The First Single-Phase Microinverter designed for 4 solar panels with dual MPP Ts, with wide DC input operating voltage range (16-60V) and low start-up voltage (22V only).
 AROSI 4 in 1 microinverter A-1000/A-1200 is "Power Density Microinverter" in solar industry with extremely light weight-only 3.75Kg, including integrated DC &AC cables;
3-phase wiring makes it easy to be configure for MW size industrial/commercial PV power stations (one the world's biggest microinverter projects configured by AROSI microinverter is 3.6MW).

Up to 60V DC input voltage (natural rapid shutdown) to guarantee no electric shock & fire risk on rooftop
Module-level MPPT to ensure 10-30% more energy harvest compared with string inverter
Module-lever monitoring for remote troubleshooting & maintenance management
Smaller, Lighter & Easier
Smaller than A4 paper size, 1.98kG only with AC cable (1 m) integrated, one person’s easy installation
More stable & reliable
6000V surge protection, MTBF (mean time between failure) > 550years, yearly failure rate < 0.18%
Better Payback (IRR)
Module-level solution, extremely low failure, longer generation(star-up voltage 22V only), low LCOE (Levelized Cost of Electricity)for long period 
(20+ year) of investment
