I'm looking a battery for use near solar power and it has the following specs.
Volts 12
Capacity (a) 20-hr rate 120
Capacity (a) 100-hr rate 145
How does this translate into running a 1000 watt appliance and how long you can run it beside this battery.
Answers: Watts = Volts * Amps.
So a 12 volt battery-operated supplying 10 Amps is producing 120 Watts of power.
Batteries are rated contained by Amp-Hours. For example one battery might be rate at 100 Amp-Hours. That would mean it could supply 1 Amp for 100 hours or 2 Amps for 50 hours. But it could probably not supply 100 Amps for 1 hour. Batteries work better at low rates of use. Your examples are 20 hour rate give 120 Amp-Hours, meaning it can supply 6 Amps for 20 hours (6 Amps times 20 hours = 120 Amp-Hours), but if you drain it more slowly, taking 100 hours instead of 20, it will impart you 145 Amp-Hours, which would be 1.45 Amps for 100 hours.
To get Watt-Hours, multiply by the number of volts. Most such battery are 12 volt (but not all are so check). So a 12 volt battery-operated that has a 120 Amp Hour size has a 12 * 120 = 1,440 Watt-Hour size. Since one kilowatt (kW) is 1,000 Watts, that would be a 1.44 kilowatt-Hour (kWh) battery. You electric bill is usually contained by units of kWh. Check your electric bill to see how copious kWh a month you use, then divide by 30 to obtain the number per day. That will pass you an idea of how oodles batteries you stipulation to store enough dynamism to make it through the dark if you are off grid and relying on solar panel for all your power. I suspect you will be shocked at the number of battery needed.
First of all near solar power one doesn't have anything that uses 1Kw of electricity. Most Renewable Energy homes use 200 Kw a month. The number of solar panel alone would be $50 - 75K alone, add another $25k for battery, for your 1Kw appliance. One has to know that for every $1 of vitality you don't use, you save $5 to produce that power.
Depends on where on earth your living.
