Works well with bank of two 12.8v LiFepo4 100Ah
This MPPT is a great step up from a PWM charger. Works well with my 500W of solar. Can handle all battery chemistries like SLA, GEL, AGM, (LiFePO4). Clear instructions for install. I'm using it with my battery bank of two Wattcycle 12.8v LiFepo4 100Ah. Manages to keep them topped off while I'm intermittently running a a 4K BTU window unit, laptop, 12v cooler, and one power tool charger. Does well to recover my batteries from when I've run them completely flat from forgetfulness. This MPPT should survive years if properly installed and set up. Good unit to futureproof if you are planning to switching to 24V. I like that it has the flexibility of 12V or 24V, 500W on 12v, 1000w on 24v. I plan to expand my solar as well as battery bank eventually to 24V. I do wish it had bluetooth connectivit

Solar Charging Made Simple
This MPPT controller feels well-built, and the metal housing adds a reassuring, durable touch for RV or off-grid installs. The LCD is easy to read at a glance, showing the key stats you actually care about for monitoring and quick troubleshooting. Auto-detecting 12V/24V is convenient, and it settles into a steady charging routine without fuss. It’s a practical upgrade if you want a cleaner, more organized solar setup with clearer day-to-day visibility into what the system is doing.

Robust Build Quality Marred by a Simple Labeling Oversight
Being an electrical engineer and a licensed ham radio operator, I have spent a significant amount of time working with various solar power components. Living in a hurricane-prone area of Florida, reliable off-grid power isn't just a hobby; it is a necessity for emergency preparedness. Over the years, I have worked with a wide spectrum of solar panels, from small 10W units up to 300W panels, and this MPPT controller is one of the most impressively built pieces of hardware I have encountered. The die-cast aluminum housing and the substantial integrated heat sink on the back are excellent, providing the kind of thermal management you want when managing a 40A load. I primarily use this with LiFePo4 batteries, though it is versatile enough to handle most common chemistries. The backlit LCD is c

It works great and consistently
Just put this beauty into my off-grid system, and it does an awesome job!! Right now, I'm getting between 19-20 volts from solar panels to batteries and charging 39-40 amps when the sun is up. The batteries are being charged with a steady amount of energy, with no fluctuations at peak charge times, and everything stays steady once it gets locked onto the array. The output was very steady with no random drops in output. The enclosure feels great, and the terminals are solid.
