iv found they dont really have a minimum voltage they just do what they do and send out 12v (mine do 12.1, 12.4 and a 12.3) even when batterys just at 12v they just dont do anything and pass the 12v through but its a risk im happy to take

Interesting, they may just stop regulating once the input gets below a certain point with the output transistor just continually turned on. Now that you've peaked my interest I might have to buy one to play around with.

there well worth the money just to play with,

i got mine off aliexpress
https://www.aliexpress.com/item/32518020047.html?spm=a2g0o.productlist.0.0.3467424asyHZcQ&algo_pvid=7afa770a-78e8-457c-b491-197080ee1ac5&algo_expid=7afa770a-78e8-457c-b491-197080ee1ac5-0&btsid=715c9bf5-fc21-4872-8cdd-1a80ca40d061&ws_ab_test=searchweb0_0,searchweb201602_7,searchweb201603_52

theres loads of little fun things to play with i also got a bunch of the 12v to 5v ones and connected them to usb hubs to run usb miners which worked a treat

My wife thanks you for the new influx of junk headed to my disaster of a workbench....

The DC/DC converters from your link along with one of these could work.

XD the epever charge controllers are suppose to be one of the best you can get on a budget (still saving to buy one) and tell your wife shes welcome.... its all fun.. wait till you get really good on aliexpress they sell things youve never even thought of.. only down side is sometimes the donkey they turn up on can take a very very long time.

You might be better off trying to use wind power if you can. We don't often go below 10 or 20 miles per hour here and if there's enough space for the solar panels, there should be enough space for the turbines too...

If you're going with solar panels, there are calculators as the others have siad that allow you to estimate how much power you're going to need.

If you're interested in upgrading an antminer S1-S5 then you might be fine with 300W, if not then you MAY need a better inverter, if the inverter is that low you might face issues with the batteries not being charged very well and them being drained extremely quickly (which may cause them to overheat or something if they're only getting a tiny amount in and it is immediatley getting taken out). If you can put up the funds, a 2000W inverter is about £200 on amazon. You might also have to account for the fact that we get 6 hours of sunlight in the winter and 16-18 hours in the summer per day.

dont think youd need an inverter at all if you can use a regulator he can go from 12v batter (14.4v at charge) straight to the miner (12v) and bypass both the inverter and PSU

That's a good idea, but an efficient DC/DC converter would probably cost more than the inverter and PSU combined. If you could find another 12 or so 12V batteries and put them all in series, maybe you could hack the PSU to run off the DC. Don't know if any charge controllers can handle so many batteries in series though.

if hes sticking with 12v i use a bigger version of these

its just to step the 14.4v down when its charging so it dosnt fry the miners. basically shove anything in get 12v out min cost £10 and are good for 400w (just about enough to manage a S7 blade)

Nice! Here's a 360W one:

You'd need to put the 2 batteries in series to get 24V to use one since the minimum voltage is 15V, and would have to verify the 12V is clean enough and regulated sufficiently for the input specs of the miner.

I would not recommend that, I think you might mean charge controller?

Solar panels normally need an inverter, often they're built in nowadays so no you don't need a separate inverter but it can help keep a safe power between the battery input and the solar panels...

do you mean a charge controller (charge controller between panel and battery) inverter to convert battery to what ever you want to power.

charge controllers are the brains controllig what goes in at what voltage and what comes out of the battery
