F14 fault code

During the night the system failed. F14 is the code, from the app graphs I noticed a massive drop in SOC even though the load remained stable. What could cause this in such a short space of time?

When a F14 DC_overCurr_fault occurs, this likely means that the overcurrent protection device has detected an overcurrent situation and has taken action to protect the circuit.


Overcurrent is a situation where the current (the flow of electrical charge) in an electrical circuit exceeds its maximum allowable value. In DC circuits, this can occur due to a short circuit, overloading, or a device failure


When an overcurrent situation happens, it can generate excessive heat in the circuitry. This may cause damage to the components of the circuit, including the wiring itself.


Please contact your installer, or a qualified electrical engineer and investigate and identify the source of the overcurrent.
