Microinverter Power Performance Test
The current Hoymiles HM Series microinverters we are using in our installations are 3% more powerful than other leading market competitors. So do they perform as well as the manufacturer claims? Read on to find out!
The Microinverter Power Performance Test
We conducted the microinverter AC power performance test using two high precision DC variable voltage power supplies to simulate the solar power, feeding on average 325W DC to each channel of a Hoymiles 600W dual channel microinverter. Then we measured the peak power output with a third-party certified energy meter, the Brultech Green Eye Monitor (GEM). This is the same energy meter used by the Nova Scotia Community College Applied Energy Research Lab for researching purposes.
DC Power Supplies
The objective of this test was to stress the microinverter by making it work at its max power output, verifying in real-time the AC power produced, while also measuring the accuracy of the Hoymiles monitoring system.
The Results of the Microinverter Power Performance Test
Peak AC power output of the Hoymiles MI-600 is rated at 600W (300W/channel).
According to the Hoymiles monitoring system, the inverter was feeding 611.4W into the grid, around 2% more than expected:
The Brultech Green Eye meter recorded a stable AC power production of 609W, around 1.5% more than expected:
Brultech Meter Reading
The difference in the values registered by the Hoymiles monitoring system and the energy meter was only 0.4%. This is a high grade of accuracy, given that the monitoring system is not considered “revenue grade”, and gets its information via Zigbee wireless technology.
So there you have it! The results of the microinverter power performance test shows that the Hoymiles microinverters we use produce more power than expected. And when paired with the premium LG solar panels that produce 5.6% more power than competitors (as we found in our Solar Panel Performance Test), choosing SKYLIT as your solar provider means you’ll have a top of the line, high performance system that is built to last!
