ROSA G2

ROSA G2

Single Phase Hybrid Inverter

230A Charge | 2x Overload | IP66 | Parallel

  • 230A high-current charge/discharge—shorter charging time, eliminating power shortage anxiety
  • 200%(2x)support for two-times transient overload, providing stronger load adaptability
  • Flexible parallel expansion—supports multiple unit connections for easy capacity expansion
  • Low-voltage wake-up—PV low voltage forces the battery to wake up,improving stability and extending power supply duration
  • Smart APP monitoring-remote monitoring with convenient operation
  • IP66-rated design —dustproof and waterproof,ensuning long equipment life
