Powering the World with Reliable Solar Infrastructure

Solar power has become the cornerstone of the clean energy revolution. As installations grow from residential rooftops to utility-scale farms, the demand for safe, efficient, and durable electrical components continues to rise.

Kripal Electric provides complete, certified low-voltage solutions that form the backbone of modern Solar PV Systems — enabling seamless energy conversion, optimized performance, and long-term safety in every environment.

The Challenges of Solar Power

High-Voltage DC Safety

Solar panels generate continuous DC voltage — often exceeding 1000V — where traditional AC protection is not sufficient. Reliable DC breakers and isolators are essential to prevent arcing and electrical hazards.

Variable Generation and Grid Balance

Changes in sunlight and temperature cause power fluctuations that can impact inverters, storage systems, and grid stability if protection and coordination are not precise.

Environmental Durability

Solar components face intense UV radiation, moisture, dust, and heat. Electrical parts must be engineered to resist corrosion and maintain insulation integrity over decades of exposure.

Efficient Maintenance and Scalability

PV systems demand modular, easy-to-service components that simplify installation and support future expansion without disrupting operations.

Kripal’s Comprehensive Solar Solution

Reliable DC Protection

Kripal’s DC-rated Circuit Breakers (MCBs/MCCBs) are specifically designed for solar applications, offering up to 1500V DC protection for PV strings, combiner boxes, and battery interfaces. Built to IEC 60947-2, these breakers ensure fast fault isolation and long-term electrical stability.

The UKPD32 DC Isolator delivers safe manual disconnection for maintenance, featuring <3ms arc suppression and IP66-rated enclosures suitable for rooftop and field installations.

Surge and Overcurrent Defense

Kripal’s gPV fuses and Type 2 Surge Protective Devices (SPDs) safeguard inverters and controllers from lightning strikes and transient surges, conforming to IEC 60269-6 and IEC 61643 standards. These ensure uninterrupted power delivery even in high-risk climates.

AC Integration and Distribution

On the inverter’s output side, Kripal’s AC circuit breakers, RCDs, and Automatic Transfer Switches ensure smooth connection to the grid or microgrid. Residual Current Devices (RCDs), compliant with IEC 61008/61009, offer essential personnel protection against leakage currents and insulation faults.

Smart and Modular Combiner Systems

Kripal’s preconfigured combiner boxes integrate breakers, isolators, and SPDs in a single enclosure. Combined with MC4-compatible connectors and high-conductivity busbars, they simplify field wiring, reduce installation time, and guarantee consistent build quality across large-scale solar arrays.

Designed for Harsh Environments

Every Kripal solar component is built for endurance and safety:

• Ingress Protection: IP65–IP67 sealing for water and dust resistance
• Material Integrity: UV-resistant and flame-retardant (UL94-V0) enclosures
• Thermal Range: Reliable performance from –40°C to +85°C
• Longevity: Mechanical endurance exceeding 10,000 operating cycles

From arid deserts to coastal regions, Kripal’s PV components deliver consistent performance under the toughest environmental conditions.
