Technical FAQs 3

What is an off-grid EV charging station?

An off-grid EV charging station is a self-contained power plant that can charge one or more electric vehicles without a permanent connection to the utility grid. Solar panels capture energy, a charger controller conditions the power, batteries store it for later use, and an inverter supplies the alternating current required by most chargers.

What makes a solar-off-grid Solar System a good choice?

Falling module prices, advanced lithium-ion BESS (including second-life EV packs), and modular power-electronics enable bankable designs from 5 kW to multi-megawatt scale. A solar-off-grid primer emphasises the importance of right-sizing each component so that generation, storage and load remain balanced across seasonal variations.

Can a rooftop PV system charge a passenger EV overnight?

Yes. A 5 kW rooftop PV array paired with a 10 kWh battery and a 7 kW AC charger can fully charge most passenger EVs overnight without importing grid power. How long does installation take? Fixed stations need 6–10 weeks for permitting, civil works and commissioning; mobile containerised units can be operational within a fortnight.
