Microgrid & Distributed Energy Systems

September 24, 2025

Modern microgrids integrate renewable energy, storage, and intelligent control systems to deliver efficient and resilient power. Kripal Electric, with over 30 years of experience in electrical equipment manufacturing, provides a complete range of low-voltage components that ensure safety, stability, and interoperability in microgrid and distributed energy systems.

The company’s portfolio of circuit breakers, isolators, and EV charging products supports commercial, industrial, and rural applications, meeting the highest international standards such as IEC, UL, and GB.

Industry Challenges

The microgrid and distributed energy sector face several key challenges. One major issue is system reliability in hybrid networks that combine multiple generation sources, such as solar, wind, and diesel backup. Coordinating protection and switching across different voltages and current types can be complex, especially when renewable sources introduce fluctuating loads.

Another challenge is safety and compliance—many systems operate in harsh outdoor environments and must meet international standards to prevent faults and ensure personnel safety.

Finally, scalability and integration are critical concerns. Microgrids must evolve with energy demand, requiring modular components that can expand without major redesign. Kripal’s standardised and certified product ecosystem directly addresses these challenges, enabling seamless integration, high durability, and global code compliance.

Circuit Protection and Control

Reliable circuit protection is essential for safe microgrid operation. Kripal’s Miniature Circuit Breakers (MCBs) and Molded Case Circuit Breakers (MCCBs) provide precise overcurrent and short-circuit protection.

The UKB7 MCB series meets IEC 60898-1 for residential and commercial circuits, while MCCBs conform to IEC 60947-2, suitable for industrial loads. Kripal’s Automatic Transfer Switches (ATS) facilitate seamless transitions between utility and backup sources, ensuring uninterrupted power during grid outages.

Kripal’s Residual Current Devices (RCDs) protect against electrical shock and ground faults. Designed to IEC 61008/61009, they are ideal for homes, EV chargers, and business circuits. Combined with modular, DIN-rail designs, Kripal’s protection products simplify installation in microgrid control panels.

Isolation and Switchgear

Safe isolation is vital during maintenance or fault conditions. Kripal’s AC and DC isolator switches are designed to handle both conventional and renewable energy circuits. The UKPD32 Photovoltaic DC Isolator offers fast arc suppression (<3ms) and complies with IEC 60947-3, providing reliable disconnection for PV arrays and battery systems.

For AC networks, the UKP Load Break Isolator serves as a durable main switch, tested to IEC/EN 60947-3 and certified by VDE, SEMKO, and CE. Many models offer IP65/IP66 protection for outdoor use, ensuring longevity in harsh conditions.

Renewable Energy Integration

Kripal’s New Energy Series components are engineered for seamless integration of solar PV and wind systems. The company’s DC MCBs and DC MCCBs are rated up to 1500V DC, designed to protect high-voltage PV strings and storage links. PV surge protectors and gPV fuses provide additional protection against lightning and reverse currents, complying with IEC 61643 and IEC 60269-6 standards. Kripal’s combiner boxes and MC4-compatible connectors ensure secure, low-loss connections across renewable installations. Each element is optimized for efficient energy transfer, minimal maintenance, and safe isolation.

Energy Storage Integration

Battery energy storage systems (BESS) require precise protection on both DC and AC sides. Kripal’s DC disconnect switches and MCCBs enable safe maintenance and isolation of lithium-ion and lead-acid systems. Rated to IEC 60947-3, these switches handle voltages up to 1000V DC. On the AC interface, Kripal’s breakers and ATS units manage bidirectional inverter connections and load transfers in compliance with IEC 60947-6-1. Additional relays, surge protectors, and monitoring devices from Kripal’s Industrial Control Series support power quality management, ensuring compliance with standards such as IEEE 1547.

EV Charging Infrastructure

Electric vehicle charging is increasingly integrated into microgrid environments. Kripal’s EV solutions include dedicated MCBs/MCCBs, Type B RCDs, and IP66-rated switch-socket combinations for safe, outdoor operation. The 56CV series provides an all-in-one isolator and industrial socket solution compliant with IEC 60309, ideal for residential, fleet, and commercial EV systems.

These products meet IEC 61851 requirements, ensuring protection against AC and DC leakage currents, while contactors and metering devices enable integration with energy management systems for load control and smart charging.

Compliance and Quality Assurance

Kripal products meet global electrical standards, including IEC, UL, and GB. The company holds ISO 9001 certification, with products bearing CE, VDE, SEMKO, and CB marks. Equipment enclosures achieve IP65/IP67 ratings for environmental protection and are made from UL94-V0 flame-retardant materials. This ensures compliance across markets and enhances safety, durability, and performance in demanding environments.
