HeliosII 5kw solar system with battery backup

The HeliosII 5kw solar system with battery backup inverter has the ability to get 2880W solar panel energy to charge the battery or direct to load, continuous power 5000 watts, and 15,000 watts surge power suitable for any sensitive load. A friendly LCD human-computer LCD provides all the information for your off-grid solar system. CNBOU 10 years Professional manufacturer of inverters.


In our eyes, every detail of the HeliosII 5kw off-grid solar inverter is to improve quality, design and human-interactive, requirements, ensuring that your off-grid system can meet each of your needs when it is running, and it all comes from the 4.3-inch interactive LCD screen. On the screen, all the conditions of your off-grid solar system are readily apparent, including the voltage for your solar module, the inverter temperature, voltage, and capacity of the battery, charging current of the MPPT, whether the grid and inverter system output is normal, the day’s power generation, total power generation, PV power, load power, the most important for inverter priority.

After entering the settings interface, like Columbus on the edge of the New World, HeliosⅡoff grid solar inverter offers users many choices, including the temperature unit, AC output frequency, LCD backlight, grid charging capability, Alarm capability, and more.

The most important is CNBOU’s original, two AC output modes: Hold Vol and Hold Wave. The off-grid solar inverter has a voltage regulation function for, when the load resistance is at its highest, the Hold Vol is a good choice; when your maximum load needs high-quality AC power, the Hold Wave is a good choice.

No matter the circumstances, the HeliosII 0ff grid solar inverter always maintains a good output waveform. HeliosII supports 4 battery types: AGM/GEL/OPzV, LifePO4-15S, LifePO4-16S, LiMn2O4. In addition to our default battery full-voltage battery and empty-voltage value battery, users also can modify parameters to suit the battery pack, which means that all types of batteries can be compatible.
Of course, HeliosII-485MCP 5kw off-grid solar inverter also supports a variety of priority modes: Grid priority, Solar priority, Light priority, Time priority, Peak-filling mode, or a flexible working model can meet a user's needs.

5. Before packing, all functions are checked.

1. In order to prevent accidents and ensure safe and proper use of the product, please read precautions and use this equipment according to the instruction.
2. It is suggested to install a suitable fuse or breaker outside of the HeliosII off-grid solar inverter.
3. Before installing and adjusting the controller wiring, please break the connecting wire of the solar panel and battery, the fuse, or the breaker close to the battery terminal.
4. Non-professional operators please don’t open the HeliosII off-grid solar inverter, because of the high voltage inside the inverter. When open by yourself without warranty.
