Balcony PV

Hi all,
I've been reading up and down, my head is spinning with options and devices. Thought I'd ask the pro's.
I'm planning to set up a balcony PV system with a little battery storage. What it should do:

- 2 PV panels, to be defined which kind, optionally expandable in the future
- max 800V/A AC output (hard limit or set by software)(it's the legal limit in Austria for non-registered balcony pv set-ups)
- LiFePo4 battery that's charged with excess energy from PV.
- NO feeding of energy to the public net.

How do I achieve this? Is it as easy as getting the SmartSolar MPPT charge controller of the proper capacity, connect PV and Battery and connect a Phoenix inverter to the 'load'?
How does the inverter 'know' what power to deliver to the home as not to drain the battery to the public net?
Would be great if someone could point me in the right direction - trying not to reinvent the wheel here.

thanks

Have a look at: https://www.victronenergy.com/live/ess:start and https://www.victronenergy.com/upload/documents/Wiring-Unlimited-EN.pdf

I'd recommend the EasySolar II GX. It's cost effective as it has all the main components you need and you'll learn a lot with that unit. I'd also recommend you put a DC breaker at battery positive and get professional assistance with any AC connectivity.

If you're trying to keep costs down, I'd consider a small stand-alone system. Most of us started small and incremented up over time. It's great fun but know the dangers.
