to me like a measuring error somewhere as the reported values are 2 - 3 times the installed PV capacity. Anybody seen this before? Quote Link to comment Share on other sites More sharing options...

My guess is that command responses are getting corrupted. It's tricky guessing how much time to allow between commands; too much and you miss out on fine changes in data, too little and you get occasional corruption. I have no idea whether you can control that time with ICC. Another possibility is that your comms card has marginal opto-isolators on it. You could try replacing with better-spec'd parts, or replacing the comms card. Since you have two Axperts, you could try swapping comms cards, or simply plugging ICC into the other inverter should work. Quote Link to comment Share on other sites More sharing options...
Smirresa Posted December 7, 2020 Author Share Posted December 7, 2020 Thanks @Coulomb, will try the swap first Quote Link to comment Share on other sites More sharing options...
