Disclaimer: Each solar kit includes solar-specific equipment to get you started, but please keep in mind that you may need to purchase additional items like installation tools, grounding rods/wire, and any AC components you might need. We highly recommend bringing in a certified solar installer or master electrician to help with the installation process to ensure a safe and reliable system that meets all relevant codes and standards. Also, if you purchase a solar kit without solar panels, you will be responsible for ensuring the compatibility and configuration of your solar panel array. Each solar kit includes professionally designed schematics that work within the parameters of each inverter. There are minimum and maximum input voltages with each inverter that you will need to be aware of so that you do not damage your inverter and/or void your warranty.
