The Purpose of DC to AC Power Inverters
Before choosing to install a solar energy system you need to know the different components of the system. Most solar panel systems consist of the solar panels themselves, connection wiring, possibly a bank of batteries and a dc to ac power inverter. All of the components need to be specifically sized to your home s power needs and be functioning properly to provide the proper amount of energy.
The solar panels provide a standard amount of direct current (DC) when exposed to the sun. The size and number of these solar panels is matched to the electrical requirements for your home. You need to make sure you have enough of them to generate the correct level of electricity to allow you to eliminate your need to buy power from the local utility.
This DC current needs to be regulated and ultimately converted to AC current so that it can be used in your home. This is what the inverter does, and choosing the right one can take some consideration.
The DC to AC power inverter is one of the most critical components in your solar panel system. Its main function is to convert the DC current from the panels to AC current that the house can use.If you decide to install a bank of batteries as part of your solar power system, the DC to AC power inverter may be responsible for controlling the charging of these batteries and disconnecting them from the system when they are fully charged.
In addition to interfacing with the batteries, the DC to AC power inverter is also in control of the switching between the solar supplied power and the local utility supplied power. During the evening when the sun is down, the DC to AC power inverter switches back to the local power utility for the power your home needs. You will have to purchase back some of the extra electricity you produced while the sun was shining.
If the solar panel system was sized correctly, this back and forth should cancel each other out and you should not have any electrical cost to run your home, and the inverter is responsible for handling the switching.
If you are using a battery bank, the inverter will switch over to that as a source in the evening or during a power outage before connecting to the local power utility. This will allow you to use the energy that was stored while the sun was shining to power your home and save you even more http://www.carspa.cn/
