What is a split-phase solar inverter?

A split-phase solar inverter is a device that converts the DC power generated by solar panels into AC power and splits it into two lines to generate 120 volts and 240 volts for home use. It is mainly used by the United States of America in North America. Some other countries are 110 volts/220 volts, we take the US as an example here.

 

Why use a split-phase inverter?

(1) Compliance with the grid, the United States of North America uses a split-phase voltage of 120 volts/240 volts, the electricity generated by solar panels using split-phase inverters can be freely chosen whether to be integrated into the grid.

(2) High efficiency, split-phase inverters have higher efficiency than single-phase inverters in off-grid solar energy systems. For solar panels in areas with little or no electricity, the efficiency of power generation is of great importance, and split-phase solar inverters ensure the efficient conversion of DC to AC power.

(3) balanced distribution, compared with single-phase inverter split-phase inverter can be realized to a variety of different power distribution requirements, this can be distributed to the voltage is more convenient to use.

(4) Reduce losses, single-phase inverters can not provide high voltage current in the transportation process through the wire loss is relatively large, split-phase both to ensure that the transportation process of low loss also meets the demand for electricity.

(5) easy to install, split-phase inverters are easy to install and centralize electricity, making it easier to use solar renewable energy.

The working principle of split-phase solar inverter

Split-phase solar inverter will be converted to alternating current respectively to two power lines transportation, which there is a potential of zero neutral line both with its voltage difference of 120 volts, the difference between the two power lines and 240 volts.

Frequently asked questions about the use of split-phase solar inverters

(1) Can I connect more than one solar panel to increase the power generated?

Yes, split-phase solar inverters have the unique advantage of ordinary inverters, split-phase solar inverters can accommodate larger input power, he allows users to add additional solar panels according to the demand for electricity, while still enjoying high conversion efficiency.

(2) Will using a split-phase solar inverter damage my electrical appliances and what are the hazards?

Split-phase solar inverters produce 120V/240V compared to single-phase inverters to better adapt to the voltage of electrical appliances, and will not cause harm, if anything, the disadvantage of split-phase solar inverters is that they are more expensive than ordinary inverters, and are also more commonly used in solar energy systems.

(3) I want to integrate my solar system into the grid, can I do it with a split-phase solar inverter?

Split-phase solar inverters are inverters designed to fit into the grid of course you can realize the integration into the grid, which can reduce your home power consumption and save money.

(4) How can I use a split-phase solar inverter in my RV?

If you are considering using it in your RV, then you will definitely have a good experience. First of all, you can connect the inverter directly to your RV to charge your vehicle or use it for electrical appliances if you already have solar panels installed in your RV, and you don’t have to worry about the rainy weather, as the split-phase solar inverter ensures that the power is always converted at maximum efficiency.
