V2H/V2G Bidirectional System
A general type of system that store energy for later use. This can include various technologies such as lithium-ion batteries, lead-acid batteries, or other storage solutions integrated with renewable energy sources. The primary purpose is to manage energy consumption, optimize renewable energy use, and provide backup power.

Working principle
01
Normal Operation
Works like a standard charger, optimizing solar self-consumption.
02
V2H (Vehicle-to-Home) / Blackout Mode
1. Grid fails -> Gateway disconnects home from Grid (Island mode).
2. Communication handshake verifies EV battery SoC is safe (e.g., >20%).
3. EV discharges power to the home panel to back up critical loads.
03
2G (Vehicle-to-Grid) / Trading Mode:
1. Utility sends a signal requesting power (during peak demand).
2. EV discharges energy to the grid in exchange for credits/payment.
3. User sets limits (e.g., “Do not discharge below 50% SoC”) to ensure driving range is preserved.
