Solar Generators For Home, Cabins & Outdoors
Solar Generators For Home, Cabins & OutdoorsIf you need a solar generator backup system for your home or remote cabin then you've come to the right place. Solar Generators really come in handy during blackouts resulting from hurricanes, earthquakes and other natural disasters. With other generators such as gas generators, you need to go to the gas station to refill the unit (you and hundreds of others.. can you imagine the long lines). Gas generators are also noisy and smelly and gas is far from free in fact it's very expensive these days. With Solar Power Generators you get clean, quiet and reliable power and the best part is that the power is free when using the solar panels! Now more than ever is the time to get a Backup Solar Generator Solution for your home. [Read Our Solar Generator Buying Guide]

Solar Generator Buying Guide:Before buying a solar generator for your home or a solar generator for off grid use there are some considerations to make before making a purchase. As with most solar systems, ranging from very small device chargers to larger solar powered generators for refrigerators, an inventory of what you need to run and for how long you would need to run them is required. From a frugal persons point of view, not only does this ensure a system capable of meeting your power needs it also ensures you do not overspend on a solar generator that produces power that exceeds your power needs.
As we have done throughout the site on other buying guides, here is a quick formula for calculating your power needs based on which appliances you want to power with your solar generator. I recommend you make a list of each one of the items you want to power along with how many hours they will be in use daily. The next step is to add the power consumption of each in watts or amps to your list.
Your list should look something like this:
1. Refrigerator: Continuous use 24 hours a day, Power consumption: *100 watts (*average continuous duty, energy star rated)
2. Lighting: 4 hours a day, Power consumption: *15 watts x 5 = 75 watts (*LED or CFL energy saving lighting)
Now you can simply add up your total power needs so you can shop for a solar generator that is suitable for your specific power needs.
Total power needs:
2400 watts (Refrigerator at 100 watts x 24 hours a day)
300 watts (Lighting at 75 watts x 4 hours a day)
Total: 2700 watts needed from your solar generator.
Now we can begin to shop for a solar generator that can power 2700 watts a day. Please note 2700 watts also translates into 225 amp hours, this is calculated by dividing 2700 by 12. For more assistance on converting amps to watts please visit Google and search for a watt, volts, amps conversion calculator. You will find this useful while shopping and researching solar generators.
The next step is to understand how a solar generator works so you can actually match your appliance specs and power needs with an available solar generator online. This is important because just about all solar generators are comprised of three components: a battery or bank of multiple batteries, solar panel(s), and an inverter. Below I will briefly discuss each of these components and describe how they relate to sizing your solar generator based on your power needs that we gathered before.
The Solar Panels with your Solar Generator
Many of our solar generators come with multiple solar panels for maximum power back into the battery bank that will be running your devices. You will want to consider how long it will take to replace the daily power you will be using so you can start fresh with charged batteries every 24 hours. You should also figure for solar power generation to occur during day light hours only. I usually use 10 hours a day as a conservative rule of thumb. Using our 1800 Watt Solar Generator as an example you will see it comes with 1) 140 watt solar panel. So letís simply compare the total power generation you should expect daily: 140 watts x 10 hours a day = 1400 watts, with your power needs which are 2700 watts. As you can see there is a short fall of 1400 watts daily. For purposes of this solar generator buying guide, you would simply need another 140 watt solar panel. You can easily add more solar panels to most of our solar generators online. To summarize, by making the basic calculations above you can assure you pick a solar generator that will provide enough solar panel power back into the battery bank to keep up with your power needs on a daily basis.
The Batteries or Bank of Batteries with your Solar Generator
All Off Grid Solar Generators come with a battery source for storing power inside your generator system. You can look at your battery as being the gas tank inside of a gas generator or even a gas tank in your car before you go on a road trip. The basic concept is that you will need to have enough gas in your tank in order to get to where you want to go and a large enough gas tank. The same thinking applies with your batteries with your solar generator. Using our example above you need to store 2700 watts of power daily to run your appliances therefore you will need a solar generator that can hold 2700 watts in itís battery bank. Battery capacity is normally specified in Amps. A simple way to convert Watts to Amps is to divide total wattage by 12 (12 represents 12 volts which is the main source of power from your 12 volt solar panel) so in this case you will need battery capacity of 225 amps to meet your daily power requirements. So back to our gas tank analogy, when shopping for a solar generator you must make sure that it comes with a battery bank (gas tank) that is large enough to store the power (gas) you will need to run your appliances.
The 110V AC Power Inverter with your Solar Generator
Selecting a solar generator with a large enough inverter is also equally important as analyzing your solar panel, and battery bank needs. Your 110V AC Power Inverter that comes with your solar generator basically converts the 12 Volt power produced by your 12 volt solar panel(s) and 12 volt power stored in your batteries to 110V household power for running appliances like refrigerators. The first specification you need to look at is the maximum output power of the inverter. The output power of the inverter represents the amount of power the inverter can supply to your appliances at any given time. For example, an 1800 watt inverter can process 1800 watts of 110V AC power at any given time so you must be sure to select a solar generator with an inverter capacity equal to the maximum amount of power you will be processing at any moment. As a general rule of thumb, you should take your largest power drawing appliance or group of appliances that will be running at the same time and add up the power usage. Once you have added this up you can simply choose a solar generator that has an inverter that is capable of processing the power you need. If you wish to run a 1500 watt air conditioner you will at least need a 1500 Watt inverter. Please note in our example above we needed 2700 watts of total power over a 24 hour period of time. However, for purposes of selecting an inverter you will need to ascertain what the maximum surge and or start up wattages are for your appliances so you can select an inverter that matches that power demand.
Now that you have a basic understanding of how solar generators work and the basic components with each solar generator kit you can begin to take an inventory of what appliances you would want to run and start sizing a solar generator at Earthtech Products.
