BESS Solutions

A battery is just hardware. What makes it pay back is everything around it.

We import best-in-class BESS hardware, integrate it with your existing solar, DG, and grid connection, and run it through an intelligent dispatch layer that decides — every minute — where your power should come from.

How BESS Works

From assessment to commissioned asset, in four stages.

Every Harmonizer project follows the same disciplined sequence. No surprises, no scope creep, no commissioning that drags into the next financial year.

01

Energy Audit & Profiling

We pull twelve months of your electricity bills and 15-minute interval data from your meter. We map your demand profile against the applicable tariff schedule, identify your peak windows, and quantify the savings opportunity. This stage typically takes two weeks and is non-binding.

Inputs: 12 months of bills · 15-min interval data · single-line diagram · existing solar capacity

Output: Demand profile · peak-window analysis · indicative savings & payback
02

System Design

Based on the profile, we size the battery (kWh) and the inverter (kW) — these are two different decisions, and most under-performing BESS projects mess up the ratio. We model dispatch strategies, simulate annual performance, and present a fixed-scope proposal with a guaranteed performance envelope.

Sizing: Battery capacity (kWh) · Inverter rating (kW) · Annual cycles

Architecture: AC- or DC-coupled · Air or liquid cooling · Topology

Deliverable: SLD · Performance simulation · Commercial proposal
03

Supply, Install, Commission

We import the BESS modules, PCS (Power Conversion System), and BMS (Battery Management System) from vetted global suppliers. Civil works, electrical integration, protection coordination, and EMS configuration happen on-site. Typical project timeline is 12 to 16 weeks from PO to grid-tied commissioning.

Scope: Hardware supply · Civil & electrical · Integration · Testing · Commissioning

Timeline: 12–16 weeks from PO

Certification: CE / UL / IEC cells & PCS · CEA-compliant interconnection
04

Operate & Optimise

An AI-driven Energy Management System runs the asset 24x7 — forecasting load and solar generation, deciding when to charge and discharge, and ensuring the dispatch matches the tariff structure you actually pay. We monitor remotely, refine the algorithms quarterly, and provide a monthly performance report against the baseline savings we committed to.

Live dispatch: Solar priority · BESS arbitrage · Grid backup · DG last resort

Monitoring: Cloud-connected EMS · Real-time dashboard · Quarterly review

Guarantee: Performance reporting vs baseline savings
Use Cases

Four ways BESS pays back at an Indian factory.

In practice, most installations combine two or three of these. The EMS decides minute-by-minute which mode delivers the most value at that moment.

Peak Shaving

Discharge the battery during peak-tariff windows and high-demand periods. Your meter sees a flatter curve, demand charges drop, and time-of-day penalties disappear. For HT industrial users, this is where 60–70% of the savings come from.

Solar Firming & Time-Shifting

Capture excess solar generation that would otherwise be curtailed or exported at low feed-in tariffs. Use it when production needs it most — typically evening shifts or early-morning startup loads. Your solar plant effectively works 16–18 hours a day instead of 6.

Microgrid Integration

Coordinate solar PV, BESS, grid, and DG into a single intelligent network. The EMS decides which source feeds the load at any given moment based on cost, carbon, and availability. Renewables first, storage second, grid third, DG only when nothing else works.

Backup & Resilience

5-millisecond changeover during grid outages — fast enough that SCADA, PLCs, and sensitive equipment don't even notice. Combine with reduced DG run-hours to lower diesel consumption, maintenance, and emissions.

What We Deliver

End-to-end ownership. One accountable partner.

A

Battery Modules

LFP (Lithium Iron Phosphate) cells from globally vetted suppliers. Higher safety, longer cycle life than NMC chemistries — the right choice for stationary industrial duty cycles.

B

Power Conversion System

Bi-directional inverters that move energy between DC battery storage and the AC plant network. Sized independently of capacity for design flexibility.

C

Battery Management System

Cell-level monitoring of voltage, temperature, and state of charge. Active balancing extends pack life and protects against thermal runaway.

D

Energy Management System

The brain of the microgrid. Forecasts load and solar, optimises dispatch against the tariff schedule, manages the priority stack across all four energy sources.

E

Site Integration

Civil works, switchgear, protection relays, and metering. DISCOM coordination for interconnection approval. Single-line drawings and CEA compliance documentation.

F

O&M & Reporting

Cloud-connected monitoring, quarterly tuning of dispatch algorithms, monthly savings reports against your baseline, and a clear performance guarantee.
