Solar Inverter Series Inverter

Series inverters have become the most popular inverters in the international market. Series inverters are based on the modular concept, each PV series (1kW-5kW) through an inverter, with the maximum power peak tracking at the DC end, and parallel grid connection at the AC end. Many large photovoltaic power plants use string inverters. The advantage is that it is not affected by the module difference and shading between the series, and reduces the optimal working point of the photovoltaic module.
Mismatch with the inverter, thus increasing the power generation. These technical advantages not only reduce the system cost, but also increase the reliability of the system. At the same time, the concept of "master-slave" is introduced between the groups, which makes several groups of photovoltaic groups linked together in the case that the system can not make a single inverter work in a single series of electrical energy, so that one or several of them can work, thus producing more electrical energy. The latest concept for several inverters to form a "team" to replace the "master-slave" concept, making the reliability of the system a step further.
