Introduction
Our Three Phase Dual MPPT On Grid Solar Inverter is tailored for the needs of industrial and commercial solar applications, delivering a robust power output of 50~60kw. It's engineered to power large-scale solar systems while maintaining high efficiency ratings of up to 99%, significantly reducing energy expenditure. Safety is also a priority, with an inbuilt protection mechanism that ensures the inverter remains secure in case of failure. Additionally, the inverter comes equipped with protection features like lightning protection, short circuit, overcurrent, and reverse connection, making it a reliable tool in any power system.

This three-phase grid-connected inverter is a reliable and efficient solution for converting DC power into AC power through photovoltaic strings, which is then fed into the grid. With the help of its dual MPPT (Maximum Power Point Tracking) design, the inverter optimizes the performance of solar modules even in low sunlight conditions. This helps to ensure maximum power generation efficiency. The inverter can track the maximum power point of two sets of solar panels, which is useful when one or more of the panels are shaded and their output capacity is reduced. In such cases, the inverter automatically switches to another MPP point, thus ensuring that the solar panels generate the maximum amount of power possible. This feature makes the three-phase dual MPPT on-grid solar inverter an ideal solution for a range of applications, including home and commercial installations.
The Three Phase Dual MPPT On Grid Solar Inverter, with its bi-directional interface design, offers versatility in a variety of scenarios. This inverter has a power storage capacity that can be utilized in Time-of-Use electricity rate environments, allowing users to release stored power during the low valley periods. Other devices can also be used with the inverter to supplement or feed back into the grid. Additionally, this device supports remote configuration and upgrades through an APP, providing users with real-time monitoring capabilities. With a maximum string current of 15A, the inverter can deliver up to 110% of overload output making it an ideal choice for large industrial and commercial environments.
