New Energy & DC Protection Products

DVolt Electric is a specialist global supplier of DC protection and distribution products for renewable energy systems, supporting solar PV and clean energy projects across major international markets including the USA, UK, Australia, Europe, the Middle East, and Asia-Pacific.

Modern solar and renewable energy installations rely on highly reliable DC electrical components to ensure operational safety, system uptime, and long-term energy output. At DVolt Electric, we focus on supplying certified, project-ready DC protection solutions designed for residential, commercial, industrial, and utility-scale renewable energy applications worldwide.

The Importance of DC Protection in Renewable Energy Systems

Solar PV and other clean energy systems operate primarily on the DC side between PV modules and inverters. Effective DC protection and distribution is critical to:

  • Prevent overloads, short circuits, and electrical faults
  • Protect inverters, PV modules, and balance-of-system components
  • Minimise downtime and maintenance risks
  • Ensure personnel and asset safety
  • Maintain long-term system efficiency and compliance

Our new energy product range focuses on DC-side protection, isolation, surge protection, and distribution, enabling renewable energy systems to operate safely and efficiently even in demanding environmental conditions.

Our Range of DC Protection & Distribution Products

We maintain a comprehensive inventory of solar DC electrical components required for efficient and compliant renewable energy installations.

DC Miniature Circuit Breakers (DC MCB)

DC MCBs provide essential protection for individual solar strings against overloads and short circuits. Our DC MCB range is suitable for:

  • Residential solar PV systems
  • Commercial rooftop installations
  • Large-scale and utility solar projects

They help preserve circuit integrity and improve overall system safety.

DC Moulded Case Circuit Breakers (DC MCCB)

For higher-capacity PV strings and demanding renewable installations, DC MCCBs are critical. These breakers are designed to safely interrupt severe DC loads and are widely used in:

  • Utility-scale solar farms
  • Industrial solar installations
  • High-voltage DC distribution environments

DC Isolator Switches

DC isolator switches are mandatory safety devices for maintenance and emergency shutdowns. Our DC isolators ensure safe disconnection of live DC circuits and are commonly installed near inverters, combiner boxes, and array junction points.

DC Surge Protection Devices (DC SPD)

Solar PV systems are often exposed to lightning strikes and transient voltage surges. Our DC SPDs protect inverters and PV modules from surge-related damage, making them essential for outdoor and utility-scale installations.

DC Fuse Holders & DC Fuses

We supply fast-acting DC fuses and fuse holders that provide precise and reliable string-level protection. These components are critical for maintaining system stability and preventing cascading electrical failures.

DC Combiner Boxes & Distribution Equipment

DC combiner boxes play a central role in solar power distribution. Our pre-engineered DC combiner boxes integrate:

  • DC fuses
  • DC MCBs or MCCBs
  • DC SPDs
  • DC isolator switches

They consolidate multiple PV strings into a single output, enabling efficient and safe DC power distribution in solar installations of all sizes.
