I was building my summer house from scratch and this is what I used. It might seem frightening to look at, but an all-in system like this actually saves you a lot of time. Midnite devices I know well and I trust them, Shneider inverters work without any accidents, so the product is quality.
thank you for delivery, it arrived on time
Been using these for years. One of the best units out there. Outback used to be my favorite, but not any more. If you want the best wind controller, I recommend this model.
I purchased panels, batteries, an inverter and this controller here two months ago. The staff was very helpful and professional, their calculator is very convenient for sizing the system. The shipping took a little longer than expected due to some holidays, but it’s all good. nothing was damaged, nothing was missing. Good job!
I like how the chassis of the Midnight Classic are made. It is a top-notch charge controller that will help you prolong the life of your batteries if you follow the directions. Thanks for the recommendation, guys!
Following an outage last winter I decided to build a back up power system. I bought four used solar panels and this Midnite Solar controller. Installing the Classic is very easy once all the other elements are in place. It has an RJ45 connector for remote monitoring from any device on the network.
Extremely pleased with the charger. At first I coupled it with a 12v inverter, now I am using a 48v. Works like a charm. I had been without electricity for three week due to a hurricane, but thanks to my small solar system I did well
The best of the best! Has network capabilities... This CC is a piece of technology that creates real value to your off-grid applications. Has been my choice for more than ten years.
I have a 4800w system and they handle it all splendidly, and I have one more unit for the wind system I am going to build. I hope my wind system works as well as all midnite products I have used till this moment.
My friend has solar as well, but he had no charge controller. so his battery was constantly overcharged and eventually it stopped charging at all. that’s when I saw that getting a regulator really makes sense if you want to save your battery. Plus it’s very convenient cause you see what’s going on with your system
I didn’t know that charge controllers were a thing, but read a couple articles on your website and they were quite helpful. My last two batteries did in fact die too quickly and for a good reason. Hope that now with a regulator the new one will last longer.
The regulator is fine. It’s well made, at least it doesn’t look like it’s going to break in the next second. the monitor is good, you can adjust the charging process and whatnot. It’s pretty efficient from what i’ve seen. solid product
Purchased this bad boy along with Canadian Solar panels and outback inverter. thank you for all the help and advice! The package arrived, everything works like it should.
At first I wasn't sure if I even needed a charge controller, but after a bit of research I understood its purpose. It’s not that expensive anyway and the system is much safer this way. Thanks for the service!

About product
The Midnite Solar 4500 Watt Pure Sine Inverter in the RE (Renewable Energy) Version is a compact yet capable inverter/charger engineered for efficient off-grid and battery-backup solar applications. Delivering 4,500 watts of clean, pure sine wave AC power at 120VAC from a 48VDC battery bank, this unit produces utility-grade output suitable for sensitive electronics, appliances, and motor-driven equipment alike. Its integrated 60-amp battery charger provides reliable and efficient recharging from a utility grid or generator connection, keeping battery reserves ready during periods of limited solar input or elevated energy consumption.
Designed specifically for renewable energy environments, the RE Version offers enhanced compatibility with solar and wind charge controllers commonly deployed in off-grid system architectures. Built on Midnite Solar's legacy of American-engineered quality and field-proven performance, this inverter strikes an ideal balance between power output and system footprint — making it a smart choice for smaller off-grid homes, cabins, and backup power installations where space and budget efficiency matter without compromising on reliability. Its configurable charge settings and straightforward interface simplify both initial commissioning and day-to-day system management.
Key Features
- 4,500W pure sine wave output delivers clean, reliable 120VAC power
- RE Version engineered for seamless renewable energy system integration
- Integrated 60A charger efficiently replenishes 48V battery banks from AC sources
- 48VDC input compatible with lithium, AGM, flooded, and gel battery banks
- Compact footprint suits space-constrained off-grid and backup installations
- Configurable charge profiles support multiple battery chemistries and capacities
- Robust construction delivers dependable performance in demanding environments
Applications
The Midnite Solar 4500W RE Inverter is an excellent fit for small-to-mid off-grid cabins, cottages, tiny homes, and remote facilities with moderate 120VAC power requirements. Its 60A integrated charger makes it equally well suited for grid-tied battery backup systems where reliable and timely recharging is essential. Installers and owner-builders will value its native compatibility with Midnite Solar's family of charge controllers and system components, allowing it to serve as a dependable and scalable core in a thoughtfully designed renewable energy system. For properties that don't require split-phase 240VAC loads, this inverter delivers an efficient, right-sized solution without the cost or complexity of higher-output units.
