MidNite Solar Classic 150 MPPT Charge Controller, 96A, 12-72V, 150VDC

The MidNite Solar Classic 150 MPPT Charge Controller is a professional-grade MPPT solar charge controller rated for 150VDC PV input and up to 96A output, supporting battery banks from 12 to 72 volts. Designed and assembled in the USA, it combines arc fault detection, DC ground fault protection, and the exclusive HyperVOC technology in one ETL-listed enclosure — covering solar, wind, and hydro charging from a single unit.

Key specifications

• Max PV input voltage — 150VDC; HyperVOC extends effective VOC to 198VDC at a 48V battery
• Max output current — 96A at 12V; 94A at 24V; 86A at 48V; 65A at 72V battery
• Battery voltage — 12–72V nominal; regulation set points 10–100VDC
• Built-in protection — DC-GFP and Arc Fault Detection (0.25-second detect and trip); resettable, no fuse to blow
• Certifications & warranty — ETL listed to UL1741 & CSA (US & Canada), CE Certified, FCC Class B; 5-year warranty

High efficiency across wide battery voltages

Most MPPT controllers compromise between PV string size and battery bank voltage. The Classic 150 achieves 98% power conversion efficiency across its full 12–72V battery range, minimizing harvest losses whether the bank runs at 24V or 48V. Its built-in DC-GFP and Arc Fault Detector eliminate the need for separate protection devices, reducing installation complexity and parts count on every job.

Key Applications

• Off-grid residential — charges 24V, 48V, and 72V battery banks at up to 94A, 86A, and 65A respectively, accommodating large panel arrays without a separate combiner.
• Wind and hydro hybrid systems — dedicated MPPT modes for turbines and micro-hydro generators let a single controller optimize harvest from multiple renewable sources simultaneously.
• Cold-climate installations — HyperVOC safely accommodates the elevated open-circuit voltages that occur on cold mornings without tripping or requiring a derated array.
• Positive-ground systems — fully supported with two-pole input and output breakers for RV, marine, and specialty wiring configurations.

HyperVOC, multi-input MPPT, and monitoring

• HyperVOC — MidNite Solar's proprietary input extension adds the battery voltage to the 150VDC ceiling, allowing effective PV open-circuit voltages up to 198VDC at a 48V battery — a real-world safety buffer for cold-morning voltage spikes on larger strings.
• Solar, wind, and hydro MPPT modes — selectable tracking algorithms optimize harvest for the power curve of each source type, improving yield compared to solar-only controllers applied to turbines or run-of-river hydro.
• 380-day data logging — 380 days of daily history plus 24 hours of 5-minute interval data stored on-board, accessible via the built-in graphical display or remotely without additional hardware.
• Battery temperature compensation — automatic when the included MidNite Battery Temperature Sensor (MNBTS) is connected, with adjustable mV per degree C per 2V cell for accurate charge profiling across seasons.

Wiring, communications, and system integration

The Classic 150 communicates via Modbus over Ethernet and RS232. MidNite's free Local Application software provides full network-based viewing and control; MyMidNite.com enables cloud monitoring without a separate gateway. The optional MNGP graphical display can be relocated over a standard 4-conductor phone cable, no hub required. Terminals accept 75°C (167°F)-rated conductors. Conduit entries include single 1-inch (25.4mm) knockouts on both sides and two ¾-inch (19.05mm) knockouts on the back. The environmental rating is indoor Type 1 (IP30); adding the Classic Drip Shield upgrades protection to IP22 for damp locations. Two programmable auxiliary outputs handle external load disconnect and reconnect. Multiple Classic units can run in parallel via the Stacking/Follow-Me feature using standard phone cable — no hub needed.

Why choose the MidNite Solar Classic 150?

The MidNite Solar Classic 150 MPPT Charge Controller includes DC ground fault protection, arc fault detection, and HyperVOC as standard — capabilities most competing controllers require additional hardware to match. It ships ready to install with the MNBTS temperature sensor and a printed manual, backed by a 5-year warranty and ETL listing for both the US and Canada. For installers who need a high-current, multi-source controller that meets certification requirements without sacrificing monitoring depth or installation flexibility, the Classic 150 is designed and assembled in the USA to deliver exactly that.
