Product Description
Other components for the photovoltaic mounting system are provided as a complete set according to the project BOM: including fasteners—304/316 stainless steel bolts, nuts, flat washers, spring washers, and suspension bolts, A2-70 / A4-70 performance grade; structural connectors—rail couplers (extensions), transition plates, angle brackets, and groove nuts, used for rail extensions and node reinforcement; Grounding components—grounding clamps, grounding terminals, and equipotential bonding strips, which work with the mounting system to provide lightning protection grounding and equipotential bonding; front and rear legs—adjustable front/rear legs and base plates, which allow the design tilt angle to be set via leg height differences to accommodate flat-roof and ground-mounted installations; guardrails, walkways, and other products. We support both complete BOM supply and individual item orders.

FAQ
Q1: What exactly is in this kit?
A1: Four families: fasteners, structural connectors, grounding parts and front/rear legs. Supplied as a full BOM, or ordered by family or single item.
Q2: Does 'connector' here mean MC4 DC connectors?
A2: No. Connectors here are structural: rail splices, transition plates, corner brackets and channel nuts. MC4 and other electrical connectors are outside this category.
Q3: How are grounding parts specified?
A3: Quantity and type follow the project earthing design; we advise on bonding clamps, grounding lugs and bonding straps. Earth resistance is confirmed by on-site measurement.
Q4: How is leg length determined?
A4: From the design tilt and module layout as a height difference, commonly 300-1500 mm. Send tilt, span and mounting surface elevation and we configure it.
Q5: How do material and finish match up?
A5: HDG ≥85 μm to ISO 1461 for carbon steel, anodized ≥10 μm for aluminum, passivated stainless; 316 or stainless recommended for coastal chloride exposure.
