How much do you sell your products. Especially this one.

officialfestus:
calculate it by the output wattage you intend to draw from it.

capnies:
Thank you sir I intend to you 1000w continuous inverter

officialfestus:
calculate your power consumption to ascertain the required bms Amp rating best for your build.

capnies:
BUT NO HARM IF YOUR BMS AMPS IS HIGHER THAN YOUR CONSUMPTION. BECAUSE YOUR CONSUMPTIONS WILL VARY

Please, house..... Help me through this small project. I have a solar charge controller at home and also a car 12V inverter. A thought came through me yesterday that I can do a DC connection from the charge controller to the DC car inverter. But I will need that kind of switch used in a vehicle for the car inverter. I have uploaded all the pics for you all to see.

You don't need to bother yourSelf about such switch (or socket hole, if that's what you meant). Just connect / solder wire to the shiny strips

God will really bless you real good for your response. I would have done it your way but i also still use the inverter in my vehicle and i feel it would be a burden having to tack wires each time i have to remove it from my vehicle and use at home. That's why i want to use a socket.

I have another question. Is there anything like a specific DC cable/wire for this or can any wire work for it?

Another question. My inverter is currently in the repair shop and it is 24V. That car inverter is 12V. I don't know how the charge controller will react. The charge controller is idle for now that's why i thought of all these ideas. Is there some setting i need to apply on the charge controller to switch voltage?

A simple Paper Cellotape  should be more than enough, except you're itchy to spend money.

That thick Wire in the picture is good enough

Oga we arrest you oo.
This oppression is getting too much o . Joke apart, you are doing well. How you manage your time for this is amazing. Enjoy!

Hello boss I read somewhere were that you use Ethernet cables as your solar wire. I want to ask if you connected all the strings of coloured wire into one terminal or you divided them into fours for both terminal?

omakay:
I noticed something about your diagram. The positive connection you indicated falls on the negative terminal of the charge controller while the negative connection falls on the positive terminal.

Please check the diagram and talk about it. Thanks...

Not sure this place is meant for ADVERTs. Abeg take it to other threads.
if the other thread wasn't abused with ADVERTs, doubt @dollarnaira would have had any reason to start this thread.

everything I put here is solely to make the thread lively and more interractive. Posting the stuff I build, people ask questions about how these things are done and before u know it, knowledge is shared. How can we make it a lively thread if everybody is mute n not post what we do?
