Understanding Watts, Amps & Amp Hours For Choosing The Right Solar Generator
How to determine which model and size solar generator is capable of powering your electrical devices:
This is most likely the first question that most people have who are shopping for a solar powered generator. And due to the cutting edge nature of this portable renewable energy technology, it is understandable that the average consumer may not have all the necessary information to make a well informed purchase. It's our job to provide the interested buyer with the more technical details that go into the decision making process everyone goes through when stepping up into the solar energy market and purchasing a solar generator. Below are the 3 most important sizing factors
3. Amp Hours
Watts are a unit of power that all of your electrical appliances are rated in and it is the total number of Watts that your electrical device consumes which determines what size solar generator (in Watts) that will be sufficient to power your loads. For example:
Let's take a 300 Watt mini refrigerator. To power this particular refrigerator you will need a solar generator with an inverter rated over 300 Watts. So when considering solar-powered generator kits on the Solaaron.Com website or elsewhere, you will notice that we offer The Outback-Mate500. At 500 Watts (1000 watts surge), this would be large enough to power the 300 Watt refrigerator in our example when considering our first of three factors, Watts.
Amp, short for ampere, simply put is a unit of electric current that measures electricity passing through a circuit. To determine which size and model Solaaron solar generator is right for you, simply determine the amp ratings on all appliances that you will need to run off of your solar generator. Next, determine which electric device draws the highest number of amps and that will be the number that you won't want to go over. For example in the simplest form:
If your TV is 2 amps, your radio is 1 amp and your refrigerator is 3 amps, then you will need a solar powered generator with a charge controller that is rated at 3 amps or more in order to handle your largest load which is the refrigerator in this example.
Amp Hour (Ah) is a unit of electric charge. In the case of a solar generator, it measures the state of charge of the battery inside your Solaaron solar unit. As you know, the included solar panel charges the deep cycle solar battery that is inside your Solaaron solar powered generator. This battery capacity is measured in Amp Hours (Ah) and is the “gas” in your generator, so to speak. Each of our units come with different size batteries ( i.e. 10Ah, 35 Ah, 55Ah, 125Ah etc..) and it is Amp Hours that you will consider when choosing your desired battery capacity. For example:
If you purchase a Solaaron Outback-Mate500 that contains a 35 Amp Hour battery and you want to figure out how for how long will it run your 3 amp refrigerator, you will simply divide the total amp hour capacity of 35 Ah by 3 amps. 35/3 =11 aprox. This means that your 3 amp refrigerator can run for roughly 11 hours on a fully charged 35 Amp Hour battery. And if you were to add a second 35 Ah battery on to this unit, you can roughly double this time to 22 hours.
Hopefully this 3 step explanation will serve to help clarify what are the most important technical factors that go into choosing a solar generator that is the right size for you. Remember: Watts, Amps and Amp Hours are these 3 factors. With this information, you should be able to make an educated purchase of the cleanest, most practical form of portable renewable energy; a solar powered generator.
