How to Find the Right Solar Inverter?

The modules produce direct current. Your electrical devices require AC power. That does not fit yet! To be able to use the solar power in the house (or to feed it into the grid), it has to be converted into AC (alternating current).

This is exactly what inverters do. They also control and monitor the entire system.

Which Solar Inverter you Should Buy?

The solar inverter depends on the power of the connected solar modules. Typical grid-connected house roof systems have at least one inverter, but often several – depending on the number of modules, system performance, configuration, and inverter type.

Which Voltage Converter do you Need for Small Systems?

Solar panels and charged batteries are known to supply direct current. However, normal technical devices in the household require alternating current. There are also these so-called voltage converters for mobile and small systems, which convert the DC into AC – from 12V or 24V to the required 230 volts.

How Much Power Does my Voltage Converter have to have?

This depends on the required device performance. So pay attention to quality when buying. With very cheap pure sine converters, the sine wave is sometimes not as clean as stated. That causes technical problems and you just get annoyed.

Tips for Use in PV systems:

The inverter should have good power control behavior. The larger the MPP voltage range, the better. Also, pay attention to the noise levels of the device. Installed in living rooms, the level of your inverter should be around 40 decibels.
