SMA String Inverter

This whole string will then be wired into the inverter.Central inverters are much larger than string inverters. Sizes may range from 125 kW to 2.5 MW, with even the smallest variants much larger than the biggest string inverters. Weights can reach many tons at the high end. The 2.5 MW variants can be ordered with or without transformers.The main advantage of a string inverter is that you only need one of them to convert the DC electricity coming from your solar array to AC power. If anything is going to fail in a solar system, it is likely to be the inverter - making troubleshooting relatively easy when things go wrong.A device used with solar arrays to convert the energy that is generated (Direct Current) to usable electricity for a home (Alternating Current). They are connected to multiple solar panels forcing the performance to be equal to the worst performing panel.
