Multiple solar edge inverters

Hello,

I have two single phase HD-wave solar edge inverters and one Multieplus 2 GX.

Network:
All systems are connected to the same homenetwork and both PV inverters have the same Sunspec setting from Integrating with SolarEdge [Victron Energy].

Electrical connections:
The first PV inverter is connected to L1 output from the Victron multiplus 2 GX and works perfectly.
The second PV inverter is just grid connected to L2 without any Victron devices.

I have added both PV inverters in the GX device via the separate IP addresses which I have fixed for the PV inverters.

The problem I have is that the second inverter has an unstable connection → the data keeps dropping out and restoring itself after a couple minutes.

I have tried to change the TCP port and device ID in the solar edge inverters but then the datastream stops working completely.
Both PV inverters and Multiplus have the latest firmware.

Do I have to interconnect the inverters with the RS485 although they are on different electrical systems or did I mis changing a different (adres) setting?

Thanks in advance!
Dennis

P.s. also there’s is a fault in the Victron “Integrating with Solar Edge” document as the K1 output (as it’s directly connected in figure 5 - page 4) is not suited to “Switch” the Solar edge (+5Vdc to L1 as shown in figure 4 on page 5) from the normal grid code to the APS (alternative power source) mode
The fix is to rewire and -program the Victron and use the Primary AUX relay output.
(Or use a second relays which would be switched/powered by K1.)

Where can I send this feedback to improve the curent docu?

Nevertheless props to Victron for making this awsome device with all the options and freedom!
