Renogy 20A/30A/40A/100A ANL Fuse

The Renogy 20A/30A/40A/100A ANL Fuse Protects Your Controller, Wire and Battery From Overcurrent

The Renogy 20A/30A/40A/100A ANL Fuse is a replaceable ANL fuse for DC systems operating below 72V. It is made of alloy and brass copper, and it has a clear window so you can see whether the fuse has opened.

It is for anyone fusing a charge controller, battery, inverter or the wires that connect them. Pick the current rating that matches your circuit.

Renogy 20A/30A/40A/100A ANL Fuse Features

Overcurrent Protection for Your Equipment

Renogy says the ANL fuse protects your controller, wire and battery from overcurrent. The ratings are 20A, 30A, 40A and 100A, each for DC systems under 72V.

Clear Window Shows Open Status

A visible window lets you identify an open fuse at a glance. Renogy also states the fuse is ignition protected, for use in RVs, boats and other closed environments.

Corrosion-Resistant Terminal Contacts

The terminal contacts are gold and nickel plated for corrosion resistance. The fuse is RoHS compliant.

Made for the Renogy ANL Fuse Block

Renogy says the fuse is for use with its ANL fuse block, together with a clear protective non-conductive cover. The fuse can be replaced by itself when it blows.

Real-World Applications

Charge controller circuits. Fuse the cable between a controller and a battery.

Inverter and battery wiring. Protect the connecting wires from overcurrent.

RVs and boats. Renogy says the ignition protection suits closed environments such as these.

Practical Comparison

ANL Fuse Versus a Circuit Breaker

A fuse is replaced after it opens. A breaker can be reset. An ANL fuse is a simple, compact choice when you want a replaceable protection part with a visible window.

20A Versus 30A Versus 40A Versus 100A

All four ratings share a 72V voltage rating. They differ in the rated current and the interrupt capacity, so choose the one that matches your circuit.

Buyer Guidance

Match the Rating Exactly

Renogy says to use fuses with current ratings that exactly match the system's rated current, and to follow the fuse size in the manual for your charge controller, battery charger or inverter. Never use a substitute such as copper wire. Replace a blown fuse with an identical model.

Install With the Power Off

Disconnect all power before you replace a fuse, and wear insulating gloves. Renogy's manual lists 70.8 inch pounds (8 N·m) tightening torque for the nuts, with ring terminals sized for M8 studs. Fuse cables are sold separately.

This May Be A Good Fit If

• Your DC system runs below 72V
• You want a fuse you can check through a clear window
• You are using a Renogy ANL fuse block
• You need to replace a fuse without replacing the holder

Common Questions

Can I replace the fuse by itself?

Yes. Renogy says the fuse alone is replaceable. Replace the holder only if its terminals are damaged.

How do I size an ANL fuse?

Follow the recommended fuse size in the manual for your charge controller, battery charger or inverter. You can also size it from the current going through the fuse.

Does it come with a fuse cable?

No. Renogy says you need to buy a fuse cable separately.

What's Included

• 1 x ANL Fuse

Each option includes one fuse in the current rating you choose.
