Company Overview
MidNite Solar, Inc. is headquartered in Arlington, Washington (17722-67th Ave NE, Arlington, WA 98223). The company was founded by a team of renewable energy industry veterans with deep experience in off-grid system design and manufacturing. MidNite Solar's origins are closely tied to the development of the E-Panel—a pre-wired, space-saving enclosure that revolutionized how off-grid inverter systems are assembled by consolidating AC and DC disconnects, breakers, and busbars into a single compact chassis.
MidNite Solar's market position is that of an off-grid specialist with a focus on North American code compliance (NEC, UL), extreme reliability, and Made in USA manufacturing. The company's products are designed to work together as an integrated system—Classic charge controllers pair with E-Panels, which pair with MidNite breakers and surge protectors—but are also compatible with major third-party inverters including OutBack, Magnum, Schneider, and SMA.

Installation Notes
System Sizing
Classic charge controller sizing follows these maximums:
- Classic 150 (12V): 96A x 12V = 1,152W max array
- Classic 150 (48V): 86A x 48V = 4,128W max array
- Classic 200 (48V): 78A x 48V = 3,744W max array
- Classic 250 (48V): 55A x 48V = 2,640W max array
Wire Sizing
- Classic DC terminal accepts #14 to #4 AWG wire (use THHN; #4 AWG welding cable will not easily fit).
- Typical output wire: #6 AWG for Classic 250, #4 AWG for Classic 200/150.
- AUX 1 and AUX 2 terminals accept up to #18 AWG.
- NEC requires 1.56 times PV short-circuit current for PV input wire sizing.
Minimum Input Voltage
The Classic requires a minimum input voltage to start: multiply the highest expected battery voltage by 1.33. If PV input voltage is lower than this value, the Classic will not come out of resting mode. For a 12V system, the Classic 150 operates optimally with 70-90V input.
Environmental
- Operating temperature: -40°C to 40°C (current de-rates above 40°C: 80A for Classic 150, 66A for Classic 200, 52A for Classic 250).
- Environmental rating: Type 1 (Indoor).
- Dimensions: 14.87" x 5.95" x 4.00" (378mm x 151mm x 102mm).
- Weight: 12 lbs (shipping: 17 lbs).
E-Panel Installation
E-Panels are designed for wall mounting with the inverter hinged on the enclosure door, keeping the system footprint compact. All E-Panels include mounting brackets for one-person installation. The inverter, remote control, and charge controller mounting hardware is included. Knockouts are provided for battery cables and AC conduit. DIN-rail space accommodates additional AC/DC breakers for PV, wind, hydro, or AC distribution circuits.
Frequently Asked Questions
1. What is HyperVOC and why is it important?
HyperVOC is MidNite Solar's exclusive feature that extends the maximum input voltage limit based on the battery bank voltage. For example, the Classic 150 in a 24V system offers HyperVOC protection up to 150V + 24V = 174V. This protects the controller from over-voltage conditions in cold climates where panel Voc can spike above rated limits, without requiring the controller to shut down and lose production.
2. Can the Classic charge controller handle wind and hydro sources?
Yes. The Classic is the only major MPPT charge controller with dedicated wind and hydro MPPT tracking modes. It has several different tracking algorithms that can be fine-tuned for each input source. This makes it ideal for hybrid off-grid systems combining solar with micro-hydro or wind turbines.
3. What is the E-Panel and how does it save installation time?
The E-Panel is a pre-wired enclosure that consolidates all AC and DC overcurrent protection, disconnects, busbars, and shunt into a single compact chassis. By pre-wiring the AC bypass switch, generator/utility input disconnects, and inverter cables, the E-Panel eliminates hundreds of dollars in separate components and hours of installation labor. The inverter mounts on a hinged door, and the entire system can be installed by one person using the included mounting brackets.
4. What is the difference between the Classic and the Classic SL?
The Classic (full version) includes a graphical display, voice annunciations, and advanced menu navigation. The Classic SL (Solar-Only) is a reduced-feature version with dip-switch programming, LED indicators for charge state, and no graphical display. The SL is solar-only (no wind/hydro modes) but shares the same power stage, HyperVOC, and UL 1741 certification. The SL costs approximately $95-$120 less than the full Classic.
5. How does the MidNite extended warranty program work?
Six months before the Classic's 5-year warranty expires, customers can ship the controller back to MidNite Solar with a check for $147 plus shipping costs. MidNite will replace any wearable parts and perform a general tune-up. This extends the warranty by 2 additional years (7 years total). This program is available for all Classic MPPT charge controllers.
