Power Inverter

This power inverter circuit will provide a very stable “Square Wave” Output Voltage. Frequency of operation is determined by a pot and is normally set to 60 Hz. Various “off the shelf” transformers can be used. Or Custom wind your own for best results.

An inverter is an electrical device that converts direct current (DC) to alternating current (AC); the converted AC can be at any required voltage and frequency with the use of appropriate transformers, switching, and control circuits.

Additional MosFets can be paralleled for higher power. It is recommended to Have a “Fuse” in the Power Line and to always have a “Load connected”, while power is being applied. The Fuse should be rated at 32 volts and should be aproximately 10 Amps per 100 watts of output. The Power leads must be heavy enough wire to handle this High Current Draw! appropriate Heat Sinks Should be used on the RFP50N06 Fets. These Fets are rated at 50 Amps and 60 Volts. Other types of Mosfets can be substituted if you wish.

There ARE Limitations! I have had numerous requests for an Inverter for 1000 watts and Even MORE. Sorry I Don’t feel this is Practical. At 1000 Watts and operating from a 12 Volt Source, the Input Current will be close to 100 AMPS. That would Require a HUGH Size of a Primary Wire.

Stand Alone solar panel inverters function to change direct current (DC) from a battery to Alternating Current (AC). Stand alone inverters, which range from around 100 watts to as much as 8000 watts, are used to power a vast variety of personal or small business projects. Lower watt stand-alone inverters are often used to power laptop computers, whereas high-watt stand-alone inverters could be used to help power an entire household. In order to calculate what class of inverter you need for use with your solar panel, you will first have to determine the maximum sum of all of the Alternating Current loads in your project (or home).

This is the wattage you need from your stand alone solar panel inverter.

You can usually find the wattage rating on your home appliances by checking the power cable. The sum of these wattage ratings is what you need to determine the wattage you need from your solar panel stand-alone inverter.
