Solis Inverters: Ginlong’s String and Hybrid Power Strategy

Solis Inverters are the grid conversion and energy storage products of China’s Ginlong Technologies. The company still builds its business around string architecture, but its growth strategy now reaches far beyond conventional solar conversion. Ginlong is adding hybrid power control, batteries, cloud monitoring, and automated energy management across residential, commercial, industrial, and utility applications.

That shift matters because an inverter now influences battery economics, backup performance, grid compliance, software control, and long-term service risk. A current assessment must therefore examine the whole operating system, rather than compare efficiency figures alone.

What Are Solis Inverters and Who Makes Them?

Ginlong Technologies develops and sells its inverter portfolio under the Solis brand. The Ningbo company trades on the Shenzhen Stock Exchange under code 300763. 

The company’s 2025 annual report shows how broad the business has become. Ginlong reported CNY 6.952 billion in revenue, up 6.26 percent, and CNY 743 million in net profit attributable to shareholders, up 7.53 percent. Its core operations covered string inverters, distributed photovoltaic generation, and newly developed energy storage systems.

The audited product range included grid-connected residential models from 0.7 kW, commercial models from 50 to 200 kW, and ground-mounted models from 230 to 350 kW. Storage inverter categories ran from 3 kW household units to 125 kW commercial systems. 

Ginlong reported a maximum inverter efficiency of 99.1 percent across its portfolio, although actual performance depends on the model and operating conditions.

Financial Performance and Market Position

The company’s market position strengthened considerably in 2025. According to Wood Mackenzie, Solis ranked No. 1 globally in residential inverter shipments. 

The company also continued its recognition as a BloombergNEF Tier 1 PV Inverter Manufacturer for Q1 2025, a designation awarded to manufacturers demonstrating strong bankability and consistent product performance. 

In India, the CRISIL–Bridge to India Rooftop Map (June 2025) ranked Solis as the No. 1 inverter supplier in the rooftop solar segment, accounting for 25% of total deployments

How the Solis Solar Inverter Portfolio Is Structured

The Solis solar product architecture spans residential inverters, commercial inverters, utility-scale inverters, and hybrid inverters. Buyers should compare the correct regional model because power classes, grid approvals, connectors, battery lists, and software functions differ across countries.

Product layer	Main role	Current strategic value
Residential grid-tied	Converts rooftop PV output for household use and export	Compact deployment, multiple array orientations, and consumption monitoring
Commercial string	Manages larger rooftops and distributed assets	Multiple MPPTs, export control, safety functions, and third-party integration
Utility-scale string	Serves ground-mounted projects at higher voltage and power	Modular field design, granular monitoring, and reduced single-point exposure
Hybrid and storage	Coordinates PV, batteries, loads, grid supply, and generators	Backup, tariff response, peak management, and flexible energy use

The S6 series now carries much of the company’s product development. It spans residential grid-tied equipment, commercial units, utility-scale products, and Solis hybrid inverters. The older RHI hybrid inverter family remains visible in current Solis support materials, but the S6 naming now signals the newer generation across many markets.

This segmentation explains why a single Solis PV inverter verdict has limited value. A household export-only system, a factory with peak demand charges, and a solar farm face different operating requirements. Model selection must start with the electrical design, local grid code, load profile, and service arrangement.

Residential Hybrid Power Is Moving Toward Whole-Home Control

The Solis hybrid inverter proposition now centers on energy orchestration. In September 2025, Solis launched a 9.6 to 16 kW low-voltage residential hybrid series for North America. The platform included a 200-amp pass-through, automatic bypass, a configurable smart port, generator support, and microgrid operation. Battery charge or discharge current reaches 290 amps. 

These functions reduce external hardware and give installers more design choices. Still, compatibility must be confirmed at the model level. Battery voltage, communications protocol, firmware, backup loads, and local approval determine if the promised functions work as designed.

Commercial Hybrids Combine More Control Functions

Solis also introduced 30 to 60 kW commercial hybrids in the United States during 2025. The series supports generator connections, flexible battery configurations, high-current modules, and capacity expansion. TÜV Rheinland later awarded the series a cTUVus mark following evaluation against US and Canadian requirements. 

At Intersolar Europe 2025, Solis debuted its 75 to 125 kW three-phase wall-mounted hybrid series. It incorporated ten MPPTs, two independently controlled battery ports, generator coordination, and parallel operation. The official launch details show a clear attempt to compress several commercial energy functions into one power electronics platform.

SolisCloud Turns Hardware Into an Energy Management Platform

SolisCloud connects inverter monitoring with plant commissioning, alarms, organization management, operating data, and remote settings. Official 2025 guidance covers account setup, plant creation, dataloggers, alarms, and organization access. Its importance grows when a Ginlong Solis inverter controls storage because software decisions affect charging, export, backup reserves, and tariff response.

Solis began rolling out Solis AI in Europe during 2025. The software forecasts generation, analyzes consumption patterns, and schedules battery behavior around dynamic prices. It runs within SolisCloud for systems on supported firmware, without added control hardware.

The commercial logic is significant. Hardware efficiency gains have become incremental, while software can influence daily energy value. Solis can now compete across device sales, system integration, monitoring, service relationships, and future energy management features.

The 2026 Move From Inverters to Integrated Storage

The company advanced this strategy in 2026 with integrated energy-storage systems. FlexAIO combines a high-voltage battery, inverter, and energy management in a stackable residential system. 

EverCore: From Inverter Maker to Energy Solutions Provider

In November 2025, Solis launched EverCore, the company’s first all-in-one commercial and industrial energy storage system. The system combines inverter, battery, and energy management system technology within a single package. EverCore debuts in two configurations: a 100/120 kWh system paired with a 50/60 kW hybrid inverter, and a 261 kWh model supported by the 125 kW hybrid inverter.

The system is IP66-rated for outdoor use, supports modular expansion up to 1.25 MW / 15.66 MWh, and switches between on- and off-grid in under 10 ms. It uses high-capacity 314 Ah LFP cells with multi-layer protection and a patented air-cooling design

Execution moved beyond exhibition launches in July 2026. Solis reported its first UK commercial battery installation at RJAH Hospital, using six 109 kWh batteries paired with six 50 kW hybrid inverters. 

This development changes the competitive frame for Solis solar power. Ginlong can sell a coordinated system instead of relying solely on the inverter inside a multi-vendor design. Integration can simplify procurement and support. 

It can also deepen vendor dependence, making software access, replacement terms, data portability, and battery service more important during evaluation.

What Buyers Should Check Before Selecting a Solis Inverter

A technically suitable Solis solar inverter still requires commercial and operational due diligence.

1. Confirm the exact regional SKU, grid certification, environmental rating, and approved firmware.
2. Match PV voltage, MPPT layout, module current, battery voltage, and backup demand to the design.
3. Verify battery compatibility through the current country-specific list, rather than a distributor’s general statement.
4. Test SolisCloud permissions, alerting, remote settings, data export, and installer handover before acceptance.
5. Document local warranty responsibility, replacement stock, response times, and firmware support.
6. Review cloud hosting, remote access controls, update governance, account ownership, and incident procedures.

The final point has become commercially material. Reuters reported in May 2025 that US energy officials were examining undocumented communications components found in some Chinese-made solar equipment. The report did not attribute those devices to Solis. It did show why cybersecurity evidence now belongs beside efficiency, price, and warranty in connected equipment procurement.

What Ginlong’s Strategy Signals

The current Solis solar inverters portfolio reflects a familiar Chinese technology scaling model. Ginlong retains manufacturing strengths, expands across use cases, localizes products for regional rules, and moves into higher-value control layers.

The 2025 financial mix makes storage the central growth signal. The 2026 integrated systems push that logic further. Ginlong’s next test will involve execution across batteries, software, certification, service, and data governance. Product breadth creates opportunity, but long-term value will depend on how consistently the company supports each regional ecosystem.
