With the development of technology, we are developing systems that allow us to use natural resources in our homes. One of these is a solar inverter. Utilising solar light is a great way to reduce the electricity bill and, at the same time, be environmentally friendly. We have included information about solar inverters to help get you started.
What does a solar inverter do?
A solar inverter is a power conversion device that processes the voltage from a direct current (DC) source into an alternating (AC) voltage. The device is usually attached to the roof or a wall. Solar photovoltaic panels (PV) convert sunlight into electricity allowing the safe use of electrical appliances in homes and workplaces.
There are multiple types of solar inverters. Below are the six common ones.
Types of Solar Inverters
1. String Inverter
This inverter is installed on the wall or close to the house and connected to many solar panels. It is popular because it’s simple to use and relatively affordable. The PV system is also standard in design and suitable for home use.
2. Micro Inverter
Each panel in this system has a micro inverter. Panels and inverters are in different compartments, and there is a combined AC solar module. Unlike string inverters, a failure in one panel does not prevent the efficiency of other panels. Because it provides AC power instead of DC, there is no fire risk.
3. Battery Inverter
A battery inverter, different from the first two inverters, turns the DC electricity in the battery into AC electricity for use in the home or workplace. Solar energy is stored and collected in the battery. These inverters charge faster and generate strong currents.
4. Hybrid Inverter
The hybrid inverter system has an accumulator, which is an energy storage device connected to solar energy, so you will need a battery. It works even when there is no power.
5. Grid-tie Inverter
This is a subset of inverters. The purpose of these inverters is to allow solar energy into the electricity grid. Most string, hybrid, and micro inverters are also in this subgroup of inverters.
6. Off Grid Inverter
This inverter is an independent inverter group fully compliant with diesel-generated electricity.
What to consider when buying an inverter
Some technical things to think about are:
- Inverter Size: This usually depends on the size of your solar panels. Inverters are sized by calculating in Kilowatts (Kw). The amount of solar energy production is calculated by rating in Kw. Choose an inverter size according to the solar panel system.
- Inverter Efficiency: An efficiency inverter uses the conversion of electricity from DC to AC. Most inverters have an efficiency of 95 per cent, with some reaching 98 percent.
- Inverter Warranty: Inverters have warranty periods ranging from 5 to 10 years. Installation labour usually has a 10-year warranty. But extra payments can also be made for a longer warranty period.
- Solar Monitoring Technology: Inverters with newly developed smart technology can monitor many features such as electricity production efficiency, solar battery charge and the amount of electricity in the grid.
You may be a little confused when you analyse all this information. A solar expert can help you decide which inverter is best, so be sure to contact one before buying a solar inverter.
