How much battery capacity do you have to be able to charge at 36kw! And what supplies that on the AC side, grid? I like the look of that rack, looks like it might also leave a small gap between the chargers, possibly a good idea if your running multiples for heat dissipation. I think some form...

Just a little update, upgraded my generator to a 3 cyl Kubota 7kw unit salvaged from an ex army lighting tower. Gave it a good cleanup and service and build an autostart control panel for it. Figured I might aswell make use of the increased power output and get a second AC charger from the...

Has anyone experienced a vibration/buzzing from (I think) the small coil winding within the Multiplus II? I don't recall it making this noise before, and it's very sensitive to just tapping even the outer casing of the unit slightly. And no it's not the main transformer making the nose! All...

Shh, we don't talk about the chit chat section around these parts.. it'll scare away the new members ?

Many times I've also expanded to the "engineer's floor" when the bench just doesn't quite cut it, same concept, just harder to navigate ?

Victron and Renogy should never be used in any sort of close comparison, there is quite literally, a difference of night and day. One is decades of engineering and constant monitoring and updating, and one is relabeled AliExpress Chinese.. "products" (to put it nicely) with a massive markup on...

Congrats on getting your overpriced euro trash up and running nicely ? ..and a happy new year too ?

Here I'm paying around £13 ($15) for a 3m 10ft length of the stuff I'm using, but it's 90% leftover stuff most of the time. I wouldn't even waste my time with wood with how long the pressure treated stuff lasts nowerdays.

Price dependent on location I guess. I don't see a massive difference here between uni and ally solar mount. I guess uni still comes in a little cheaper, I just happened to have a lot of it. I do think it offers more structural stability too though, which is why I used it on my ground mount...

Depending on the panel they tend to want to be fixed from the sides, although a mount from top to bottom may be possible its not very common. Standard aluminium solar panel clamps are more than adequate, they are somewhat ribbed and when tightened down, they don't move, no matter what. This is...

Only kidding, not very often I have to use the words I'm and wrong together, I swear ?

Sounds kinda dumb. Alright you win, I'm wrong. Ouch.

Maybe I interoperate what they say a little differently, not that I should think about it too much though, I don't even have a DC ground cable ?

Just quoting what Victron says.. If they feel the cable should be sized for the DC fuse, then I reckon the connection should be better too, albeit I understand there's not going to be any current passed in normal operation. Well I'm not sure in what situation it would ever pass current.. but it...

Yes but... "The DC ground cabling should have a sufficient thickness to be able to carry a fault current at least equal to the DC fuse rating" Still don't like a poor connection :confused:

Well if they used a yellow crimp the little gauge wire would just fall out ;)

That is referring to the cable connecting to the positive side which is easily removable, the one blue is pointing out is on the negative bar and the instructions state to place the lug over top of it.

Seems pretty poor to me, I was trying to work out what is was at first given I've only used modified Lynx Power Ins. I'm surprised there's not enough wire to remove it, would a slight disassemble of the unit allow the ring terminal to be released? Possibly removing the screws that hold the...

Its just.. magic and stuff. As far as I'm aware it means there are windings used to transfer the power from the solar side to the battery side with no direct connection between the two, minimising damage if a major fault occurred, meaning you wont get 400v of unregulated voltage and current...

Figured I'll throw this in, my CCGX is out in the power building, so I usually use my phone and the VRM app for monitoring and tinkering. Decided to pick up a cheap iPad and permanently mount it on the wall and leave it plugged in all the time displaying the VRM page, it's very useful, but now I...

Breakers or rotary switches? Rotary switches I don't have too much preference, obviously not the cheapest, but the way they work and the much bigger distance between contacts drastically reduces the risk of arcing and welding contacts together in comparison to breakers. As for breakers.. I...

I'm very wary of these cheaper DC circuit breakers.. although its their job, they don't like being switched off under load, at least not too many times. There are so many videos of them letting out the magic smoke. There must be a reason the branded ones (Schneider etc) are so expensive. I...

On the subject of cost.. I can't believe how cheap Victron has gone now! Just ordered a 250/70 for £430. 5kva Multiplus II is now £1300 with a free cerbo included Multiplus II is also on offer for buy 2 and get 1 free, that is £2600 for 15kva of 3 phase power :love: Just in time for a marine...

I think the record is broken..

90% 240v single phase. 400v 3 phase.

I wouldn't complain about a couple extra inches.

Build a bigger shed ? Or buy an AIO, whatever floats your boat. I've never run into a situation where I needed 8kw of power constricted to a space under about 300 square centimetres.

2x Mutliplus 2's 5kva - £3000 2x MPPT 100/150s £1000 Cerbo GX for communications £300 Pass through/UPS and load management are doable with the Multi. Give or take £4500 for the kit? I'm open to most brands, and have had many. I just happen to get on very well with Victron as I have had kit...

I still don't quite understand where this "Victron is so expensive, 10x the price!" stuff comes from? Especially if you are UK/Europe based. For instance.. A 150v 60a charge controller from Victron is around £450 a 150v 60a charge controller from Morningstar is (give or take) £600-700 a 150v...

I spoke too soon, well maybe not because of that though. I took it off a single cell and connected it to a series of 8 cells to charge them all, but I forgot to adjust the voltage from 3.65 to.. higher before doing so, and it let out a little magic smoke and now only kind of works. Maybe it's...

Just a very very quick test this morning before work, and I mean like 30 seconds. Nothing bad happened, it charged as it should for that short time, will try properly later.

I could really do with getting some of cells charged up.. I have a 10a bench supply with the intention of top balancing.. but with such a high deviation in my cells (0.2v) It's going to take too long. I hope this doesn't sound too dumb, but can I charge an individual cell with my power supply...

Unfortunately not possible to do 4s, as much as I'd like to. They are 37.5v VOC panels, and my controller is 150v max, a bit close to comfort for my liking.

Prior to upgrading to 48v, I ran a 24v system, with the solar capped to 60a. 8x 265w panels wired in 2s4p. Whenever the sun was out the controller always seemed to be capped at 60a (1.6kw) or there abouts. Now on 48v with a much higher PV input, I seem to be getting less power. I mean, it's hot...

I purchased one of these units from this shop, shipping was something like 8 days if I recall, 57v unit. Have only recently got it wired up, its purpose being to charge from my diesel generator which is capacitor regulated and it ain't pretty power. So now my Multiplus II can continue giving...
