General Details
The world’s first daisy-chain single unit microinverter with extremely wide DC input operating voltage range (16-60V) and low start-up voltage (22V only). Hoymiles single unit microinverter MI-250/MI-300 is the perfect selection for PV system with uneven number of panel numbers with world’s No.1 CEC weighted efficiency – 96.5% (peak efficiency – 96.7%) in 2015.

Safer

  • Up to 60V DC input voltage (natural rapid shutdown) to guarantee no electric shock & fire risk on rooftop

Stronger

  • Module-level MPPT to ensure 10-30% more energy harvest compared with string inverter

Smarter

  • 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
