Home Solar Inverter

When configuring the inverter, we should pay attention to two aspects: 1. The voltage after the series of multiple components is the sum of the voltage of each component. The working voltage is about the rated working voltage of the inverter, with the highest efficiency For example, 3KW inverter, with 260W components, working voltage 30.5V, with 12 pieces of working voltage 366V, power is 3.12KW is the best 30KW inverter with 260W components, connected with 126 components, each road 21 strings, voltage is 640.5V, the total power is 32.76KW is the best 2. The maximum limit open-circuit voltage after series assembly does not exceed the maximum voltage of the inverter, such as 270W components, open-circuit voltage is 38.3V, open-circuit voltage temperature coefficient is -0.32%/ degree, if at -25 degrees,24 blocks in series, the final open-circuit voltage V=38.3[1+(-25-25)*(-0.0032)]*24=1066V

Have a nice day!
