Risen Titan S RSM40-8-400M (400 W)
The Risen Titan S RSM40-8-400M is a 400 W solar module built on Mono PERC technology (Monocrystalline PERC (Passivated Emitter Rear Cell)). It delivers a maximum-power voltage (Vmp) of 34.2 V at a maximum-power current (Imp) of 11.7 A, with an open-circuit voltage (Voc) of 41 V and a short-circuit current (Isc) of 12.3 A under Standard Test Conditions (1000 W/m², 25 °C, AM1.5G). Conversion efficiency is 20.4% across a 1903 x 1130 mm footprint.

Technology & Performance Notes
Mono PERC is a workhorse mainstream technology with excellent bankability and low $/W. At 20.4% module efficiency the Risen Titan S RSM40-8-400M converts 20.4% of incident solar irradiance into DC electricity, putting it in the mainstream efficiency tier for its class. The 186.0 W/m² power density determines how many watts fit on a given roof or field area.
String Sizing & System Notes
When wiring the Risen Titan S RSM40-8-400M 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 (12.3 A) with the standard 1.25x safety factor.
