Three steps to your own power
Size it right
Use the instrument above for a real system and real savings against the May 2026 CEB tariff, not a guess, not a brochure number. You see the hardware and the price before anyone calls.
Free site assessment
Our energy consultants confirm your roof, switchboard and supply, then hand you a fixed proposal. No surprises on installation day, no moving numbers.
Install & switch on
Certified installation in a single day. Your system runs on self-consumption, so your savings never wait on utility approvals. The EAST monitoring app is set up on your phone before we leave. From the first sunny morning, you're generating your own electricity, typically 2 to 4 weeks from survey to switch-on.
A bill is a cost.
A system is an asset.
Money you'll never see again
- Every rupee you pay is gone. It buys nothing you keep.
- Tariffs keep being revised; the >180-unit block is now Rs 100/unit.
- When the grid drops, you're in the dark with everyone else.
- In ten years you've paid millions and own nothing.
An asset that pays you back
- Sunlight you've already paid for runs your home by day.
- A LiFePO4 battery shifts that power into the costly evening hours.
- Grid cut? You switch over in under 10ms. Most appliances never notice.
- After payback, enjoy 6,000+ cycles of near-free electricity. Payback period depends on your usage and tariff. See the calculator for your numbers.
When the grid goes dark,
your house doesn't.
Under 10 milliseconds: the fridge keeps humming, the Wi-Fi stays up, and the room never even flickers. No fuel, no fumes, no pull-cord.
Engineered to outlast the problem

Sized to your real loads
The inverter (kW) is the heart; the battery (kWh) is the fuel tank. A 6kW inverter comfortably runs an AC, the fridge, pump, TV and most appliances at once, with headroom for the kettle. We size both. We never sell you a box you don't need.
Instant switchover
A <10ms transfer means desktops don't reboot and POS terminals don't crash. EAST built their reputation on UPS systems. This switchover is their core competency. The inverter absorbs a 120% surge so pumps and compressors restart cleanly. Backed by the 10-year EAST manufacturer warranty. Covered components and terms are confirmed in your official quotation.
LiFePO4: the safe one
Lithium iron phosphate is the industry standard for thermal stability, with a per-pack fire-protection module. If one module ever faults, the BMS isolates it and the rest keeps running while you're alerted on the app.
Built for Sri Lanka
IP66 means fully dust-tight and sealed against heavy rain and coastal salt air. Natural cooling keeps it under 25dB, silent enough beside a bedroom wall. Rated to 60°C.
Two architectures, one platform
Single phase homes use a low voltage (LV) 48V battery stack, from 5 kWh up to 32 kWh, installed indoors. Three phase homes use a high voltage (HV) 750V integrated cabinet from 21 kWh, up to 63 kWh across three clusters. Both use LiFePO4 cells and the same EAST BMS.
Fuel your car from the roof
Charge overnight from stored solar or cheap off-peak power with an integrated EAST Atlas charger. Single phase homes: 7kW with 40A supply upgrade. Three phase: 11-22kW natively. Your roof can quietly run your EV.
Low voltage battery
For single phase homes (30A supply). Safe, compact, mounts on a wall inside your utility room or garage. Stacks from 5 kWh up to 32 kWh. Pairs with either single phase inverter, the EAHI-6000-SL 6kW or the EAHI10-12KSL 10 to 12kW.
High voltage battery
For three phase homes and businesses (60A+ supply). Higher voltage means less current for the same power, with thinner cables, lower losses, more efficient at scale. Stacks 21 kWh per cluster, up to 63 kWh across three clusters. Integrated into the EAHI10KTH-S all in one cabinet. EAST does not make a three phase LV inverter.
Straight answers.
