An inverter is a device that converts DC (direct current) in to AC (alternating current) which is widely used in homes and for commercial purposes. A solar inverter also works in a similar way only the source of the DC current is different in this case.
A solar inverter is a part of a solar energy setup that consists of photovoltaic solar panels, charge controller and batteries. The photovoltaic solar panel produces variable DC current and the solar inverter converts it into AC current.
Central inverter is the most common type of solar inverter used in homes. Although, a solar energy system requires an elaborate setup, it helps to save money in the long run because the energy used from the sun to produce electricity does not cost anything. In addition, solar energy system can be used to get electricity even in remote locations because it does not require connection to power or gas.
But, when it comes to choosing a solar inverter for your home, it is important to consider a few basic factors such as the type of inverter, its efficiency, its power rating, protection features of the inverter, etc.
How to Choose a Solar Inverter?
There are 3 main types of solar inverters depending on the output they produce.
- Sine Wave – This is what you receive from your local utility company or from a generator. The best thing about this type of inverter is that it is compatible with almost all appliances and equipments available in the market. Most appliances require sine wave to work to their fullest efficiency.
- Modified Sine Wave – This is almost like sine wave but it has a square pattern. It is compatible with almost all equipments, but the equipments will have low efficiency in case of modified cine wave and as a result they will use more power.
- Square Wave – This is the cheapest type of inverter available in the market but it is seldom used because it is not compatible with most appliances and equipments. It may however be used to run simple tools with universal motors.
Efficiency of an inverter is the ratio of output power to input power. The efficiency of a solar inverter depends on its load. It is never possible to achieve 100% efficiency because some of the power is lost due to heat generated.
An inverter must be able to meet two power requirements – peak power/surge power and typical power. Surge power is the maximum amount of power that an inverter can supply for a short period of time. This surge is required for staring up appliances with electric motors such as pumps and refrigerators. Typical power is the power that an inverter can supply on a steady rate. Typical power is much less than surge power. An inverter with power rating of 50 watts is good enough for home use.
4. Power Rating
Solar inverters come in different power ratings ranging from 50 watts to 50000 watts but a household seldom needs more than 11000 watts power. Almost all standard solar inverters come in 50 to 5000 watts range.
5. Internal Protection Features
It is best to choose a solar inverter that comes with good safety features that protects the components against overload, lightning surges, etc.
