Dear forum users,
first of all, please excuse me if I do not speak German, but this is the only forum I have found on the subject.
We have 11 Piko 10.1 Dcs inverters with firmware 3.70 + 1 Piko 4.2 Dcs inverter with firmware 3.60 that were added to the piko-solar-portal.com monitoring portal on 20/04/2019 using a new account.
All inverters are connected to the internet via a switch and a router that allows any outgoing connection so, the monitoring server http://www.pikoloop.de is correctly reachable and the message "PIKO Server, v220.127.116.11" is displayed on a client pc.
From the internal inverter webserver I have specified an unique ip address for each inverter, the router ip address on the gateway field an made various test using different dns from Opens dns, Google and the standard 18.104.22.168 dns.
After entering the portal code P3421 all inverter were successfully added to the portal by entering the corresponding item number and serial number: this seems to mean that tcp/ip connectivity with the portal has been established successfully.
The problem is that no inverter has ever transmitted monitoring data and the history of the piko-solar-portal.com portal is empty even after the “go online” command.
Any help would be much appreciated.
