A System Fault refers to a malfunction or failure in the Selective Catalyst Reduction system of a vehicle. The SCR system is responsible for reducing emissions by injecting diesel exhaust fluid (DEF) into the exhaust stream to react with nitrogen oxides (NOx). When a System Fault occurs, it indicates a problem that requires attention. Use the following steps for proper installation: Loosely assemble all of the components. Ensure heatsink thermal compound was used on the SCR Pole Faces. Finger-tighten the two Clamp bolts. Verify the top and bottom mounting surfaces are parallel to each other, like shown in Figure 6, not as shown in Figure 5.

This is where a derate comes in. To fit the 50A solar breaker, we can sometimes reduce the power rating of the main breaker. If we reduce the size of the main breaker to 100A, then we have 50A available to add solar. 100A main breaker + 50A solar breaker = 150A. This 150A follows the 120% rule, and a main panel upgrade has been avoided!
