Running DEYE inverter (SUN-8K-SG01LP1-US) no grid connection, no battery, 1 strand of 7 x 455 watt solar panels in series.
Was cloudy today, PV input voltage according to the inverter was about 340V @ 0.1 amps during the day.
So that's 34 watts, apparently not enough to kickstart the inverter.
3 questions:
1. Is it normal for this many large solar panels to only generate 34 watts output on a cloudy day, or does it sound like I've done something wrong?
2. Normally for these "all-in-one" inverters running with grid or battery, what is the minimum PV voltage and/or watts required from the solar panels to get the inverter to "wake up" and start making AC?
3. The datasheet for this inverter says "Start-up Voltage (V) = 125"

What is "starting up" with 125V? It means I can charge start charging a battery (when I get one) if the PV input is > 125V? It means the LED panel on the inverter will "wake up" with 120V PV input? It means it should be able to start making AC with 125V PV input?
