painful images :-(

OK cool , i thought so but just wanted it confirmed Ok to move to that pack is quick and easy, easy install of 3 short cables Interesting that the load/Charge + has moved to bottom right post I shall experiment with that first, i think my preferred method is "method 3" easy to understand...

Ok just checked the voltages of each battery , the left bank were all lower so i would say that means the original way i wired , very first image , in my very first post in this thread was , "operable but poor " :) I have just rewired and using bottom right post for charge / draw , lets see...

I think im upto about 40 screws from taking the case cover off to remove this motherboard, phew I have FOUND the issue (or one part of issue , who knows it might have damaged components further down the track ) , i shall upload images in a moment or two in the next thread for anyone else...

looks like i need to learn the difference between pwm and mppt then ........... " gooooogllllleeeee"

the Ac should be 12 AWG, i thought to myself this is a bit thin , when i used for both I used lot thicker for connecting the batteries , but no for the lead to charge the batteries from the charge controller No luck here with anyone with experience on these yet , looks like i shall have to...

So under the floating top board i found a bank of fuses :) they are not like a car , even though they look like car fuses they are soldered on. Visual inspection they seem ok , guess i should continuity test them !?

oh what a week ! blew up a charge controller and installing a nebra hotspot as a newbie and its driving me crazy , as well as learning about antminer cypto mining ...too much learning this week , puffed oot Nebra Hotsot : frickin thing stuck on 64% sync for 5 days ! tired of checking waiting...

the solar panels and batteries are still working fine when tested with multimeter when i attch the following to invertor .... batteries : nothing solar input : nothing AC power : Lcd screen cycles on and off

I was running 4 x12v batteries at 24v all was fine I have now expanded to 8 x 12v batteries at 24v and wired like image obtained from the web , all is working fine but im not comfortable with it , is there a better way ?

Subject Edited to get the attention of the repair techs , or anybody with the ability who wants it, in its broken condition please feel free to make me an offer to save it sitting in a box in the garage for the next ten years. vevor 3kv : Smoked : anybody want it ? repair it ? £50 plus postage...

Just going to rewire just now and spotted a difference between images although they look similiar the image i put up, you draw + from top right post the image mr sandals put up you draw + from bottom right post any thoughts anyone ?

Im looking for something that goes between batteries and load that cuts out at say 21v and returns power to load at say 27v

Ah , its to go between the battery and the inverter , its to turn the invertor off and on based on battery bank power level

I bit the bullet and ordered a Victron non smart one any ideas for cheaper non branded ones im still in the market for more any leads / ideas appreciated

When im back up and running i wont be playing too much likely 600w or less and will be taking advice from here on the correct wiring , batteries etc ............ in the meantime before i click buy on another unit the manual is pretty generic to a lot of units , useful if the thing turns on ...

Hiya totally gutted,i managed to smoke my vevor mppt 3kv hoping someone can recognise symptoms or suggest a repairer ( Uk ) I don,t have a guarantee as i bought second hand and support for repairs of vevor products in Uk seem to be non-existant this is a total garage project with never any...

Thankyou , the smart guage link a lot easier for me to understand , although i need to put some thought into it for 24v once i have decided which method i prefer it was worth reading just for this comment , which have been wondering :) "And finally, finally, we keep getting asked where the...

The blue lines , what do they represent ? , might seem obvious to you , but just confusing me :)

its useless to me ! Price reduced vevor 3kv : Smoked : anybody want it ? repair it ? £40 plus postage if anybody wants to buy it in its current broken condition

thanks for taking time to reply pic attached no obvious fuses to my eyes sadly , that would be too easy

Parallel all was well for a while, never saw Voltage go above 36v from memory the system went POP when i tried to draw too much power system did not go POP , while i was sleeping , it didnt even go pop 5 minutes before or 5 minutes after , it went POP when i cranked up the power usage ...

Sooooo what do you guys think of this method ..... see attached file. Key difference is the charge controller volts in are at the opposite poles from the load draw I cant say if its good or bad , just looking for opinions in my head it makes sense ....

I was drawing 500 watts from battery pack fine for days , then i decided to play , pushed it to 2800 watts power draw and the battery wires melted and that mosfet went POP nothing dramatic just stopped working i have the mosfet on order hopefully arrive soon and i will solder it in and see if...

the manual indicated 12 awg , thats what i was using but i was stupid pushing it too far im also a novice to solar and electrics playing in the garage which is far way from house :) as i was just testing ( playing ) i hadnt put an inline fuse in it yet

In the same vain , im not saying good or bad , but just read this ................. "The battery cables should be of the same length and same size and as straight as possible. Always connect loads and charging sources to positive and negative terminals at opposite ends of the battery bank...

Looking for battery protector - battery guard Theres a large brand name company ( V .... ) out there selling a battery protector / battery guard but their various versions are $80 - $160 Terrific value if your spending $10k on a lifepo powerwall however im experimenting in the garage with...

I have nae idea what that means :) im am just playing with car batteries , lead acid

Clearly, some people have the ability to fix these things I have given "specialists" on this specialist forum the chance to help or have cheap for repair but it seems no takers so off to ebay and if that does not work , landfill

Interesting i had never thought of disabling speaker however is it a clean start ? and clean cut off im concerned the solar would almost immediately restart the invertor not giving chance for batteries to recharge a bit and the load would immediatly drain it again so it would go into a...
