Just a quick demonstration of my off grid solar powered garage door opener. I put in this Sears Diehard garage door opener with battery backup six months ago. The motor within the opener is a 12VDC device and was designed to be powered by a smaller 4.5AH 12V DC sealed direct acid battery in situation grid electricity was lost throughout a brownout or blackout. I included a different 8Ah battery wired in parallel to the inventory 4.5Ah battery to give it far more reserve if we experienced several times of very cloudy climate. My solar panel is a 20 watt ebay Chinese device that I acquired for around $sixty.00. I experienced a Morningstar Sunkeeper solar charger sitting around so which is what I utilized. If I experienced to obtain a new one I might obtain Genasun GV-4 4amp MPPT solar charger as an alternative due to the fact it would harvest way far more power than the PWM controller for each a provided total of sunshine. Oh yeah, the cable from the solar panel to the cost controller was produced from a 12 gauge extension wire which is climate evidence, far more or a lot less.
I put in the technique about six months ago and have not experienced to plug it into the wall the moment while that could be effortlessly accomplished in situation there had been as well quite a few cloudy times in a row. I did not modify the garage door opener in any way. The point of this set up was to see if it could be accomplished and I can say sure, it can be accomplished for about $150 in addition to the garage door opener. Probably another person who watches this video clip might genuinely require to have a solar powered garage door opener. Now I won’t pay back just about anything to open this garage door at any time all over again!
Think it or, not most garage door openers draw 4 watts consistently if they are plugged into the wall which equals 35 kWh for each yr! I figure I conserve about 50kWh for each yr or about $five.00 so my payback is *only* thirty many years. On the as well as aspect, I imagine I have a significant plenty of solar panel to electricity all a few garage door openers which would bring the payback down to 10 many years. We’ll see.
If you watched the video clip, the garage door moved a lot less than beautifully smooth with a whole lot of sound. I located out not long ago that I experienced to terrible, seized up rollers for the safety cable technique and the door moves silently and efficiently soon after replacing these two rollers. I am nevertheless utilizing my original batteries.
