Renogy Wanderer -- 30A Advanced PWM Negative-Ground Solar Charge Controller
- Enter your model number to make sure this fits.
- The Wanderer is a negative ground controller. This ensure compatibility with any negative ground system, which is the standard and most conventional way of grounding. Any negative connection on the solar module, battery and load can be safely earth grounded as required
- 4 Stage PWM charging (Bulk, Boost, Float, and Equalization) prevents batteries from over-charging and over-discharging. Protection against: overcharging, overload, short-circuit, and reverse polarity
- Compensates for temperature, automatically corrects charging and discharging parameters, and improves battery longevity.
- LED Indicators that inform you about the charge controller's status
- Compatible with Sealed, Gel, and Flooded batteries

The Renogy Wanderer is a 30A PWM charge controller. This advanced negative-ground controller is designed for off-grid solar applications and can be used with a 12V battery or battery bank. Integrating highly efficient PWM charging, the Wanderer increases battery life and improves system performance. The controller comes equipped with fully comprehensive self-diagnostics and electronic protection functions to prevent damage from installation mistakes or system faults. Negative grounding controller ensures the broader off grid applications and safety, especially to be used on a vehicle which has battery negative on the chassis. A little extra investment on the right charge controller will generate a much higher return and prevent system failure.

My use case for this controller is a bit atypical. I wanted a UPS (uninterruptible power supply) for some small electronics (Raspberry Pi, automatic cat feeder, modem/router, etc), but I didn't want to pay hundreds for the typical APC style UPS that came with an unknown inverter and unknown, potentially irreplaceable battery type. I wasn't sure if this device could be used as a UPS (that is, the battery would take up the load quick enough in the event of a power outage), so I just wanted to get something cheap to try it out. Turns out it does work, well.
I paired this device with a 120W 12VDC AC/DC power supply. This power supply acts as the solar panel (I may actually use solar panels in the future, but for now I have an AC/DC power supply so that's what I'm using). I hooked up an old motorcycle battery that I had laying around as the battery bank. I hope to upgrade this to an actual AGM battery bank soon, but since my loads are so low this will last for all of the basic few second power outages that would reset my RPi or modem/router. Then to the load side I attached some DC voltage regulators to output the various voltages that I need (5VDC for the RPi, 4.5VDC for the cat feeder, various voltages for the router/modem).
Overall this device functions well. I tested it with a 65w load and when the AC/DC power supply cuts out, the battery takes up operation in a quick enough time frame that my electronics don't shut off. There are lots of modes of operation, but I just use the manual one (6 I think?) because my devices need power 24/7. I can't say how well the battery charge functions because the motorcycle battery is pretty old and takes forever to charge, but the controller does charge it and maintain the charge well.
So, all in all, this is a good little device. My use is a bit atypical (UPS), but I'm surprised and happy to learn that this little thing functions just fine for my use.
EDIT: After having the system in use for a few days, I noticed the battery voltage was a bit low although the controller indicated it was "within range" (single green light). I did some research and learned that charge controllers will NOT step up a low input voltage to a higher voltage to charge the battery. The power supply I have caps out at about 12.99VDC so it looks like my battery will never attain full charge with this supply. I'm doing more research to determine a proper voltage for input supply.

- Hook it up and it works. Pretty straightforward to connect and operate.
- Lights are good to visually check whether panels are charging battery properly.Read more
