It will not charge properly,
when using 2 x 12V batteries you cant draw 12V off one, it just does not work.
In trucks if you have a 12V UHF radio connected to one battery that battery will fail, a 24 to 12 reducer is used.
You need that 24V inverter.Comment

ok i will get a dc converter, alot cheaper. thanks for your helpComment

No you cant use a 24 to 12 reducer for running your inverter, they are for small loads only.
You either need to charge and discharge your batteries at 12V or 24V,
You cant charge at 24v in series then just discharge one at 12V like you wrote but removed.
You either need to get a 24V inverter or a decent CC like sunking suggested so you can run your 12V inverter.
You rushed out and bought stuff at a stressful time, and are now getting an idea of how much it costs to set up a system so you can get some decent battery life.
You need to take a step back and decide whaty you want to acheive and how you can get the best result out of what you have.Comment

yes with a 24V inverter you can charge your batteries .
Make sure the 24V inverter is pure sine wave.
Your free power you talked about early on has vanished.Comment

its still free, the expenses to set up are for ASSETS. its not money pissed up against the wall like a power bill, also what can you run from the load terminal. the batteries are nearly charged and its only 10am.Comment

None of us including I expect you know what CC you actually need. He's just pointing out the CC you'd need to use all your panels in a 24v system. So how much power do you actually use in a day?Comment

You will figure out in two or three years when you replace the battery, it is far more expensive than the utility.MSEE, PEComment

if you do the sums on the cost of each KWH of electricity that you will get for the life of this system you will find you are paying way more than grid price.
How do you know your batteries are almost charged? The volts/amps readings only tell you part of the story. You will need a hydrometer at a minimum to to know where you batteries are at. If you dont learn how to properly understand your battery SOC you will likely ruin them in a very short time.
The load terminal should have a rating in amps, or you can run a relay off it and run more items. It may have some timer off/on functions.Comment
