Solis: Solar inverters and hybrid storage systems from Ginlong Technologies

Solis is Ginlong Technologies’ inverter brand, spanning residential, commercial and utility solar, hybrid storage and system monitoring.

Summary

Best for
Residential and commercial PV installations needing an inverter portfolio with regional grid variants and hybrid battery options.
Less suited to
Projects requiring an unrestricted public register map for immediate third-party controller integration.
Deployment
On-site inverters and communications equipment; optional SolisCloud monitoring.
Data in
PV strings, battery BMS, site meter and grid measurements; model-specific CAN and RS485 interfaces.
Pricing
No uniform public system price; hardware, batteries and installation are separate project costs.

Overview

Ginlong was founded in 2005 and listed on the Shenzhen Stock Exchange in 2019. Its company history places Solis across residential, commercial and industrial, and utility-scale solar and storage. The portfolio is broader than a single hybrid inverter: it includes conversion equipment, site communications and monitoring around the installed power system. The useful distinction is between a grid-connected PV inverter and a hybrid product with battery and backup functions. Regional grid requirements and exact hardware suffixes remain part of the product identity; a family name alone does not establish the same voltage class, battery interface or commissioning workflow across markets.

Offering

The S6-EH3P commercial hybrid family includes a 50 kW model with four MPPTs and two battery ports. Its retained V3.8 global datasheet specifies 150–800 V batteries and separates recommended PV array size from usable PV input power. Those are family-specific specifications, not universal Solis limits. The S2-WL-ST logger provides another integration layer: its documented Modbus TCP mode exposes a local network connection but disconnects that logger from SolisCloud when enabled. SolisCloud serves the remote monitoring workflow, while the inverter’s local screen and electrical interfaces retain separate roles. Battery selection, monitoring hardware and inverter conversion therefore form distinct parts of a system quotation.

Products and platforms

  1. S6-EH3P(29.9–50)K-H

    Commercial hybrid inverter

    Three-phase high-voltage hybrid family; exact 50kW model has four MPPTs and two battery ports.6

Technology

The European S6-EH3P manual distinguishes the battery CAN connection, meter RS485 connection, parallel-inverter ports and external-controller interface. An RJ45 connector does not by itself mean Ethernet: the optional RS485 connection uses pins 5 and 4 for A and B. The manual also describes a master-controller use for that port, so its role cannot be assumed to be a passive monitoring server in every configuration. Solis’ current protocol-access policy asks qualified partners to submit requests for Modbus tables, with NDA requirements reviewed by its product team. That is a material difference from vendors publishing complete current register maps openly. A cloud monitoring account does not substitute for that local protocol agreement.

Customers

Solis’ published projects illustrate different uses of the same commercial hybrid platform. Its Pärnu metal-industry case identifies a 100 kW installation using the S6-EH3P50K-H and Dyness battery equipment. The case does not name the industrial customer or establish a universal compatibility list for other battery firmware. At Ferndale Farm in Zimbabwe, Solis describes two 50 kW hybrid inverters with 100 kWh of Greenrich storage, supporting equipment such as cold storage and milking facilities. These are manufacturer-reported deployments, not independently verified performance trials. They show the product’s commercial and agricultural applications without establishing lifetime savings, outage duration or identical equipment approval in Europe.

Markets

The corporate profile describes residential, commercial and utility markets, supported by regional offices and service centres. The official contact directory separates the Ningbo headquarters from European, American, Australian, Indian and other operations; those regional addresses are not separate headquarters for the listed parent. Product documentation is similarly regional. The retained hybrid manual is a European edition, while the linked family datasheet is global and lists multiple grid standards. A standards list is broader than an individual installed system’s approval. The resulting selection process depends on an exact regional inverter, the applicable grid connection arrangement, a matched battery and the local support channel.

Company

Solis is the inverter brand of Ginlong Technologies Co., Ltd., rather than an unrelated company sharing the Solis name. The Chinese corporate profile identifies the listed company, founder Wang Yiming and stock code 300763, and dates the Shenzhen listing to 19 March 2019. The headquarters contact page gives an address in Xiangshan, Ningbo, Zhejiang. The company’s own global history dates its establishment to 2005 and describes successive inverter generations and expanded research capability. Its operating footprint combines Chinese development and manufacturing with regional sales and service. Corporate scale claims and awards are company-reported; they do not replace product-level electrical limits, protocol documentation or evidence for a particular integration.

Assessment

A broad inverter manufacturer with useful model-specific manuals and commercial storage examples. Integration planning must distinguish local electrical interfaces from the logger/cloud path and account for controlled access to current Modbus tables.

  • Interoperability

    Company sources Separate documented electrical interfaces and a logger TCP path exist, but current protocol tables require a reviewed request.

  • Scale

    Company sources Manufacturer-reported commercial hybrid deployments in Estonia and Zimbabwe establish applications in two markets; the score does not infer deployed digital scale from manufacturing capacity.

    Sources: 1, 11

  • Stability

    Company sources Parent Ginlong Technologies was founded in 2005 and listed in Shenzhen in 2019.

    Full note and sources

    These facts establish corporate tenure and ownership visibility, not a guarantee of future support.

  • Functionality

    Company sources The scoped S6 hybrid documentation describes PV conversion, two battery ports, backup supply and operating modes.

    Full note and sources

    This score concerns those documented hardware functions, not a verified third-party monitoring interface.

    Sources: 5, 6

  • Security

    Company sources Very limited public security evidence in the retained sources.

    Full note and sources

    Logger configuration and controlled protocol-document access do not establish authenticated transport, device access controls or cybersecurity certification.

    Sources: 7, 8

  • Quality

    Company sources Dated model-specific manuals, operating limits and two manufacturer-reported commercial examples provide maturity signals; independent field performance has not been established.

    Sources: 5, 6

  • Transparency

    Company sources Corporate identity and product manuals are public, while current detailed Modbus access has an approval boundary.
