Discover the Advanced XG3KTL-S Single Phase On-Grid Solar Inverter by INVT
In the evolving landscape of renewable energy, on-grid solar inverters play a pivotal role in converting solar power into usable electricity for homes and businesses. Among the leading products in this category, the XG3KTL-S Single Phase On-Grid Solar Inverter by INVT stands out due to its innovative features, robust performance, and intelligent design.
Maximizing Efficiency for Higher Revenue
Efficiency is a key factor in the performance of any solar inverter, and the XG3KTL-S excels in this aspect. With the capability for 150% DC input oversizing, this inverter allows for a higher input of solar energy, ensuring that even under less-than-optimal sunlight conditions, it can maximize the conversion of solar power into electrical energy. This feature is crucial for increasing the overall energy yield, which translates directly into higher revenue for system owners.
The wide Maximum Power Point Tracking (MPPT) voltage range of 50V to 550V is another significant advantage. This broad range ensures that the inverter can operate efficiently across a variety of conditions, capturing the maximum possible energy from the solar panels throughout the day. Additionally, the inverter supports a maximum input current per string of 20A, making it compatible with high-power modules. This compatibility allows for flexible system design and the integration of advanced solar panel technologies.
