    Gday from Australia. Would you know whether 'boost' charge is the same as 'bulk' charge? My boost charge is set to 14.4v, and float is set to 13.6v. On the manufacturer's website, there is mention of bulk, absorption and float charge, but no boost. I am confused because I thought that the batteries would not need a time limit for bulk charging,. It then again I am not very experienced in the area!
    p.s - I have 2 220ah 'pure energy' agm batteries in parallel, 4x 160w panels and a 60a charge controller.

      Boost = Absorb = Topping Charge, basically different names for the same stage:
      chargetek.com/basic-information.html
      I usually keep my boost time at the default and it seems to work OK.

      Im having an odd problem with my controller now, you may have experienced this problem before, or have some insight. My batteries have been feeling like they are a bit flat lately, which is what prompted me to look into the settings. Turns out that when the controller begins bulk charging, the voltage has been spiking above 15v 30a for a very short period, which then triggers the over voltage disconnect. I've tried lowering the charge limit, raising the voltage disconnect, and just tweaked a few other settings, but keep arriving at the same outcome. It triggers over voltage then goes back to 12.9v 0.5a for a minute, works it's way up, then the cycle repeats. I've sent an email to the manufacturer, will be interesting to see what they say. The batteries are under a year old and have always been together in parallel, never discharged below 12.2v

    Wow! Thank you for your speedy reply. The batteries are now at 12.85. I have had the charger on for about an hour. No blinking light on the controller but its says 3.2 from the PV's to batteries on the MT50? No PV green light. Its off.

      Not sure on the 3.2, is that volts or amps? Sure sounds like the charge controller is messed up somehow. Maybe there's a way to do a factory reset, I've seen that in the MT-50 menu someplace.

    • @The4Crawler
      @The4Crawler  4 года назад

      It's likely that the controller is seeing the battery voltage is too high (Over Voltage Disconnect) for what it's currently set to. Either discharge the current pack to 26-28 volts and see if the controller will recognize it and go to the 24V setting. Or hook up a pair of 12V lead acid batteries in series temporarily to use to power the controller. Then enter your user parameters for the 7S pack and switch to that setting before disconnecting it and reconnecting to the 7S pack.

    Hi we have an Epever in our caravan - no MT50 or cable to connect to PC. Our lights have started going out at weird times and the water pump - all 12 volt power - Main is fine. Could this be a Timer issue and how do we adjust it please.

    • @The4Crawler

      Likely the built-in load timer. Look up in your unit's user manual for the procedure for setting the timer (might be called "load work mode"). That will vary from unit to unit. On my older unit, that is mode 17, which is always on or off controlled manually by the load button (on the right of the controller). The other modes are combinations of on and dusk or dawn and off so many hours later (mainly used for street lighting).

    • @The4Crawler
      @The4Crawler  4 года назад +1

      Glad you found the issue. I had a batch of 5 solar panels I bought a while back and every one of those had flaky MC4 connectors. They all started out fine but one by one they would go bad. But they were hard to find as a voltage check would read fine. Likewise, if I stuck meter probes into the ends of the connectors and did a short circuit test, again normal readings. But plug that bad MC4 into a good MC4 and then very little current would flow, like a few hundred mill-amps. I think I've finally got all the bad connectors replaced.

      @The4Crawler  4 года назад +1

      @@TheBirdandEagle Yes, at least the MC4s that come on many panels seem to be garbage. All the ones I've replaced are holding up much longer. Part of the issue is there seems to be minor variations between one mfg. and another in the MC4 fit. I found the failed connectors had slightly shorter center terminals and just barely fit into the connectors on my cables. But if I changed out the connectors on the panels with the same connectors I used on the cables I built, they all fit much better.
      The problem is there's no easy way to tell what style MC4 was used on the panel so that a well fitting one can be used on the cable you connect to it. So it's just easier to chop off what's there and replace it with the same connector used on the connecting cable. I guess those are a type of things that an outfit that does solar installs every day would have sorted out, but us mere mortals have to learn the hard way.

      Without a load terminal, your load will need to connect right to the battery bank. You could install a meter something like the PZEM-051:
      amzn.to/2NZSDJH
      In series with the load and it'll record power flowing from the battery to the load.

Like you said before I have to connect the load directly to the battery bank. I bought a dc power meter (100A). Thanks for the advice. Regards

    • @The4Crawler
      @The4Crawler  5 лет назад +1

      Yes, that may be the case. Both 40A Tracer charge controllers I have only support 20A of DC output. One option you can do with a controller like that is use the DC output to turn a high current relay on and off. That way, you can set the controller's low disconnect voltage to a particular value and have it turn the DC load relay off if the battery is discharged too far. But you would need an external meter for that to measure power.

      That typically is a crude state of charge display. I think there are 3 or 4 segments of that icon, if all are black, full charge, if one is black ~25% charge. This is not accurate at all as there's no separate battery voltage sensing leads and no way to calibrate the state of charge to the voltage read inside the controller.

      ruclips.net/video/jUQOF7qrKLE/видео.html
      Same parameters can be used on the MT50. Should be able to connect the controller to a battery and a computer to run the setup program (Windows or Android). When I connected mine, I used a long Ethernet cable from the controller into the house then plugged in the RS485-USB cable which was connected to my PC. I believe the controllers save those parameters in non-volatile memory, although I've never tested that feature myself.

      It probably won't hurt to set it lower. I'm not sure what affect that parameter has on the controller. I suspect it might affect the transition to float charging, such as if the current reaches 0.01C or some figure like that. So a 200AH battery would need to drop to 2 amps charging, while your 65AH battery might be 0.65 amps. That said, I've tried close to correct numbers and higher than actual numbers for the AH setting and I don't see any noticeable differences in charging.

      Start by disconnecting everything and then start reconnecting first the battery and make sure the controller works that way and reads the voltage correctly. Then connect the PV and check that that's all OK. If the battery is fully charged, you may need to discharge it a bit to get the controller to start charging. If you have a DC ammeter, connect it in series (or clamp the probe around a PV wire) with the solar panels and see if there's any current flowing. You can also use that to test the solar panels separated from the controller, check the short circuit current and make sure it's close to the panel rating in full sun. If all that fails, it may be a bad charge controller. If new, contact the seller or tech support with the mfg. and see if they have any other suggestions.

      I find I often have to go through the MT50 user battery settings a few times to get the complete change entered. Why? Because there are settings later in the menu that can affect/limit earlier settings. If you have the Solar Station Monitor program, you can see all the settings at once. But in the MT50 display, cycle through the settings and see if there is any of the later settings that are set to 14.4 and bump those up, save the setting then re-enter the settings menu and change the earlier one.
      Not totally sure on the boost charge cycle. According the the manual. that setting is the time it remains in the constant voltage boost charge stage before switching to float.

Unless I could see the disc of the sun through the haze, there was almost 0 charging going on. Might also try disconnecting and reconnecting the solar panels.

      @N2Stooges 4 года назад +1

      Equalization time setting control how long the charge controller will set the voltage to the battery at the equalization voltage (which is normally set to be slightly higher than the boost voltage setting). On my Tracer 4210A MPPT charge controller, an equalization cycle is only performed once per month on the 28th of the month and the interval between equalizations is not adjustable. An equalization cycle is a deliberate overcharge of the battery and is used to condition lead-acid batteries to help remove sulfate crystals that build up on the battery plates over time thus extending their lifetime.

I only used my 35AH AGM batteries on my older c/c and it didn't have a user battery type, so I set it to Gel and then once every month or so switched to Sealed for a day to get an EQ charge:

    Hello!Hope someone help me with this.I`ve just set up my electrical system.Renogy solar pannel
    160W with 20A MPPT Epever charge controller with Victron 125Ah SuperCycle leisure battery.When i got my leisure battery delivered i dry test fited everything to make sure its all good.My first question is:Why the MT50 remote meter shows my battery is fully charge (14.1V) with the "smiley face",but the actual load in the battery is just 11.7V (just received and still did not make the first 24 hours charging).The seccond question is even if a put a load i can not see the AMPS in and out on the remote meter,it shows just 0.00 i guess this is because if i dont put load via solar charge controller outputs i am not going to see the amps flow on the MT50,am i right for this or not?If so i guess i have to install a separate "battery meter" where i can get the correct load and condition on the battery.Also there is a option "Charging energy history" u can check daily and monthly how much power you getting,but after 4 days mine still shows 0 on everything,thanks in advance

    • @The4Crawler
      @The4Crawler  4 года назад +1

      You'll only see the Load amps and energy history if you connect your load the the DC load output of the charge controller. I don't believe the meter will record charging history, only the DC load history. You can hook up your DC loads like I did in my shed:
      ruclips.net/video/DAPstiLMGUA/видео.html
      Not sure on your battery voltage issue. It may be that the battery voltage is below the charge controller low voltage cut-off point. Maybe try charging it up to something over 12 volts and see if that helps. If a brand new battery is at 11.7 volts, something may be wrong with the battery. Connect the battery first, then the solar panel then the load.

    It sure would be super if someone would make a video actually explaining in detail what each of these charge controller settings do rather than glossing over them. There are plenty of videos on how to use an MT50 control panel to change the charge controller settings but none that I have found that explain ALL the settings themselves IN DETAIL. Even people who sell these things don't know how all the setting work. Crazy huh?
    I have a Tracer 4210A charge controller with MT50 currently in use with SLA batteries but am interested in knowing if this charge controller can be safely used with Bioenno LiFePO4 batteries by using the "User" profile setting of this charge controller. There is no clear information for suitable charge controller settings for this configuration. Bioenno wants to sell you a different charge controller that is "LiFePO4 compatible" but what about my Tracer isn't compatible? LiFePO4 batteries expect a constant current (CC) bulk charge followed by a constant voltage (CV) boost charge. The charge controller when in bulk charging phase is essentially current limited by the size of my solar array (100W) so it seems like setting the "Boost Charge" voltage and "Float Charge" voltage to somewhere between 14.4V and 14.6V should suffice. Equalization time would be set to zero to disable equalization cycles. Solar panel capacity would need to be sized so that the maximum charge current available during bulk charge cycle would be less than the maximum battery charging current spec. For 30Ah Bioenno battery, the specified charging current is 6A (I assume that is a max spec) thus a 6/30 (0.2) charge rate max. With my current SLA battery setup, I have never seen the charge controller push more than 5A of charging current. I think I am safe using this charge controller with the 30Ah LiFePO4 battery or am I missing something here?
    Thanks for the helpful video.

    • @The4Crawler

      I go into some detail on Li-Ion settings with these controllers starting in this video:
      ruclips.net/video/jUQOF7qrKLE/видео.html
      Basic idea is to pick the volts/cell you want to use for the various charging states and then multiply by the number of cells in series and that's the user voltages you enter into the controller. Then some tweaking of the numbers is needed taking into account the controller's 0.1 volt increments, no voltage sensing ability and also if you have any external loads that are sensitive to the actual voltage. For example if you have an inverter that can't go above X volts or a BMS that needs to see Y volts, etc.
      And yes, I pretty much set all the voltages near the same, "float" being maybe 0.1 volt below "boost".

    Thank you so much for this RUclips! I am not your typical Subscriber or Viewer as I am not nearly as technical. I have owned an MT50 & Tracer4215BN for two weeks (Amazon) and am trying to figure out if one or both are defective (before my 30-day return is up) or if I just can not figure them out. You just solved one big problem for me!
    My first Problem:
    (I was unable to get the "Sealed" parameters to change so that I could match them to my batterie's Owner's Manual (1200Ahour 12 Volt AGM X 4).
    My second problem:
    My panels ( 4 X 100 watt, 12 Volt, paired parallel with each pair in series) charge my batteries per the "Sealed" parameters each day. The battery icon shows fully charged by 2:00PM and the Charge Controller goes into "Float" which is 13.8volts. Once the sun sets and the panels stop producing enough for the charging to continue, the green "PV" light goes out on my charge controller (which I think is "normal"). BUT, then over a very short period of time like less than an hour, the battery Icon diminishes in "bars" down to as little as one to two bars. My calibrated Fluke DVOM tells me the batteries are at 13.2 Static charge and so the icon should show full. It does not. I recheck in the morning after a cool or hot night and the semi-resting voltage is 13.1x but the battery icon remains at or near the minimum. We the sun comes up it does not change. The charge cycle starts all over again and before noon (if I did not use the batteries that night) the icon indicates "full" (all black bars) and the charge controller goes back to "float" of 13.8volts. What is wrong with my system that the battery icon does not match the actual battery charge after the panels are disconnected from the batteries by the charge controller???

    • @The4Crawler

      If you want an accurate SOC reading, get something like a Trimetric Battery Monitor:
      ruclips.net/video/5LcY-EqOV5Y/видео.html
      These type of meters measure amp hours in and out of the battery and use that to determine SOC instead of some mystery battery voltage reading. If at least they had an external voltage sensing connection to the actual battery bank it might do better.

      Like your second link, I do have a shunt on the load side of my battery bank going to my 12VDC -120VoltAC inverter and I monitor total Ahours consumed by combined loads with a sufficient and conservative margin to protect my battery bank. I just manually take note of amphours consumed and always disconnect the load if it gets near 20% of total bank amphours consumed.

      Yes, it sounds like your SOC display is working like all the other EpSolar/EpEver displays. When I got my first controller with the MT-5 remote, it had the same SOC indication and at first I would panic each time it dipped down to one bar. But a check with the volt meter and it was normal. I later added the Trimetric and used that instead. But yet, AH-in vs. AH-out is the best way to handle SOC.
      It's kind of like those pressure gauges on propane tanks that have lever readings like empty and full on them. Those will read full up until the last few minutes of gas in the tank then they drop to empty. What you really need is a liquid level reading inside the tank.

It is possible to set charging voltage to 16.8v but when you enter overvoltage reconnect to 17.1 its error and when you move on next settings it says 12 or 24 or auto system voltage.

      A few things to consider. One is that 17V is the maximum on any of the settings. Not sure if that means 17.0 or maybe even 16.9. I've only used up to 16.8 when I was setting up my 4S battery. The other issue is that there are some settings that other settings have to be at or below. I found it took a few cycles through the menu screens on the MT50 to bump everything up. I think I mention that in the video, that being there's a setting later in the USER menus that affects a setting earlier.
