The product description Data download

TBEA central inverters have been widely used in hundreds of large-scale ground and water surface pv power plants globally. The product power covers 500kW~5000kW. With its advanced topology, excellent output filter design, efficient MPPT strategy, DPWM technology with minimum switching loss, reliable heat dissipation design, and perfect protection functions, it can bring long-term stable benefits to pv power plants.

Technical advantages

1.Efficient power generation:
One MPPT for four inputs, I-type three-level power topology,
Inverter maximum efficiency greater than 99%, European efficiency greater than 98.7%
2.Investment saving:
Large array, Saving upfront investment,
Copper bar connection reducing the difficulty and cost of construction on site
3.Highly integrated:
DC side maximum 1.4 times over-matching access,
AC side 50 °C 1.1 times long-term overload operation without derating, To ensure power generation
