Renogy Wanderer

Son cargadores solares de excelente calidad y modernos, vienen hasta con número de serie, funcionan muy bien con batería LiFePO4 y además vienen con la función de TIMER, los recomiendo ampliamente para cualquier tipo de proyecto fotovoltaico de iluminación.

I have an IRLP node with a 12V lithium battery for backup should the power go out and I needed a charge controller as the DC in I have is about 20V, which is naturally too high to simply directly connect. This controller is exactly what I needed. It will do SLA, flooded and lithium chemistries, you need to select type of battery manually, and you can dial in what charge voltage you want, in my case, according to the battery I have connected, it wants to see 14.4V. You can set up the LCD readout to display what you want for the most part and it has performed flawlessly since I have had it. The instructions are fairly clear on what you need to do to set it up and it actually is pretty easy. It has worked well during outages, switching from the input source to the battery is seamless. I am very happy with this controller and have already recommended this brand to my friends that were looking for one for their various reasons.

Quick delivery. Efficient solar controller.

Without a doubt and after testing most of the PWM controllers in this realm, I'll say this one is the best. This one not only works, but you don't have to worry about it and it just works. It's also a great price for 17$ which is what I paid. If you are looking for a charge controller either for a backup or just because you have less than a 200w panel or two 100w panels in parallel this little controller will fit the bill for you. You can add the BT controller if you want but why? That costs more than this unit and this unit already has this data built in. Just press the select button to see voltage, amps, battery voltage, load, load settings and ways to maximize your small setup with a excellent PWM controller. Thank you Renogy for this controller and please keep this low price for all of us that know how to properly use this. This is seriously the best sub 20$ PWM controller out there for small panels and it just works with all the features it provides. I'm very happy with this unit and would highly recommend to anyone.

From my initial internal review and power up, devices seems good value. Board is conformally coated, giving some protection from excessive humidity and corrosion. All negative terminals are bonded together proving Negative Ground. GEL is the most useful mode, as it will not EQ, and voltages remain OK... Boost will aggressively charge the battery 14.2, and float is 13.8V. Note that the Lithium voltage is adjustable, so if you simply want to set a fixed voltage without any temperature compensation, you can. This unit will also control a night light, including a fixed time of operation (say 4 hours after dusk) then turn off to save the battery for the next day and to reduce battery wear. Unit shuts down output at low battery voltage. For hackers that want access to the RS232 port, search for ROVER MODBUS.DOCX for the published modbus registers. Despite the manual mentioning temperature compensation, there is no sensor input, so it isn't clear if an on-board sensor drives this feature, or it is missing (I'm OK without it).
