Solis On Grid Inverters for residential, small commercial, and industrial use

Most homeowners going solar spend weeks comparing panel brands and barely think about the inverter until their installer hands them a quote. That's a mistake, because the inverter is what actually decides how much of your rooftop's solar output reaches your appliances, how safely it does it, and how long the system runs without a service call. This guide covers what makes Solis's residential inverter range a solid choice for Indian homes, how to size one correctly, and where to buy genuine stock.

Solis On Grid Inverters Residential, small commercial, and industrial use

Inverter for Home

Solis builds separate inverter families for homes, commercial rooftops, and utility-scale plants, and the residential line is purpose-built around a single-family house rather than a large roof or ground-mount site. These are single-phase string inverters (with three-phase options for bigger homes), generally ranging from about 1kW to 20kW, designed to sit close to living areas, run quietly, and connect to a handful of panel strings rather than dozens.

That's different from a commercial inverter, which is built for higher string counts and heavier daily runtime, or a utility inverter, which is built for MW-scale plants with high DC input voltages. A residential Solis inverter is optimized for a smaller, simpler installation instead.

Solis Residential Range and Specs

The residential on-grid line covers most Indian home sizes across three model families:

Across this range, Solis residential inverters typically deliver efficiency in the 98% to 98.8% band, with 2 to 4 MPPT inputs depending on the model, which lets the inverter track multiple strings independently if your roof has panels facing different directions.

Key Features That Matter for Indian Homes

A few design choices in Solis's residential line are worth knowing about before you finalize a model:

• Fanless, compact design: no moving parts to fail, and no fan noise near bedrooms or living spaces

• AFCI (Arc Fault Circuit Interrupter): detects dangerous DC arcing faults from damaged wiring and shuts the system down before it becomes a fire risk

• IP66 protection: on newer models safe for semi-outdoor mounting locations like a balcony wall or utility area, which is common in Indian homes

• Anti-PID function: protects panel output from degrading due to potential-induced degradation, a real issue in India's heat and humidity

• Bifacial and high-efficiency module compatibility: you're not restricted to one panel technology if you upgrade panels later

• SolisCloud monitoring: WiFi, RS485, GPRS, or Ethernet connectivity lets you track daily generation, faults, and performance from a phone app instead of walking out to check an LCD screen

Warranty and Reliability

Solis residential inverters up to 20kW typically carry a standard 10-year warranty, extendable to 15 or 20 years, which matters given that a rooftop solar system is meant to run for 25 years. Solis was also the first inverter brand to pass the DNV-GL (now PVEL) reliability test, and industry-reported failure rates for the brand run under 0.3%, low enough that warranty claims are genuinely uncommon rather than a formality.

For a homeowner, this translates to fewer surprise service visits and a stronger resale/valuation position if the property is sold before the system's rated life is up.

Choosing the Right Size for Your Home

A rough starting point, to be confirmed with your installer based on actual panel wattage and roof area:

• 1-2 BHK apartment or small home: a 2-3kW single-phase inverter usually covers lighting, fans, one AC, and a refrigerator

• Standard 3-4 BHK home: 3-6kW single-phase is the common range, especially with 2 ACs and regular appliance load

• Larger homes or villas with high AC load: 6-10kW, moving to three-phase supply if the house already has a three-phase connection

• Homes already on three-phase supply: the three-phase residential line (5kW-20kW) balances load better across phases and is worth discussing with your installer even below 6kW
