Trippledots:


It's a or with 2 normally open and 2 normally close connections. Grid goes to the coil, and also to the normally open or input. Inverter output goes to the normally closed input.

The normally open and normally closed outputs are interconnected and goes as the final output

How it works:
When there is power supply, the or energizes and closes the normally open s sending power out from NEPA.

Once Nepa goes off, or is de-activated and swings back to the normally closed position, sending power out from the inverter... I have a surge protector that helps with voltage fluctuations and also my stab has a delay timer that helps the overall function of the or.

Thanks for the detailed explanation. Whenever you have time help with a sketch of this connection. Nothing fancy, just a sketch showing these connections. Danke.

Oh! Na you I dey always see for my FYP

Nice job sir.

Dam5reey1:
Final results coming to YouTube and TikTok..

Abi make we just conclude..

Dam5reey1:


Glad it worked out!!

Knowledge sharing is on our vision..

So here is the Concluding part of the Haisic 4 19WH 12V Capacity test

At best this is a 3.7kwh so the 12v 280ah checks out. The 4kwh on the label is just the typical over inflation of capacity which most Chinese brands love to do.

Still impressed though.

Funny enough it's SON Label, it's the Chinese Label that carry 280AH

Damn, that's much better than I expected. 3.7kwh for 450k is an exceptional deal. Even better than the cheap Cworth 100aH unit.

Good stuff.

Just saw that they have a 25.6v 314ah battery for 800k. Going to be very hard to beat that price.

BTW, for your battery tests, you should consider doing a load test at the start. Maybe 0.5C discharge for a minute or two to see if the battery handles it. Should be helpful for people who want to run things like microwaves or industrial blenders.

Hopefully, you plan running the Fridge during the day alone, and would switch it off by 4:30pm abi do you intend running it at Night also ?

yes boss. That arrangement would definitely work for me. I have no prior understanding of required capacity. Kindly give me guidance/advice, boss.

oloet:
Let me laugh first, +9/-9v is too small in a direct DC application Are you joking? Though it is permissible in some cases with the presence of some circuitry, it won't end well in a direct DC application.

when you done LAUGHing, kindly note that most times, I comment what I do, even right now, I type from a Core i5 laptop, connected to a 24-inch external Monitor, all powered directly from a 12-volt source.

Not everyOne goes to youTube to learn; some of us actually play around till we inVent a method.

if you went through most of my comments, you would understand I actually explain to some extent what I actually did, like when I say "that an appliances has input of 21volts, doesn't mean the entire thing is used". Even your Tv, which mostly has input voltage of 220 to 240 volts, has big stepDown inside it.
How about computer Desktop U, that has input of 240volts yet the highest input voltage of the motherboard is 12volts.

dey there, if you like quote law of physics wey you no understand, or share link to review wey no relevant.


NO NEED INVERTing 12-volts to 240volts ONLY TO STEP IT DOWN TO 21-volots, WHICH WOULD GET FURTHER STEPPED DOWN TO SAY 11-volts

I ONLY NEED AN INVERTER IF I WANT TO RUN MY SUBMERSIBLE PUMPING MACHINE, OR FRIDGE, OR ANY OTHER MUCH HEAVIER APPLIANCES.
EVEN MY TV na direct to 12-volts, outDoor rotating Antennae that's meant to take 2400-volts, I removed the transformer inside it and converted the input wire to USB cable and connected it to laptop USB port, and it got powered by 5-volts.

My FANs runs much faster than your own FAN while connected to NEPA - because I connected directly to 12-volts battery, after bying the internal circuitry. Major reason when I wanna buy FANs, I shop for the bad ones.

Kindly share a clear picture of the sticker on the backer or front of your Fridge.

Also kindly note that 500,000 naira can't run the entire thing even if you choose to go with used Solar s, and Battery.

The battery is more than capable of 0.5C.. I don't bother doing High C rate cause at the end it's same results.

Who can please tell me why the ppv generated and the charging power are yards apart on this growatt inverter?

Conversion losses + your load = PV generated.

Also I wonder if what you see is in real time. That is your load consumption and battery charging power whether there is no lag.

No 5kwh 24v?

i can do it ,but not cost effective @ 1.1m, when my 7.5kwh is 1.250m

Please guys where is the telegram link to this awesome thread?
