I charge over 200kWh of LFP every day using EPEVER, Victron, SolArk, Schneider, Midnite Solar. Adjust settings! They all run at varying efficiencies. Start up and shut down at different times. It’s just part of this fun hobby.

Did you notice the PV voltage on the EPEver is only 14.8v ? This is why it's getting such low wattage. Now question is why is the voltage so low? It's like the PV is directly connect to the battery. I wonder if it has a shorted mosfet? Or is it just getting poor sun, and in PWM mode?

I was thinking the same exact thing I have an EP ever and/or and never had that problem before something is definitely wrong with that side of the system.... Like my man said you're only getting 14 point something volts in from your solar panels so of course you can only pull so much amps from that, Seems to me you Need to isolate a variable. Something is not right on the epever side 🤔

@michaellemon8287

Yes, definitely something is off with these 14.8 volts. At 02:15 we can see 14.7 volts on the panels and it's no wonder battery voltage will not go above 13.8 volts because the manual says that the MPP voltage range starts at battery voltage +2V. So there would need to be at least 16 volts coming from the panels in order to reach 14V. I think in these conditions 13.8V is still a good result. Something is not right here.

I had two Epever controllers, one 100a and one 60a.the 100a failed, I replaced both controllers with Victron. Immediately noticed better overall performance. I’m on a boat, I originally faulted not getting full power from panels on angle or mast shadow. After installing Victrons I am now seeing full rated power from panels. The parameters were set the same on all units. I am very happy I changed units.

If you have both charge controlers hooked up to the same battery bus then they will influence each other. If the Victron is first at charging, it will raise the battery voltage, the 'slower to kick in' charge controler will see different voltages and hold back more. I have 4 charge controlers on the same 48V bus but they are controled by the Cerbo GX, it puts the MPPT RS units in 'External Control' mode. Besides, the Victron units have superior MPPT tracking :-)

I must agree with the other comments: If the PV voltage input is not roughly the same on the two controllers, its not an comparison as it is not the same conditions. If you would swap around the PV strings, so the Victron would get the only 14 volts PV input, then it would be the one looking faulty! (Victron may be a better controller, not so much doubt - but there is something wrong with that PV string on the Epever in this "comparison")

I know this may be just something I would try and may not do anything but might try switching the two strings and see if it’s still the same. Just to see if you have any issues with them. If not I’ll be waiting for the new victron controller replacement video. Have fun stay safe.

I have experience with both of those charge controllers paralleled together. If you didn’t notice your float voltage was set to 13.8 on the E Peever that’s why it was throttling. You could change the setpoint lower on the Victron and then it will start the throttle and the E paver will just provide the bulk of the current. There is no problem by the looks of it to me.

Hi, I appreciate the dedication, but I'm sorry but everything you show and the considerations you make, from the moment of the end of the first phase, do not make any sense. Only in the first phase do the controllers work in mppt. In absorption and maintenance, as long as they maintain the phase target, mppt tracking has nothing to do with it. Haven't you noticed yet that your panels have unan Vamp of about 72v (changes with the temperature) and that you can only see it in the first phase? Didn't you see that in absorption and maintenance it goes up to 86v? Do you think Chen changed the Vmpp of 20v in a second? Mppt stands for Maximum power Point tracking . To find the precise voltage that produces the maximum power in all light and temperature conditions. In absorption and maintenance, unless there is a large load, by definition it does not extract the maximum power. So there is no tracking. and the panel is allowed to rise at a voltage at which it cannot produce maximum power.But at this stage the controllers have no modulation. it cannot be a better or worse one (except in conversion efficiency. In addition, the comparison makes even less sense if you do not detect the voltages on the battery and do not say the targets of assosorption and maintenance of each . Do you want proof of all this? Put the victron with 0.2v absorption less than the epever. you will see that it will be the victron to give 0A and epever will give everything necessary. Are the wiring harnesses perfectly symmetrical? Impossible. so in the apse and float you will never see both contribute. except in the case you turn on a load such as to lower the battery voltage and regress in the first phase. in that case both contribute. but always according to the law of ohm.The epever problem is only one, and I explained it in a previous intervention. However it is very complex. if you do not fully dominate this that I talked about now it is even more difficult They always give magical powers to the controllers and chargers...they do almost nothing . they decide 2 voltages in time and the rest is done by physics. the mppt controllers simply do "perturbe and observe" to follow the Vmppt. which they found by scanning the IV curve of the panels , which they do again at regular intervals of a few minutes. This is only in the first phase. If the battery maintains one of the 2 voltage targets, apse or float, THERE IS NO MPPT!! Without understanding this you will never understand well how a control works and less than ever you will be able to judge it well or badly @@ProjectsinParadise808

Did you end up taking the cover off the faulty solar panel to see if there was anything obviously wrong ?

From what I can tell, the EPEVER problem is either a software bug or an issue with paralleling mulitple controllers. It seems to happen during shading events(clouds) and first light start up. It will just sit at 14v all day long till the string is reset. One comment on another one of your videos mentions having fixed the issue by adding a diode on the output of an EPEVER and that fixed it. It could be that simple. Victrons are great for the price but not perfect either. Definitely faster then the EPEVERs and possibly more reliable. I do like the EPEVER housing though. Remember to cover a panel string before you cycle it to test so you don't arch the string

Only just seen this. What you are seeing is a common fault with the Epever. Its search for maximum power gets confused, perhaps by a cloud, and locks on to the low voltage part of the panel volts/ current output curve. It may change if solar condiconitions vary, disconnecting and reconnecting the panels will often restore correct operation.

Stiamo facendo troppa confusione dando opinioni senza avere le basi per farlo. 1)You can't take the test with 2 regulators in parallel !!!! If one arrives at the battery with one thousandth or more voltage than the other, the other will give 0A. it is pure physics !!!. even if you have set it the same, it is enough 2 cm of difference in the length of the cables to distort everything. The test is only valid until one of the 2 can reach the target voltage of absorption or floating. ONLY IN THESE CASE EITHER CONTROLLERS ARE MPPT WORKING.(Topic in my answer to myself). after that the rest makes no sense. it's just to study the law of ohm to understand that what you see has nothing to do with tracing, speed, control and other things you said. IN ABSORPTION AND FLOATING PHASE, if the phase target voltage is manteined any control dont work MPPT. Because is simply non physically possible. And the current will only be divided according to resistance and voltage. When you see epever at 86v pv, 13.9v and 0.0A and victron at 13.99v and 10A, THE CONTROLLERS HAVE NOTHING TO DO!!! If the victron arrives on the battery at 13.99 and epever at 13.95. the law of ohms does not allow epever to provide power !! Raise the float voltage of the epever and you will see that it will be the victron to give 0.0A is the same thing as when you travel in a camper with a 13.8v float controller and a 400w load on. THE CONTROLLER PROVIDES 0W AND OA AND THE PANEL VOLTAGE RISES, AND ALL A LI PROVIDES THE ALTERNATOR BECAUSE AT 14.3V IT EXCEEDS THE CONTROLLER VOLTAGE. BUT if you raise the control voltage to 14.5v, he will be the one to provide everything and the alternator will provide 0.0A It is PURE PHISIC NOT CONTROLLER ENGINEERING 2)I WILL REMEMBER That in the absorption and maintenance phases, the controller DOES NOT WORK IN MPPT !! THE MAXIMUM POWER VOLTAGE IS NOT PURSUED, because, if the phase voltage target is reached, for purely physical reasons, maximum power is not required and therefore the controller CANNOT FORCE THE PANEL TO ITS MPP VOLTAGE. The mppt operation only resumes if a load powerful enough is turned on to exceed the maximum production of the panel, and thus absorb a part of the battery's current. In this case we return to the condition of the first charge phase, that is, in which the voltage cannot reach the phase target! Then the control returns to modulate the load resistance in such a way as to keep the panel at the ideal maximum power voltage (MPP)

Look how low your solar voltage is on the epever controller. Its letting in nothing because the panels are miffed. Its RIGHT THERE ON YOUR SCREEN! You clearly have a bad connection or panel or something else going on. Thats the ONLY way to explain the voltage being at 86 unloaded and 14 under load. Stop blaming the controller. It may be inferior to Victron but IT IS NOT YOUR ISSUE TODAY just like the other controller wasnt your issue yesterday =)
