Sphere MC4 Inline Solar Fuse — 10A or 20A
MC4 inline solar fuse — protect your panels and wiring from overload and short circuit
SPHERE MC4 Solar Fuse: SPHERE MC4 Solar Fuse 10A
Why this product?
Without inline fusing between solar panels and your system, a short circuit or overload can damage your panels, cables and controller. MC4 inline fuses provide simple, compliant protection.
- Protects panels and wiring from short circuit
- Pre-fitted MC4 connectors — easy installation
- Available in 10A and 20A
- Calculate correct size: panel watts ÷ voltage = amps
- UV resistant outdoor construction
- PV/SOLAR grade compliant
About this product
Streamline your solar connections with our MC4 (the industry-standard weatherproof connector used on solar panels) inline fuses. Find the right fit for your application by calculating amps: panel wattage divided by voltage.
For example, a 200W Twin Cell Panel (200W ÷ 12V = 16.7A) requires a 20A fuse to safeguard against potential spikes.
Protect your equipment with ease!
Why this beats the alternatives
Pre-fitted MC4 connectors make installation fast and clean — no wire stripping or crimping required. Available in 10A and 20A to suit different panel configurations
Who it's for
Anyone building or expanding a solar system who needs to add compliant fusing between panels and controller — particularly when using branch connectors for multiple panels.
