Устройството е изпитвано дълго време при условия на изключително ниски температури и различна влажност на открито. Въз основа на този опит е разработен алгоритъм на работа чрез всички налични параметри, за да се постигане най-добрият ефект на размразяване на топлообменника. Това съкращава времето за размразяване и подобрява ефективността.
Термопомпите от SOL AIRPOWER имат най-висока степен на енергийна ефективност, т.е. A+++. Което означава, че устройствата отговарят на критериите за получаване на безвъзмездни средства от местното правителство.
В основата на цялата система за отопление на термопомпите от серията SOL AIRPOWER на Solplanet се намира компресорът на Panasonic, който е с технология EVI. Това е устройство с променлива скорост, което се адаптира към енергийна потребност в съответния момент. Благодарение на синусоидалното управление на постояннотоковия инвертор е постигната висока степен на ефективност върху широк работен диапазон и ниски нива на шум, така че комфортът при използване на устройството е на възможно най-високо ниво.
Системата EVI (Enhanced Vapor Injection) представлява допълнително впръскване на пара в главата на компресора, интегрирана с по-малък теплообменник, наречен икономизатор. Целта на тази система е да се увеличи ефективността на цялостната отоплителна система при ниски температури чрез преохлаждане на хладилния агент и използване на допълнително впръскване на студена пара. Увеличаването на ефективността на термопомпа чрез технологията EVI може да достигне до 30%.
Smart defrost in heat pumps refers to an intelligent and automated defrosting process designed to enhance the system’s efficiency during cold weather. Heat pumps can accumulate frost or ice on their outdoor coils, hindering performance. Smart defrost systems monitor various factors, such as temperature and humidity, and initiate defrost cycles when necessary. By optimizing the timing and duration of defrosting, smart defrost technology minimizes energy consumption, ensuring the heat pump operates at peak efficiency even in cold conditions. This feature contributes to improved overall performance and energy savings in heat pump systems.
The energy class of heat pumps can vary depending on the specific model and its energy efficiency rating. Heat pumps are typically rated on a scale from A+++ to D, with A+++ being the most energy-efficient and D being the least. The rating is based on the Coefficient of Performance (COP), which measures the efficiency of the heat pump in converting energy to heat. Higher COP values result in a higher energy efficiency rating and a better energy class.
SOL AIRPOWER heat pumps have the highest level of energy efficiency: A+++.
At the core of the Solplanet SOL AIRPOWER heat pump system lies a Panasonic compressor equipped with EVI technology. This device operates at variable rotational speed, adapting to the prevailing energy demand. The implementation of DC inverter sine wave control has resulted in remarkable efficiency across a broad operational range, maintaining a low noise level for optimal user comfort. This advanced technology ensures the system operates efficiently and quietly, delivering a superior level of comfort in its use.
EVI stands for Enhanced Vapor Injection and it is a technology that enhances the efficiency and performance of the heat pump, especially in colder climates.
In a heat pump, the refrigerant plays a crucial role in transferring heat. EVI technology involves injecting additional vapour into the compressor to increase its capacity and efficiency, allowing the heat pump to maintain satisfactory performance even at lower outdoor temperatures. This makes EVI-equipped heat pumps well-suited for heating applications in regions with colder climates, as they can extract heat from the air or ground more effectively in suboptimal conditions. The technology contributes to improved heating capacity and efficiency of up to 30%.

All of our inverters have some basic power management functions by default since they’re usually required by local power grid regulations.
You can increase the power management function with one of our data loggers. After the installation of a data logger, you can log in to our app, our web server, or our cloud service to set the active/reactive power value, the fixed power factor, or the reactive power curve to control power.
It is possible to send instructions to the inverter and control the power output in real time using a third-party control device like a radio ripple control receiver (RRCR) or a demand response enabling device (DRED) connected to AiComm.
For more details, please refer to the user manual for your specific inverter, or contact your local technical support team for guidance.
Solplanet has several data logging solutions suitable for use on a variety of PV installations.
If you have a residential installation, our Wi-Fi stick could be your perfect option. It installs on the bottom of the inverter housing using a quick plug-in connection and can support one inverter.
If your installation is larger, perhaps a commercial or industrial setup, your best option might be an AiComm. It too installs on the outside of the inverter housing, but it connects to a router via WiFi and can support up to five inverters.
Contact your local Solplanet team for assistance in choosing which data logger is right for you.
Yes, Solplanet inverters support third-party data loggers like Solarlog, Meteocontrol, and Solarman. For large-scale PV installations, we can offer our protocol to a third party to be used to develop their own customized monitoring solution.
No, the AISWEI Cloud does not obtain or record weather data like irradiation levels, temperature, or wind speed. If you need to monitor the weather to support your PV installation, you can either purchase an independent weather station or use a third-party solution (like Solarlog, Meteocontrol, and Solarman).
Yes, you can. However, because of outdoor weather conditions, an AiComm must be installed within an IP65-rated enclosure.
No, our inverters do not support local monitoring. Our monitoring solutions (either a GPRS stick, WiFi stick, or AiComm) upload inverter data to the Solplanet Cloud and that requires a stable and reliable internet connection. If required, we can supply our communications protocol to our customers so they can develop their own monitoring systems.
Your privacy is one of our top concerns and we take it very seriously. Once you permit us to collect your data, it will be stored in compliance with privacy laws in your country.
If you have concerns about how we collect and store your data, please don’t hesitate to contact your local Solplanet team.

Yes, it can. The PV array can typically be oversized by 150% depending on location and site irradiation levels. But note that excessive PV array oversizing can result in wasted money and a negative impact on the reliability of the inverter. If you have questions about oversizing a PV array, please contact your local Solplanet office.
Solplanet inverters can be used with thin-film solar panels, but this would be a pretty rare setup. Thin-film solar panels are usually better suited for portable devices. Solplanet inverters are stationary and are designed for traditional PV arrays in residential, commercial, and industrial situations.
However, some thin-film panels on the market do not have to be adhered to a surface and in these cases, a Solplanet inverter will operate correctly.
No, they cannot. Solplanet inverters are designed to be on-grid inverters. The AC side of the inverter should be connected to the utility grid at all times. There are no settings to allow the inverter to operate in an “off-the-grid” or “island” mode. Solplanet cannot guarantee correct operation in off-grid applications and will not warranty any damages caused to the inverter(s) or the PV plant caused by off-grid use.
Solplanet produces only non-isolated (transformerless) inverters. The transformerless inverter is the most common in the residential and commercial market because it usually has the highest efficiency, lowest cost, smallest size and lightest weight compared to isolated (transformer) inverters.
Yes, all Solplanet inverters are equipped with a DC switch for smooth and uninterrupted power distribution.
In the simplest of terms, you’ll want to match your inverter to the wattage of your PV array. For example, if you have a 3000-watt PV array, you’ll need a 3000-watt inverter at a minimum. You’ll also need to consider things like the rating of your PV array, the maximum size of the installation, and even your geographical location. But don’t worry, it’s not as complicated as it seems.
Contact our technical support team for help determining which Solplanet inverter is the best match for you.
Detailed installation instructions for each of our inverters can be found on each product page. You can also find installation instructions in the Downloads section of the Installer Area on our website.
If you see this error code, there are a few things you will need to check. First, verify that the fuse and the triggering of the circuit breaker in the distribution box are functioning properly. Second, check the grid voltage and grid usability. Third, check the AC cable and make sure the inverter is connected to the grid. If the fault persists after you’ve checked these three things, please contact your local technical support team for assistance.
Check the grid voltage at the connection point on the inverter.
