☀️ Advanced MPPT Solar Charging

MPPT technology continuously monitors the output of your solar array and adjusts its operating point to help extract the maximum available power under changing conditions.

Solar output can vary throughout the day due to:

• Sun angle
• Cloud cover
• Panel temperature
• Partial shading
• Battery voltage
• Changing electrical loads

An MPPT controller dynamically responds to these conditions to optimise solar energy harvesting.

⚡ Powerful 80A Charging Capacity

With up to 80 amps of charging current, the MPPT80 is designed for significantly larger systems than typical entry-level solar regulators.

This makes it particularly suitable for installations containing:

• Large lithium battery banks
• Multiple solar panels
• High daily power consumption
• Large caravan electrical systems
• Off-grid battery storage
• High-demand touring setups

An 80A controller provides substantial charging capacity for systems where fast recovery of a large battery bank is important.

🔋 Ideal for Large Battery Banks

Large-capacity batteries require sufficient charging current to restore energy efficiently after heavy use.

The Razorback MPPT80 is an excellent choice for battery systems powering equipment such as:

• 12V fridges and freezers
• Inverters
• Lighting
• Water pumps
• Fans
• Communications equipment
• Camping appliances
• USB and accessory outlets
• High-demand 12V equipment

🚙 Ideal for 4WD & Canopy Solar Systems

Modern touring vehicles can carry significant electrical loads, particularly when fitted with large lithium batteries, inverters and multiple accessories.

The 80A MPPT Solar Controller is ideal for high-capacity 4WD installations including:

• Touring canopies
• Dual battery systems
• Large auxiliary battery banks
• Rooftop solar systems
• Portable and fixed solar arrays
• Off-road camper systems

🏕️ Perfect for Caravan & Motorhome Solar

The MPPT80 is also well suited to larger caravan and motorhome solar installations where significant battery capacity and daily electrical consumption require strong solar charging performance.

Ideal for powering systems running:

• Compressor fridges
• Inverters
• Lighting
• Pumps
• Entertainment systems
• Communications equipment
• General 12V accessories

🌊 Marine & Off-Grid Applications

The high charging capacity also makes the MPPT80 suitable for larger marine and remote-power installations.

Common applications include:

• Boats
• Marine battery banks
• Remote cabins
• Off-grid sheds
• Mobile workshops
• Remote communications
• Solar battery storage
• Commercial touring vehicles

📈 Built for Larger Solar Systems

A high-current controller allows larger solar systems to be designed around higher daily energy requirements.

This is particularly useful where:

• Battery capacity has been increased
• More solar panels have been added
• Inverter use is significant
• Daily electrical consumption is high
• Faster solar recovery is required

Correct solar-array sizing is essential to ensure the controller operates within its specified electrical limits.

🛡️ Correct System Protection Matters

High-capacity solar systems can carry significant DC current.

For a safe and reliable installation, always use:

• Correctly sized solar cable
• Correct battery cable
• Appropriate fuses or circuit breakers
• Secure cable terminations
• Correct polarity
• Properly rated isolation equipment

Always follow the manufacturer's electrical specifications when sizing the solar array and battery wiring.

🧰 Installation Difficulty

🟠 3/5 – Intermediate

An 80A MPPT controller is designed for substantial solar installations and requires correct system design.

Installation should consider:

• Solar panel configuration
• Maximum PV input limits
• Solar-array open-circuit voltage
• Battery voltage
• Battery charging requirements
• Cable size
• Fuse and circuit-breaker ratings
• Cable length
• Correct polarity

Professional installation is recommended if you are unfamiliar with high-current DC solar systems.

  ⚠️ Important Solar System Sizing

  Always confirm your solar-panel configuration, battery voltage, maximum PV input voltage and allowable solar-array size against the MPPT80 manufacturer's specifications before installation.

  The total solar-array open-circuit voltage (Voc) must remain within the controller's specified limits under all operating conditions.
