Solis Three Phase Hybrid Residential Inverter: Price Guide for Residential Buyers

Larger homes across Delhi, Noida, Gurugram, Ghaziabad, Faridabad, and Greater Noida increasingly run on three-phase connections, and for households in this segment that also want battery backup, Solis's S6-EH3P(8-15)K02-NV-YD-L series is the standard specification. This guide covers the series, its capacity options, what actually shapes the price, and where to buy genuine stock across the region. Have a single-phase home instead? See our guide to the Solis single-phase hybrid residential inverter for the 3kW-8kW range.

S6-EH3P(8-15)K02-NV-YD-L: Model Overview

This is Solis's three-phase hybrid inverter series, built for larger homes that want both higher capacity and battery backup in one system. It spans 8kW to 15kW on a three-phase connection, and being a genuine hybrid unit, it charges its connected battery from solar and discharges it to loads or during outages, with peak shaving support that shifts consumption away from high-tariff hours. It handles unbalanced loads across phases, comes with integrated AFCI for fire safety, and carries an IP66 protection rating on current models. Monitoring runs through the SolisCloud app with remote upgrade and control, and the standard warranty is 10 years, extendable to 15 or 20 years.

Available Capacity Options

The series is available in four capacity variants to suit different home sizes and backup requirements. The S6-EH3P8K02-NV-YD-L is ideal for larger three-phase homes with moderate backup needs. For bigger homes that require wider backup coverage across multiple circuits, the S6-EH3P10K02-NV-YD-L offers a balanced solution. Homes with higher simultaneous backup loads can benefit from the S6-EH3P12K02-NV-YD-L, which is designed for large independent residences. For the highest level of backup coverage, the S6-EH3P15K02-NV-YD-L is best suited for very large homes or farmhouses seeking near-complete power backup during outages.

As with the single-phase line, the right variant depends on which loads you actually want backed up during an outage, not just your total sanctioned load.

Why Choose Hybrid Over On-Grid

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

Frequent or Unpredictable Outages

Summer peak demand and periodic grid stress across the NCR region make backup power genuinely useful for households that can't tolerate downtime, particularly during heatwave months when AC load spikes across the grid.

Time-of-Day Tariff Exposure

If your DISCOM bills differently by time of day, peak shaving lets you draw from battery during expensive hours instead of the grid, which is increasingly relevant as time-of-day metering expands across Delhi, Noida, and Gurugram.

Critical Always-On Loads

Homes with medical equipment, work-from-home setups, or similar needs that can't tolerate downtime get added reliability from a battery that takes over instantly when the grid drops.

If none of these apply and your area has generally reliable grid supply, the simpler on-grid line is usually the more cost-effective choice.

What Determines the Price

At this capacity and product tier, a few factors matter more than they do for a basic on-grid system:

• 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 usually priced independently, so any "hybrid system price" should specify whether battery is included

• Capacity variant chosen: the 8K and the 15K within this same series aren't priced the same, so quotes need to specify the exact model

• Installation complexity: three-phase hybrid wiring, battery placement, and backup-circuit separation add more labour than a standard on-grid job

• Warranty tier: standard coverage is built into the base price; extending it costs a bit more

• Genuine vs. grey-market stock: especially relevant at this tier, given the higher replacement cost if something fails without valid warranty support

• State-level policy context: Delhi's rooftop solar incentives are administered through the Delhi Solar Portal, and NCR buyers in UP or Haryana should check their respective state terms separately

Because these factors shift with configuration, battery choice, and order specifics, we don't publish a fixed number on this page. Get a current Solis three-phase hybrid inverter quote →

Getting the Best Price on a Hybrid System

A few things worth confirming before you finalize a quote:

1. Ask whether the quote includes the battery or just the inverter: these are frequently priced and sold separately

2. Confirm the exact capacity variant: get the specific model (8K through 15K) in writing, not just the series name

3. Check authorized distributor status: warranty validity matters more on hybrid units given the added electronics

4. Ask about subsidy eligibility separately for inverter and battery: subsidy schemes typically treat the solar portion and the battery storage portion differently
