Adding a third party inverter (SOLIS) to a SMA system

[SomeGoodBits]

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.

I seem to remember that SMA did not allow much end user intervention. This may have changed in the last decade or so.

 

Can you fudge/trick the system by getting a CT clamp (I assume it used one to monitor power flow) to sense the two inverter wires together?

You’ll like need to lose the sunny home manager to do what you want to do.

 

I have a sunny boy sb4000 as my solar inverter, and Solis ac connected inverter for the battery, the Solis manages what goes in and out and when it happens, you wouldn’t need the home manager.

 

hope it helps, see my blog posts on my system maybe they will help too
