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.

Coming together!

Customized the WHK3 with second SolArk, second Kong 19kwh and double the panels. Everything arrived in a reasonable amount of time… still waiting on my ground mount that was ordered from a different company! :(

Shopsolarkits has been great!
