Technology & Performance Notes
TOPCon is the leading n-type technology for high efficiency with strong low-light and temperature behaviour. At 22.5% module efficiency the LONGi Hi-MO X6 LR7-54HVH-440M converts 22.5% of incident solar irradiance into DC electricity, putting it in the premium efficiency tier for its class. The 225.6 W/m² power density determines how many watts fit on a given roof or field area.
String Sizing & System Notes
When wiring the LONGi Hi-MO X6 LR7-54HVH-440M into a string:
- Keep the string Voc (temperature-corrected to the coldest expected cell temperature) below the inverter’s maximum DC input voltage.
- Keep the string operating Vmp within the inverter’s MPPT window across the expected temperature range.
- Size fusing and conductors against Isc (14 A) with the standard 1.25x safety factor.
