Active Cooling for SolaX X3 Hybrid G4 Inverters
Looking for effective SolaX inverter cooling? Explore our active cooling kits designed for SolaX X3 Hybrid G4 5–15 kW solar inverters and compatible DRAŽICE IN.HYBRID COMPACT 5–15 kW models. Each cooling system features three Sunon fans, a 24V DC power supply and a mounting design adapted to the inverter's cooling fins.
Choose a cooling kit with a thermostat for automatic temperature-based fan control, or a version without a thermostat for external switching. Active airflow helps dissipate heat and reduce inverter operating temperatures.
Active Cooling for SolaX X3 Hybrid G4 Solar Inverters
SolaX solar inverters generate heat during operation, especially during periods of high electricity production and elevated ambient temperatures. Active cooling for SolaX X3 Hybrid G4 improves airflow around the inverter's cooling fins and helps dissipate heat.
Depending on installation and operating conditions, active cooling can reduce inverter operating temperatures by approximately 15–30°C. Actual results depend on ambient temperature, inverter load, installation location and airflow. Lower operating temperatures may help reduce thermal stress on electronic components and limit temperature-related power derating.
Which Inverters Are Compatible?
The cooling systems in this category are designed for the following inverter series:
- SolaX X3 Hybrid G4 5–15 kW: Hybrid solar inverters from the G4 generation.
- DRAŽICE IN.HYBRID COMPACT 5–15 kW: Compatible hybrid inverters with a corresponding cooling-fin design.
Before ordering, check the exact model designation of your inverter and the available installation space. Compatibility with other SolaX inverter generations should not be assumed automatically.
SolaX Cooling With or Without a Thermostat?
We offer two versions of active cooling, depending on how you want to control the fans.
- SolaX X3 Hybrid G4 Cooling Kit With Thermostat : The fans switch on and off automatically according to the temperature measured by an external sensor. The standard thermostat settings are ON at 40°C and OFF at 35°C.
- SolaX X3 Hybrid G4 Cooling Kit Without Thermostat : Designed for customers who prefer external fan control, such as a suitable automation system, smart plug or timer.
If you want automatic operation without setting up your own fan control, the thermostat version is the more convenient option. If you already have a suitable external control system, the version without a thermostat may be preferable.
Sunon Fans and Technical Specifications
Our SolaX cooling kits use three Sunon 60 mm fans with Vapo (MagLev) technology to provide active airflow around the inverter's cooling fins.
- Number of fans: 3 × Sunon 60 mm
- Fan technology: Vapo (MagLev)
- Total airflow: 138 m³/h
- Fan noise level: Approximately 31 dBA
- Operating voltage: 24V DC
- Power connector: 5.5 × 2.1 mm
- Power consumption during operation: Approximately 7 W
- Thermostat settings: ON at 40°C, OFF at 35°C (thermostat version only)
A compatible 24V DC power supply is included with the cooling kit. Please refer to the individual product pages for exact package contents and detailed specifications.
Easy Installation Without Modifying the Inverter
The cooling system is designed for external installation onto the inverter's cooling fins. Its mounting frame is secured in position without opening the inverter housing or modifying its internal electronics.
For the thermostat version, the temperature sensor is positioned on the specified area of the inverter's cooling fins. During installation, it is important to maintain sufficient space for airflow and follow the instructions supplied with the cooling kit.
Always observe the inverter manufacturer's installation and ventilation requirements.
Why Use Active Cooling for a Solar Inverter?
During hot weather or periods of high output, effective heat dissipation can be important for inverter operation. Active cooling uses forced airflow to help remove heat from the inverter's cooling surfaces.
- Helps reduce inverter operating temperatures during periods of higher load.
- May reduce thermal stress on electronic components.
- May help limit temperature-related power derating.
- Offers automatic temperature-based fan control when equipped with a thermostat.
Active cooling does not replace proper inverter placement, adequate ventilation or compliance with the manufacturer's operating requirements.
Frequently Asked Questions About SolaX Cooling
Is this cooling system suitable for all SolaX inverters?
No. The products in this category are intended for compatible SolaX X3 Hybrid G4 5–15 kW and DRAŽICE IN.HYBRID COMPACT 5–15 kW inverters. Compatibility with other inverter series must be checked separately.
How does the thermostat version work?
An external temperature sensor measures the temperature of the inverter's cooling fins. With the standard settings, the thermostat switches the fans on at 40°C and off when the temperature falls to 35°C.
How much can active cooling reduce inverter temperature?
Depending on operating and installation conditions, the reduction can be approximately 15–30°C. This is an indicative range rather than a guaranteed result for every installation.
Does installation require modifying the inverter?
The cooling system is designed for external mounting onto the inverter's cooling fins, without modifying the internal electronics. Always follow the relevant installation instructions.
What is the difference between the thermostat and non-thermostat versions?
The thermostat version controls the fans automatically according to temperature. The version without a thermostat requires a separate method of switching or controlling the power supply.
