Direct Manufacturer. 100% Rigorously Tested

Reliable Solar DC Electrical Components for Commercial PV Systems

Commercial solar and Battery Energy Storage Systems (BESS) operate on high-voltage continuous direct current. Standard AC protection simply cannot safely break a DC circuit. To prevent electrical arcs and system downtime, you need purpose-built protection. KRIPAL manufactures a complete range of solar DC electrical components rated for 1000V to 1500V DC. From rapid-response isolator switches to heavy-duty PV combiner boxes, our components feature advanced magnetic arc-extinguishing technology and flame-retardant housings. We build our products to keep your solar infrastructure safe and operational, even in extreme outdoor conditions ranging from -40°C to +85°C.

Tailored OEM & ODM Solutions for Global EPC Contractors

We work directly with distributors, system integrators, and EPC contractors to deliver solutions that fit specific project demands. As a direct manufacturer, we offer:

Custom Enclosures: Tailored PV combiner boxes with specific waterproof ratings (IP65–IP67) and UV-resistant materials for harsh outdoor environments.
Flexible Configuration: Integration of specific string inputs, DC MCBs, and SPDs to match your exact energy storage or solar array design.
Direct Manufacturer Pricing: Cut out the middlemen and work directly with our engineering team for bulk orders and project pricing.
Certified Compliance: All customized DC protection units are backed by CE, CB, TUV, SEMKO, LVD certifications, ensuring your projects pass local grid-connection inspections without delays.

Frequently Asked Questions

Explore FAQ >

Why is DC-specific protection critical for Solar PV systems?

DC circuits lack a zero-crossing point, making electrical arcs significantly harder to extinguish than in AC systems. Using standard AC breakers in PV applications is a direct fire hazard. Our DC components utilize specialized magnetic arc chutes (arc-blowout technology) to actively stretch and interrupt sustained arcs at up to 1500V DC.

Does KRIPAL provide customized solutions for EV charging infrastructure?

Yes. We manufacture OEM/ODM components for EVSE (Electric Vehicle Supply Equipment) networks. Our portfolio includes IEC 62196-2 compliant Type 2 connectors and heavy-duty high-voltage DC contactors engineered specifically for DC fast chargers and BESS setups.

Are your solar components compliant with international safety standards?

All components are type-tested and certified to relevant IEC/EN standards. Our current certifications include TUV, CE, CB, and SEMKO, ensuring immediate compliance for grid-tied and off-grid EPC projects globally.

What is the maximum voltage rating for your DC MCCBs?

Our UKM5DC series molded case circuit breakers (MCCB) are designed for high-capacity applications, supporting DC distribution and energy storage systems with ratings up to 1500V and 400A.

What are the environmental operating limits for KRIPAL outdoor components?

Enclosures and switch disconnectors are molded from UV-stabilized, flame-retardant materials. The standard operating temperature ranges from -40°C to +85°C, with ingress protection ratings from IP65 to IP67, depending on the specific component.

Do you support OEM/ODM customization for project-specific demands?

Yes. As the original manufacturer, we provide direct engineering support for EPCs and integrators. We can customize internal wiring schematics, component selection (fuses, MCBs, SPDs), enclosure IP ratings, and terminal blocks to match your exact project specifications.

How do your PV Combiner Boxes integrate into system designs?

By aggregating multiple PV strings into a single DC output, they minimize line losses and field wiring costs. Our enclosures come pre-wired with matched DC MCBs, Type 2 SPDs, and gPV fuses. We build to IP65/IP66 standards, ensuring streamlined field installation and targeted fault isolation.
