If there is an AC source, either grid on AC input 1 or generator on AC input 2 then there is a possibility of sharing the load between the 2 sources.
I think you understand, but I'd like to point out for others, the XW will only qualify and connect to a single AC input at a time. It never will connect to both inputs at the same time.
The weatherhead is on an out building (200a with well pumps) and the best roof for solar panels. Sub panel with AC in the main house. 100a
Seems like it would be a good install, if your house would be fine on the 60 amp pass through.
Just replace the 100 amp breaker at the weather head for a 60
Pull that input wiring from the 100 amp panel and install on AC input 1 on the XW.
Install new wire from XW output to sub panel.
Also need to calculate if a 3 kw battery will run the house after I shut off the generator until the next AM. Two fridges & 1 freezer, minimal lights & possible the heater kicking on a few times, if the outage starts after I go to sleep & haven't started a fire.
Doesn't sound like enough battery. I'd recommend an energy audit or monitoring your overnight use. That could be as simple as checking the meter at sunset and sunrise.
Is this asking too much from the XW inverter?
Thanks
My house is 1400 SQ ft, no well pump, single fridge. We run the central AC off the XW. You should be fine, but your actual numbers will be the deciding factor.
The XW can do 6800 watts continuous. 12,000 watts max, the overloaded curve is very generous. 8,500 watts for something like 30 minutes.
My base load overnight is 300-500 watts. It's an easy life for the XW.
I'm using the older model XW+ but I believe this is applicable to the Pro as well. The Peak Load Shave Timers are based on 2 x 24hr clocks. One for start time and one for stop time. So other than having an automatic Daylight Savings time adjustment, it does not have the capability to self adjust based on Sunrise and Sunset like for example a home automation system. Likewise it does not differentiate between weekends, off peak, and weekdays, on peak times.
Same on the XW pro.
But, peak load shave is likely to be a 24/7 concern or based on utility peak rates. So, I'm not sure sunrise actually effects the need.
There is also another problem with regard to Peak Load Shave and automatic recharging. There is a hard coded firmware feature that forces the Schneider to exit Peak Load Shave mode at +0.5V above the recharge voltage setting. This means that an automatic recharge cycle is not triggered so you would have to initiate it manually everyday or set up a PLC on the RS485 comm port. GXMnow and 400bird have posted info on this subject.
This recharge issue, load shave, PLC, etc is only a concern if your solar is AC coupled or you want to charge from the grid.
With DC coupled PV, everything should work normally.
I'd like to set up self-consumption in the evening (with a reserve SoC), and then to recharge from the generator input during daylight hours (the generator input would actually be Sunny Islands with AC-coupled solar). But this would be a pain to keep up with as the seasons change...
AC coupling on the XW leaves lots to be desired if you are on grid. Off grid, it will charge normally and frequency shift to control the PV inverter.
Also, on the XW you don't connect PV to an AC input.
And why are you connecting a battery inverter (Sunny Island) to a different brand battery inverter through the AC? There's a lot of wasted efficiency there. Plus you could just run your loads right from the Sunny Island.
BentleyJ, I quoted you about 1000 times here, mostly to agree or add to what you said. I couldn't figure out how to quote you but address the OP or others. You know this equipment!
