The big brother to our SwitchMaster unit, e
mbrace innovation with SwitchMaster MAXI, meticulously designed and developed right here in Australia to redefine simplicity and efficiency in 12V systems management .


The SwitchMaster MAXI's 8x20A and 2x50A pre-fused outputs allows control of even the biggest systems. Hook up anything and everything - run multiple light circuits,  fridges, inverters, even large water pumps or air compressors - the possibilities are endless. Take control with ease through our user-friendly Apple/Android apps, or drop the phone entirely and control your SwitchMaster directly from your Apple Watch! For the ultimate peace-of-mind for the remote explorer, or those who are hestitant on completely relying on their phone, we have also integrated a small switch panel on the front panel of the unit and developed additional cabling options, enabling direct control of your SwitchMaster from existing 12v switch panels or any automotive or marine 12v switch. 


Much more than just a simple switch panel, the SwitchMaster can unlock the full potential of your 12V system. Group outputs together to allow you to switch multiple outputs with the touch of a button. Take it a step further with the voltage, current, and temperature sensors integrated into the SwitchMaster itself, offering cutting-edge automatic switching capabilities based on the conditions you set - a new standard in functionality, convenience and piece of mind. Automatically turn on an exhaust fan when your canopy reaches a certain temperature? Easy. Turn outputs on or off when a particular voltage is detected? No problem. Want to set low voltage cutouts individually per output instead of as a whole system? You've got it.


You can also say farewell to tangled wires and messy setups as the SwitchMaster arrives pre-fused and ready to install, catering to DIY enthusiasts and seasoned professionals alike. The SwitchMaster is also fully compatible with any charging system and battery chemistry. Seamlessly integrate it into your setup and discover a world of possibilities.
