Detail
Creative MPPT tech makes efficiency higher than 99%. Peak conversion 80%. Consider the conversion rate of solar panel is about 80%, for example, if you need 500W power output from the inverter, you need to connect it to a solar panel that 500 / 0.8 / 0.8 equals about 780W, (780w * 0.8 * 0.8 = 500w)
10.8V/30V is not the working voltage? Why should the advertisement display DC10.8-30V?
Y&H grid tie inverter is designed for solar panels. The working voltage of solar panels depends on the intensity of sunlight, which means that the panel voltage varies. There is also an increase in the voltage at the moment the solar panel starts.
When you use a 12V solar panel, the working voltage of the panel is 18V-21V. But the moment of starting is to reach 24V or higher. We design 30V to buffer the instantaneous voltage at startup.
When the sun is weak. The panel voltage drops from 18V to 17V, 16V, 15V... 10.8V. We design compatible wide voltage input in order to obtain more power output. Of course, as the panel voltage decreases, the inverter output efficiency will decrease.
Put another way. DC10.8-30V input, the actual starting voltage is 15.5V. After starting. The lowest tracking voltage can reach 10.8V. This is the additional power obtained. Can be ignored. The main power acquisition is that the panel voltage is 18V-21V (when the sun is strong)
Y&H is an experienced research and development team, specializing in the manufacturing of solar inverters. With over 9 years of professional experience, we have become a thriving enterprise.
