Solis Three Phase Hybrid C&I Inverter: Price Guide for Industrial and Commercial Buyers

Tamil Nadu's industrial base, Chennai's automotive and manufacturing corridor, Coimbatore's textile and engineering clusters, Salem's steel units, Tiruchirappalli, Tirunelveli, and Vellore's mix of process and agro industries, runs on power-hungry equipment that can't always tolerate downtime. For sites that want solar generation and battery backup in one system, Solis's three-phase hybrid C&I range covers this need across two series: the S6-EH3P(30-50)K-H and the S6-EH3P(80-125)K10-NV-YD-H, together spanning 30kW to 125kW. This guide covers both series, where they fit across Tamil Nadu's industrial landscape, what shapes the price, and how to source genuine stock. Looking for a hybrid residential system instead? See our guides to the Solis single-phase hybrid residential inverter and the Solis three-phase hybrid residential inverter.

Model Overview

S6-EH3P(30-50)K-H

The S6-EH3P(30-50)K-H series covers the lower end of the C&I hybrid range, built for mid-sized industrial and commercial sites that want battery backup without stepping up to the largest capacity band. It's a genuine hybrid unit, charging a connected battery from solar generation and discharging it to critical loads or during a grid outage, with peak shaving support that shifts consumption away from expensive time-of-day tariff hours. Like the rest of Solis's hybrid range, it carries integrated AFCI protection, an IP66 rating on current models, SolisCloud remote monitoring, and a standard 10-year warranty extendable to 15 or 20 years.

S6-EH3P(80-125)K10-NV-YD-H

The S6-EH3P(80-125)K10-NV-YD-H series steps up for larger industrial sites and bigger commercial facilities, covering 80kW to 125kW on the same core hybrid functionality, battery charge/discharge, peak shaving, and unbalanced load handling, but sized for sites with substantially higher daytime load and a bigger appetite for backup capacity. Both series feed solar output directly to the grid under normal conditions and switch to battery-supported operation during an outage, unlike a purely on-grid inverter that shuts down for safety when the grid drops.

Available Capacity Options

Within the 30-50K-H series, the S6-EH3P30K-H suits mid-sized facilities with moderate backup needs, the S6-EH3P40K-H steps up for sites with a larger critical-load footprint, and the S6-EH3P50K-H tops the series for facilities approaching the upper end of mid-scale industrial demand.

Within the 80-125K10-NV-YD-H series, the S6-EH3P80K10-NV-YD-H fits larger industrial sites stepping into this higher capacity band, the S6-EH3P100K10-NV-YD-H suits bigger manufacturing or processing facilities with substantial backup requirements, and the S6-EH3P125K10-NV-YD-H covers the largest sites in this range, typically factories or facilities where a significant share of production load needs to stay protected during an outage.

As with the residential lines, the right variant depends on which specific loads, production lines, refrigeration, critical control systems, need to stay powered during a grid outage, not just the site's total connected load.

Where This Fits Across Tamil Nadu's Industry

Textile and Engineering Units

Coimbatore and Salem's textile mills and engineering workshops run continuous-process machinery, looms, CNC equipment, compressors, where an unplanned stoppage mid-cycle can mean scrapped material or damaged equipment, not just lost time. Battery backup on a hybrid system protects against exactly that kind of disruption.

Automotive and Manufacturing

Chennai's automotive and component manufacturing corridor, along with facilities in Vellore, runs production lines where continuity matters directly to output targets. A hybrid system here does double duty, offsetting daytime industrial tariffs while also protecting the line from voltage dips or short outages that would otherwise halt production.

Agro-Processing and Cold Storage

Facilities around Madurai and Tirunelveli handling food processing or cold storage depend on near-continuous refrigeration. A battery that bridges even a short outage protects stored product in a way an on-grid system simply can't.

Why Choose Hybrid Over On-Grid

Hybrid costs more than an equivalent on-grid system at this scale, so it's worth being clear on when that extra cost is justified.

Frequent or Unpredictable Outages

Industrial clusters, particularly those further from core grid infrastructure, can see more voltage fluctuation and short interruptions than well-connected urban areas, which makes automatic battery backup genuinely useful for continuous-process operations.

Time-of-Day Tariff Exposure

Tamil Nadu's HT industrial and commercial tariff structures include time-of-day components, and peak shaving lets a facility draw from battery during the most expensive hours instead of the grid, which can meaningfully affect a large site's monthly power bill.

Critical Always-On Loads

Production lines, refrigeration, and process-control systems that can't tolerate even a brief interruption benefit from a battery that takes over instantly when the grid drops, rather than a facility relying on generator backup that takes time to kick in.

If none of these apply and grid reliability at your site is genuinely stable, the simpler on-grid C&I line is usually the more cost-effective choice.

What Determines the Price

At C&I hybrid scale, several factors move the final number well beyond the base unit cost:

• GST at 12% applies on top of the ex-GST price, worth confirming on every quote

• Battery cost is separate: the inverter and the battery bank are priced independently, and at this scale, battery capacity is a significant line item on its own

• Series and capacity variant chosen: a 30K and a 125K aren't remotely the same price, so quotes need to specify the exact model

• Installation complexity: three-phase hybrid wiring, battery placement, and backup-circuit separation for a facility is considerably more involved than a residential job

• Order volume: multi-unit industrial orders typically come with better per-unit terms than a single-unit purchase

• Warranty tier: standard coverage is built into the base price; extending it adds a modest premium relative to the overall investment

• Genuine vs. grey-market stock: at this investment level, unauthorized stock risks losing manufacturer warranty support entirely

• State policy context: Tamil Nadu's renewable energy incentives are now administered by Tamil Nadu Green Energy Corporation Limited (formed in 2024 from the merger of TEDA and TANGEDCO's renewable wing), worth checking for current C&I terms

Because these factors shift with configuration, battery sizing, and order specifics, we don't publish a fixed number on this page. Get a current Solis C&I hybrid inverter quote for your Tamil Nadu site →

Summary

Solis's C&I hybrid range, spanning 30kW to 125kW across the two series covered here, fits Tamil Nadu's industrial and commercial demand wherever backup power matters as much as bill savings, textile mills protecting continuous processes, automotive lines that can't tolerate stoppages, or cold storage facilities protecting perishable stock. The final price depends far more on capacity, battery sizing, and installation scope than on a single headline number, so an itemized, project-specific quote is worth asking for directly.
