Busbar Solvian 48V 150A – bloque distribuidor de cobre estañado de 4 pernos para sistemas DC

On a 48V DC solar array or marine battery bank, every connection point must handle high current without voltage drop or heat buildup. The Busbar Solvian 48V 150A provides a centralized, low-resistance junction for positive and negative distribution, featuring four M8 studs on a tinned copper bar rated for 150A continuous. Install it in an enclosure, connect your battery, inverter, and load circuits, and you get a clean, safe, and serviceable power distribution solution.

Key specifications

• Nominal system voltage: 48V DC (max 60V DC)
• Continuous current rating: 150A
• Number of terminal studs: 4 (M8 thread)
• Busbar material: tinned copper for corrosion resistance
• Base material: glass fiber reinforced nylon (flame retardant)
• Cover: clear polycarbonate for visual inspection and touch safety
• Mounting: surface mount with 5 mm holes
• Recommended terminal torque: 10 Nm (7.4 ft-lb)
• Operating temperature: -40°C to +85°C
• Dielectric strength: 1500V AC for 1 minute
• Insulation resistance: >100 MΩ

Why choose it

This busbar eliminates messy wiring and multiple ring terminals stacked on a single post. The tinned copper conductor ensures excellent conductivity and resistance to oxidation, while the reinforced nylon base provides high mechanical strength and electrical isolation. The clear cover allows quick visual checks without removing protection, reducing the risk of accidental shorts. With a 150A rating, it easily handles the demands of most 48V systems, including inverters up to 7.2kW.

Ideal use cases

• DC power distribution in off-grid solar installations
• Marine and RV electrical panels for battery and load connections
• Automotive auxiliary power systems
• Industrial 48V DC equipment and control cabinets
• Consolidating multiple negative returns in a centralized point

Good to know

Always torque connections to the recommended 10 Nm to ensure low contact resistance and prevent loosening from vibration. The busbar is designed for surface mounting; use appropriate screws through the 5 mm holes. For higher current applications, consider paralleling multiple busbars or using a larger conductor. The operating temperature range of -40°C to +85°C makes it suitable for harsh environments, but avoid direct exposure to water or corrosive chemicals unless additional protection is provided.
