RenogyRover 30A 12V/24V Auto DC Input MPPT Solar Charge Controller Parameter Adjustable LCD Display Solar Panel Regulator fit for Gel Sealed Flooded and Lithium Battery, Rover 30A,Black

Quality product, does what it's supposed to do and easy installation.

This is a great solar controller!I haven't completed my DIY solar setup just yet, but this controller works great for charging my (3) 12v AGM batteries in parralel. I'm using two 32v 250watt solar panels wired in series so the controller is getting maxed out at charging the batteries at 20 amps! I was not expecting my solar panels to max out the controller but it is limiting itself properly and keeping the batteries charged and ready to go! Even on a grey cloudy afternoon, it will trickle charge the batteries around 2 amps.Do not believe the other cheap charge controllers showing 50 or even 100amps of capacity because they do not use the proper internal circuits to actually handle that amount of power.PLEASE NOTE: the power output terminals on the controller are NOT for high load applications. If you plan to use them for an inverter or high amperage load, it must be wired to a contactor or relay to avoid frying the controller. The instructions provided have more information on how to properly use the output.The setup instructions provided are easy to follow and the online support, and manufacturers website are very helpful. They make great products all around.Again, this is a great controller and you won't be dissappointed!

Meets all specifications, MPPT tracking and voltage down conversion from PV module voltage to battery voltage conversion works well. Efficient, at least 90% of PV module power goes to the battery (note: cheaper "PWM" chargers burn off excess module voltage, wasting this power, instead of converting it). Pre-programmed Lithium battery charge settings work fine. Screw terminals are easy to use and make secure connections.I mounted this unit to the outside of a Group 24 battery box, which I use with a 100W module and a 100Ah LiTime battery for power in remote locations; the combination works very well. Big, easy to read display. Menus and buttons are intuitive and easy to learn and use. Well made. Easy to mount. Includes temperature sensor probe for battery temperature compensation. Good value, I would recommend it and would buy it again.

Does the work well

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.

Initially, I bought a Rover 30 for my solar panels back in 2022. It failed after 6 months. Renogy would not honor the warranty because they said the charge controller for my wind generator voided it, even though there was nothing in the warranty language that prohibited it.After 1.5 years with an unbranded hybrid MPPT that could take wind, I decided to take the wind offline, add two more panels. The Rover 40 seemed to make sense in that application. I hoped that this time the Renogy, which does well in converting high voltage low amp current from the panels to 24V/high amp charging current, would serve its purpose well.For the first couple weeks, it did very well. But now about once a day, I have to take off, reposition, and re-connect the battery cables. It work fine for a while, and then stop charging. Then I am running straight off the batteries until they run down. Seems the battery cables will not stay connected despite my best efforts.I've noticed in different reviews, others have also had issues with their terminals. One person complained that the screw stripped out, which suggests to me they were trying the get a good, lasting connection. I don't think this problem is unique to me.Since I am still within 30 days and since I had poor experience with their customer service previously, I'm not taking any chances. I've orderd a Vectron to replace this, and as soon as it arrives this thing is going back into the box and back to Amazon.No more Renogy products for me. I'm done with them.

Great product great price

This is great I have been using it for about a year and had no issues.
