⚡ REDEFINE YOUR BUILD SPACE: THE ALL-NEW GEN 2 SUPERSLIM SERIES IS HERE! ⚡

Stop sacrificing precious floor space or canopy storage just to get massive power. Engineered right here in-house in Welshpool, WA, our completely redesigned Generation 2 SuperSlim batteries pack high-end capacity into an ultra-thin, optimized profile built to survive the brutal Australian outback.

Whether you need the compact agility of the SuperSlim 160 or the heavy-hitting powerhouse capacity of the SuperSlim 300, here is why the Gen 2 series changes the game for custom 4WD, marine, and caravan builds:

🔹 Precision Low-Profile Sizing:

SuperSlim 160: Body measures 490mm (L) x 490mm (W) x 65.5mm (D) [570mm W x 530mm L x 65.5mm H with brackets & terminals].

Are your low-voltage fuses actually protecting your system... or just giving you a false sense of security?

When it comes to 12V, 24V, or 48V off-grid setups, wiring a fuse in isn't just about matching an operating amp rating and calling it a day. Not all fuses—and not all locations—are created equal.

If your fuse type or Interrupt Capacity doesn't match the specific demands of that section of your circuit, it can fail catastrophically when you need it most.

Let’s break down why location and chemistry dictate your fuse choice:

1. Parallel Lithium Batteries (High Fault Current, AIC Limits & Mounting)

The Challenge: Modern lithium (LiFePO4) battery banks have extremely low internal resistance. When wired in parallel, they can deliver massive short-circuit currents—often thousands of amps in a fraction of a second. Standard automotive or low-cost fuses can arc over and keep conducting electricity during a severe fault.

The Hard Limit (MRBF vs. Class T):

An MRBF (Marine Rated Battery Fuse) is a fantastic, compact solution for 1 or 2 batteries, but it is strictly limited to 10,000 AIC (Amperage Interrupt Capacity) at 14VDC.

Once you scale up to 3 or more batteries in parallel, the cumulative short-circuit current exceeds that 10,000A threshold. If a severe fault occurs, an MRBF can fail to extinguish the arc and effectively bypass the blown fuse. For 3+ parallel batteries, you must use a high-AIC Class T fuse.

The Mounting Rule: MRBF fuses must use a proper terminal fuse block/holder. You cannot bolt an MRBF directly onto a battery terminal stud by itself; without the dedicated holder separating the connections, the fuse body would be completely bypassed by the conductive battery bolt or stud. By contrast, Class T fuses require a dedicated fuse block/holder mounted inline (ideally within 30cm of the battery terminal).

2. Inverters (High Continuous Load & Surges)

The Challenge: Inverters draw massive continuous current under heavy loads and face huge inrush/surge currents when starting inductive loads (like compressors or air conditioners).

The Requirement: The fuse needs to handle these surges without nuisance-blowing, while still protecting the heavy-gauge battery cables. Typically, robust MEGA or ANL fuses mounted close to the power source are used, sized strictly according to the cable's safe ampacity.

3. Solar Panels to Solar Controller (The PV Side)

The Challenge: Solar arrays operate at much higher DC voltages (VOC) compared to your 12V/24V house bank, and standard 32V automotive fuses will fail dangerously if exposed to high-voltage DC faults.

The Requirement: You need dedicated Photovoltaic (PV) DC fuses and inline holders rated for the specific open-circuit voltage of your panel string, especially when panels are wired in parallel configurations where back feed current can become an issue.

4. Solar Controller to Battery (The Output Side)

The Challenge: This run steps down voltage to match your battery bank while handling the maximum output current of your MPPT charger.

The Requirement: This fuse protects the cable running from the controller to the Busbar or battery against shorts. It needs to match both the maximum output rating of the controller and the safe ampacity of the wire.

🤔 How is your rig set up? Have you matched your fuse types and Interrupt Capacities to the real-world fault currents of your system, or are you running a one-size-fits-all approach?
