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.
:)Sounds great! I am curious why you say it is intrinsically safe because from my understanding (which I am always open to being wrong) any long runs of DC power is not all that safe.
All power is a risk, but anything below 29 volts is considered by regulation to be intrinsically safe (this is referring to flash over etc).
BUT, always use caution and fuse everything, it can still burn from current!
>:(Ah I see what you meant now. That is kind of funny that 29 volts is the number that is considered 'safe' I would have guessed it to be much lower than that. I learned something new there!
It is the government, so the actual number is 28, but the say below 29, because they think people are too stupid to know if 28 is okay, 12 is also fine.
AND WE PAY THESE PEOPLE! SMH!>:(LOLS! It is all in the wording!
