What should be included in a PV mounting system?

PV mounting systems and devices: Devices and systems used for mounting PV modules that are also used to provide grounding of the module frames should be identified for the purpose of grounding solar panels. Adjacent modules: Devices identified and listed for bonding the metal frames of PV modules can bond one panel to an adjacent one.

How big can a torque tube mount be?

Bolts can be tightened from below, so ladders are not needed, and installation is fast and safe. The module mount universal design can handle frames from 25 mm to 50 mm high. Brackets can be put on the torque tube at any spacing, accommodating modules up to 1.3 meters (51 inches) wide.

Can a PV panel be bonded to an adjacent racking?

Adjacent modules: Devices identified and listed for bonding the metal frames of PV modules can bond one panel to an adjacent one. To ensure NEC requirements are met, one should follow the racking manufacturer’s torque specifications to tighten down all connection points.

How do you mount an inverter to a bracket?

6 Hang the inverter on the bracket: Align the two indentations in the inverter enclosure with the two triangular mounting tabs of the bracket, and lower the inverter until it rests on the bracket evenly.Secure the inverter to the bracket using the two supplied 5mm screws.

What are the NEC 690 requirements for PV systems?

Additionally, a clear 3-ft pathway needs to be available for firefighter access to the roof. NEC 690 defines electrical safety requirements for PV systems. Equipment grounding required: Exposed non-current-carrying metal parts of PV module frames, electrical equipment and conductor enclosures must be grounded.

How are PV panels attached?

The PV panels are attached with a pull/end clamp combination providing a robust and secure connection to the bucket. Pre-installed bolts on the racking determine the tilt and inter-row spacing. We clamp on all 4 sides of the long rail frame on the long in landscape orientation.
