Universal black center clamp for PV modules

Universal black center clamp for PV modules

Universal black center clamp for PV modules from stock PVGroup.plThis is inventory left over from completed projects—brand new goods, sold while supplies last.

The most important features

• Type: universal middle (intermediate) clamp - connects two adjacent modules in a row at one mounting point
• Material: Aluminum alloy 6063 T6 (ALUPV) / Aluminum 6060 (equivalent to H24 in e-Altamira)
• Dimensions: ALUPV: length 50 mm, height 25 mm, thickness 3 mm, M8 hole. H24 equivalent: 36 x 24,3 mm, M8 hole (Ø8,5 mm)
• Frame thickness range: 24 mm working height allows for mounting modules with a frame thickness of 30–40 mm (applies to the H24 equivalent from e-Altamira)
• Grooving: teeth on both sides engage the panel frames and prevent them from shifting
• Black finish: corrosion-resistant black anodizing (black variant)
• Brand new product from stock, sale while supplies last

Application

Two adjacent PV modules are pressed against the profile at a single point—a repeatable element in each row. "Universal" means a single working height that supports a typical frame range; when selecting, the frame thickness range for a specific batch must be confirmed.

Technical Specifications

Application in a photovoltaic installation

The clamp transfers the entire weight of the module, along with the snow and wind load, to the profile, so selecting it to match the frame thickness is not a detail. A clamp that is too large will not press the module across the entire contact surface, while one that is too small will not fit the frame or will deform its edge.

You can check the frame thickness in your module's catalog datasheet—manufacturers provide it directly, and within a single series, it can vary for different power ratings. A typical row requires both types of clamps: end clamps close the row at the edge of the profile, and middle clamps connect adjacent modules.

The color is purely visual. Black terminals on modules with a black frame are less visible from ground level, which can be important for installations on buildings with aesthetic requirements.

Universal center clamp - what to pay attention to when choosing one

When purchasing this item, check three things: compatibility with existing equipment on site, site conditions, and the quantity needed for the entire project. Photovoltaic system components operate outdoors for several years, in full sunlight and with fluctuating temperatures, so the choice of material and workmanship is crucial to the durability of the entire installation.

If you are collecting material for a specific installation, it is more convenient to take everything from one delivery - the remaining items from the same group can be found in the category of fasteners and clamps , and all surplus stock in the category of Stock.

Where does this stuff come from?

We sell inventory left over from closed projects and deliveries. The merchandise is brand new and covered by the same returns and refunds policy as the rest of our offerings. The only difference is that quantities are limited and will not be restocked—once the stock is depleted, the item will be removed from the store.

Minimum order and price calculation method

We sell this item from 10 pieces. The price listed for each item is for a single item, so the minimum order value is 10 times that amount. This threshold is based on inventory accounting: for small items, the time required to deduct and pack several items costs more than the item itself. However, when ordering a full package, this cost is spread across all items, allowing the unit price to drop that low.

The quantity ordered increases incrementally in the cart, so you can't accidentally place an order below the threshold. Above the threshold, you can purchase any number of items until stocks last—which is limited to what's left in stock.

Delivery and pickup

Orders are shipped from our warehouse. Shipping costs depend on size and weight—small items are shipped as a parcel, while items longer than a standard parcel require pallet shipping, which is visible in the shopping cart after adding items. For orders with multiple items, shipping costs are calculated once for the entire shipment, so collecting the materials for a single order is cheaper than shipping several items separately.

You can also collect the goods in person at our warehouse in Bytomiu — pickup is free. For low-value items, this is often the most reasonable option, as shipping costs can be as high as the order itself. It's worth confirming availability before arrival, especially for last-minute items.

Frequently Asked Questions

How to choose the clamp size?

The size of the end clamp is selected according to the thickness of the module frame - check it in the catalog card of your panel and select the appropriate variant.

What is the difference between an end clamp and a middle clamp?

The end cap closes the row of modules at the edge of the profile, while the middle cap connects two adjacent modules. A typical row requires both types.

Can I collect the goods in person?

Yes, personal collection in Bytomiu is free—you select it in your cart. For small items, this is often the most reasonable option, as shipping costs can be as high as the value of the item itself.

How many pieces are available?

This is a surplus stock item – quantities are limited and displayed next to the product. Once stocks are depleted, the item will be removed from the offer.
