Frequently Asked Questions

1. What is the benefit of a Pure Sine Wave inverter for home use?
A pure sine wave inverter provides clean and stable electricity, identical to the power from the grid. This ensures that sensitive appliances like refrigerators, microwave ovens, and computers run smoothly without interference or damage.
2. How many cycles can the LiFePO4 battery handle?
The high-quality A-grade Lithium (LiFePO4) battery used in this system offers a cycle life of up to 4000 times, providing much longer longevity compared to traditional lead-acid batteries.
3. Can I charge the system using a wall outlet and solar panels simultaneously?
Yes, this hybrid system supports charging via both Solar PV and AC power (mains supply), allowing for flexible energy management based on weather conditions.
4. What kind of solar controller is built into the system?
The system features an integrated 30A MPPT (Maximum Power Point Tracking) solar charge controller, which ensures over 97% charging efficiency from your solar panels.
5. Is the system protected against extreme weather?
The system is designed to operate in temperatures ranging from -25°C to +50°C and includes intelligent temperature-controlled fan cooling to prevent overheating during heavy use.
6. Does the unit support DC devices directly?
Yes, it includes 12VDC output ports and 5VDC USB ports, allowing you to charge mobile phones or power small DC appliances without using the AC inverter.
