Understanding inverter startup voltage. | DIY Solar Power Forum
Meaning that each individual string has to be of a certain size to reach the inverter start up voltage separately. For example; inverter start up voltage 90v. So each string has to be above this voltage separately or does the whole array work to achieve this startup voltage independent of the amount of strings?

If your CC shows full panel voltage but no current is flowing then your CC isn''t applying a load. Its possible to have full panel voltage with an open circuit and a poor
PVOutput shows unusual dip to zero power
The optimizers report the instantaneous output of the panel, but do so on irregular intervals. I have seen the PVOutput data show a brief drop to zero power. The latest one just happened 45 minutes ago (2017-08-28 11:15am): The individual panels do not seem to show any issues. The inverter, however... 2017-08-28-Inverter-Iac-Vdc.png
How does an inverter synchronise to a generator
On a LF AIO inverter PV power is converted directly down to battery so it can charge battery without inverter operation. It does need inverter to convert PV power to AC output power. AC input charging on LF inverter goes through inverter to battery. View attachment 128067
