Cut diesel by 80%.
Keep critical loads on.
The EAPVESS130K is a diesel–solar–storage hybrid microgrid in a cabinet. One intelligent controller runs your site on solar and stored energy first — and starts the generator only as a last resort.
The economics, at a glance
Every generator hour avoided is fuel not purchased.
Rs 21,140,000 gets you
The complete two-cabinet system — the equipment cabinet (bi-directional PCS, six-MPPT solar input, EMS microgrid controller, and the grid- and generator-communication/control interface hardware) and the battery cabinet (261 kWh LFP with liquid cooling, aerosol fire suppression and high-voltage box) — factory-integrated and delivered as one outdoor system. Not included: the solar panels (the cabinet provides the 260 kW PV input; panels are quoted separately), the diesel generator (the system connects to your existing or a new genset), and project engineering — utility/grid approval, protection study and settings, external ATS/switchgear, cabling and containment, civil foundations, and generator/ATS integration and commissioning — which are confirmed on a commercial site survey because they vary so much by site.
Indicative equipment price for the base configuration — one equipment cabinet and one 261 kWh battery cabinet. VAT, price validity and any exchange-rate adjustment, plus the solar array, switchgear, cabling, civil works, delivery and commissioning, are confirmed on your engineering quotation. Product images may illustrate a larger multi-cluster configuration.
One controller, four power sources.
Solar first
Up to 260 kW of PV runs the site and charges the battery through the day across six MPPT trackers — the site's lowest marginal-cost energy source.
Battery next
261 kWh of LFP storage carries the load into the evening and through peak-tariff windows. Expandable to a full 8-hour backup system.
Grid when useful
In grid-connected mode the system charges off-peak and discharges at peak for time-of-use arbitrage, with power factor ≥0.99 and THDi ≤3%.
Generator only as last resort
The EMS starts the diesel generator only when solar, battery and grid can't cover the load — reducing generator runtime, fuel and maintenance by more than 80%.
Why sites choose the EAPVESS130K.
Cut diesel by 80%+
Solar and storage do the heavy lifting; the generator becomes a rarely-used backup. EAST reports comprehensive energy cost reduced by up to 75% versus a diesel-only site.
Uninterrupted power
Millisecond-level switching (<20 ms grid/off-grid) and true black-start capability keep designated critical loads running through outages, subject to battery state of charge and approved site design. Highly sensitive equipment may still warrant a dedicated UPS.
Peak-shaving & arbitrage
Shift load out of expensive peak windows and, on grid, arbitrage the peak/off-peak price difference. Outcomes depend on tariff, load profile and operation.
Liquid-cooled, long life
Cold-plate liquid cooling holds cell-to-cell temperature difference under 3 °C, supporting >8,000 cycles and cutting auxiliary power by ~30% versus air-cooled cabinets.
Safe by design
Open aerosol fire suppression across the full cabinet, real-time safety monitoring with early warning, 3-level short-circuit and 4-level active protection, and per-pack aerogel insulation.
Built for harsh sites
C4 corrosion resistance (C5 optional), IP54 cabinet with IP65 distribution / IP66 PCS / IP67 battery packs — engineered for islands, cement plants and mining areas.
The commercial case for diesel displacement.
A commercial site running a diesel generator pays for every litre it burns. By putting solar and 261 kWh of storage in front of the generator and letting an EMS decide when — if ever — the genset runs, the EAPVESS130K targets a diesel-consumption reduction of more than 80% and a comprehensive energy-cost reduction of up to 75% against a diesel-only baseline (EAST figures). Fewer generator hours also means lower maintenance, less noise, and roughly 80% lower carbon emissions. In grid-connected mode, off-peak charging and peak discharging add a further arbitrage return. Actual savings and payback depend on your tariff, fuel price, load profile, solar sizing and how the system is operated — we model these for your specific site in the proposal.
