MidNite Solar 250 Amp w/Bus Bar MNDC250PLUS Breaker DC Disconnect

The MidNite Solar MNDC250PLUS is an advanced version of the popular MNDC series, specifically designed to provide comprehensive DC disconnection and circuit protection for a wide array of renewable energy installations. This "Plus" model offers expanded capacity for additional breakers, making it ideal for more complex and robust solar, wind, and hydro systems.

Key Benefits

Expanded Breaker Capacity: Features an additional DIN rail, allowing for up to ten DIN rail mount breakers, significantly increasing circuit management flexibility.

Versatile Mounting Options: Includes two DIN rail cover plates and two panel mount plates, enabling the installation of 3/4" 125VDC breakers ranging from 60 to 100 amps.

Comprehensive Protection: Comes with a pre-installed 250 amp inverter breaker for critical overcurrent protection.

Robust and Rust-Resistant: Constructed with a white powder-coated aluminum chassis, ensuring durability and preventing rust in humid or saltwater environments.

Easy System Access: A hinged door provides convenient access to all internal electrical circuits for maintenance and inspection.

Integrated Grounding: Includes a 14-pole ground bus bar and a 5/16" diameter stud for a battery negative tie point, ensuring comprehensive system grounding.

Current Monitoring Ready: Features six dedicated mounting spots for a 500 amp, 50mV shunt, allowing for precise current monitoring (shunt sold separately).

Optimized Cable Management: Equipped with various knockouts for inverter and battery cables, charge controller mounting, and DC/PV input/output.

Certified Safety: ETL listed for use in both the US and Canada, ensuring compliance with safety standards.

Made in the USA: Manufactured in the United States, reflecting quality and reliability.

Special Technology

Modular Breaker Integration: The added DIN rail and included panel mount plates allow for a highly customizable breaker configuration, supporting a wide range of DC loads, charge controller disconnects, and battery status monitor feeds. This enables the integration of specific components like the MNDC-GFP80 along with additional panel mount or DIN rail breakers.

Optimized Wiring: Designed with considerations for wire bending room, recommending super flexible battery cables (like Cobra Cable X-Flex) for optimal installation.

Integrated Monitoring Capability: While the shunt is sold separately, the pre-configured mounting spots facilitate seamless integration with monitoring solutions like the Whiz Bang Jr. current sense module for accurate amperage readings to compatible charge controllers.

Warranty

The  MNDC250PLUS Breaker DC Disconnect comes with a 5-year limited warranty, covering manufacturer defects in materials and workmanship. Warranty support is valid in the U.S. and Canada. 

Best Use

Larger Renewable Energy Systems: Perfect for residential and commercial solar, wind, and hydro installations that require extensive DC circuit protection and management.

Complex Wiring Setups: Suited for systems needing more than standard DC disconnects, providing additional space for breakers and integrated components.

Off-Grid and RV Applications: Offers robust and compact power management for off-grid homes and RVs, ensuring efficient solar energy utilization.

Battery and Inverter Protection: Centralizes the main DC disconnect and provides overcurrent protection for single inverters, as well as organization for critical battery and inverter connections.

Systems Requiring Detailed Monitoring: Supports the integration of current shunts for precise battery status monitoring.
