Is this compatible with my inverter?
Compatibility depends on your inverter and system configuration. Contact our team to confirm compatibility before purchasing.
Is professional installation required?
Yes - rapid shutdown devices must be installed by a licensed solar professional to ensure NEC compliance. Solwel offers installation at our Houston and Dallas locations.
