Pillar guide
Battery & EV
Home battery storage, EV home chargers, and the emerging vehicle-to-grid systems that let a parked EV back up your house. Where the money is, and what to check before you buy.
Home batteries
Usable capacity (kWh), round-trip efficiency and cycle-life warranty are the numbers that decide whether a battery pays for itself — not the headline capacity alone.
EV chargers
A Level 2 / 7–22kW home charger cuts overnight charge time from a day to a few hours. Smart chargers can also shift charging to your cheapest tariff window or solar surplus.
Vehicle-to-grid
V2G/V2H lets a compatible EV's battery power your home during an outage or a peak-price window — still an emerging category, but the hardware and standards are maturing fast.
