Description

The Solis-(100–125)K-5G series includes 100kW, 110kW, and 125kW high-voltage three-phase inverters engineered for utility-scale and commercial solar installations. With 10 MPPTs, a >150% DC/AC ratio, and 99% maximum efficiency, it ensures maximum energy yield and flexibility in system design.

For safety, the series features integrated AFCI protection, Type II SPD on both DC and AC sides, optional PID recovery, and full compliance with global grid standards. Its IP66-rated enclosure, intelligent fan cooling, and capability to operate from –30°C to +60°C ensure durability in diverse environments.

Best Three Phase Grid-Tied Inverters for Solar Systems in India

If you're sizing up a commercial or large rooftop solar setup, your inverter choice matters more than most people realise.

A wrong inverter means under-utilised panels, poor grid sync, or costly replacements. A three-phase on-grid string inverter solves this it distributes load evenly across phases, handles higher input voltages efficiently, and communicates directly with the grid for net metering. The Solis 100–125K 5G is built precisely for this kind of demanding, high-capacity application.

Here's how to understand your options before you commit.

Comparison of Efficiency in Popular Three Phase Grid-Tied Inverters

Efficiency numbers tell you how much solar energy actually becomes usable power. Here's a quick benchmark of leading inverters in the Indian market:

What sets the Solis three-phase grid-tied inverter apart is its 5G platform advanced MPPT tracking, wide voltage input range, and real-time monitoring via SolisCloud. For commercial buyers comparing solis inverter 3kW price or solis 5kW 3-phase inverter price, Solis consistently delivers better cost-per-watt value against European brands with similar efficiency ratings.

Reviews of Indian Suppliers for Three Phase Grid-Tied Solar Inverters

Getting the hardware right is half the job who you buy from matters equally in India.

Things that separate reliable suppliers from the rest:

• Authorised distribution - ensures genuine product, valid warranty, and firmware support
• After-sales service network - inverters need commissioning, monitoring setup, and occasional firmware updates
• Technical support availability - especially for three-phase on-grid string inverter setups that require grid sync configuration
• Spare parts & replacement speed - downtime on a commercial plant is revenue lost every hour

Every unit is tested before dispatch, and our team supports net metering applications, SolisCloud monitoring setup, and post-installation diagnostics, not just the sale.

FAQs

1. Where to buy reliable three phase inverters for solar power in India?
   Buy from MNRE-empanelled, brand-authorised distributors who offer installation support, warranty registration, and after-sales service not just the hardware. Kondaas supplies genuine Solis three phase grid-tied inverters with full commissioning support across India.
2. How do I set Time-of-Use Tariff Charging on a Solis Inverter?
   Go to Advanced Settings → Time of Use on the Solis LCD display or via the SolisCloud app. You can programme up to 4 time slots per day to control when the inverter charges from grid vs. discharges to load, ideal for managing peak tariff hours.
3. How does a Hybrid Inverter support both Grid and Batteries?
   A hybrid inverter manages two power sources simultaneously; it prioritises solar, stores excess in batteries, draws from the grid only when both solar and battery fall short, and can export surplus back to the grid. It switches between these modes automatically, typically within milliseconds.etronixcenter+1
4. Is Solis 12kW three-phase?
   Yes. Solis manufactures 12kW inverters in both single-phase and three-phase variants. The S6-EH3P12K series is a three-phase hybrid inverter designed for large residential and small commercial PV energy storage systems, with a max efficiency of 97% and support for lithium and lead-acid batteries.

The inverters also provide intelligent string monitoring, smart I-V curve scanning, and remote firmware upgrades, making operation and maintenance efficient and future-ready. With compact dimensions and robust componentry, the Solis-(100–125)K-5G series is ideal for large rooftops, ground-mount solar systems, and utility-scale projects.
