Don't mount the box until you have looked at how the terminals work. I got confused was turning the screw left almost busted out the plastic. I didn't look up under there and turn it see how it worked. There is a metal tab that screws up grabs the wire. I receemoned if you can screw all the wires in first while its flat before you mount it on the wall.

[@Desertphile]

Thank you. I do not understand why people spend more for Renogy when similar chargers cost less.

[@ironian24]

its because they are great quality with far more features and power than the cheaper ones. in my opinion there is only 2 real contenders for my van power, Renogy or Victron, I started with Renogy so I carried on with it through the whole of my electric build, I am very impressed with the build quality, the plug and play side of it all, the easy to follow instructions, the power production, the ease of use, with either apps or panels it's easy to see what your electronics are doing.

do you need breakers or fuses from the solar panels and to the battery? or is there an internal fuse on this unit? I just installed mine with no fuses because i thought there was an internal fuse, I have 2x 200 watt panels going through the 40amp mppt unit then to the 200amh lithium ion battery, all renogy.

Do you know what happens to the controller if the battery power is lost do to the battery shutting down or disconnected unexpectedly ? If this needs to be powered first from the battery.

[@penelopegreenland3537]

Trying to decide if I should hook my 3, 100watt panels in parallel when using a renogy rover charge controller. I am in an area with intermittent shade. I ran it on two panels in series last year and did not get enough stored energy to run appliances on cloudy days. Awesome explanations!

[@MarkWilliams-ix1qf]

Parallel if you think shade is likely. You have more wire loss, but not a shutdown as with series.

[@robertsullivan9501]

on the home screen what should the battery voltage read and what mode tells you the solar panel is charging the battery and how much, i am new to this stuff, also if using two deep cycle batteries in parellel should you charge them both before using

[@timkempowski7012]

Do you know the max amp draw from the dc load? Mine trips and I’m trying to pull peak 10 amps which I don’t think is that high for DC, so yeah low draws on the load out side. Great video just wish the lighting was better. Thanks for the video

Hi I have the same Renogy controller and getting ready to install it with my inverter. Very informative video and learned more about my controller so I know whats going on. One question though, I bought one lead acid battery and was told to watch it not go below 1/2 charge. I believe the controller has the ability to tell me on teh screen if its at a certain charge level or bars or do I need to buy a separate battery monitor, would not be a bad idea to buy one when I have more money though.

[@GHE2005]

So if I plug in a iCeco 20 frig is that considered a heavy load? I'm not understanding "a load"? Did I see u plug some socks into your load? R they USB sockets or outlets? Thank u for all the details explanation.👍🏾 I don't hv much knowledge about controllers.

[@jiujitsu2000]

Switch

i hope you didnt use a switch between the battery and controller that will likely fry the controller at some point. you want the switch between the panels and the controller, if you want to stop charging.

[@cleangreen2210]

@@jiujitsu2000 Thanks! What it seems like now is that you have to take the settings from the battery manufacturer and divide them in half, then you change the battery type to LI and the voltage to 24 on the controllers. Renogy says this is because "sometimes" the charger controller does not recognize the 24v bank. After trying this yesterday it seemed to work, as I stopped getting low voltage errors and both batteries charged together.

[@Junkie4Jesus777]

Hey bud, I’ve watched this video 3 times as I installed my rover 40 amp and I just can’t figure out why it’s always on night mode as I purchased it new and am getting 20.4 V from my panels and it’s even reading 20.4 V when I touch my meter to the panel jacks on the left hand side right next to the battery temp sensor so I know the rover is getting the juice from the solar panels but for some dam reason it won’t change my batteries because it’s always showing the little moon icon on the top left of the screen and it’s 77 degrees out without a cloud in the sky and not a single square inch of shade on either of my 8 panels as this will work on 800 watts as long as you run the batteries at 24 V in series. Do you have any ideas as to what the heck is going on or how to maybe reset the controller to factory or hell I don’t know anything? Thanks so much 🙏🙏🙏

[@bradlyons7046]

When using lithium-ion 12V battery and using the control button(s) on the controller to select 'Lithium' as the battery type, does the controller know everything else it is required to know for using a lithium-ion battery? Or is there additional programming required for the controller to work properly with a lithium-ion battery? For example, Will Prowse mentions in one of his many KZbin videos about DIY solar set-ups, that he favors the EPEVER Tracer MPPT solar charge controller, but mentions it is too complicated to program it when using a lithium-ion battery instead of a lead acid battery. Does this Renogy MPPT 40A solar charge controller have similar excess programming complexity as the EPEVER Tracer 40A MPPT solar charge controller when using a lithium-ion battery instead of a lead acid battery? When using more than one lead acid battery connected to the same MPPT solar charge controller, is more than one battery temperature sensor needed to monitor the temperature of all the batteries? Please explain what the 40A (40 Amps of current) rating of this Renogy MPPT solar charge controller refers to. For example, does it refer to the maximum number of amps it is able to control coming from the solar panel(s)? The EPEVER Tracer4215BN MPPT controller is a 40A solar charge controller and has a maximum discharge current (the discharge current to the load) of 20A, not 40A. What is the maximum discharge current of the Renogy 40A MPPT solar charge controller? 20 amps? 30 amps? Please explain what the term 'maximum discharge current' is. For example, is it the maximum number of amps (maximum amount of current) it will allow the solar powered devices to pull from the controller and / or battery? Please explain. I ask these questions for the following reason(s): I want to build a direct current 12V portable outdoor solar powered swamp cooler using two 12V, 120W, 10A automotive radiator fans wired to one or two 20A motor speed controllers (potentiometers). A person told me I need to allow for momentary surge of excess current (momentary amp surge) each time the two 12V, 120W, 10A automotive radiator fan motors power-on; however, I am wondering how much of an amp surge the fan motors will momentarily pull on the MPPT charge controller, and whether or not one or two 20A motor speed controllers wired to each fan motor will help prevent the amp surge on power-up of the two fans. The submersible water pump will be 12V, 20W, 2A, and will be wired to a toggle switch to turn on & off. I will be using four 12V, 100W, 7A portable briefcase solar panels connected in parallel which will provide 400 watts, 28 amps at 12 volts to whatever MPPT solar charge controller I end up choosing to use. I want to start out using 12V sealed lead acid batteries, and eventually switch to lithium-ion 12V batteries. For this reason, I have decided not to choose the EPEVER Tracer brand MPPT solar charge controller because it is purportedly too complicated to program when using one or more lithium-ion battery. I presume I need to choose a 40A MPPT controller instead of a 30A MPPT charge controller, but perhaps a 40A MPPT charge controller is not enough amps either for my swamp cooler. Do I need a 60A MPPT charge controller? What's your opinion? I invite anyone to leave a reply to my questions. Thank you.

Can you show how it changes when you put loads on the batteries? My battery screen shows 100% all the time but when we plug something in, the discharge A and AH stay 0 but our battery capacity jumps around between 50% and 100% it makes no sense

[@akauto2900]

Is your load going through the charge controller, or is it going through an inverter? To display load information, it has to be from the load output on the controller. However, it can't handle a heavy load.
