Review: Extremely Rugged and Dependable - I've been using Renogy products for 3 years now. I boondock all winter in the Arizona desert powering an old RV with 4 100w Renogy panels. For two and half years I had been running my solar through a Rove 20a controller. The conditions were such that I was constantly exceeding the limits of the Rover 20a unit, often feeding it over 25a and it never complained. I finally smartened up and upgraded to the Rover 40a and it is doing its job perfectly. My only issue is with the bluetooth module. It was constantly needing to be unplugged and plugged back in to be reset. This appears to be a generic bluetooth issue that is not limited to Renogy controllers. My simple fix to keep from having to go outside to do the unplugging was to take an Ethernet cable that I had hanging around, plugged it into the controller and ran the cable into the RV. I bought a cheap connector to join it to the bluetooth module cable and now I can comfortably reset it as needed without going outside and crawling on the ground to reach the charge controller. The Rover controllers are quite rugged. I run fans in the bay where my controller, inverter and batteries are located, yet the temperature will often get to 125 degrees. That's in the desert in the winter! So far, so good.
Review: Well priced Controller - a definite must for small-scale/camping solar applications - Great replacement for the PWM controller that came with our Renogy Solar kit. Initially we had the Renogy PWM 30 AMP controller and it was an entry level controller in all respects. The previous controller was limited to a 12 volt battery source had 2 lead pairs, one for solar panel connection and the other for the battery side connection. Any load connected to the battery array had to be connected directly to the batteries and was not governed by the controller. Also you had to rely on LED indicator lights To determine when the controller was in charge mode versus float mode. Adequate for an entry level controller but not great. Now lets talk about this controller. First, this controller is capable of 12 or 24 volt wiring installations. 24 volt DC is superior to 12 volt DC because it cuts the Amperage draw in half on the DC end. A 1.2 Amp TV running on AC/120 volts will require 12 Amps on the 12v-DC end to meet the same 140 Watt requirement. A 24 volt DC setup will reduce the amperage requirement down to 6 amps on DC, which means your DC wiring gauge doesn’t have to be as robust when supporting a 24 volt application. Secondly, the LCD display is great and is a must for a solar charge controller. It’s not enough to know that the solar cells are charging the battery, you may also want to know how “fast” they are charging the battery and whether or not the panels should be angled to reach optimized charge rate. The LCD screen also provides a percentage estimate of battery remaining in addition to the amps that are being supplied by the panels, along with a running amp-hour accumulation of charge provided the panels over a period of time and current battery voltage. Third, it has a pair of positive/negative load leads that permit connecting appliance loads up to 20 Amps DC. It’s not necessary to use the load leads for connecting the devices that run off the battery, but the added advantage of using them is that your battery array is protected from over-consumption, as the leads shut off usage on the battery once it reaches a certain level of discharge in order to protect the battery array. I’ve only used the new controller once, but the instructions were easy to follow and I made a laminated copy of the LED and Menu options as a quick reference guide that will go along with the kit on camping trips. Currently the array powers my 400 Watt (4x100W) kit and 2 VMAX 125ah batteries wired in parallel, but I am seriously thinking of doubling the panel array and adding 2 more batteries in a series/parallel configuration to take advantage of the 24 volt capabilities of this controller. Quick Note on the 100 Watt Renogy panels: When I measured the charge current of the 4 x 100 watt panels connected in Parallel I noted an 18.5 amp charge rate on the new controller or ~4.6 amps per panel. That seemed low to me given that 400 watts/12v is around 33.3 amps, or 8.33 amps per panel. In discussions with Renogy support I found out that the 100 Watts is calculated at 17.9 volts * 5.7 amps, where they use the maximum charge voltage by each of the panels as basis for the calculation. Just something to be aware of when you are reading sub-5 amps per panel charge rate on your controller. This new controller works as advertised, was relatively inexpensive for what it does, and I may update the review again in 12 months after running it a few more times for a consistency check.

## Questions & Answers

**Q: How should I wire my panels with an MPPT charge controller?**
A: The panels can be wired either in series or parallel or a combination of series/parallel.

**Q: What is the max wattage input on the Rover 40?**
A: The Renogy Rover 40A MPPT Solar Charge Controller can accept input of up to 520W for a 12V system, and up to 1040W for a 24V system.

**Q: Does the Rover 40A MPPT charge controller have a built-in 40A fuse for the rated 40A load output?**
A: No. Please always add a fuse between the charge controller and batteries. To determine the fuse size, you can match it to the amperage rating of the charge controller. If you have one of our 40A charge controllers, we recommend using a 40A ANL fuse.

**Q: What are the advantages of Renogy MPPT technology?**
A: Renogy Rover Series solar charge controllers use Power Catcher MPPT algorithm to always ensure the charge controller converts most energy by locking to the most optimal maximum power point.

The price you pay seemed high until you set it up and it just works. It took a few minutes to get the setup right but once it's done it does the job very well.
