Maxeon 5 SPR-MAX5-400 (400 W)
The Maxeon 5 SPR-MAX5-400 is a 400 W solar module built on IBC technology (Interdigitated Back Contact (IBC)). It delivers a maximum-power voltage (Vmp) of 34.1 V at a maximum-power current (Imp) of 11.73 A, with an open-circuit voltage (Voc) of 40.6 V and a short-circuit current (Isc) of 12.2 A under Standard Test Conditions (1000 W/m², 25 °C, AM1.5G). Conversion efficiency is 22% across a 1872 x 1041 mm footprint.

Technology & Performance Notes
IBC is a high-efficiency back-contact technology that keeps the front face free of shading metal for a sleek all-black look. At 22% module efficiency the Maxeon 5 SPR-MAX5-400 converts 22% of incident solar irradiance into DC electricity, putting it in the premium efficiency tier for its class. The 205.1 W/m² power density determines how many watts fit on a given roof or field area.
String Sizing & System Notes
When wiring the Maxeon 5 SPR-MAX5-400 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 (12.2 A) with the standard 1.25x safety factor.
