    Thanks for the great video! I just finished installing the RSP-750-15 in our Sprinter. The days here in Vancouver are getting shorter, and it took us almost a week of collecting solar to recover back to 100% battery from a 4 day trip we took. It's going to be nice to have the option to grid charge if we need to bring our battery back up faster. "When you need it, you need it!"

    Thank you for an awesome video! I've already got a RSP-750-15 that we use for charging a small lithium battery. However as it was slightly too vigorous for our smaller battery we had to turn on all of our loads to reduce the amount of charge going into the battery. However now that I've added the 10k potentiometer as per your video I've adjusted it down to 40A charge rate. I cut the jumper wire between pins 7 & 8 and soldered to those. However the ground pins 10 & 11 had nothing in the plug to ground too. Fortunately in the manual it mentions that the ground pins are connected to the -V terminal. So I confirmed it with my multimeter and then crimped a ring terminal onto the ground wire and attached it to the battery negative terminal. Works a treat! Thanks again :)

    Fun stuff! We were looking for a cheap way to charge our 24 V LiFePO4 batteries and came across meanwell too. It's actually quite hard to find a power supply offering 27V with current limit. I read about certain versions of meanwell PSU that you can hack to alter the output voltage. Eventually i found out that meanwell offers a whole series of chargers under their ENC line. These come with preset charge profiles for most of the battery chemicals (lead flow/agm/etc) but also allow you to program your own profiles. They also come at a pretty reasonable price. Only downside might be that they only offer up to 360 W (but I guess you could also just get more than one).
    We chose the 240 W model and it's outputting full value at 8 A. Doesn't sound much but it charges our battery in a day. Under normal use (lights, fan, laptops) 240 W is plenty enough. Even for running our water heater it's not bad at all. It takes 3 hours to charge back what the heater needed.
    So if you don't want to invest a lot of time in setting up a regular PSU I think the ENC series is worth a look.

    Great video! I use Meanwell quite a lot, they are at least as reliable as a 'known' brand charger. While not so know in the RV world, but in the industrial world (PLC, automation, led drivers) they are among the top 5 of most used/best rated power supply manufacturers.
    And they are cheap, especially if you find overstock. While the RSP is not a charger, but a power supply with CC limiting, it works great as a charger. It's only not stopping charge, but provides a continous voltage. With the SBBM this is a clever way to overcome this.
    I only would set the voltage to 14.4 or so. Still provides (almost) the same full amps, but if for some reason the SBBM is not switching properly, you still remain within the 3.65V / cell limit of the pack (while 15V would overcharge at least 1 cell for sure)

    • @Everlanders
      @Everlanders  2 ปีที่แล้ว +1

      Great Comment and good points. I could turn down the voltage as you say, it couldn't hurt anything, but it's the same SBMS controlling 100-amps of solar, so if it fails, they would get charged up to 20-volts anyway.

    It just occurred to me, you could wire up the power supply's current control remotely to your system, and then adjust the amps pulled based on time of day. Maybe set it up where at night , when hopefully no one is using power, you pull more than during the day, when people use it the most, or vice a versa.

    @junkerzn7312 ปีที่แล้ว +1

    That meanwell is a fairly high-end power supply. From the schematic, the output is isolated so theoretically it can handle being connected to the battery even when turned off. But it doesn't explicitly say that it can so it is important to make sure that actually works without anything taking damage or causing other problems. (Most power supplies not explicitly flagged as battery chargers actually short-out the output, aka the battery in this case, when turned off or disconnected from their power source).
    Other than that, you selected a very nice power supply. Its has PFC circuitry (which basically means it doesn't jerk the AC side around like a regular rectifier would), and it averages 89% efficiency.

I mistakenly turned off the unit whilst charging a 305ah cell and luckily returned to some smoke and not a fire. The capacitor seemed to take the brunt of the backfeed and spilled its contents ..

    I use a meanwell on my RV, it is a 13.8v 50A unit and all of my solar controllers, and alternator charger is 13.8v on our lifepo4 setup. the battery will fully charge to 13.8v off any system and the power supply starts at 50A then slowly tapers down as the batteries come closer to 13.8v where I found that a CC/CV controller runs it fully to 13.8V at full amperage before shutting off and transitioning to CV. so with the controller you can get a better charge rates above 80% of charge (in regards to charge goal, not SOC) I do like the trigger control though!
    one idea, don't use a Pot, but measure some resistors, solder to a rotary switch, and set it for something like 3A, 5A, 10A (or max) from the grid, so you can just set it to what the grid can offer rather than having to do the math each time.

    Someone probably already suggested this considering this video is over a year old but I see that the truck you're driving is a diesel or gas-powered. They make an alternator specifically to charge your batteries as well as performing its regular duties. So you would wire it up to go towards your batteries and every time you ran the truck it would charge your batteries. These alternators are super powerful and can probably charge your entire battery with just 45 minutes of runtime.

    • @Everlanders
      @Everlanders  ปีที่แล้ว +1

      Unfortunately not true in our case, charging 11.5 Kw of Lithium from an engine alternator would take 10 to 12 hours assuming the alternator could tolerate a 100 amp load for that long. Secondly, we drive about 20 hours a month... Furthermore, Converting Diesel to Electricity (assuming an engine efficiency of 40%, a belt efficiency of 98%, and an alternator efficiency of 55%) leads to an overall energy conversion efficiency of only 21%. Assuming a fuel cost of $4.00/gal, this leads to an on-board electrical power cost of $0.51/kWh = $5.86 in fuel costs per charge.
      For that reason, we have not had our alternator connected since Northern Mexico, Early in 2019 - We get all our electrical power from Solar. And while you are commenting on a video about the Grid Charger, We have used it twice since this video, and even then it was an unneeded luxury.

    Great video. I now understand how the 750 works thanks to you. Very limited info on the 750. I really like your idea of adding a potentiometer to regulate the amps. Great idea. Where did you order the cn50 connector and what was the p/n if you don’t mind. I like that idea for another purpose. My plan was to control the 750 with the Dext16 and a resistor but I like your plan of using the ext 105 plan better. Thanks for the great video. I now have a better understanding of the rsp-750. Going to try again to see if I can get the unit to run or wait till Dec 2022 for new inventory.

    You connect the output of the power supply together with the output of your solar panels. If I have an MPPT solar charger, could I just connect a power supply with high enough voltage to the solar input of my MPPT charger and charge that way from the grid? My MPPT charger can take up to 100 Volts input, is a higher voltage output of the power supply better?

    • @Everlanders

      Not Exactly, the output of the charger is effectively connected to the battery, just through a shunt to measure the current. (and it's the same shunt that the output of the DSSR20 chargers are connected to.)
      I suppose connecting a power supply to a dedicated MPPT could work... I've never tested this.

    Hey! When you run into outlets with reverse polarity do you walk away or use a homemade pigtail cord or something to correct the hot and neutral polarity (I assume you don’t want to feed the Meanwell reversed polarity input?)? Also, does your Meanwell tolerate an open ground input connection or do you have to use something like an adapter to create a false ground connection from the neutral?

    If SBMS poops itself, how many systems go down and what redundancy do you have for that.
    No heat transfer tape / goo on the back of the AC charger?

      No, At $2/kWh to charge from the alternator, it would be silly to convert Diesel to Charged Batteries when we have so much solar... In fact we have our alternator's control wire disconnected and power the Engine's electronics from our Solar and Lithium. Furthermore, even if I pulled 50 amps from the alternator, it would still take 20 hours of driving (and $22 in Diesel) to charge it completely.
      If the SBMS were to fail, everything would continue to run fine, I would need to manually trigger the DSSR20's to charge every few days. If they ALSO failed, I could connect them to the battery directly because they can only harvest a maximum of 7kWh per day... so I'd just wait until the 11.5kW battery was at 30% or so and then let it charge... But, We already have a spare SBMS60 and SBMS100 that we got before leaving on this trip, so I could just connect one of those. ALSO... don't forget that the SBMS is open source and I've burnt them up and fixed them on the side of the road before: th-cam.com/video/7RdbXw5mJsA/w-d-xo.html
      No thermal compound or pads... It's pretty efficient, doesn't get that hot and like I've said, I hope to not use it that often, In a little over a year since we've had it, We've used it twice...

      In the planning phases I considered it, but when you consider that extracting electricity from diesel costs nearly $2 per kilowatt hour. It would cost $22 and 20 hours of driving to completely charge our 11.5 kilowatt hour battery bank. It's not free energy... not to mention the added cost of alternators, brackets, DC to DC charge converter... We elected instead for more solar panels... In fact we haven't used our alternator since 2019 in Arizona someplace, rather, we power the Engine and Charge the Chassis Batteries from solar exclusively.

    I didn't catch what kind of batteries you have. I am going to assume LiFePO4. LiFePO4 is a bit different from normal lithium-ion in several ways, and one of them is with the BMS's SOC tracking. The other is that when cycled regularly, LiFePO4 batteries can be charged to 100% without taking any damage.
    LiFePO4 batteries should periodically be charged to 100% (3.55V/cell = 14.2V at a minimum) and held there for 2 hours or so in order to allow the battery's BMS to balance the cells and reset its SOC. The BMS won't balance the cells at lower voltages. BMS's will lose track of the actual SOC when the battery is not charged to full due to the discharge curve of the LiFePO4 battery being so flat. Unfortunately, some BMS's require charging all the way to 3.65V (14.6V) before they will actually reset the SOC tracking to 100%.
    So if cycling the battery regularly, 100% SOC is generally more reliable for LiFePO4 batteries. If you use 80% as a target, you may notice significant SOC drift, sometimes to the point where the battery is not actually getting charged much.

Then you can build on the example while still having the instant gratification of incremental successes.

      While using a diesel vehicle's engine alternator to generate electricity seems intriguing, the efficiency calculations unveil a less-than-optimal reality. While diesel is recognized for its high energy density, the process of converting it into electricity introduces complexities affecting overall efficiency.
      1: Energy Density of Diesel:
      Diesel has an energy density of 45.5 megajoules per kilogram, theoretically yielding 14 kilowatt-hours of electricity per kilogram.
      2: Engine Efficiency:
      Assuming a relatively generous engine efficiency of 40%, this percentage represents the conversion of diesel fuel's energy into mechanical energy.
      3: Belt and Alternator Efficiency:
      To transform mechanical energy into electricity, we consider the vehicle alternator efficiency at 55% and the belt efficiency at 98%. These values encompass the efficiency of the entire mechanical-to-electrical conversion process.
      4: Overall Energy Conversion Efficiency:
      Multiplying these efficiencies, we arrive at an overall energy conversion efficiency of 21%, highlighting the inherent losses in the system.
      5: Calculating the Cost (X):
      To understand the economic implications, we calculate the cost (X) of charging an 11.5 kWh LiFePo4 battery bank:
      X=(11.5kWh/0.21)×Diesel price per kWh
      Substituting the values, we find that X is approximately $59.71 which is the total cost to charge our 11.5 kWh LiFePo4 battery bank or $5.18 per kilowatt-hour.
      This figure provides insight into the economic efficiency of the diesel-to-electricity conversion process. The overall energy conversion efficiency of 21% suggests a significant portion of diesel's energy potential is lost in the conversion process.
