Share your project details — site location, load or consumption data, and rough capacity requirement — and our team will respond with a technical and commercial proposal, typically including a single-line diagram and sizing rationale for BESS and PQ projects.
Facilities with heavy motor loads, VFDs, welding equipment, EPC/industrial plants, and any operation on an industrial tariff with reactive power penalties typically see the fastest, most measurable returns from power quality correction.
Yes — our Power Quality vertical is built around an audit-led approach: we assess your facility's power quality profile first, then recommend the right combination of SVG, ASVG, AHF, or HSVG equipment rather than defaulting to a one-size-fits-all solution.
Yes. Many industrial tariffs penalize low power factor and high reactive power draw directly on the bill, and poor power quality also causes energy losses and premature equipment wear that add indirect cost over time.
Common signs include unexplained equipment failures or nuisance trips, flickering lights, overheating transformers or cables, electricity bill penalties for low power factor, and unstable performance from VFDs or automation equipment.
Broadly: SVG handles reactive power compensation and voltage stabilization; AHF (Active Harmonic Filter) targets harmonic distortion from non-linear loads like VFDs and rectifiers; ASVG and HSVG are hybrid/application-specific variants combining reactive compensation with harmonic filtering for more demanding industrial loads. The right choice depends on your specific power quality issue — we recommend a PQ audit before specifying equipment.
An SVG is a power electronics device that dynamically injects or absorbs reactive power to stabilize voltage and improve power factor in real time — far faster and more precisely than traditional capacitor banks.
Power quality refers to how stable and clean your electrical supply is — covering issues like voltage fluctuation, harmonics, and reactive power imbalance. Poor power quality can damage sensitive equipment, trigger nuisance trips, increase electricity bills through penalty charges, and reduce the working life of motors and drives.
An AC-coupled BESS can typically be retrofitted onto an existing solar plant without re-engineering the solar inverter setup, making it a practical option for facilities that installed solar first and want to add storage later.
Yes, when configured for it. A properly sized and configured BESS can pick up critical loads during a grid outage, often faster and more quietly than a diesel generator, and can be paired with a DG for longer-duration backup.
Payback depends heavily on your local tariff structure, demand charges, and use case (peak shaving vs. backup vs. solar-plus-storage), so it varies project to project — we build project-specific ROI calculations as part of every BESS proposal rather than quoting a generic number.
Sizing is based on your load profile — typically analyzed from 15- or 30-minute interval consumption data — your tariff structure (e.g., HT/LT category), backup duration needs, and whether the primary use case is peak shaving, backup, or solar self-consumption. We run load-profile-based sizing exercises for C&I customers as a standard part of our BESS proposals.
Both configurations are possible. We design solar-only charging setups as well as hybrid configurations that draw from the grid or a diesel generator (DG) with load sequencing, depending on your tariff structure and backup requirements.
An AC-coupled BESS connects to the electrical system through its own inverter, independent of the solar inverter — making it easier to retrofit onto an existing solar plant. A DC-coupled system shares a common inverter with the solar array, which can be more efficient for new-build projects but is harder to retrofit onto existing installations.
A BESS stores electrical energy — typically from solar or the grid — for use later, enabling peak shaving, backup power during outages, better solar self-consumption, and reduced demand charges for commercial and industrial consumers.
Yes — both are established, compliant BOS (balance-of-system) brands used across Indian solar installations, and we supply them alongside inverters and modules so EPCs can source a matched electrical BOM from one distributor.
Lead times vary by product and order volume, but our regional warehousing in Pune, Ahmednagar, Nagpur, Bengaluru, and Hyderabad is designed to shorten delivery timelines versus single-point national dispatch. Share your project timeline and we'll confirm current stock and lead time.
ALMM (Approved List of Models and Manufacturers) is a government-maintained list of module manufacturers approved for government-linked solar schemes. Buying ALMM-listed modules is typically required for eligibility under schemes like PM Surya Ghar and most utility tenders — ask us to confirm listing status for any module we quote.
Yes. As a Sungrow channel partner, we support genuine spares sourcing and coordinate service and RMA (return merchandise authorization) for existing installations, not just new sales.
All three. Our product range spans residential string inverters through to 300kW+ utility-scale platforms, and our module and BOS partners cover projects from a few kW up to multi-MW installations.
Sizing depends on your DC/AC ratio target, module wattage and string configuration, site irradiance, shading profile, and grid connection voltage. We help customers work through this sizing exercise as part of our proposal process — share your site and load details and we'll recommend a configuration.
String inverters (like Sungrow's SG-HX series) distribute MPPT tracking across multiple smaller units, which improves harvest under partial shading and irregular terrain and simplifies maintenance, since a single unit failure affects a smaller portion of the plant. Central inverters concentrate capacity into fewer, larger units, which can lower per-watt hardware cost but concentrate failure risk.
Celestial Renewexperts LLP is an authorized Sungrow channel partner (since 2017) with regional warehouses in Pune, Ahilyanagar, Nagpur, Bengaluru, and Hyderabad, supplying genuine stock with local technical and O&M support.
Our solar portfolio includes Sungrow inverters, Saatvik and Emmvee solar modules, Cahors connectors, and APAR cables — covering the full electrical BOM for a solar plant, not just the inverter. In Power Quality, we supply Active Harmonic filters, Statis VAR Generators for inudustrial and commercial consumers, and also to contractors and integrators helping clients.
Yes. We have been a Sungrow channel partner since 2017, supplying genuine Sungrow inverters and PowerStack battery energy storage products with manufacturer-backed warranty support.
Celestial Renewexperts LLP is a renewable energy distribution company operating across three verticals: solar products distribution, battery energy storage systems (BESS), and power quality solutions. We supply, design-support, and service equipment for residential, commercial & industrial (C&I), and utility-scale projects.
