Renogy New Edition Voyager 20A PWM Waterproof Solar Charge Controller, 20 Amp

Works correctly.

Ok this is not an MPPT controller, but we're talking low amperage here, so the difference with a good PWM like this one is quite small. But the price is incredible for a perfectly good waterproof controller that is programmable for different battery chemistries, and an LCD display! Connections are well protected, and I've been using this for 2 months and it's doing great with my AGM marine battery. I just wish Amazon can have it back in stock soon, will buy more.

Very well written instructions and all i need to keep my 2 AGM 105 ah batteries in my rv fully charged. I think mttp controllers are overkill to keep batteries fully charged while boondocking. You just have to manage your consumption.

Received it recently so don't know about its longevity, but so far it has worked great. It's connected to two 160 solar panels, which are connected in series. So far, the input voltage has not gotten above 40 volts, which is well within the range of the 52 volts max input voltage of the charger. The battery it maintains is a 20A 12 volts Lithium type battery. Installation is simple; connect the battery and then the solar charger. It comes with a small clear and precise manual; a PDF manual can also be downloaded. Pros; it's easy to make adjustments, including selecting battery type, thanks to the included manual. When first plugged in, at least in my case, AGM battery was selected...perhaps its default setting. Cons; does no have a load input connection, so the load must be connected to the battery. This requires a separate switch to turn the load on/off. So far it has worked and I recommend it.

Gran producto, lo recomiendo!
