 Hey there YouTube, I thought I'd just share this little project and what I've done here is I've wanted to be able to use the power from my batteries from the solar panel a little bit more efficiently. Don't get me wrong, that little power supply there that gives me, you know, it's a linear regulated so it gives me pretty much up to the battery power minus a couple of volts which is okay, you know, when you're doing the little things, but I once went with a little bit more rump and as my power supply broke I decided to use some modular units and just put it together and I've come up with this. So what we have is a, at the minute it's running from this little power supply which is powered by that ATX box there and I'm just giving it round about what my, what the batteries would be. So if we say sort of like 12.8, 12.9, of course that will drop a little bit eventually and so it's sort of simulating what I'd normally have on the batteries anyway. So it's really dull day today and I used a lot of battery last night so I'd have got 12.7. So what I've done here is I'll put a boost converter in here but the boost converter can go up to 84 volts and the input on this can only go up to 60 volts because this will give me 50 volts on the output. Up to 15 amps it says 750 watts but I don't think it's got the heat dissipation for that but no one's. I'll try and be doing a test on that today just yet. So what we got here, this is a little bit bright for me at the minute so I'll just quick this up. So you can see we've got 15.1 volts, that's not what's coming in, what's coming in is yeah, your 12.2 there it says and we've got 15.1 here now and I can turn this up. And this gets me to my maximum threshold of what I can put into here but it will go further so I have to ensure that I don't turn this up and I certainly don't flip this switch into the on position while this is on 82 volts. This is one of the reasons why I put this control here was if I was going to have like again on 60 volts input into there permanently for lots of reasons so if I'm really going to be using let's say 20 volts out of here you know I can put this up to 25 volts or something at 1.1 ratio isn't it really and that can go in. So I can leave this on let's say let's just say 15.5, 16 volts, then I can switch this on and this is the DPS so it's the new version of the DP by ID Tech. I'm not going to go over all the controls of this but as you can see down here we've got a voltage input and it says 15.92, 15.7 and here we've got our output values which there's nothing up at the minute but if I switch this to the on position here I'll now have 9.3 volts on the output here. It's limited at the minute to 300 milliamp which is what I like I like the to current limit and I've also limited this whole thing to 250 watts max which is the maximum which my charge controller can provide it anyway. It's probably not the best of setups just because there is this problem here this was twiddled around all the way to the right that would pop this and it just kills off the whole thing but as it said it's going to be playing with it and I will never switch this on until I've switched this on and checked the voltage here. I'm not going to be too worried. So let's take a look inside seeing if it's a bit of a slap happy mix mash of whatever but this booster is one of the two boosters I got where the current adjusts didn't work and so I've got refunds on both of them so I just have to use one. I have it's basically just strapped in here as holes are drilled into the case and I strapped this in but it's a pretty good tight fit. This is held down. This is the board that comes with this this 50 volt 15 amp jubby it doesn't look like it's got plenty for heat dissipation but I don't intend on ever using that amount of power really. I just noticed that these wires here look a bit trumpy but and that's it so I've just brought my power in I've brought it to a switch and from that switch I can put the power into the boost converter that then comes through this voltage amp meter which is only 10 amps so I've got to be careful I do there I've actually got another meter that I may put in here which is coming which will go to 100 amps and it's got a milliamp there but I don't think it's really necessary for this it's only to give me a glide on what's actually what's actually gonna go in to this unit here so we come out up here into this double pole switch so I can turn off the negative and positive sides completely isolating this circuitry from here and then it just goes into here and then the rest is just controlled by this this little unit I don't know how steady this is or precise this is over a period of time because I only got it in yesterday and then I just spent my evening putting it into this I've learned lessons I learned lessons like maybe I should measure things out properly because then I might have a little bit more of a symmetrical gap between this and this and this may have just fit in a slightly bit better into this gap but hey ho these are all things that you get to learn while you're doing things and you know I'm not gonna try and say that I'm the greatest DIYer about because I'm not it gives me a practical and I just switched that off nothing really changes there apart from I'm not putting so much power anymore I switched that off there and that's it that's it pretty much isolated my little variable power supply just trying to use I wanted to use one of these and I wanted to use my batteries as well I like using the solar batteries because it just means every day that we get sunshine it's a it's a it's a positive it's a bonus always got power going into those batteries and I can always tap off them and the way I'm gonna connect this up at the back is so basically there's no battery power I'm gonna have a connector on the back so I can just go straight into power from there if necessary hmm so I just thought I'd share that some little thing I've been playing around with and I shall see you again soon. Cheers for watching!
