ROSA G1 uses advanced control algorithms to implement an integrated energy management system in PV system to control and optimize energy flow. The hybrid inverter has both LED local monitoring and EMS system remote control functions, with excellent load adaptability and grid adaptability. In addition, the good hardware design makes it effective to deal with a variety of complex application environments, making system operation safer, more reliable, more economical, and more adaptable to the environment.
On-grid and off-grid dual output, can drive air conditioning and other inductive loads, and off-grid switching time can be less than 20ms to realize uninterrupted power supply
Adaptable to lithium batteries, batteries and PV/AC system are isolated by high frequency transformer, which is safe and reliable
Bidirectional DCDC can greatly reduce switching loss and improve charging/discharging efficiency due to resonant soft-switching ZVS technology and synchronous rectification technology
Compatible with wired CTs and meters for anti-reverse flow to protect power grid from pollution
