So what I did for now DC 120-volt open-circuit 104 vote under low at 8.2 for amps and here’s the Missouri wind and solar DC thermostat it’s going to heat it up a little bit to temperatures the 104 degree shot off one but I don’t think it’s going to shut off its keep on Arkin so here we go so you can hear its arguing and see the blue bark in there but it’s not shutting off just unable to shut off so you can see the eight amps is still going there’s still connection it’s trying to shut off what it is not possible [Applause] we’re at and 31 [Music] one hundred sixty three hundred sixty three degree that it got up to and it’s still not able to shut off and I think it fuse the plate together so now it’s not even trying to shut off anymore and it’s super hot so it’s not working not at 120 volt DC and I can’t afford a really expensive DC relay the good DC we lay are like $250 to $300 for a good high voltage DC relay so basically right now.
I just left I took the thermostat out and just run it directly to the elements so really simple solo directly to element let it heats up the how does a tankless water heater work for my experience on a good day perfectly sunny day my system will do my panels will output about five kilowatts on a good day and five kilowatts will heat the 40 gallons of water from 65 degree to 120 degree max and so far my water has been getting around on a good day getting it around 115 120 I know that there’s no way to prevent there’s no way for the solar to shut off automatically now that’s not what I wanted it I wanted it to have a thermostat so where if the water get hot enough it will shut itself off but as of right now I haven’t figured out a solution how to do that yet but right now I’m just rely relying on this relief valve a safety valve that built into the tank if the tank get too hot or overpressure that’s going to relieve the pressure and then you know let some of the hot water out so as you can see right here they remember the reason.
Why I got this meter is that it it gives you the total wattage so right there eight thousand three hundred and thirty-one watts and has been running for three days and four hours basically what happened is I had this thing running for about two weeks now but the power went out the other day and this thing require a power supply and I had it plug into a wall adapter for the power supply so the the the basically when there’s no power no grid power the power meter turned off which is kind of stupid but that’s I haven’t figured a way how to go around that but this thing needs to be need to remain power the whole time otherwise when it loses power you won’t remember previous value so that’s going to reset itself so that’s what it did resets and it forgot everything so basically three days and it’s only doing eight kilowatt that’s because we’ve been having a whole week of two or three days of completely complete overcast so wasn’t much power coming in but today finally the Sun comes out and we got good power.
Today so 950 watts and it will stay at 950 watt starting about 11:00 a.m. until like 2 to 2 or 3 p.m. then it start you know slowing down and dying down again but that’s how much you get so 5 kilowatts a day heats the water pretty good enough for 2 to 3 people um and if it’s a cloudy day then the water doesn’t get hot enough on the top and that’s where the grits come in and give it another thousand watts and now heats the water up and keep it up but so far it’s working great so if you have any questions just leave me some comments and what I say this is the most efficient way to to and probably the most cost-effective to because the tank the tank cost me three hundred and twenty dollars the solar panels they 320 watts each and I bought four of them so that’s six hundred dollars so plus the tank plus the univac plus all of the water in you know I’m anywhere I think I was about eleven hundred dollars in it into the whole system including the tank but you can’t really factor in the tank because the tank you know it was needed to be replaced anyway.
So if you don’t factor in the tank the whole solar side of it only cost me about eight nine hundred dollars so that’s pretty good and I figure out probably going to get my my money back for the solar stuff probably in about a year to a year and a half and I’ll get my solar money back so hopefully everything can work out for the long run but I can’t really see why anything would stop working because it’s very simple solar panels going to your disconnects block go through the wire going into here another disconnects which go right into the tank nothing else nothing else can fail except the solar panels well maybe the the heating elements but you know that’s going to be a few years at least so any question just let me know thanks for watching you.
