Charge your EV from your roof, for about ₹1 a km.
AC wallboxes for homes and multi-bay charging hubs for businesses and fleets, with smart solar-priority charging so your car drinks daytime sunlight before it draws from the grid.
- 7 kW single-phase
- 11 / 22 kW three-phase
- Solar-priority charging
- Commercial multi-bay hubs
*Energy charges reduced to zero where rooftop space allows a system sized to full consumption; KSEB fixed charges continue to apply.

Built around how you use power
EV owners and buyers
A safe, dedicated wallbox is faster and safer than a plug point, and solar makes running costs very low.
Residential societies
Shared charging bays billed per use, powered by the common-area roof.
Businesses and fleets
Multi-bay hubs for staff, customers and fleets, with load management and metering.
Pick a charger
Solar-priority charging
The charger reads your solar output and fills the car from the roof first, drawing from the grid only for the remainder.
Scheduled charging
Set a window (for example 11 am to 3 pm, or overnight from battery) and the charger follows it.
Metered and controlled
App control and metering. Commercial hubs add load management across bays and optional payment.

EV charging: common questions
What is ‘about ₹1 per km’ based on?
An EV using roughly 150 Wh per km costs about ₹1 per km at a ₹7 per unit electricity tariff. With your own solar the marginal cost of those units is lower still. The calculator above uses editable assumptions.
Single-phase or three-phase charger?
A 7 kW charger fits a single-phase supply and recharges most cars overnight. Three-phase 11 or 22 kW chargers are faster where your supply and car support it.
Is there a subsidy for EV chargers?
We show state or FAME-related incentives only after verifying them, so none is displayed here yet.
Who executes commercial charging hubs?
Commercial EV hubs are executed by SURYOVA ENERGYGRID 24BY7 PVT. LTD., and the contracting entity is stated in the quotation before you order.
