Off-grid and hybrid solar inverters for different power requirements
Our Solar Inverter range covers 1 kW to 30 kW rated power options, including Off-Grid Solar Inverters and Hybrid Solar Inverters. With pure sine wave output, multiple battery options, and single-phase and three-phase configurations, we offer products for different solar power system requirements.
Whether your project requires independent solar power, battery backup, or a combination of solar and utility power, our product range provides different configurations for system selection.
A focused power electronics product portfolio
Our product range includes Battery Chargers, Solar Inverters, MPPT Solar Charge Controllers, Voltage Stabilizers, and Transformers. This gives customers access to related power electronics products from one manufacturer.
In-house manufacturing facilities
Our 6,500 m² manufacturing facilities and 5 production lines provide an established production base for our product range.
Hardware and software R&D
Our hardware and software development teams support product development and the evaluation of electrical, functional, firmware, and mechanical customization requirements.
Related technical support
We provide system requirement assessment, configuration review, fault diagnosis, and technical support for relevant products.
Product types and key features
Off-Grid Solar Inverter
For independent solar power systems in locations where utility grid access is limited or unavailable. The inverter converts DC power into AC electricity for connected electrical loads.
Hybrid Solar Inverter
Combines solar power, battery storage, and utility power according to the selected configuration. This provides multiple power supply options for hybrid energy systems.
Pure sine wave output
Provides an AC waveform for resistive and selected inductive loads. For water pumps, motors, and other inductive loads, we recommend evaluating the motor power and starting current when selecting the inverter model.
Multiple operating modes
Our product range includes PV Solar Mode, Mains Supply Mode, and Energy-Saving Mode. Energy-Saving Mode is available on applicable models and helps reduce unnecessary battery discharge and standby power consumption under light-load conditions.

02
Battery backup systems
For energy systems incorporating battery storage as part of their power supply configuration.
03
Commercial and industrial power applications
For selected electrical loads requiring solar power conversion or hybrid power supply.
04
We offer standard product configurations and project-based engineering evaluation for specific technical requirements.
Electrical configuration
We can evaluate required input and output electrical configurations according to the intended system.
Operating functions
Specific operating functions and control requirements can be assessed for project applications.
Firmware modifications
We can evaluate firmware-related modifications according to the required operating logic.
Mechanical adjustments
Mechanical and enclosure requirements can be reviewed for projects requiring changes to the existing product design.
Engineering evaluation and sample validation
Customized requirements undergo engineering evaluation, with sample validation arranged as part of the project process.
Manufacturing and quality control
Our manufacturing facilities cover 6,500 m², with 5 production lines and a dedicated hardware and software R&D team.
The company's overall finished-product output is approximately 1,500 units per day across its broader product operations. This figure represents company-wide output, not Solar Inverter-specific production capacity.
Our manufacturing and quality control processes include:
Incoming Quality Control (IQC)
Inspection of incoming components and materials before production.
PCB and module assembly
Assembly of electronic boards and functional modules.
Complete unit assembly
Integration of components into finished products.
Functional testing
Testing product operation and electrical functions.
Aging testing
Testing products during the aging stage.
Final inspection
Final product checks before shipment.
