    If accurate this spec would equal a no buy from me:
    Max. Solar Input Voltage : 25V

    • AssociatedJudy Yan @ Renogy on 18/02/2021 - 15:15

      The DCDC50S with MPPT's output depends on what power source is available. If both solar and starter is available, then the maximum output for each is 25A, total of 50A. However, if starter for example is not present, the solar will now have a maximum output of 50A and vice versa.

        My comment is about it's input voltage from solar.

        You've talked about its output current…

          Hi，
          We are so sorry for the wrong reply.
          This is the manual for this product:https://au.renogy.com/content/manual/battery%20chargers/RBC30D1S-RBC50D1S-Manual.pdf
          Max. Solar Input Voltage:25V

    • AMLagonda on 18/02/2021 - 15:57

      What do you mean "overcoat"? 25volts???

      Ctek has a limit of 23 volts and 25 amps

      • tunzafun001 on 18/02/2021 - 16:16

        I suspect 'overcoat" means overload.

        Got anything with a larger throughput Op?

        I Want to setup a charging system with old roof solar panels. They are 44v.. each panel and I'm looking at around 5 panels for a 1400w throughput.

        My car has a 2500/5000w inverter and can happily handle 200 Amps.

        I guess once you step down from say 220v you increase the amperage and need larger, more expensive components/ cabling.

        Could you run a few of these in series?

        • virtual81 on 19/02/2021 - 09:23

          overcoat is the name of the first commenter.

      • virtual81 on 19/02/2021 - 09:23

        In that case i wouldn't buy the Ctek either.
        Victron energys rang of solar controller start at 75v input as the max and that's just the basic models.
        A limit of 30V or less excludes the ability to use common 180W - 350W panels.
        Not uncommon for these to have an open circuit voltage in the 30-40v range.

    • stumo on 18/02/2021 - 16:11

      Yeah for an MPPT, 25V is stupidly low. Thats PWM from a 12V panel territory. My MPPT solar charger allows 100V, so you can make the most of your panels by running in series. An array of parallel 12V panels @50A is crazy.

      • Lolitsjoel on 18/02/2021 - 17:28

        Redarc's BCDC's do 32VDC max.
        Enerdrive's 40A DCDC do 45V max.

        This is a DCDC with built in MPPT. Go a Victron only unit if you need higher V.

        25v is pretty reasonable for 1) the price 2) what the unit actually is

        • ob123 on 18/02/2021 - 20:30
          +1

          Yup if you want to run 45V (House panels) you’ll need the Enerdrive for double the cost and a larger footprint.
          Or you can save your dollars and get solar panel to suit. Nothing wrong with Renogy kit they are great bang for buck.

        • virtual81 on 19/02/2021 - 09:38

          At 30v at least you can get in to the realm of running 250W household solar panels, readily available and commonly found with a 28 - 30 v OC spec.
          At the 25v this product specifies these kinds of readily available panels are out of the question.

          Using 18vOC rated panels (so called 12v panels) is old fashioned and inefficient.

          As mentioned elsewhere, high vOC panels combined with a good MPPT reg can start charging earlier in the morning, harvest more power when in lesser ideal conditions and and will run until later in the evening.

          Common MPPTs require that panels need to provide 5 volts more than battery voltage to begin/resume charging.
          This is easier achieved with higher voltage panels.

    • virtual81 on 19/02/2021 - 09:19

      25V PV input voltage limit - yep no buy.
      That's pretty limiting.

  • Lead Wings on 18/02/2021 - 16:11

    12V solar panels are normally around 18V, so 25V should be good. Home solar panels are more like 37V.

    Issue I have with this is the Smart Alternator (Euro 6): 12-16VDC. So I have a camper trailer and modern Prado, and a 25A DC-DC. Even with 6 AWG cable (ie bloody big) the DC-DC can see as low as 10-11 V. So this would be no good for that application.

    Should be OK for under the bonned dual battery applications.

  • debjy on 18/02/2021 - 16:11

    Am I right in saying the specs on this look better than the Kick Ass model?
    https://www.australiandirect.com.au/buy/kickass-dcdc-mppt-so…

    THe Kick Ass is water proof though.. IS this one?

    • AssociatedJudy Yan @ Renogy on 18/02/2021 - 16:18

      Hi, Renogy 50A DC-DC Battery Charger is not waterproof.
      We have other voyager 20A PWM waterproof Solar Charge Controller.

    • DonWilson on 18/02/2021 - 21:57

      The Kick Ass might be better. Maybe.

      The maximum output there is 25A/368W, which seems pretty low. So even if you max out the input with the 1,000W+ allowable it'll still only output 25A, < 368W most of the time, around 335W most of the time if charging lithium for example.

      With the Renogy… honestly it's unclear what the combined maximum output amps/watts are. They don't appear in the specs and the manual only reallys talks about the inputs. There's a 65A fuse on the output so maybe the full 50A. But the 50A clearly refers to the combined maximum inputs, and the inputs are fused at 75A. If the fuses are proportional that means a 43A/635W max output but there's no reason to assume they are proportional. I'm going to go look if anyone's tested it.

      • DonWilson on 18/02/2021 - 22:04

        I'm probably being a bit overly skeptical about the phrase "charging current". It probably means the output which would mean basically double the output of the Kick Ass. But the input maximum also being 25A+25A makes me with they'd just use output current instead of charging current in the language.

  • AMLagonda on 18/02/2021 - 16:24

    My mind is boggling, why would anyone put more than 25 volts in a dc-dc charger?

    even Really expensive Redarc maximum voltage is 32 volts

    • overcoat on 18/02/2021 - 17:14

      As stumo said above, if you have more than one "12V nominal" panel you can run them in series rather than parallel which would be required with this low input voltage spec.

      In series the voltage is higher and current is lower. That means you need a smaller cable diameter (which is cheaper) and get less voltage drop over long runs.

      Also the startup voltage for the MPPT is likely to be achieved earlier in the morning.

      • virtual81 on 19/02/2021 - 09:27

        I'll add to that and say that larger house style solar panels usually start at 28vOC and go higher from there.
        It's 2021 and MPPT controllers are being designed to accommodate these ubiquitous pannels, this device and any other with such a restrictive PV voltage limitation is not ideal, not comparable to any other half decent MPPT controller.

  • AssociatedJudy Yan @ Renogy on 18/02/2021 - 16:30

    The DCDC50S with MPPT's output depends on what power source is available. If both solar and starter is available, then the maximum output for each is 25A, total of 50A. However, if starter for example is not present, the solar will now have a maximum output of 50A and vice versa.

    Judy looking around at options at the moment.. Can you do anything on the price of the Renogy 100 Watt 12 Volt Extremely Flexible panels and Bluetooth module?
    Are there still firmware issues on the Bluetooth module?

        Bizarrely I bought these panels for 159 about a year ago on the renogy au website so it's not the lowest possible price. On the other hand would buy them again in an instant! Have not much experience with other panels but the fact that they are flexible works like a charm on the roof of my pop up camper which has a slight curve. Make sure to put some corflute underneath for airflow!

        • debjy on 19/02/2021 - 00:09

          Did you just use a bunnings corflute? What adhesive did you use?

          • Mikez026 on 19/02/2021 - 10:14
            +1

            @debjy: Bunnings corflute and cut to size in 2 layers(one horizontal one vertical) then roughed it up with sandpaper and used a plastic adhesive to stick the 2 layers together and might have used a dab of sika 11fc on the corners. Then used metal square washers(large cut in (so it's flush) the bottom layer and siliconed in to put the bolts through them and fix the panels on. The metal is important as the corflute adhesion to the roof of the camper alone wasn't to be trusted, discoverer thay in my first attempt. Then clean the roof thoroughly and light sand it to stick the whole assembly on the roof with sika 11fc. Finish off by bolting the panels on with double sided tape as am extra. Ideally you would have at least the corners bolted through the roof for extra safety but that wasn't possible in my setup so I also have additional ankering just in case just with a metal wire so if they come loose they don't fly off the roof. But to be honest the metal connection points are solid as anything stuck on with the sika 11fc. The corflute has come loose though on the edges where between to roof of the van but that could be because of the curve together with heat in summer, the middle is still solid.
