Efficient 20A Solar Charge Controller with Adjustable LCD Display for 12V/24V Solar Panel Battery System, Intelligent Regulator featuring Dual USB Ports Review

Works. and no complaints for this price. I bought a used 100w panel and this is for my caravan. Can't confirm weather resistance as I keep them indoors with the batteries. I want it to show how many amps go, or even how many batteries, and it could be. Maybe I just haven't read enough.

The main function of the regulator is to regulate the battery voltage. This allows producing as much or less than solar panels. The default value of 10.7 to 13.7V floating point has been tested and validated. Battery reaches 15.9v. Outside of Revain's return window and not having the patience to attempt an exchange from China. Just take my advice and buy something else.

After charging this controller to 14.4v by 10am for 3 days, I boiled the batteries in there all day without them dropping to the advertised 13.7v. I dropped the Floating Voltage, turned it off, and returned it. Binen US, the seller, was very responsive, but their supplier, presumably the manufacturer, still denied, claiming that 14.4v is normal. Installing a competitor solar controller in the same system and dropping it to my set float voltage of 13.5 volts at 10 am disproved this. Bad design…

I've been living offline for 26 years and I'm very familiar with charge controllers and batteries. This controller does not float at 13.7V as configured and instead keeps the batteries at 14.4V which is way too high and potentially very dangerous. We spent almost a day getting it working properly. It was also difficult to make a secure connection to the stranded wire as the clamp only allows a tiny bit of wire to be inserted - I suspect they will come loose quite often. The instruction manual…

I replaced a basic charge controller that was not charging my 7 amp battery with this charge controller. It's WAY overkill, but works so well I don't care, and costs $2 more than the one it replaced. The system I have is a charge controller, 12 7 amp battery, 5 watt panel and 150 watt inverter which I wired up in the box. I set up a switch to power the inverter so I can quickly charge my battery with my 5 watt pad. I use this setup to power very remote locations to power my cellphone and laptop

This is a good controller but let me share a few things with you if you plan to use it with a 12v solar panel: 1) When you turn it on first on a bright day Plug your solar panel in and the peak voltage is about 20 or 21 volts. The "smart" side of this PLC will think you have it set to 24 volts. You can't get any output if you connected the 12V battery now. You can't drop the charging voltage down to 12 volts because it's in 24 volt mode. Restart PLC. .3) Now connect the 12V DC battery first…

I have been monitoring the solar charging system (using 2 charge controllers for the whole system) for several days and it is working very well. I am using a 1 x 100w solar panel to charge 2 battery systems. I am charging a 12v RV chassis battery (controlled by a charge controller) and 2 x 6v RV batteries (connected in parallel to get 12v) (controlled by a second charge controller). The chassis battery finished charging this morning as it was fully charged and thus provided a full charge for…

As you know, the role of the solar controller is to regulate everything between the panels and the battery. When the battery reaches the controller's "pre-programmed" cut-off voltage, it is assumed that the connection between the solar panel and the battery is broken. For example, I have an AGM Deep Cycle battery and the solar controller is programmed to slow the charge rate after the battery reaches 13.7 volts. Well, the only time I relax is charging my laptop with the inverter when the…

I did a little surgery on mine to fix an issue where one of the MOSFETs wasn't touching the back panel. I bent them forward a bit and put a piece of shrink tubing behind them to hold them against the plate. Some of the people reporting these errors are most likely due to the FETs not touching the metal backplate and overheating. People who complain about wiring harnesses don't open the clamps before trying to tighten them I guess. The clamps are closed, you need to turn the screws…
