Roof-Mount & Ground-Mount Installation

This system can be used for either roof-mounted or ground-mounted solar installations, depending on the property and system design.

For a ground-mounted installation, module-level rapid shutdown devices may not be required depending on the applicable electrical code and local AHJ.

For a roof-mounted installation, rapid shutdown devices may be required and should be added separately based on the installation design and local code requirements.

Rapid shutdown devices are not included in the standard package.

Important Installation Note

Mounting/racking is not included. Final racking, rapid shutdown, AC and battery protection, grounding, utility interconnection, permitting, backup-load configuration, and site-specific wiring should be confirmed by a qualified solar installer and the local AHJ.

The ROCKSOLAR 20kW Hybrid Solar System combines 24.57kW of solar generation, 20kW of hybrid inverter capacity, and up to 57.36kWh of battery storage into a powerful solution for large residential, farm, and light commercial energy needs.
