We are the exclusive SW Distributor for Hoymiles Inverters.

McCune Solar Works supports our fellow solar companies by supplying the lowest cost, best quality equipment. We are now the exclusive SW distributor for Hoymiles Micro Inverters, the highest quality, lowest cost, most reliable inverters in the world.

In an effort to elevate our solar industry nationwide and to provide higher quality, lower cost equipment we are instituting a cooperative discounted buying opportunity for all solar installers to take advantage of container volume purchasing together as a group. All companies will be treated equally as to price, delivery and service. We will help you to become more profitable. The installations will be less costly in labor and equipment, more reliable, with lower O&M costs, and improve LCOE and cash flow. The Hoymiles microinverters have an MPPT efficiency of 99.8% and almost zero failure rate (0.18%). They are suitable for commercial and even utility scale projects, cost less than string inverter, optimizer, and other microinverter installations. No good reason to install anything else.

Please use the contact form “Get in Touch” to convey your interest or questions. We will have demonstrations, purchase meetings, and training events in the coming weeks.

Commercial, Industrial and Utility Scale

3.6MW AC Coupled MicroInverter – Asia

Unless a Hybrid Inverter is specified, there is no longer any reason to install a string inverter array. Hoymiles Microinverters have achieved parity in cost with string inverters. Now even Utility Scale AC coupled microinverter installations are not only easier and less expensive but Module Level Monitoring and Control is possible as well. Ease of installation with standard electrical equipment and wiring methods brings down installation costs for faster commissioning and ease of  O&M.

Residential

Hoymiles Microinverters with a failure rate of less than 0.18% are far more reliable than the leading microinverter in the USA market, in fact less costly and more reliable than any other microinverter or optimizer.

SAFER – SMARTER – LIGHTER – MORE POWERFUL – MORE RELIABLE

“The World’s First Single-Phase Microinverter” designed for 4 solar panels with dual MPPTs, with wide DC input operating voltage range(16-60V) and low start-up voltage (22V only).
Hoymiles 4 in 1 microinverter MI-1000/MI-1200 is “The Best Power Density Microinverter” ever in solar industry with extremely light weight – only 3.75kG including integrated DC & AC cables; 3-phase wiring makes it easy to be configured by Hoymiles 4 in 1 microinverter for MW size industrial/commercial PV power stations (one the world’s biggest microinverter projects configured by Hoymiles microinverter is 3.6MW).
  • 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-level 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
