What these labels mean
Likely compatible: confirm with seller
Within the size limit, and we have seen a lab certificate for the kit’s inverter. The law asks for lab certification without naming a standard, so confirm with the seller that the whole kit qualifies.
Component certificate only: check with seller
This state requires UL 3700 (or complete-system certification). The certificate we have seen covers only one part, such as the inverter, so ask the seller whether the complete kit is certified.
State rules not yet verified
We have not yet confirmed this state’s rules on an official source.
