Been following some fora about solar in different countries and am amazed how they are talking about 12v systems with dc-appliances.
Many times I've been reading "get out of "the 12v box"...??? On the other hand expert's advice is not to use batteries if there is grid available. Contradictio in terminis!
OK, I am one of those "suckers" who went offgrid in a big city and my energy use is now < 400Wh per 24 hours, cause I am using only low voltage DC appliances like a projector which I connect to a TV tuner and USB speaker total < 15w @ 5v.
* Projector 2A with only USB 5v input
* TV tuner 600mAh @ 5v
* Speakers 2-3w @ 5v
Not a TV-freak myself , this setup is acceptable for me although the quality of a 10w "chicom" projector with little lumens is "ofcourse" low.
Living in a tropical country with no aircon, but if needed 12v ceiling fan and other DC fans, acceptable low voltage DC lighting and for example also 8-15w 12v brushless pump and I'm lucky to be able to live with only (filtered) rain water. Cooking with gas.
Let me ask you experts a question:
If you want to use batteries concentrate your load as low as possible. This can be achieved if you ONLY have DC-powered loads. For those "suckers" who use DC-AC inverters with huge capacity batteries, better follow the advice of Sunking (see attached screenprint ) and use only grid with genset as backup otherwise your wallet will get more holes, right??
As far as I know there is for example no AC pump which draws +/- 15watts and can lift +/- 4m which I use 1-2 hours each day to fill my water tank. For the same result you perhaps can use few minutes AC jetpump instead but I use only 50Wp panel for my "chicom" brushless pump and no inverter. I also think there are not so many people that can watch TV using max 15w only.
If you want to discuss "standard of living and comfort" in combination with solar, you are wasting your time and mine. Just use the grid and no solar solar system (with batteties) at all.
For those who think I am one of those "green guys" , forget about green. My grass is greener than those "green dreaming suckers."
Just want to share my solar experience and thoughts as an amateur in the living off-the-grid world with solar.
