So I have a 2.8 battery backup by luminous installed by a professional installer. I currently want to upgrade it to also charge with solar but I would like to do it diy. I have been doing a lot of research about it but I will like to peer review my math and numbers so I don’t damage my appliances.

So I have a charge controller rated for 30amp pmw from an earlier time.
It’s connected to a 150 watt solar panel 12 volts.

The current inverter is a 2.8kva inverter with 2 batteries. Which makes a 24v system.

Now I plan to order 2 more panels

1 200watt 12v panel
1 300 watt 24v panel

My plan is to connect the existing 12v 150watt panel to the new 12v 200 watt panel in series to make a 24v

Then connect the 24v in parallel to the 300 watt 24v panel.

This should give an output of around 28amps and 24 v
Which is about 650watt in total

The charge controller has a max of 780 watt for 24v

Is there an issue with this setup or am I making any mistake.
Is there any other device I need?
I know I need a surge protector and a DC breaker but not sure where to get those yet. Please house I need your help.

This your story no clear

A 12v solar array can't charge 24v battery
