I sit here, 10:20 pm in Las Vegas. Having conducted a battery run time test on my brand new Victron Energy install of Dual Quattro 24/5000/120-2x100 120V, in Split Phase... they kicked out well above my low voltage threshold, and while I can get the inverter side running... I cannot get shore power to reconnect to charge the batteries, or power the coach.
It's now been over 6 hours. I resorted to reconnecting one of my Magnum 4000 Hybrid inverters to a 30amp shore cable just to try and charge the Tesla battery modules. Thankfully, it was only 94F ( 34.4 C ) today, and not last weekend when it was 108F / 42.2C.
Why... oh why... do my quattro's not reconnect shore power?
VE.bus monitor shows only green and normal readings, yet each timeout of the little blue bar, I hear multiple relay clicks, and again, nothing.
Actions I took to try and get shore power to reconnect:
- I originally had ESS assistant loaded, so I removed that from both quattro's
- I had UPS function turned on, so I turned that off and updated both quattro's
- I set the Grid code standard back to None from Other on both quattro's
- I tried changing the VE.bus config from 2 AC inputs, to 1 AC input ( I only use AC in-1 anyway )
- I tried changing the Leg2 from Floating with return, to just floating ( always set at 180 out of phase )
- I tried powering both units off via the mechanical switch for about 5 minutes
- I tried fully removing power from both units ( AC and DC ) for about 5 minutes
- I disconnected the quattro's output to the coach ( via the coach breaker )
- I tried so many times putting it from Off, to Charge Only.. to Off, to On, etc..
- Finally, I pulled out one of my two Magnum MSH-4024 inverters and powered it via a 30amp cord just to get the batteries charging again
Again, the Inverter will always invert ( as long as the battery voltage was high enough ).. but the shore power just will not stay connected.
So, my wife, dog, 3 cats and myself.. got to enjoy the heat of a Las Vegas afternoon, knowing shore power was just right there.. but wouldn't make it's way into the coach to run our Air Conditioners.
I'm super frustrated, wife acceptance factor of my new $7000+ Victron setup is at an understandable near 0, and I'm wondering what else I need to do to get these things working.
Note too that the quattro's are running the latest firmware ( 2748497 ). As I type this, the Tesla modules are now at 22.66 volts or roughly 55% charge, and still the Quattro's won't connect to shore power (it was suggested to me that the low battery voltage was to blame?)
I'm so very eager to hear any recommendations besides don't use Tesla modules. I know their voltage swing is atypical, but the Quattro's are supposed to run down to 19v, but clearly that did not happen here. And even so, why would they not permit shore power back into the system to recharge the batteries and/or supply the coach with power?
Please.. anyone.. help me get my coach powered back up.
Thanks,
