    A good, if basic Charge controller for a 12/24v system.
    This solar charge controller has been solid in my setup. Installation was straightforward, and the automatic 12V/24V detection made things easy right from the start.

    Ease of use is good overall — the external LCD display gives clear, accurate information on charging status and battery voltage, which helps with monitoring. Battery management feels reliable, and it supports multiple types including LiFePO4, which adds nice customizability for different systems.

    Functionality has been consistent, and it seems to handle charging efficiently. For the price, it’s a practical and accurate unit that does the job well.

    Strong Controller, Useful Display
    I added this controller to an off-grid Electric Fence setup on our North Florida property, where reliable solar equipment matters more than fancy packaging. The automatic 12/24-volt detection removed one setup step, and the external LCD makes it easy to check panel input, battery condition, and load information without standing beside the controller like I am waiting for it to confess something.

    Support for several battery types, including LiFePO4, gives me flexibility as the battery bank evolves. The included display cable is long enough to put the readout somewhere convenient, and the readings have been clear and consistent during use. The controller has handled the system load without fuss.

    My one minor complaint is that the manual is fairly dense, so the initial setup deserves a careful read. Once configured, the display and controls are straightforward. Overall, this is a capable controller with useful remote monitoring and plenty of battery compatibility.

    Golden Review Award: 1 From Our UsersSolid controller with a useful remote display
    This 100A solar charge controller feels like a capable option for a 12V or 24V solar setup. The external LCD is the standout feature because it lets you mount the controller where it has airflow while still keeping the charging and battery information easy to read. I also like the broad battery support, including lead acid, AGM, gel, flooded, and LiFePO4, which gives some flexibility if the battery setup changes later.

    Setup is fairly straightforward if you already understand solar wiring, but this is not something I would install casually without checking panel voltage, battery type, wire size, and system limits first. The manual takes some attention, and good wiring matters. Once configured, the MPPT charging, automatic voltage detection, aluminum housing, and built-in protection features make it a practical controller for RV, off-grid, backup, or small solar projects.

    Excellent solar charge controller with handy small panel that can be remotely located.
    This is a very high quality solar charge controller that takes the place of much more expensive name brand controllers but does just as good a job in my opinion. It works fantastic at protecting battery life by controlling input to our AGM gel batteries with the right voltage and a varying amperage according to battery condition temperature and other functions such as state of charge that are built in. This one has the remote positionable external LCD that lets me access the controls from some distance away which is Handy to have. Overall it’s very easy to use and very easy to program. I customize it by telling it the type of batteries I have and the number and how they are arranged and this charge controller takes over and acts as a master battery management system for charging. The unit is very durable physically and appears to be well made. I think it’s a great deal and it’s been working great for me.

    Golden Review Award: 1 From Our UsersOutstanding power tracking and convenient dual display
    Setting up a dependable solar array requires components that can handle heavy power loads smoothly. This 100 amp unit is an absolute workhorse for managing off grid solar configurations or large backup battery banks. The automatic voltage detection effortlessly configures itself for 12 volt or 24 volt systems which saves a lot of manual programming hassle during the initial installation. Having a solid aluminum housing is excellent for heat dissipation and keeps the internal electronics running cool under continuous load.

    The maximum power point tracking efficiency is outstanding and squeezes every single bit of available energy out of the solar panels even on overcast days. Having the secondary external LCD screen with the included long extension cable is an incredible feature because it allows you to mount the bulky main controller hidden away in a ventilated utility box while keeping the live data readout right where it is easy to monitor. It seamlessly handles lithium iron phosphate batteries alongside traditional sealed or AGM banks. The built in safety protections against overheating, overloading, and overcharging give complete peace of mind for unmonitored operation.

    En funcion de carga va muy bien por ahora
    Primer dia de uso . Esto es lo que descubri por ahora. Cumple con lo que dice,. Carga eficientemente y se puede modificar los parametro de carga, y no sobre carga las baterias lifepo4. Se adabta facilmente es decir automaticamente y ni tienes que estar elijiendo tipos de baterias en el menu.. etc.

    Pequeos detalles biene con un cable para sensor de temperatura para la bateria pero no te indica como se conecta si directo a la bateria o se tiene que comprar algo mas? Revice la guia no encontre nada,.

    Una mas despues de que entra la noche el ventilador de enfriamiento se quedo ensendido 2 horas mas. Para mi opinion es un gasto de energia de la bateria inecesario. .. les seguire actualizando.

    Nota al comprar este producto asegura de leer bien que incluye en la caja. Yo no revice y me salio el basico que no trae la pantalla externa que se ve en las imagenes .
