Rs 718,000 gets you
The 20kW inverter head only. Not included: the 5.22kWh high-voltage battery modules and distribution box that stack into the tower (priced and sold separately), solar panels, and installation and wiring. Your energy consultant sizes the full tower on your quotation.
The 20kW head of an integrated tower.
All-in-one tower design
Inverter and battery modules in one integrated enclosure, a clean single-footprint install.
20kW three-phase hybrid
Self-consumption, storage and backup for demanding three-phase sites; EAST recommends around 40kWh of storage with the 20kW head.
Configurable storage
Stacks 5.22kWh high-voltage modules (750V series), about 20kWh per cluster and expandable to 63kWh.
High-voltage PV input
Generous PV headroom for strong daytime self-consumption, specified per site on the assessment.
One tower. Grows as you stack.
The 20 kW inverter head, 5.22 kWh high-voltage battery modules and the HV distribution box integrate into one tower — a clean single footprint instead of a separate inverter, battery bank and external wiring.
Add modules to grow storage. A starting cluster is about 40 kWh and the tower expands to 63 kWh — sized to your three-phase loads, with no separate battery cabinet.

System role
The inverter head of a KTH-S all-in-one system. Battery module count, PV array and backup scope are configured to your loads on the assessment.
Works with
EAST 5.22kWh high-voltage battery modules (750V series) and the EAST high-voltage distribution box.
Installation requirements
Three-phase supply; professional installation and sizing by MyEnergy Solutions.
Up to 10-year warranty
10-year warranty on eligible EAST ESS packages. Final warranty terms and covered components will be confirmed in your official quotation. Specifications are taken from the official EAST datasheet. MyEnergy Solutions is the authorised EAST Group distributor for Sri Lanka and the Maldives.
Savings: actual savings depend on your load profile, tariff, battery size, solar generation, usage timing and installation design.
No grid export needed: our systems are designed for self consumption, you use the power you generate in your own home. Savings projections do not assume export revenue. Any site-specific connection, protection or utility requirements are confirmed during engineering review.
Specifications and warranty: specifications per the official EAST datasheet; warranty coverage of up to 10 years, confirmed on quotation and local project scope.
