Collection: LUX Solar Kits & Off-Grid Calculator

Do you enjoy spending hours researching what individual components, cable sizes and fuses you need? If so, add them individually to your cart. Otherwise, choose one of our kits - our backend algorithm matches all the components based on your selected solar wattage, carefully designed so that your system runs well and gets the most out of the sun's power. Our custom kit-builder allows you to fully customize your panel configuration, mounts, controller (including upgrading to Victron), inverter & more.  Download our DIY Installation Manual for installing our Solar Kits (email address required to download!)

Get things right the first time with LUX Solar's DIY Kit Size Calculator

There are two types of solar system. One where you guess a solar wattage, a battery size, a cable thickness, a fuse size and join it all together and pray to the sun gods that it works. 90% of people do this. We believe that a solar system should actually meet your requirements and be sized correctly for you. Save yourself the hard work of ripping out cables, buying a new controller, trying to match your old panel with a new one that's not sold anymore and get your system design right the first time.

Our calculator will recommmend a minimum size for your solar and battery - just enter your appliances or select an example scenario:
