How to setup a proper solar power system
How to setup a proper solar power system.
DC to AC Power Inverters have become more and more useful over the past few years. With the increased efficiency of solar panels many people are looking towards that option to reduce utility cost and also leave less of an environmental foot print. The use of a power inverter within a solar system is essential. First let me explain all the tools required to properly use solar energy to power your home electrical devices. Of course you will require your solar panels, these panels are available in a large verity of wattages. You will want to calculate the load you are looking to run within your system and the solar exposure available in your area before selecting your panels. Once your solar panels have been installed you will then need to connect your panels to a solar charge controller. The solar charge controller will take the inputted solar energy and convert it into a specific voltage charge that can then be used to charge your stored power or battery bank. Now that you have properly pulled the solar power into a battery source you are ready to use that stored energy to power your daily devices. But as you will see a 12 volt or 24 volt battery will not include a standard plug input. That is why you will need to connect a DC to AC power inverter to your battery bank. DC or direct current to AC or alternating current inverters are the perfect tool to use in any solar system. When selecting the proper inverter you will need to make sure you calculate the full desired AC load you need to operate. You can find that information either in AMPS or in Watts, the information will be displayed on each specific device. DC to AC Power Inverters are available in a large array of sizes for 400 watts to 6000 watts. A four hundred watt units is ideal for charging small electronics such as laptops and cell phones. Six thousand watt unit can handle up to 50 amps of continuous power which can be used to run a full size standard household worth or electronics. Now that we have briefly gone over all the different components of your solar power system we can now explain the different types and proper installations, I will also post several images diagramming the system.
If you are using a solar system as a home backup then you will be able to find panels from anywhere between 15 watts to 500 watts. Before purchasing your panels you will want to calculate the amount or solar exposure in your geographic area and also the size of your battery bank. Because each area is different you will want to contact a solar panel installer in your area. If you need solar panels your an industrial site then the same research will be required and several panels will need to be wired in series.
Regardless if you are using one solar panel or several you will need to wire the primary panel in a solar charge controller. A solar charge controller is a device that allows you to transform raw solar power into a desired voltage output. Most solar systems will use a 12 volt or 24 volt battery bank to store the reserved energy. These batteries will list their capacity in amp/hrs the higher the amp/hrs the higher the reserve power bank. Due to varying solar exposure from day to day in every area you will want to make sure to have enough batteries. Because we can never predict amount of sunlight or cloudy time you always have extra power so you are not stuck in dark.
Now that your battery bank is loaded with reserve power you will need a device to use that power stored power. A dc to ac power inverter is the ideal device to invert your direct current stored in your batteries and output the power into alternating current. Alternating current is the type of current required to power standard household electronics. The required power inverter for your setup will be determined by what type of device you are looking to run. The power requirement for each device will be easily listed on the power rating label. If you have a specific application you are looking to run then you can easily find an inverter that matches your requirements. If you are looking to power a full grid dc to ac power are available up to 6000 watts of power. Most inverters will include direct outlets, other allow you to wire directly into your electrical grid. So if you are using the system of grid at a work site or in your home and want to use your already wired home outlets then both options are possible.
Please see the images posted below clearly diagramming the each part of the system, as you will see once you understand the parts of the system it is very easy to understand what is required and how to properly choose the direct elements. Now that you know all the components required in proper solar power system your are ready to start researching your own system. Make sure you consult a professional when selecting your panels, solar charge controller, batteries and DC to AC power inverter.
