Solar panel wiring using Two charger controllers

Are those two different 12VDC systems or can you parallel join?

Connect the battery first to charge controller dude

Can I connect solar charger and normal battery charger both the on the battery?

Non Hybrid Inverter parallel connection

Ben bunun aynisini yapacağım ama regülatör invertor icinde olur mu?
24 volt 200 amper Lifepo4 akü şarj olacak. 1000+1000 güneş panelini

No, you don't connect your inverter to your load on your charge controller. Load on the charge controller is only for low amp DC like light's. Not a inverter that can pull 100 amps plus. You will destroy the charge controller. Why do people do that. I see it all the time. Even fused. 40 amp CC or 20 amp CC and so on isn't design high amps run through the load. It's for lights.

Can one solar panel be paralleled with two PCs and two separate batteries, not paralleled too?

There are so many errors with this drawing.
1. No fuses or circuit breakers are shown. That is a potential safety issue.
2. You have lines going to mysterious "12V DC Systems". The 12V DC systems should be connected to the battery if you want power when the sun is not shining on the panels.
3. You do not give specs on the MPPT controller sizes, wire sizes, Inverter sizing, etc.
4. If connecting the inverter output to the house, it needs to be connected to an isolator to prevent voltage feeding back into the grid in a power outage.
5. The inverter needs to be grounded.

Is this mean that 100ah battery must go with 150watt of solar panels?

Tell us the size of charge controller?

Do the controllers need to be identical. ?? Or can they be different size in voltage

Shouldn't the 12v inverter be connected to the load side of the scc? How will the scc cut off the load from the battery if it's connected directly to it? Low voltage disconnect and reconnect will seem pointless.

Very bad! Connect the modules in series and use an mppt controller. No pwm controller as shown here.

Can we charge lifpo4 wich has 4s 3.2v = 14. V 80 ah battery ?
