In a balcony setup you’re likely dealing with limited solar panel area and constrained space for battery and inverter. The typical architecture when using a micro-inverter + battery might look like this:

• Solar panels mounted on the balcony or railing feed into a micro-inverter (which converts DC from the panels into AC for the home/grid).

• A lithium battery (e.g., LiFePO₄) is connected (via appropriate inverter/charger or hybrid controller) so that excess solar (or grid) power gets stored and then used later (at night, during peak rates, or for backup).

• The system may be AC-coupled (solar → micro-inverter →  battery → AC socket).
  The system may be DC-coupled (solar → battery → micro-inverter → AC socket) .

• Monitoring and control: The system smartly prioritizes solar use, battery charge/discharge, and grid interaction.
