The Slocable solar panel MC4 fuse is an inline fuse connector that protects photovoltaic DC-side circuits. It integrates a fuse box with a standard MC4 connector, providing plug-and-play overcurrent protection. Its primary function is to prevent overheating and fire risks caused by reverse current or fault current in photovoltaic strings, making it a key component in enhancing the safety level of photovoltaic systems.
Specialized Core
Utilizing a fuse designed specifically for photovoltaic DC circuits, it boasts a full-range breaking capacity, safely and reliably interrupting all types of overcurrent, including short-circuit currents.
Fully Certified
Our MC4 inline fuses are certified by international authorities such as TüV, CE, and UL, meeting the most stringent safety regulations and ensuring reliable quality.
Excellent Contact Design
Internal metal components utilize tin-plated copper for excellent conductivity and low contact resistance, ensuring long-term operation at rated current without overheating.
Durability
Flame-retardant rating of UL94-V0 is achieved, and the housing is rugged and durable, ensuring long-term outdoor use without deformation or degradation.
Flexible Supply
Available in a variety of mainstream current specifications (2-30A), with replacement fuse cores available to reduce ongoing maintenance costs.
PV Systems with Optimizers:
Each optimizer module must have an MC4 inline fuse connected in series with the positive or negative output terminals to isolate faults.
Multi-String-Parallel Systems:
When multiple strings are connected in parallel to a single inverter, installing a solar fuse in the output circuit of each string can prevent circulating current loss and fault propagation between strings.
PV Energy Storage Systems (DC Coupled):
In the battery's DC charge and discharge circuits, MC4 fuses serve as overcurrent protection devices to prevent high current surges caused by short circuits and other factors.
Rooftop PV, solar carports, building-integrated photovoltaics (BIPV), etc.
