The insurance dictated the inverter - 9 nine years on from the original kit. Maybe i am naive but shouldn't stuff get better?

Thanks guys, i actually solved the problem by putting both the SMA inverter and the SOLIS inverter throught the SMA energy meter. The sunny portal knows what the Sunny boy is producing so i can see both inverters on the analysis graphs - great. I was very pleased for a couple on months. Now the weather is getting better output is up, and the SOLIS inverter does not seem to like it, we keep getting over voltage alarms. I suspect the SOLIS inverter is competing with the SMA inverter to export to the grid. SOLIS support are very helpful, but not particulary capeable. Will keep on, maybe i will put my TL5000 inverter back now the insurance job is all done. Any ideas on taming the SOLIS inverter would be apreciated.

I guess JamesPa has moved on, and i am sure he has seen the document from SMA that i am uploading. But i had to upload it when i saw this topic, it guided my choices. 7 reasons to undersize.pdf

I installed two arrays of solar panels manufactured by a company called FranceWatts totaling 10.5Kw. I had two SMA Sunny boy inverters a TL4000 and a TL5000. I also installed battery backup with a sunny island 6.0H and i build automatic transfer switch myself. I recently lost a 6Kw array due to storms, however the insurance paid for a new installation, which i gladly let some professionals do. This will enable me to sell surplus electric to EDF, which i could not do before with a DIY setup. Unfortunately i have had to accept a SOLIS S-GR1P6K inverter, this i am having trouble integrating with the SMA sunny portal. I have the SMA Home Manager 2.0 (SHM2) and a SMA Energy meter20. I theory the energy monitors the input to the system from the Solis inverter and the SMA sunny portal uses the SHM2 to manage the whole system. I have followed all the information SMA provide. I have attached that documentation. The problem appears to be that while the energy meter is used to monitor the SOLIS inverter power, the power from the SMA TL4000 does not get included in the total power generated. The TL4000 power can be seen in other areas of the sunny portal. For obvious reasons i need the the total power to show so i can manage loads and grid feed in. Have i explained this clearly? I have spent hours trying to sus this. Third party integration.pdf Setup of Energy meter in SHM2.pdf Sunny portal screen shots.pdf
