The MidNite Solar Classic 150-SL is a high-power, simplified solar-only MPPT charge controller designed for off-grid systems up to 150VDC input. With a streamlined menu for easy setup, it delivers up to 96 amps of charging current for 12V to 72V battery banks. Featuring built-in DC ground fault protection, exclusive HyperVOC for cold climates, and the ability to parallel with other Classic models, it is ideal for large off-grid residential, cabin, or remote industrial solar installations. Made in the USA.
Key Features & Benefits
High Output Current: Delivers 96A on 12V, 94A on 24V, and 86A on 48V battery banks – one of the most powerful 150V MPPT controllers available.
Wide Battery Voltage Support: Works with 12V, 24V, 36V, 48V, 60V, and 72V battery banks.
Battery Types: Flooded, AGM, Gel, Calcium SMF, Lithium (with BMS), Custom
150VDC Operating Voltage + HyperVOC: Exclusive HyperVOC extends VOC limits for cold climates up to 198V (non-operating safety zone). Ideal for cold weather solar arrays.
Built-In DC Ground Fault Protection (GFP): Integrated, resettable GFP meets NEC 2014/2017/2020 requirements – no external GFP device needed.
Simplified Solar-Only Operation: Streamlined menu structure – easy to set up and install. No wind/hydro programming, no Arc Fault, no Ethernet.
True Parallel Capability: Can be paralleled with other Classic SLs, Standard Classics, and Classic Lites for coordinated battery charging (Follow-Me).
High Efficiency (98%): Maximizes energy harvest from your solar array.
Built-In Data Logging: Stores 380 days of daily history and 24 hours of data at 5-minute intervals.
Dual Programmable Auxiliary Outputs: Two AUX outputs for load control, generator starting, low battery disconnect, or logic input from a lithium BMS.
Remote Display Capable: MMGP graphical display is included standard. A second display can be added or the display can be relocated.
Whiz Bang Jr. Compatible: Optional current monitoring module for precise amperage readings from a 50mV/500A shunt.
Terminals Rated for 75°C: Accepts #14 to #4 AWG copper wire.
5-Year Warranty: Backed by a 5-year standard warranty with an extended service program available.
Made in the USA: Designed and assembled in Arlington, Washington.
