Page 7: About Product
The Hoymiles HMT-2000-4T series microinverters are equipped with module-level monitoring, which collects microinverter data wirelessly and sends it to the Hoymiles monitoring platform, S-Miles Cloud. The HMT-2000-4T microinverter’s MPPT circuit is less susceptible to partial shading. With dual MPPT, the other MPPT can operate the unshaded string at maximum efficiency point when one MPPT fails or is shaded, ensuring the inverter delivers optimum performance under different partial shading situations. -
