As more C&I facilities adopt PV plus storage, the choice of a hybrid inverter company becomes a strategic decision. Hybrid inverters and energy
storage systems sit at the core of on-site energy management, connecting PV arrays, batteries, loads, and the grid. A suitable partner should
combine strong technology, reliable products, and practical experience in C&I scenarios.
-
Understanding Hybrid Inverters in C&I Applications
Hybrid inverters for C&I applications are typically three-phase units that coordinate:
-
PV input and MPPT control
-
Battery charging and discharging
-
AC power flow to and from the grid
-
Backup supply to selected loads during outages
They may operate as part of a broader system that includes modular battery banks, metering devices, and energy management platforms.
For C&I users, such systems can support peak shaving, backup power, and improved visibility of energy flows.

Evaluating Company Background and R&D Strength
A strong hybrid inverter company is built on solid foundations.
AUXSOL, a subsidiary of Sanxing Electric Ningbo, under AUX Group (est. 1986), benefits from decades of experience in electrical equipment
and other industries. AUX Group has multiple business segments and listed companies, providing a robust base for ongoing investment in
new energy technologies.
AUXSOL operates R&D centers and testing facilities that focus on power electronics, control, and system integration for PV and energy storage.
This enables continuous improvement in product performance and reliability.
Certification to ISO 9001, ISO 14001, and ISO 45001 demonstrates a structured approach to quality, environmental management, and
occupational health and safety.
These aspects give C&I customers confidence that the company can support long-term projects.
-
Product Portfolio and C&I Focus
A professional hybrid inverter company should offer a portfolio that covers key C&I needs.
AUXSOL provides three-phase hybrid inverters in the 5–20 kW range, suitable for small commercial and light industrial users who want to
integrate PV and storage and support backup operation.
For larger plants, AUXSOL offers a broad range of three-phase on-grid inverters from 5–25 kW, 30–40 kW, 50–80 kW, and 70–110 kW, as
well as 250–350 kW high-voltage models.
These products can be combined with energy storage solutions where appropriate.
AUXSOL’s portfolio includes modular LFP battery packs in both low-voltage and high-voltage versions, along with larger containerized
energy storage systems, which can be paired with hybrid inverters or connected to AC-coupled configurations.
A unified portfolio simplifies system integration and technical support for C&I customers.

Technical Features Relevant to C&I Users
Hybrid inverters require features that support demanding C&I operations.
AUXSOL three-phase inverters achieve maximum efficiencies up to about 98.6% and support DC oversizing, helping to improve the energy
yield and flexibility in system design.
High string current capability and wide MPPT voltage ranges allow the use of large-format modules and varied string configurations, supporting
roof and ground-mounted C&I layouts.
Integrated AFCI, DC/AC surge protection, insulation monitoring, and string-level monitoring help safeguard C&I installations and support efficient
operation and maintenance.
These capabilities are important in projects where uptime and predictable performance are essential.
-
Certifications and Grid Code Compliance
C&I projects frequently involve stringent grid requirements and safety standards.
AUXSOL inverter products are certified to standards such as EN 50549-1, IEC 61727, IEC 62116, IEC 61683, VDE-AR-N 4105, and others, along with
region-specific certifications where applicable.
This range of certifications allows hybrid and on-grid inverters to be deployed in different regions while meeting local grid codes, easing approval
processes and reducing engineering risk.
When selecting a supplier, checking up-to-date certificates for the target country is an important step.
-
Service Network and Project Support
For C&I users, strong service and support capabilities are particularly valuable.
AUXSOL is building a global marketing and service system for PV products, with customer service centers in Brazil, Germany, and Poland, among
other locations. This helps provide local or regional support for installation partners and end customers.
Remote monitoring, diagnostics, and firmware updates support faster issue resolution and smoother long-term operation.
While AUXSOL focuses on product development and support, local EPCs and installers perform detailed system design and on-site work, combining
global product expertise with local project experience.
This combination helps C&I projects move from concept to operation more smoothly.

Practical Steps When Choosing a Supplier
When selecting an industrial hybrid inverter company for your C&I project:
-
Define your application scenario and main objectives (peak shaving, backup, self-consumption, or a combination).
-
Check that the supplier’s hybrid and on-grid inverters cover your required power range and grid voltage.
-
Confirm that batteries and EMS solutions are available and compatible with your intended use.
-
Review certifications for the target country and grid code.
-
Evaluate service presence and response capabilities in or near your region.
By following these steps, C&I investors can identify suppliers whose solutions closely match project requirements.
If you share the approximate size and location of your C&I projects, more specific product ranges and configuration directions could be suggested.
