[RE-wrenches] Remote Alert and Bootstrapping on Sunny Island AC Coupled System-Follow up

[William Miller]

Wrenches:



I found some time to review the .evt and .log files from the primary Sunny
Island inverter.



Prior to 12/8/20 the system was running normally with a generator run
averaging 6 hours about every other day.



On 12/8 at 06:00 the system tried to start the generator.  There was no
indication the generator delivered voltage to the system.  The system tried
to start the generator 168 times between 12/18 at 06:00 and 12/13 at
15:00.  168 times the system closed relay 1 and then opened it about 2
minutes later.  Maybe the generator ran, maybe it didn’t, but no voltage
was delivered.  On 12/15 the client started the generator and it produced
voltage into the inverter system.  On 12/18 I started the generator and it
produced voltage.



Why this generator start cycle kept recurring is a mystery to me.  There
may be a setting within the bowels of the menu system that I have
overlooked that limits the start attempts and I will be investigating
that.  To me, navigating the Sunny Island menu system is like trying to
remember the DOS command-line interface.  I need something much more
ergonomic.



Thanks for all of your priceless knowledge.  I feel like we are a little
nerd family.
