Frequently Asked Questions

Yes, but please ensure that the battery capacity can always support the inverter's energy supply.

Yes,it’s pure sine wave inverter ,which is pefect for a computer or a laptop.

It is not recommended to use the inverter to recharge the battery, which may damage the inverter

No,the inverters cannot be stacked in series or parallel

No ,the inverter is off grid only ,prohibit connection to mains

What you are seeing is normal .The tester you’re using is for use with household utility power ;the inverter is a standalone system, the internal wiring of the inverter causes this symptom.

During use, due to load or other factors, the output voltage may deviate from the normal use range.Pls kindly known that the output voltage can be reset in a certain range at your end .

The 24 volt input cannot be changed to 12 volts. This is the factory setting and involves a series of parts inside the inverter.

Choosing the right size of inverter depends on the power requirements of the appliances you expect to operate at any given time，including both the continuous and surge power rating of your appliance.

The continuous rating of the inverter must be high enough to handle all the loads that may run at the same time. The inverter must also be capable of handling the starting surge of all loads that may start at the same time.

Commonly used electrical appliances can usually be divided into resistive load and inductive load.

The inverter can work with most resistive
loads less than its continuous power，such as :laptops,phones, TVs, electric cookers,LED lights,fans,etc.

But for most inductive loads whose vast majority power consumption takes place in the compressor or motor, such as refrigerators,freezers ,microwaves,Water pumps, air conditioners ,power tools ,etc.

Their instantaneous power in startup phase is 6-7 times ,or even 10 times bigger as it’s working power .So we suggest  use 10 times higher power inverter for inductive loads

Runtime depends on your battery capacity, inverter efficiency, and the total wattage of the connected load. Higher-capacity batteries and lower power consumption will provide longer operating time.

The correct cable size depends on the inverter input voltage, current draw, and cable length. Using undersized cables can cause voltage drop, poor performance, and overheating.

Basic installations may be possible if you are familiar with DC wiring and safety requirements. For larger systems or home backup applications, professional installation is strongly recommended.

Install the inverter in a dry, well-ventilated location away from heat, moisture, direct sunlight, and flammable materials. Leave enough space around the unit for proper airflow.

It shows a voltage between the red line and the yellow line. There is also a voltage between the black line and the yellow line. They are virtual voltages and have no current. It is normal.

No,the inverter we provide is single-phased,just one input voltage and one output voltage ,it can't divide two lines of 110v that sum to 220v.It has only one output voltage 110vac or 220vac.

Yes. Many users run inverters while driving to power electronics and charge devices, as long as the vehicle electrical system can support the load safely.

Yes, if your system is properly sized and ventilated. However, leaving it on continuously will still consume battery power even when no load is connected.

Inverters generate heat during operation, especially under heavy load. High ambient temperature, poor ventilation, or overload can cause the unit to run hotter than normal.

This may happen because of low battery voltage, overload, overheating, or insufficient cable size. Check the battery condition, connected load, ventilation, and wiring.

Yes. Many inverters use temperature-controlled or load-controlled fans, so the fan may start and stop automatically during normal operation.

Check that the battery voltage is correct, the fuse or breaker is not open, the cable connections are secure, and the power switch is in the correct position.
