One of the key components of a home solar power system is the power inverter. The Photovoltaic (PV) cells on the roof will convert the sun energy into Direct Current (DC). The current will then be stored in deep cycle battery.
Since most of our home appliances use Alternate Current (AC), the power inverter will be used to convert the DC to AC.
So how do we choose the best power inverter for our residential solar power system?
If you need some really clean power similar to the type of power you will get from the grid, you will need an inverter which is capable of producing a sine wave with the same characteristics.
Why do you need an inverter which can create similar sine wave from the power grid?
The reason is because you’ll need clean power to effective operate the electrical appliances at home.
Let me explain.
The sine wave from the power grid has very low harmonic distortion. If you are using inductive load such as microwave oven or any devices that use a motor, good sine wave will let it running faster, quieter and cooler. It will also reduce audible and electrical noise on fans, florescent light, amplifier, TV etc.
An inverter capable of matching the sine wave from the grid will let your electrical devices run as if it is getting power from the grid.
The process of setting up the power inverter is actually quite easy. At one end of the device, you will see the terminal that will be connected to the batteries.
Most power inverter will generate heat when converting DC to AC. That’s why, most inverter comes with built in exhaust fans. Make sure there are no obstructions on the fan or it will affect heat dispersion.
On the other end of the inverter, usually there will be a 110 or 120 volt output. This is where you can connect a power outlet extension adapter where your electrical devices can be plugged in. You will also find the on and off switch on the side of the inverter and the grounding point.
Power Inverter For Solar System
It is capable of delivering 1000 watts of continuous power and up to 2000 watts peak power. The inverter will be sufficient to meet the demand of a medium size home.
