Hello Bro,

I have a setup already but I had to leave my inverter on 24/7 to power starlink when I am not home to manually change to grid power.

Can you tell me what I need or supply the items necessary to build an automatic changeover and integrate it with my existing changeover?

Valto:
so i wired a changeover between inverter and charger/utility, so that once utility becomes available, the output socket switches over from inverter to utility.
items used
4pcs of eve 100ah cells
120A JBD BLUETOOTH BMS
12V 1600w (800W continious power) pure sine wave sachet inverter
12v 20A dedicated lifepo4 lithium battery charger
10A relay

work to be completed tomorrow

What kind of inverter are you using?

suoer2kv modified sine wave

I can build an automatic change over for you. It will transfer load,put of the inverter and activate your charger (that's of if you have an external charger)

Your location?

I have an external charger connected to a socket linked to permanently to grid. When I am going out, I change over to inverter while the external the charger plugged in to grid to charge the inverter.

I will like setup to switch back and forth whenever there is grid power.

When do you want it done. It should cost around 20k to add that feature to the inverter.

Can you share steps and resources to achieve this?

Thats a bit steep bro and close to the price of those on the market. I can build it if you could sell me the components and share a schematic with me as I have the hands-on experience to soldier and use vero boards

Stop telling people to pay you for stuffs 😒 everybody here wants to DIY

If you are good with electronics, you can put together a relay circuit to do the switching when there is mains.

Check youtube

I only told him the cost.
Just like say it will cost you 100k to get a 60A lithium battery build.

Is that why you deliberately left out mentioning the parts that cost the said amount? 🤔

I mean, you said you did yours right? You must have a parts list or schematic don't you? unless sharing is an issue i don't see why you'd make it harder for someone else to be able to do what you claimed you did

After all, this is a DIY aka hobbyist thread

@FourQu

Please dont misinterpret Obnoxious.
By the way, I can charge anyone if you cannot go a diy route to build sth. Do you want such time to be free? The information on this thread is already free. Hope you know?

Such people @ bolded wouldn't & shouldn't be on this thread in the first place it's a DIY thread for goodness sake 🙄

When you see them please chase them away. Stop telling people to pay you to help them do stuff without first disclosing what it is they need to do for themselves

I have not done it yet.

But it's something that I can do .


For the parts you will need a relays, resistor, capacitors, diode, transistor, Vero board, soldering led.

Inverter uses the same thing just that it's microcontroller controlled.

The block diagram is something like this

Mains=> rectifiers> switch=> relays =>out put

The relay will be having 2 power sources

You are still not getting the point.
So let it go.

Thank you 😊

This is exactly what the thread was intended for 💯

Now a DIY enthusiast would know how to begin their tinkering and what materials to have on hand

No go burn your house you will be exposed to high voltage be careful
Goodluck on your quest.

Valto:
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 or.

make i no do promise and fail. am back with the wiring explanations

this is for a 12v 800w pure sine wave sachet inverter
12v 20A dedicated lifepo4 lithium battery charger
12v 100ah lifepo4 lithium battery
material used is an 8pin 10A relay

note if your load is above 500w, i will advise u use a stronger relay /or
i needed to get wires from 3 sources
1, from charger AC input source
2, from wires coming from inverter AC output
3 from inverter AC socket (note i disconnected wires soldered on the inverter Ac output socket)

then to the relay itself
it is an 8pin relay with socket

wires from inverter Ac socket goes to relay socket no: 1 and 8

wires from charger Ac source goes to no: 3 and 6

wires from inverter Ac source no: 4 and 5
in order to energise the coil, wire is tapped from no:3 and 6 to no: 2 and 7

make una vex for my not too detailed post, as me i no go school

And how is your opinion different from mine? 🤔

This one you said I'm wrong, me I no understand where you dey from come

It's like you don't understand what DIY means

D o
I t
Y ourself

It means I want to do it by myself. I want to buy the needed materials by myself. I want to connect everything by myself. I want to install it by myself. i understand the risks involved and still want to LEARN HOW TO DO IT FOR MYSELF !!!

If anybody feels it's too much then they can you for help, but FIRST offering to only help someone achieve a task here for a fee is against the core values of DIY you need to share with people how you do stuffs so they can then go ahead to Do It For Themselves . . . You get?

I no understand una. Go to DIY forums or threads on all other websites and check how it's done. Why are the Nigerians method always different

Leveraging people experience on A DIY is also against the ethics of DIY.

Because think about it, why do I have to share my experience if you decide to DO IT YOURSELF (DIY).

By DIY you learn everything yourself and ask questions when you are stuck.

You never do anything you dey ask question and process?.

Take your time and extract information research them then implement.

Those diy forums you are calling Will still ask for your progress.

So you've never come across the word 'newbie' before?

You no dey sound like newbie.

You be SNR man

Even newbie self dey get patience to learn and follow the process.

As newbie, if you can fund the project you can learn and build yours yourself
