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.

Off grid living!

The system has been easy so far to assemble and install. One of the 36 solar panels had 3 shifted cells that seem to be off due to manufacturing and had to drill some holes with the structure otherwise all seems perfect.

Reliable off grid/backup power!

Couldn’t be happier with this complete kit. I have the smaller battery bank 2 hsky 5.3kwh each. I am using this system fully off grid (for now...maybe indefinitely). It runs my RV, well pump and all my other power needs with ease. I installed the system myself and the only problem I ran into is that the battery cables from the inverter to the battery combiner box were too short to install in a wire trough setting. But I was able to get longer 2/0 battery cables online for under $100 so NBD. The sol ark is really user friendly and has amazing capabilities. GET THIS KIT!
