Solar inverters are electronic systems used to convert the variable DC output of solar panels into AC which is on a frequency that most applications and devices use. Inverters are typically set up outside on factories, homes and offices, so they can directly be exposed to sunlight, constantly. The typical solar inverter is made up of 4 components – a solar panel, a battery, an inverter and charge controller.
The inverter is an indispensable part of the inverter system, and without it the panel wouldn’t be able to produce the AC by itself. Solar inverters consist of capacitors that are large in size, which help in storing the usable power, as well as improving the output of the inverter itself. Even though the conventional ones are the same as solar inverters in terms of their basic usage, the main difference between them is the circuit composition.
Solar inverter parts include a terminal connected to the battery, and a solar charge controller. The inverter reduces the amount of electricity the user consumes, and hence, the money the user spends on paying utility bills. That being said, considering the quality of the solar inverter parts will ensure you get the right one that will satisfy your needs.
The life-span of the inverter itself will be determined by the quality of the battery. For that reason, choosing the right battery is not something you should take lightly. Battery capacity is defined by the amount of watts it can produce in a certain amount of time. In other words, it’s defined by the maximum amount of hours it can power all devices connected to the solar system.
Inverters typically come in various power ratings. The surge indicates the amount of watts that go over the inverter’s capacity. This is important when starting up devices, equipment and appliances that have a start surge like power tools, for example. The surge rating can vary between inverters, even if they’re made by the same manufacturer. Most devices can typically be covered by a rating that varies anywhere between a 4 and 15 seconds.
Solar inverters need to supply both peak and typical power. Peak power is the amount of power the inverter can supply for small time periods. This is closely related to the power surge ratings of inverters. Typical power on the other hand, is the usual amount of power the inverter can supply constantly, once devices start up and require a stable surge of power.
