Looking to upgrade my generator. Currently have a couple of portables to keep freezers and well pump running in case of emergency. Thinking about getting a bigger diesel whole home generator. But whatever I get, I want to have an abundant fuel supply. How well does diesel store in large quantities. I know with gas you can put in an additive (Stabile sp?) can you do that with diesel? Propane will last but burn rate is high and resupply might be difficult. Thoughts? Advice?
Diesel will store for quite a long time if you learn how to properly treat it and rotate some out of the tank every once in a while. Stabil makes diesel additive. You can find it on Ebay. I store about 900 to 1000 gallons on my place. Much less dangerous than storing gasoline. Besides, gas just doesn't last long. It also typically has Ethanol in it which eats up carburetors, etc. I have a diesel powered truck with a 90 gal transfer tank & 12 volt pump in the bed that I use to fill my storage tank. Once my 1000 gal storage tank is about full, I will dump a gallon of Stabil in the tank and then take the fill pump and circulate it back into the tank via the fill spout. Over time I will pump back out about 200 gallons or so into my tractors and truck. Once I bleed that off, I fill up the 90 gal transfer tank a couple of times and replace what I used up. That lets me keep a minimum of 750 to 850 gallons on hand at all times. I have been doing it for over 10 years+ now. Works great. I still have some Trump era $1.65 a gal diesel in there. In a small shed next to that storage tank I have a 20KW diesel generator out of a old GTE telephone switching station. I can use that to power up everything but would prefer not to do unless absolutely necessary. 1.6 liters per minute on 50% load and noisy. Noise attracts attention. Especially when everyone else is without power.
All of that said, I would highly recommend looking into some solar powered fridges and freezers. I have both a Sundanzer chest type freezer and fridge (24v). They are very power efficient. I power them 24 x 7 with four 12 volt, 200ah Lifepo4 batteries. These are kept charged by one 310 watt Canadian solar panel with the option to connect to a 2nd if need be. So far they are working perfectly for well over a year.
So far as a water well goes, my next project is to power up a Grundfos well pump that I already have in place with four BP 175 watt solar panels that pump onto a 1500 gal tank up the hill from my cabin and garden. Hopefully gravity will do most of the work for me. If not, I will come up with a pressure pump.
