Hybrid Inverter

12-18kW 丨3 MPPTs 丨LFP/VRLA

61.ROSA G2 场景改磨砂


Dust protection, impervious to water splashes

2.ROSA G2 (IP66)(1)

97.8% High Power Generation Efficiency: 560kWh more electricity generated annually 

Forced Wake-up: PV function forces waking up the battery 

230A Charging and Discharging Current: Shorter charging time, no more anxiety about drawbacks 

100~500V Photovoltaic Voltage: Low start-up voltage, 90 minutes of additional daily power generation 

30% Smaller in Size: Ample installation space, cost-effective transportation
