The home solar power generation system provides a simple, cost-effective way for ordinary homeowners to generate electricity through simple sunlight.These systems have been continuously improved over the years and new innovative features have been added to the design.One component of the great changes that have taken place in recent years is the solar inverter.The solar inverter is part of any solar system that is responsible for converting DC power generated by solar panels into AC power that can be used by the home.In the simplest form, they only accept this DC power supply directly from the panel and connect to your home wiring panel to allow you to use the free AC power they convert.Although this seems to be a trivial feature, these solar inverters still require fairly complex circuits to ensure that the AC power supplies they produce meet the common standards of 60Hz and 120 VAC required by most homes.Over the years, these simple solar inverters have taken on additional features, and in addition to the conversion task, it can be found today that they perform several key functions.Most modern inverters are smarter than older models and are actually located between the utility power supply provided locally to the home and the solar system itself.They power homes like a traffic police officer, and when solar power is available, they intelligently switch between solar power and utility power when the solar system is dormant at night.These modern solar inverters are able to sense when the solar system will start, ensuring a reliable power supply for the home at all times.Many modern solar systems are actually designed to provide more power during the day than the home.These modern solar inverters are complex enough to deliver excess power back to local utilities, creating credit for families.So homeowners can use these points to help offset the cost of electricity they need to buy back from utilities at night.Because the solar inverter is connected to both the home and the local utilities, it can guarantee that the home will use free solar energy as much as possible, and the excess power will not be wasted.Another responsibility many of these solar inverters undertake is to charge any battery connected to the solar system.Some homeowners will install a set of batteries at home that will be charged during the day with the excess power generated by their system, they can then be used later in the evening to reduce the power they need to buy from a local utility.If a local power company is out of power due to a storm, these batteries can also be used to power the home.Most modern solar inverters can handle the charging of these batteries and then convert the power they store to home use when needed.One recent innovation in these solar inverters is the way they are installed.The old system will usually have a large solar inverter that can convert all the power provided by the solar panel.This requires a long line from the panel on the home roof to the solar inverter, which is usually located on the ground near the electrical panel.The challenge of this design is that there is a loss of power due to these long lines, which may reduce the efficiency of the system.The new system is installing a small set of micro-inverters that are actually located in the solar panel itself.By converting the DC power supply to AC power on the solar panel, you can eliminate most of the losses suffered by the old system.
