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.
