Advice appreciated for my hybride 24 volt system ?

[Kevin_off_grid_tech]

Any advice please over my hybride 24 volt system. This consisting of 4x 280 watt sun panels, MPPT 24v hybride inverter/charger, 2x AGM 12volt batteries in series (24v), with a generator and grid connection also possible.
System needs a 24-12 volt converter as all DC led lamps, fans, usb and stereo are 12 volt.
I had an opportunity to buy a good secondhand 12 volt lithium battery and want to add this to this solar system. Charging this (I think) through a suitable AC 230 volt 12v battery charger.
I would really appreciate any positive corrections/alterations/additions to diagram. Parts I have already. Many thanks solar power people.

1. If it doesn't export it's not a hybrid. It's an off grid AIO.
2. You can buy a DC to DC converter/charger. But the simplest option is a cheap 12v solar charge controller. Just connect the solar input to your 24v battery bank.
Make sure you protect it with the correct size breaker or fuse.

Thanks for advice, do you mean a 24 -> 12 volt DC to DC charger or 12 -> 12v connected after my converter and connect to outlet of 24 volt batteries? And would the solar charger work better from outlet 24 v battery or 230 volt outlet plug ?
