HOYMILES
According to Hoymiles, the inverters have a: Derating triggering temperature of 85°C Derating factor of 14% Shutdown temperature of 90°C Restart temperature of 85°C Restart interval of 0 (meaning that, once it shuts down, a Hoymiles inverter will continually check to see if it has reached the required restart temperature, allowing the inverter to begin converting power as fast as possible)
The graph below shows the power reduction relative to the temperature of these models of Hoymiles microinverters. As you can see, power drops rapidly once the internal temperature of the microinverter rises past 90°C.
However, once the inverter reaches the restart temperature of 85°C once more, you can see that the power immediately rises back up to 100% — no waiting around for the power to gradually rebuild once the inverter restarts.
(to be translated) Es müssen alle Gehäuseteile der Anlage auf eine Erdungsschiene geführt werden, sowie die Erdungsanschlüsse der Überspannungsableiter. Beim Hoymiles Wechselrichter gibts auch eine Schraube für die Erdung. Die Erdungsschiene wird dann mit der Erdung verbunden, im Haus wäre das die Potentialausgleichsschiene. Die Plus- und Minuspole sowohl der Batterie/Akku als auch der Solar-Panel-Leitungen werden nicht geerdet - sie sollen potentialfrei sein!
All housing parts of the system must be connected to an earthing bar, as well as the earthing connections of the surge arresters. The Hoymiles inverter also has a screw for earthing. The earthing bar is then connected to the earthing, in the house this would be the potential equalisation bar. The positive and negative poles of both the battery and the solar panel cables are not earthed - they should be potential-free!
