Renogy Solar Charge Controller Rover 20A 12V24V Auto DC Input MPPT Charge Controllers for Solar Panels Adjustable LCD for Gel Sealed Flooded Lithium Batteries | 95V PV input, AGM/Gel/Flooded (auto), Li (manual), MPPT 99% tracking,overcharge/short protection, negative ground, for RVs

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.

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!

I replaced an old direct from China PWM converter with a Renogy Rover 20 amp for my camping solar rig. The improvement has been pretty remarkable. I'm really happy with the configuration, efficiency, and safety of this design.The efficiency gain going from PWM to MPPT is noticeable. More importantly for me, the ability to program the charging parameters from a laptop allowed me to use a custom lithium battery pack and get the target voltages exactly where I want them. I camp with a 70 Ah lithium pack built into a "suitcase" with the the Renogy Rover, fuse box, switches, inverter, etc. A big selector switch in the box lets me swap between my internal lithium and an external sealed lead acid batter for those times when the weather doesn't cooperate, and I need a little more juice. The Rover easily switches between "SLA" battery mode and my "USER" mode for the lithium. Best for me, the protection circuitry in the Rover shuts everything down long before voltages get anywhere near damaging my lithium if I forget to switch modes.The only knock I'd give on this controller is that the software to configure it is pretty rough around the edges. I had to reconnect and reboot frequently as it lost sync with the Rover, and the initial setup of the software isn't intuitive. Read the Fine Manual... The software is Windows only as well which is inconvenient for a Linux/Mac user. Still, after a bit of fiddling & testing (with a bench power supply standing in for solar panels over this LONG winter), it configured the Rover to the exact charging parameters I wanted for my lithium. All the settings are remembered when the controller is powered down. I'm ready to camp this summer!

This works well to charge LiFePO batteries - but you have to change the settings. The default "Li" (Lithium) setting doesn't do it. I don't know what logic it applies in the "Li" setting, but my LiFePO batteries went dead. Once dead, the controller would not apply any current to recharge them. I had to change the battery type to "USE". The "USE" setting allows you to set the battery charging parameters - Equalizing voltage (which you can't shut off, but doesn't apply to LiFePO batteries), Boost voltage, Floating charging voltage, over-discharge return voltage, Over-discharge voltage - to your LiFePO battery's specs. Once done, they charged very quickly and stayed that way. LiFePO batteries typically have a built-in BMS unlike Lithium Ion batteries. Also, the manual that comes with the unit is nowhere near as detailed as the one that you can download from here (or Renogy's site). What's included in the box is pretty much a quick-start guide that doesn't get into detailed settings.

I have a couple larger systems, but had a need for smaller system (i.e. cheap). I'm using a single 200W panel and a single 12v AGM battery.My wire connections are 10 AWG from the panel, 8 AWG to the battery. No issues at all with the terminals. The holes in the case are slightly offset with the terminal lugs, but it doesn't seem to cause any problems. But I wish they didn't use phillips screws on the terminals; you must use a high quality bit that is not worn out, or it can slip.Programming is fairly simple, although it takes a minute to understand the logic behind the button sequences. Once you get their logic, it's easy. Runtime data is displayed by pressing the up/down buttons to view each parameter. There's no backlight, but the display uses large digits and you can pretty much see it in any lighting condition except total darkness.I don't use the load function, but I did test it up to about 15A, and it worked fine. As the manual says, the load is not for inverters or high current loads, and you shouldn't be using loads with a low PF, inductive loads, etc. The load is really for a light. You could also do something like connect a relay, and have a cooling fan turn ON during the day to keep the system cool, and off at night.It works great for what it is - a simple MPPT charge controller. If you READ the instructions, everything you need to know is there. For example it tells you that no equalization occurs when the unit is set to "Gel" (for AGM cells), yet I still see people confused about this. It is not waterproof. No mounting brackets are included, you just use some standard screws. A battery temperature sensor is included.

We bought this to pair with our solar powered blanket and it works as its supposed to. You can download the app and it tells you the state of charge. Its not too big and we hardwired it into our trailer. The Bluetooth works as advertised, great value for money spent, charges the trailer battery and is quiet.

I use this with a 300W folding panel on a 100' cord to help charge my batteries on my RV. When in direct sun I get a 20A charging rate so the batteries charge up fairly fast, I like the app BT connection for changing from flooded wet cell to gel or lithium batteries and monitoring the charge rate and battery state. Used it on one long and several short trips and it works great as a backup to my rooftop solar or supplemental charging source, and as it folds flat and has built in leg stands it is east to store in my pass-thru compartment.

So unbelievably user friendly! Easy installation and works perfectly. I am a solar novice and this was super easy.

Robusto ben fatto, completo di tutte le funzioni indispensabili per un mppt stand alone. Il dissipatore di calore è ben dimensionato e non necessita di ventole visti i rendimenti dichiarati dalla casa che credo siano corretti anche sulla base dei test che ho fatto. Inoltre il modello 20A gestisce potenze tutto sommato modeste ( 480w con batterie da 24v). Il display è a cristalli liquidi senza retroilluminazione con tutti i problemi dei cristalli liquidi. Di giorno e con vista frontale sono nitidi e chiari, con vista disallineato non si riescono a leggere. Non è che uno sta sempre lì a guardare il display, una volta impostato si controlla ogni tanto. Con l'app questi problemi non ci dovrebbero essere, però occorre comprare un ammennicolo wifi da aggiungere. La morsettiere fa il suo lavoro ma forse si poteva fare meglio. La programmazione è un po' macchinosa visto che si deve entrare nei vari menù, scorrerli fino al parametro di interesse, modificarlo e salvarlo. Vero che si fa una volta sola, ma è un po' noioso. Sul display di possono vedere tensioni e correnti gestire dall'apparecchio ma mancano statistiche più accurate, credo che sempre con app e ammennicolo il problema si risolva Cosi come la programmazione. Per me l'apparecchio va bene visto anche il costo di acquisto scontato ed è certamente completo per l'uso stand alone. Al prezzo di vendita pieno , senza sconti, si trovano apparecchi più completi con wifi app incluse.

Super Teil. Läuft schon Jahre ohne Probleme

独立型の50W太陽光パネルで使っていたPWMチャージコントローラーが壊れたので、その代替として急遽購入しました。PWMコントローラーは50Wシステムを構築するテストみたいな感じで安いのを買ったのですが、十分使えていたのでどっちにするか悩んだのですが、今は50Wパネルを本格的に運用していますし「MPPTで効率を上げるのはこのタイミングかなー」って思ってこちらにしました。しばらく運用してみたところ、発電量が多い時はそれほど変わらない働きですがMPPTの本領を発揮する「薄曇り、もしくは斜めから日が当たる状況」で随分と差が出ます。PWMでは余り発電しない状況でもMPPTだと結構発電していて、やっぱりMPPTは強いなと思いました。MPPTと書かれていても、あまり安いものは偽物である可能性が高いので、評価がある程度定まっているものを高くても買おうと思ってこちらにしたのですが、それが正解でした。長い期間使うものですから、少し値が張っても確実なものが一番です。

El equipo a falta de probarlo en producción funciona bien, la apariencia es de un producto bien diseñado y robusto, tiene una buena superficie de refrigeración y hay que tener presente que se trata de un regulador con una cierta calidad, se trata de un equipo MPPT y según mis pruebas básicas, realiza todas las etapas de carga perfectamente.He realizado las pruebas en el taller para comprobar los datos reales con el multímetro y la verdad es que todo los datos son reales a lo que muestra por pantalla, tanto los datos de voltaje, de potencia y de carga.Lo básico, (Tipo de batería, voltaje de trabajo, modo de funcionamiento de la carga), es configurable desde la pantalla del equipo mediante la combinación de teclas que indica el manual eso si, sólo en inglés.Viene acompañado de un cable de conexión RS232 a USB y que se utiliza para poder realizar configuraciones más complejas y que únicamente pueden realzarse utilizando el sofware suministrado por el fabricante. No viene ningun CD para su instalación, hay que descargarlo de la página del fabricante Renogy.El problema de este software es su instalación sobre Windows 10 como es mi caso, hay que realizar una serie de pasos ya que si no no os funcionara, imagino por es compatible únicamente con versiones anteriores de windows.Os explico un poco mi experiencia poder hacerlo funcionar en Windows 10 he hecho lo siguiente.Primero registrar los controles OCX que instala ya que no lo registra correctamente, para ello hay que ir a la consola de windows, (CMD), y ejecutrala en modo administrador. Luego registrar los cinco controles OCX:regsvr32 c:\windows\syswow64\MsComm32.ocxregsvr32 c:\windows\syswow64\MsComctl.ocxregsvr32 c:\windows\syswow64\Tabctl32.ocxregsvr32 c:\windows\syswow64\Comdlg32.ocxregsvr32 c:\windows\syswow64\Mschrt20.ocxuna vez registrados los OCX hay que modificar el ejecutable de la aplicación que lo encontrareis dentro de la carpeta del directorio de windows SysWOW64, (en mi caso C:\Windows\SysWOW64), pulsar botón derecho del mouse sobre el ejecutable "Solar Station Monitor.exe" y seleccionar las pestaña de compatibilidad en la lista de propiedades del archivo y modificar lo siguiente:Marcar "Ejecutar el programa en modo compatibilidad" y seleccionar "Windows7"Marcar "Ejecutar este programa como administrador"Recordar también e importante, no conectar el USB al PC sin antes haber cargado los drivers que acompañan al software que os descarguéis.Una vez todo instalado el software debería arrancar y para utilizarlo hay que seguir los pasos del manual que acompaña al software, la contraseña para el usuario administrador es 111111.Otro dato a tener en cuenta es que se suministra con una sonda de temperatura externa que se utiliza para tener controlado la temperatura del banco de baterías y que el regulador pueda actuar en consecuencia.No valoro con 5 estrellas el producto por los problemas no resueltos con la instalación del programa de gestión, pero una vez instalado es muy útil y funciona perfectamente.Lo recomiendo sin dudarlo, buen precio, buena calidad y buenas prestaciones BBB.EDITO 15/9/21Tras cuatro años de uso el cargador sigue funcionando correctamente y no me ha dado ningún tipo de problema, actualmente lo tengo monitorizado directamente con node-red mediante conexión modbus y va fantástico, he editado para dejar constancia de que se trata de un producto de muy buena calidad

Je l'utilise pour gérer 2 panneaux solaires sur mon camping car il est parfait les connexions sont solides très facile à utiliser . On a toutes les informations utiles pour surveiller la charge et la tension des batteries ,parfait
