That is going to be one whopping battery bank when you are finished. Are you going so high with your watts so that it can handle a whole house startup surge? It seems like 10,000 watts is all that is really necessary if you discount the initial startup of refrigerator compressors etc.

I found a 67 watt, 12.6cu foot, 24 volt, refrigerator freezer. The power is for 2 one ton, mini split systems that draw 900 watts each. For a combined 1800 watts, I can heat and cool the whole house.
My wife has MS, and is not able to take the temperature changes. So I am removing that problem. But that is why the overkill on the battery system. I have also located a wind generator (1700 watts) that should give me about 450 watts at our average wind velocity here.
All of those devices sound rather efficient. Yeah wind or hydro is a great secondary system for those overcast days. I guess you already know about the dump load factor when it comes to wind turbines.
I plan on efficiency, and it has taken a while to find the right ones, but I am happy with what I have found thus far!
With the added insulation, and the new windows, I will be well able to power the entire system, and generate a surplus. I will also be running my water well from this system too.
Already have the dunp resistors here for the full output if I need it. But the Property is currently on the grid, so if I get enough extra power, I have a synchronous Inverter that will allow me to sell it back t the power company. The dump load is in case the SHTF, and there is no where to sell the extra.
If not, I can use it to piggy back another inverter, if I find one close to overload. I may pick up several more, they are so useful.
I plan on building and adding, a vertical axis machine of my own design; when I get the chance.
:)Nice! Sounds like you have a pretty well thought out system there. I like the vertical axis turbines much more than the traditional ones.
I am curious what type of inverters that you are going with. I have been looking at various ones for when I upgrade my current system. I have been leaning heavily towards the ones made by Outback Power but am always curious what other folks use.
Going 24 volt, I have a mixed bag. I have been buying them as I find them for a number of years. I even ended up with a couple of 50 Hz units, that I will look at and convert to 60 Hz here.
I decided to go with multiple smaller inverters, because if I loose a unit, I will still have power available. I will also store a half dozen 1500 watt units for spares. I will also store some of the synchronous 1000 watt units in case I need to parallel them with a 1500 watt unit, for a specific use.
I will be adding relays into my AC power panel that will allow me to drop back to line power (Or generator) if my batteries get too low. Those same relays will allow me to put an inverter onto several legs on the panel, so I will not need 20 + inverters.
:)Excellent!
I plan on running my lights, refrigerator, and fans (house and heat exchangers) directly off of the 24 volt battery buss. No inverter conversion losses that way.
I will run the 24 volt buss in the abandoned central HVAC duct. The 24 volt buss wiring will be within the 2 inch added inside insulated wall. Since it is 24 volts, it is intrinsically safe, and does not need to be in conduit.
