The CIT 5–25kW On-Grid Solar Inverter is a high-performance grid-tied inverter designed to deliver efficient, reliable, and stable solar power conversion for residential, commercial, and demanding outdoor installations.
With a wide 140–1000V MPPT voltage range, dual MPPT technology, high PV input current of up to 16A/32A, and a flexible 1+2 string configuration, the CIT series provides greater flexibility when designing photovoltaic systems with different roof orientations, module configurations, and installation conditions.
Built for long-term outdoor operation, the inverter features IP66 protection, a -25°C to 60°C operating temperature range, fanless cooling, and a 10-year warranty. Its compact, low-noise design makes it suitable for installations where reliability and quiet operation are important.

Key Features

Wide 140–1000V MPPT Voltage Range
The CIT inverter provides a wide MPPT operating voltage range of 140V to 1000V, allowing the photovoltaic system to maintain stable operation across a broad range of solar conditions.
The wide voltage range helps the inverter continue tracking available solar energy during varying operating conditions, including lower-light periods and high-temperature environments.

Dual MPPT Technology
The dual MPPT (Maximum Power Point Tracking) architecture enables the inverter to independently optimize power generation from different PV array configurations.
This is particularly useful for installations where solar panels are installed on:

Different roof orientations
Multiple roof sections
Arrays with different module configurations
Areas affected by different shading conditions

By independently tracking the connected PV arrays, the inverter can help reduce mismatch losses and improve overall system performance.

Flexible 1+2 String Configuration
The CIT series incorporates a flexible 1+2 string configuration, providing greater freedom when designing and connecting PV arrays.
Independent string optimization helps accommodate more complex solar installations while allowing different strings to operate according to their individual conditions.
This flexibility can simplify system design and help maximize the available solar generation from different PV array sections.
High PV Input Current — 16A / 32A
With 16A/32A high input current capability, the CIT inverter is designed to accommodate modern high-power and high-current photovoltaic modules.
Higher input-current compatibility provides greater flexibility when selecting today’s high-output solar panels and can help reduce the number of strings required in suitable system configurations.

Designed for Reliable Outdoor Operation

Solar inverters operate in challenging environments, often exposed to heat, dust, moisture, and changing weather conditions. The CIT 5–25kW inverter is designed with durability and dependable outdoor operation in mind.

IP66 Protection
The inverter features an IP66-rated enclosure, providing a high level of protection against dust and water ingress.
This makes the CIT series suitable for demanding outdoor solar installations where equipment may be exposed to harsh environmental conditions.
Wide Operating Temperature Range
The inverter is designed to operate from -25°C to 60°C, supporting reliable performance across a wide range of environmental conditions.
This makes it suitable for solar installations exposed to both cold and high-temperature environments.
Fanless Cooling for Quiet Operation
The CIT inverter uses a silent fanless cooling design, eliminating the need for conventional cooling fans.
This provides:

Quiet operation
Reduced moving parts
Lower maintenance requirements
Suitable operation in noise-sensitive environments

The fanless design also contributes to the inverter’s compact and streamlined construction.

Smart Monitoring & Communication

The CIT series supports WiFi and RS485 communication, enabling convenient system monitoring and management.
Users can monitor important system information and inverter operating status through supported communication and monitoring solutions.
Remote Monitoring
Remote monitoring provides greater visibility into the solar system’s operation and makes it easier to identify system conditions without requiring frequent physical inspection.
This can help improve:

System management
Operational convenience
Performance monitoring
Maintenance response
