Hi is your epever inverter still working fine?

Basically...if you're building a large solar system, get a mppt charge controller. For a small 12v system, get a pwm charge controller and a extra solar panel for better results. Nice video. Brilliant explanation of how both controller work.

شكرا لك اخي الكريم

Hi, I live in Liverpool Merseyside England and I use an 80 watt solar panel to charge my car battery without a controller. I use a blocking diode in line to stop discharge into the solar panel at night ok. Because of where in live the solar panel never never puts out much more than 13.5 volts, so great video but you should mention the fact of where you live because of the sunshine. If you live in the Sahara Desert yes. Take care Walter from Liverpool Merseyside England

24 volt system changes the whole equation, 31.8 volt panels match very well to pwm for 28-30 volt charging...simplicity and cost effective. MPPT is good for voltage matching, that's the main plus ...thanks for the demo⚡

That’s a ripper

I wish someone would open up the backs to show the difference

Good info.

Nice tour of your system.

so you mean you're charging lithium battery using the epever mppt solar charger with the engine alternator/genrator?thank you

Hey dear I am facing power dropping issue in series connection. I have connected 340watt and 380watt solar panels in series to epever 40A mppt controller with 12v battery. It show power of one panel when I disconnect solar connector and reconnect, the mppt show both Panels. It’s hard to do this every morning. It was fine in winter but now summer starting and facing this issue. Using both panels form 2 months. after wire disconnect and reconnect the voltage jump from 33-36 to 75v. If something wrong with one solar panel then it should not work after replugging mc4 or solar wire in the mppt after that It work whole day but same issue next morning Both panels volts amps are little different. Tesla 34.51v maxpower 33.18v. Tesla amps 11.01amps maxpower 10.29amps.

i bought a 550w (46v)solar panel and a 300w power station. my power station can take 100w (12v) from a solar and my solar panel is 550w (obviously too much). what do i do in this situation? i want to reduce the power of the solar panel to balance out everything with my power station.

Hey, in the video u refer to the other test between mppt and pwm but with 12V panels. Is this video no longer available? Thx in advance

Hello friend, how are you? My MT 50 works normally with the solar panel OFF, but when I turn the panel on it restarts. I turn off the panel and it goes back to normal, the 40a Epever is normal, charging the batteries, inverter ok, everything works, what could it be? I tested with another network cable and the same thing, it's as if when connecting the solar panel the voltage on the RJ45 changed and it restarted.

is a controller the same as a regulator?

Based on this experiment, I will not use high voltage panels arrangement with pwm controller. Thanks for the information

Better and cheaper panels cause mppt can use 240v panels

Hi Don't hide cabes behind!!! This system is designed for mountain outside and easy getting overheat.

What setting should I use for pure lead battery

Circuit breaker should not be used as a switch.

I believe if your just wanting a maintenance charge on some rv batteries the ppm controller should be just fine 2 panels wired parallel

This Video Explains in very simple layman's terms why an MPPT is the better option. Along with a more detailed explanation. He does this in just over 5 mins. BRILLIANT > thank You so much . If this was an American Guy or Shiela (LOL) explaining, we would probably be 30 mins plus. Thanks Bruce

26W from PWM in this example. If you use 24V battery, it would be 52W, because from MPP down, power is almost linear. Basically no difference between PWM and MPPT, or maybe 2Watts would be with those panels and 24V battery.

Does generated energy kWh reset daily by itself?

Good info.

I wanna add a system to my semi truck, it has 3 battery’s in parallel I think it’s called???

This is true practical demo which i was looking for. Thanks

Hey man! Thanks for the video... i have a question, i just connected an Epever 40 amp xtra 4210 on a flooded battery... the battery manufacturer said that the lowest the battery can be discharged is up to 11.7 v... how can i set that parameter into the controller!?

Great video mate , can I simple just run my lipo4 battery on sealed or gel whilst I get my mt50 in 2 weeks

Trop rapide on a pas le temps de lire la tradution

Hey man thks for the video , i got the load terminal conected, when i press the power button turns the load off right. But says the battery is 56 % soc, when i press the power button again turns the load on, but now the battery says is 86% soc, i dont understand that part , how do i know wich is the real soc and load should be of or on when i charge the battery. 120ah lithium.Thks mate

Nice set up, mine is similar but still not finished. I do have a question. The XTRA controller has a default charging profile for LiFePo4 batteries. the 8s/24v default profile, among its many parameters,,bulk charges at 29.2 volts and float charges at 27.6 volts. Why do you see a need for the MT50? I have one but my Amazon return window is closing. TIA.

Hey mate. Question on the breakers in your videos. I'm putting a Noark Switch MCB DC 2 Pole 40A 360V non-polarised breaker on my camper van. Same model as you have here, a Ex9BP-N. Do I just put the 8 B&S - and + from the solar panel into the bottom of the Noark, (one each side ie. one to each screw) then out the top (load side) then connect the MPPT solar in via Anderson plugs like you wired up here?. (I want to protect MPPT and be able to isolate panels with the Ex9BP-N). I'm thinking of adding Andersons 50a connectors to the breaker wiring too, both ends so will have permanent Anderson connectors each side (input and output) of the breaker. Any issues in having Anderson connectors attached to the breaker wiring? reason, my MPPT then can be unplugged and taken out into the portable solar when not taking the camper trailer with me, example: going to the beach and just taking fridge, solar panels and battery, and of course the mppt. Also, last one, why the different breaker with red switch lever and not to same breakers ie. both Ex9BP-N's? Cheers!

MPPT also uses more power than pwm. So you are not getting a whole lot more.

Hey bud, been looking everywhere for an answer to this so I hope you can help out. I have 2 x 105ah batteries in paralell. Do I set the ah on the controller to 105 or 210 as there are two batteries?

i'm stumped on setting the load and float

Hello, could you tell me, how did you install the temperature sensor? Thanks.

It would be nice to give a link to that manual site that includes lithium settings. because I can not find it.

Oi mate. I wonder. If I do a set up like that On a solar system I’ve got run out of my shipping container shop ! I wonder if I can just ground the battery to the container And run my power out to lights and shit just with a positive wire Then ground the light or what ever to the container ? I’m not a sparky aye But sounds fair dinkum aye ? Like a car set up. Negative ground ? Whatta reckon?

Mate i wish it was that easy. Im using user 24v lithium iron 18650 cells and after 2 hours of playing i cant get it to load. No matter what i do i get a para error. Its driving me nuts.

What lights are supposed to be on?

Great simple set up, helps a heap. Could you show / explain how the circuit breakers were installed on the wooden board? I can't find the DIN rain and looking to find a solution to install it on a a plywood.

I have downloaded the parameter for LIFEPO4 but they don't give anything for Equilize duration and Boost duration, what would be the correct numbers? Where did you get your numbers, they are different than the ones in the manual. Thank You for this video!

For small systems PWM is adequate. If you want more amps from PWM add another solar panel to compensate.

note I already have one of the panels, the EPever controller and the AGM batteries. As I'm intending to be sleeping next to this lot, safety is the most important consideration - even more than good value!

Thanks mate - that's a good introduction for non sparky blokes (which is me). I did buy the Epever and mt50 for my first van conversion system - but Im considering my second more ambitious van conversion. First I have to resolve which DC to DC charger to buy that works with my current EPever solar charge controller - any advice welcome so I don't buy the wrong thing. In your shed I'm thinking that a bit of insulation on the inside roof and or walls wouldnt go amiss - it must be unbearably hot in there.

Hello bro I have Xtra 40 4415 can I attach 2 panels of 380watt in series or in parallel for maximum output. Will it damage the controller?

Great explanation, really helps newcomers like me. Cheers from Brazil
