   Many features in a small package
   We have a large patio with over a hundred string lights and I wanted to use solar energy to power them. After purchasing a solar panel, a battery and an inverter, I still needed a controller to manage battery charging and load control. This product looked like the optimal choice based on power capacity, size and cost. After integrating it into my system I discovered that making all electrical connections was very easy and control setup simple and straightforward. One feature I was unaware of but happy to discover was the timer function that automatically switches on the load output when the solar panels no longer generate power and can remain on for a progammed amount of time. Our patio lights now turn on at dusk and remain on for 4 hours. A perfect solution for my application. Great product and highly recommend.

   Great product
   The instructions are very good. They emphasize the look of the connector when “open” and “closed” which is very important to make sure your wires connected properly. I connected the unit to a power supply with a 13.6 power source and then used a small 12V battery to test out the system. The readout of the controller said 3 amps charge current and the power supply also read 3amps. The battery started to charge. Then I connected it to a solar panel and it read 5.5 amps and the battery charged. The unit reads out your source voltage and current and the battery voltage and current, if you connect a load to the battery, which I did not use. Price was good and it worked as advertised. Highly recommend.

   Great solar charger
   I got this to charge my li po battery’s. Works like a charm. Enough for what I need. One of the great features of this charger is that you can change the type of battery to use it with. Renogy has worked well for me.

   Perfect
   This little 10 amp unit has worked for over a year perfectly. Yes I would buy another one! I am running 2 controllers 1 for movement and 1 for power.I use it to run a duel axis solar tracker system (ECO-Worthy) with 125W panel. I use a LiTime 50 amp lithium battery to power movement. This unit is able to keep the battery charged and to move my 2 linear actuators at 7amps each with solar dual axis controller for over a year now. My main system is a 60 amp Renogy system with 1600 watts of panels

   Simple, reliable PWM controller. Gets the job done.
   I built a small, off-grid solar system for my shed to power LED lights and a small ventilation fan that consisted of a 50W 12V-class panel (open circuit voltage around 20V), a 10 amp-hour LiFePo4 battery, and this charge controller. In that setup, it’s worked great. It’s a basic, workaday PWM charge controller that had worked great in my shed for several years until I decided to upgrade the system and added more panels and put in an MPPT controller.Pros:- Small size.- Reasonable price.- Terminals hold wires firmly and are easy to loosen and tighten. (Tip: crimp ferrules onto the ends of stranded wire rather and insert them into the terminals. Clamping stranded wire into the terminals is a bit harder, messier, and more prone to error.)- Backlit screen.- Easy to configure for flooded, AGM, and gel lead-acid batteries, as well as for LiFePo4 batteries.- Charging voltage is configurable for LiFePo4 batteries (in case you want to stop charging at, say, 14.4V rather than 14.6V).- USB ports are handy for charging phones or powering other devices.- It has options for turning the load on and off at and for various times. For example, the load can be turned on all the time, toggled with the push of a button, or when the sun sets (either until morning, or for various periods of time after sunset).- It supports — but does not include — a Renogy Bluetooth module that allows for remotely changing settings, seeing the current status, etc. from the Renogy app.- Manual is clearly written in English and explains all settings and options clearly.Cons:- This is a PWM controller which, while simpler, inherently limits its efficiency and requires a bit more planning relative to an MPPT controller. For example, connecting multiple 12V-class panels in series (or using one with a nominal open-circuit voltage greater than about 20V) provides no benefit. They need to be connected in parallel, and then one must make sure not to exceed the 10A current rating of the controller (it does not have any current limiting capability).- Turning on the load also enables the USB ports, which consume about 100mA of current when idle. With the load off, the current consumed by the controller itself is negligible. Still, it’d be nice to have the load on and disable the USB ports.- The on-device settings for having the load switched on or off at various times of day are unclear and require consulting the manual to know what the various codes mean.- The Bluetooth module is very basic and neither it nor the Wanderer 10 have any sort of data logging. You can see the current status and change settings, but no historical data is available. You apparently need some other Renogy device to accomplish that.- The Renogy app has many features, such as social features, promotions, etc. that distract from the core functionality of managing the controller.- Although the controller is reasonably priced, but the Bluetooth module is costly. Combined, their cost exceeds that of a reputable competitor’s MPPT controller with built-in Bluetooth, data logging, a better app, and better integration with other devices and remote monitoring.In short, it’s an inexpensive, simple PWM charge controller. If that’s what you need, it’ll do the job quietly and without complaint for years.However, if you want to use the Bluetooth module with this controller, you’re limited to live monitoring and changing of settings only. No data logging or historical data is available. For less money than the controller + Bluetooth module, you can get a comparable-power-limit MPPT controller from a major competitor that includes better monitoring, data logging, and higher efficiency.

   Está muy bien. Te muestra voltaje y amperaje del panel solar y de la batería por separado. En esas fotos vemos que el voltaje del panel está en 18.8V mientras que el de la batería está en 13.8V, porque ya no necesita mas. (Medición tomada a las 15:30hrs) Había usado durante años otros controladores que solo te ponen cuatro foquitos, y con eso no puedes saber casi nada sobre como está tu sistema, y cuestan prácticamente lo mismo.Tiene función para baterías de litio, pero no sirvió, la batería variaba el voltaje sin control en las horas de sol, y no prendía ni un mini ventilador de 2.0 watts. Pienso que fué por la mala calidad de la batería, no por el controlador.Creo que compraré otros de estos controladores para mis otras estaciones solares.

   It seems like a good quality 10A PWM charge controller.The LCD display shows the Solar panel voltage / Input Current in Amps / Battery voltage / Draw in Amps from the battery to output/USB ports.The USB (2A@5V) charge ports are controlled via the out-put terminals setting which can be switched on or off. It defaults to off if disconnected from the battery.The LIFEPO4 battery charge voltage setting is adjustable. Charging stops at that voltage.I will buy more.

    Excelente producto, por mucho una excelente calidad y funcionalidad, lo tengo conectado a una batería de litio pequeña pero es suficiente para una tira led y carga de dispositivos, ampliamente recomendado
