Product Highlights

Hoymiles single unit microinverter MI-250/MI-300 is the perfect selection for PV system with uneven panel number 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
