Why do you need Golf Cart Batteries to use Solar Panels with a Grid Tie Inverter?
I'll check with him and find out what the AH are for sure. I believe they are 6V/210AH.
It may not be worth it as an attempt to "sell back" wattage to the utility, but it may be worth it to know that he would have emergency backup power available if he needed it, simply by having the system preinstalled and working. We have a tremendous amount of solar available to us here in AZ! But you do bring up a good point about the costs-vs-the costs on the photovoltaic system.
I guess the main thing I should do is design a Solor hot-water system, and start with cutting the hot-water expense out of the loop.
Current electric bill average = $300/mo, so anything that is one step closer to getting off the grid is a good planning/learning exercise if nothing else. HUGE air conditioning costs in the Summer monthes.
So, he (in fact we all) needs to figure out lifestyle changes to change expenses, and converting to an electric vehicle as much as possible has been one step. (using the golf cart for short trips, getting off of dependance on $2.50/gal+ gasoline, etc). And it bugs him that his battery-bank just sit's there idle the rest of the time, when it at least could be used as "backup household power" in an emergency, if not actually tied into the grid.
He would of course like to get completely OFF the GRID if possible.
And I know that a good inverter is one of the major expenses in this type of system, so being able to build it myself would not only cut costs, but be a great learning exercise as well.
Well, you've got to clearly state your criteria. Do you hope to somehow save money doing this?So, does anyone have an advice on the best OEM inverter/GTI that would handle the type of load that an AirConditioner would require.
That's an ammonia-hydrogen Servel Cycle refrigerator, a type of Adsorption cooling. IIRC the thermal efficiency is poor, and the amount of equipment needed to cool a house and the volume of chemicals would be quite high. There are other types of adsorption which are more promising than the Servel cycle for cooling a building. A particularly difficult factor however is the range of ambient temperatures at which heat must be rejected. A traditional HCFC compressor system loses efficiency when pumping heat out of a 70F inside to a 110F outside- BUT it can do it. Some technologies like water evaporation have a fixed temp differential they can generate, and past that it just can't pump any colder regardless of how big the system is.Couldn't you setup solar cooling the same way they make Propane refrigerators?
