Taking lights and internet off the Grid (mostly)

I know.

That's why I ordered one, but Ari sent me a must (new version). On paper, the must looks better: https://www.mustups.com/new-arrival-80a-mppt-controller-5kva-must-power-solar-inverter/

It - together with my panels, microinverters, batteries, etc - is still lying in its box in the garage until I get money for someone to mount the panels. I'll do the wiring myself, but I want all cabling to run inside the wall. So I need someone who knows how to use a grinder because I'm scared shirtless.
How much did everything set you back?
Who is Ari?

Can this thing be upgraded with Lithium batteries down the line? How much capacity can be added without overly straining the thing? (charge controller?)
It doesn't have a lithium charging circuit, of that I'm almost 100% sure. If you buy that, I don't see why it won't work.

Something like this would be a lot cheaper: https://www.ellies.co.za/product/sinewave-inverter-with-trolley-2000va-modified-1200w/

And you wouldn't also need to wire it up to the DB board directly (and the cost for an electrician to do it to get a certificate of compliance).

The inverters are noisy though..
I have this invertor + 4 batteries, hardwired into the full DB so i can use anything as long long its not overloaded. mostly run some lights, wifi, alarm and can use TV as well.
On constant charge from 220V supply.
