WWSPCS300 can be used for both on-grid and off-grid systems. Besides, it has adopted advanced LCD touch screen technology, and is easy to operate.
Features
▪ MPPT for wind turbine and solar power generation.▪ Applicable for not only on-grid system, but also off-grid system. And supportable for seamless switch between on-grid and off-grid.
▪ Support grid charging and diesel charging.
▪ Motor soft starting on off-grid state.
▪ Support three-phase 100% unbalanced output load on off-grid state.
