Low Frequency Off grid solar inverter is a combination of Solar inverter , AC charger and MPPT Solar Controller. it can draw power from both solar panel and grid to supply electricity to load.
LF inverters are characterized by their robust build, using larger transformers and operating at a lower frequency. They are well-suited for larger installations and environments with fluctuating power supply.
Low Frequency inverter advantage is : 1. Durability 2. Can Large Electrical Load . 3. Stable Performance in unstable grid connections. 4. Heat Resistance,operate efficiently in higher temperatures.

Sunflx Low Frequency Off grid solar inverter is a combination of Solar inverter , AC charger and MPPT Solar Controller. it can draw power from both solar panel and grid to supply electricity to load.
Function converting the Direct Current (DC) from solar panels into Alternating Current (AC), the form of electricity used in most homes and businesses
LF inverters are characterized by their robust build, using larger transformers and operating at a lower frequency. They are well-suited for larger installations and environments with fluctuating power supply.
Low Frequency inverter advantage is :
Off grid solar power system is when your solar panel remains connected to the grid and also has a backup battery system to store power produced by the solar panel. Off grid solar power System includes: Solar Panel, off-grid solar inverter, Backup battery, and accessories.
• In the daytime, the solar panel will generate electricity for household load, at this time, inverter will charge the battery .
• In the Night, The inverter will take power from the battery to supply household appliances. When the battery power is low, the Grid will continue to supply electricity to the load from inverter bypass circuit. and at this time you can also choose to charge the battery from Grid through the inverter.
You can understand the Main Difference from the below Four points :
For more detail explanation , Please Read this Articte
Application Areas:
Remote Locations: Ideal for areas without grid access or with frequent power outages. Like Rural Homes and Farms ,Mountain Cabins and Retreats,Island houses ,Eco-Tourism Facilities,Mobile Clinics and Schools,Outdoor Recreational Activities etc.
Residential/Commercial Use: Suitable for homes or businesses needing a reliable power source.
Application Load:
Below Loads are suggested to use Low-Frequency Solar Inverters instead of High-Frequency ones:
Below is main components of a low Frequency off grid solar inverter :
– Assess Your Load: Calculate the total wattage of all the devices and appliances you plan to power. Include items like lights, refrigerators, TVs, and any other electrical equipment.
– Consider Peak Load: Some appliances, like refrigerators or pumps, have higher start-up power requirements. Ensure the inverter can handle these peak loads.
– Match with Solar Panels: Your inverter should be compatible with voltage and Current characteristics of your solar panel array. for example your solar array Voc votlage is 120V, then you will need an inverter with Max PV input over 120V ,then can work with your solar array.
– Consider Future Expansion: If you plan to add more panels later, choose an inverter that can accommodate this. For example right now you only have 5 solar panel total 1500W. and maybe in the future you will think about to increase them to 3000W. so you would better choose a inverter which Max PV input power 3000W from the very beginning.
– Voltage Compatibility: Ensure the inverter matches the voltage of your battery system (12V, 24V, 48V, etc.).
– Battery Type: Some inverters are better suited for certain types of batteries (like lead-acid or lithium-ion). Check compatibility. Sunflx inverter can work perfectly with lead-acid and lithium-ion. So this will not need to worry.
– High Conversion Efficiency: Look for inverters with a high efficiency rating (usually above 90%). Sunflx inverter convert efficiency is from 92%-95%. Performance above Standard !
– Maximum Power Point Tracking (MPPT): MPPT technology maximizes the power extraction from solar panels, especially under varying light conditions. Sunflx All inverter are equip with MPPT solar charger with 98% charging efficiency .
– Temperature Tolerance: Check the operating temperature range, especially if you live in a very hot or cold climate.
– Protection Features: Look for inverters with protection against overloads, short circuits, and over-temperature.
– Size and Weight: Ensure the inverter’s physical dimensions fit your installation space.
– Ease of Installation: User-friendly installation and setup are important, especially if you plan to do it yourself.
– Maintenance Requirements: Consider how easy it is to maintain and service the inverter.
– Remote Monitoring: Some inverters offer the ability to monitor performance remotely, which can be a handy feature.
– Expand ability: If you might expand your system in the future, choose an inverter that can grow with your needs.
– Cost: Balance your budget with the features and reliability you need.
– Warranty and Support: Look for a product with a good warranty and accessible customer support.
Safety and Quality Certifications: Ensure the inverter meets relevant international safety and performance standards.
Manufacturer Reliability: Research the brand’s reputation for quality and service.

I started business with Sunflx for two years. at first i brought two MPPT solar controller from them , their price is good and turned out the products is is satisfactory. later we start inverter orders ,they reply question are fast , Easy to work them.
I bought Sunflx solar inverter for my own shop , it is good quality , Here in my city have many brands solar inverter , But not every brands have good quality ,they use 1 year and then not working . so far Sunflx solar inverter works well without any problem ,No customer return back to me.
