Trying to figure the ele. needed to run my hot water boiler .I started to figure it out and here is what i got.
OIL.Fired hot water boiler., useing one zone.
-
300 gal OIL for 3 months in the winter.from dec or 12th mo. to Mar or 03 mo.
3x30=90 days
nozzel Burns 1 gallon per hour.
90x24= 2160 hours
2160 /300 = 7.2 hour per day.
.
Oil Burner 1.7amps
circulator .8 amps
total 2.5amps per hour
.
7.2 x 2.5 = 18 amps per day.(24hr)

;
2 Deep Cycle batteries each 115 AH.= 230AH
.
solar panels are putting out about 8amp for about 4 hours
8 x 4 = 32 amp hr.
.
Would a 700 watt pure s. work. Im basing it on 1.5 amp = 100 watt. then plus start up
I know their is loss for the inverter and you only can drain down the batteries so far.
So that should run that fine. [ right ]

No, no, no. Amp Hours means nothing without specifying a voltage. 2.5 amps hours @ 12 volts = 30 watt hours. 2.5 amp hous x 120 volts = 300 watt hours. I seriously doubt your oil burner and and circulator use 12 volt DC. Most likely they use 120 volts AC or possibly even 240 Vac. You have not accounted for conversion and charging losses of of a battery system of about 50% which now brings you up to 600 watt hours per day. It would be foolish to to take any of that off grid and replace with battery. Geez a $400 battery every couple of years to replace $20 of electricity is not a smart investment, especially for someone who claims to be an accountant. Well unless you are a government accountant.

I just found this chart http://www.ktbattery.com/myapp/solar-tool.html and it came up with about 300 something watts, or about 28 amp hr. for the 7 hours a day. So with 230 ah ,I should run that with no proublem. [I think]
I'm just Asking a question so please dont get soooooo hot about it.[man] and I'm not spending 400 on a battery.

John - Don't take offense. Sunking is very direct and most often is "spot on". He is simply trying to make you aware of the truth involved with voltaic solar power "solutions".

Your 300 watts sounds about right if you are only running those two pumps you describe on 120v. 7 hours a day gives you a bit over 2 kwh per day at 100% efficiency. 2 kwh here only costs about $0.25 - that's but $90 a year. You'll easily spend 10x that much for a dependable 2 kwh per day solar system and have maintanence costs of top of that too.

Not even close. Based on 120 volts AC daily watt hours = 120 volts x 2.5 amps x 7 hours = 2100 watt hours. That means you need a 10 Kwh battery and at 12 volts is a 833 AH (10,000 wh / 12 volts) or 600 pound battery (60-lbs/Kwh). So you are right you will not be spending $400 on a battery to run it, more like $2000 ($200/Kwh).

hot about it?? I was thinking Sunking was pretty cool (and low on cost) about your initial post.
Your numbers don't make sense. You start off by averaging daily burner time when in reality some days are colder than others and burn time is more, more watts used that day. You then give (the average) amps at 120v and try to wring them out of a 12v battery? ...and want to do it all on 400watts (32Ah x 12v) a day from your panels????
nuts

sunk, I hate to blow your foolish mind but read this review from some on . oh he only has 2 batteries.

This is a great backup inverter. Have a wood boiler and when power goes out it will over heat faster then when I can get the generator runing. I have tested this inverter and timed it to 60 hours on 2 12v 105 A/H battery's. It will not have to run anywhere near that amout without a charge from my generator or wind or solar system. Now I even have lights in my generator room to get it started and hooked up. Love it for being quiet and it allow me to turn generator off at night so i do not have to here it and worry about running out of gas. I have also tested it with the same set up running 3 lights a refigerator and the furnace and will last for 2 days

I try to help out people NOT PUT PEOPLE DOWN. big difference

John

Sunking was trying to help you out. His way may be very blunt but it is to make sure you don't go spending a lot of money for a solar power system that will be very expensive and under powered.

Even if you live way "off the grid" running equipment on a generator will be much cheaper than solar. What you would save by not buying batteries you could easily spend on installing a large propane or diesel tank for the generator and still be ahead of the game.

You are not stupid. You are just misinformed as well as not really understanding how much power you need to run your boiler. Going with too small of a battery or pv panel system will cause you more problems and cost more than you should spend. Let us help you find a good solution for your needs.

Those two 105 AH batteries may work great in the short term but probably will not last a year let alone 5 years. To protect your batteries your inverter size in watts should equal you battery size in AH. So at 210 AH you inverter should be around 200 to 250 watts in size. If your inverter is bigger you have the potential of draining you batteries too quickly and shortening their lifespan.

SUNEAGLE. As you say "let us help" would be nice for OTHERS on here ,seeing were they try not to put a person DOWN.

John I am a licensed Professional Engineer of 30+ years. It takes a minimum of of a 4 year engineering degree with a minimum Bachelor Degree in Engineering . I have 6 years and a Master Degree. It also requires 5 years of documented professional design experience, and two grueling 8 hours written test test five with 5 years apart test to obtain a PE license. Basically what a Medical Doctor has to go through. In my 30 plus years is power generation which includes working with all the major battery manufactures engineers and Phd R&D guru's. I also set on IEEE 450 and 455 committee who write the standards for batteries.

So you can believe anything you want from the Web. I do not care what you think. I am not going to sell you one darn thing or make one single penny from you. I don;t care if you waste your money, that is your own dang problem. Wise up or get lost and bankrupt. Just like a Doctor I do not care one way or the other, as I cannot afford too as it would cloud my professional judgement. It is your problem, not mine. All I am telling just like a Doctor would loose weight, quit smoking,, eat right. or you will die sooner rather than later.

FWIW my wife is a MD, and she will charge you for professional advice. Mine on here is FREE.

You do not need solar to do what you want. Just a decent battery charger and properly sized battery. Want to go a week without power?. Add a small generator to charge up the batteries in a few hours with $2 of fuel. Quit wasting your money and our time.

[conntaxman]

I forgot to say, their is also about 4 hr's of sun a day. and the panels were putting out say 8 amps.So now you only have about 3 hours to supply ele.
