KickAss 40A 12V/24V/36V/48V MPPT Solar Charge Controllers Features Overview

The KickAss 40A 12/24V MPPT Solar Controller uses the latest dual-peak and multi-peak tracking technology available today.

Highly Efficient MPPT

With a tracking efficiency of at least 99.5% and a peak conversion efficiency of 98%, you can be confident that your dual battery system is receiving the optimal charge.

The KickAss 12/24V MPPT Solar Controller series accurately identifies and tracks multiple power points, and includes built-in self-diagnostic technology to help prevent damage from installation and system failures.

Battery Temperature Sensor

Equipped with a temperature sensing probe, the KickAss 12/24V MPPT Solar Controller can limit the current output to your battery, preventing overheating and overcharging if a fault occurs with the connected battery.

LCD Display

The easy-to-read LCD display shows all crucial charging information dynamically (note that the LCD is not backlit).

Pair with

• KickAss Remote Control LCD Display For MPPT Controllers
• KickAss Bluetooth MPPT Module

These devices allow for convenient viewing of your controller in tight spaces and can connect to the KA Solar App on your smartphone for added convenience.

**Please Note: this unit is not a full battery management system, it is simply an MPPT with a load output**

Do not get the controller wet, as it is not waterproof and will be damaged by moisture.

This device is a charge controller, not a complete battery management system. It is designed to power small accessories like LED lights. However, the load output is dependent on the solar input (daylight and darkness) and does not provide a consistent power supply suitable for running appliances like a fridge or freezer. Therefore, we advise against connecting electronics that need stable and reliable power directly to the MPPT Solar Controller. Instead, all accessories should be connected directly to your battery bank using appropriately fused circuits.

x2 Anderson to Bootlace Ferrule Connectors Included
The unit comes with x2 Anderson to Bootlace Ferrule Connectors – the Anderson plug makes setup simple, while the bootlace ferrule ensures a clean, secure fit into the controller’s terminals.

 

The KickAss 40A MPPT Solar Charge Controller supports 12V, 24V, 36V, and 48V nominal system voltages and is compatible with GEL, FLD, AGM, USER, and Lithium battery types. It automatically or manually configures these settings to suit your battery system.
This flexibility means you can use the controller with a wide range of battery setups, ensuring optimal charging performance for your off-grid or adventure power needs.

The KickAss 40A controller can handle a maximum solar input power of up to 2400W at 48V systems and provides a rated charging current of 40A. It maintains a high conversion efficiency of over 98% and MPPT tracking efficiency above 99%.
This means your solar panels will be utilised efficiently, delivering maximum power to your batteries while protecting your system from overload.

You can configure the battery type and nominal system voltage directly via the integrated LCD display or remotely using the KA48MPPTRC remote display. Settings include GEL, FLD, AGM, Lithium, and user-defined battery types for 12V to 48V systems.
This intuitive setup process ensures your controller is optimised for your specific battery chemistry and voltage, maximising battery life and charging efficiency.

The controller includes integrated aluminium heat sinks for heat dissipation, prevents reverse polarity connection of lithium batteries, and requires appropriate wiring and fusing for safe operation. It also has a common negative design for proper grounding.
These built-in protections and design choices keep your system safe and reliable, even under demanding off-grid conditions, giving you peace of mind during use.

Yes, the controller supports RS485 communication and comes with an integrated Bluetooth interface, allowing remote monitoring and configuration via the KA48MPPTRC remote LCD display.
This feature lets you easily check system status and adjust settings from a convenient location, making system management straightforward and user-friendly.

The KickAss 40A controller measures 218mm x 150mm x 65mm and weighs 1.9kg. It requires an installation area of 205mm x 60mm with 5mm x 5mm mounting holes.
Its compact size and moderate weight make it easy to install in various off-grid power setups without taking up excessive space.

The controller operates reliably between -35°C and +45°C and has an IP43 ingress protection rating, suitable for typical off-grid and adventure environments.
This robust design ensures consistent performance in harsh outdoor conditions, making it ideal for Australian off-grid use.

The KickAss 40A controller features MPPT tracking efficiency greater than 99% and overall conversion efficiency above 98%.
High MPPT efficiency means the controller extracts nearly all available power from your solar panels, maximising energy harvest and reducing charging times, which is essential for reliable off-grid power.
