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?…
