Anybody with an idea of building an automatic change over?

u did not get back to me, been very busy though, but for the benefit of others here, i will try to explain it here tomorrow afternoon.
i will illustrate with a 10A relay, a battery charger, and a pure sine wave sachet inverter
note if your load is above 1000w i will suggest u get a stronger, higher rating relay or u incorporate a contactor.

This is the reason I don't usually read reviews from Nigerians on AliExpress. It often lacks depth. I often see things like these as reviews "Just received the package after 3 months, next time use SPEEDAF. Yet to open it, will review it after I've used it". Review done 4 months ago. No further review. No nothing. Just vibes

lolz, if u follow most reviews on Aliexpress, u will not buy anything grin

Good evening DIYers. Please bare with me, it's a long read.
Now to my question:What can I do to salvage my battery? Do I sell of as scrap? Are there buyers?

it can be reassembled as 12v 110ah,removing 4pcs of cells or getting a single 100ah cell to replace the damaged one. since cells make are different, an 8S 2A balancer bms can help to an extent, atleast it can be managed for the time being.

TechGeek777:
The way I see LiFePO4 Battery Packs from local builders here, if sellers are not ready to give documented 5 years warranty on Grade Band 7 years warranty for Grade A I will suggest the buyers look elsewhere.

My 20 cents!

i just hope u are not misunderstanding the post anyway, cos the jos guy JEMAG is a not a regular here. he only advertised here once and that was yrs back!

Interesting. What about the efficiency? Does it give close to 7.1kwh? That is what made me to just buy bluetti, because I will be sure of the capacity. I have a locally made power station but I don't even get half of the rated capacity.

probably a power station made with disassembled 3rd life cells. our cells are brand new. all are capacity tested are above rated capacity.
we also have a mobile power station, made with 4pcs eve 100ah cells
12v 1600w pure sine wave sachet inverter
12v 20A dedicated lifepo4 lithium battery charger
100A JBD Bluetooth bms
automatic changeover to utility once it is available

Also, I discovered that the inverter stops charging anytime I put on my 1.5hp Air conditioner or I am using Microwave
Valto

yes, those are heavy loads and your inverter may likely be pulling power directly from your panels and a little bit from your battery at that moment..

iCauseTrouble:
Please, is there a way to test for bad / fault battery in an inverter system? I noticed that my Eastman tubular battery bars in my inverter drops from 4 bars to 3 bars immediately it stops charging or when light is taken.
The batteries are less than a week old.
Also, is there a way to confirm the genuineness or authencity of batteries?

nothing much to worry about, tubular are known for vollage sag.
