Q1 What is the difference between the pure sine wave inverter and modified sine wave inverter?
A.Pure sine wave inverter adopts isolation coupling circuit design, high efficiency, strong sine wave high frequency technology,small size, output current is even better and stable than the mains grid, suitable for various load operation, can be connected to common Electrical products, digital equipment and other loads (such as mobile phones, computers, air conditioners,refrigerators,water pumps, etc.) without any interference.
B.The modified wave inverter adopts the PWM pulse width modulation method to produce the modified wave output. Under the condition that the quality of electricity is not high, it can meet the needs of most electrical equipment, but it has high harmonic distortion and is precise in operation. The equipment and communication equipment may cause travel problems, and it is difficult
to start the inductive load with high starting current.
Q2: Is our inverter output voltage stable?
A: The inverter voltage is about 220V±3%, which is different from many other inverters on the market when the output voltage
drops rapidly when the output is loaded.Greatly affect the operating state of the load. new energy inverters can still stabilize
at 220V voltage output when running at full load, ensuring the safety of users.
Q3: What is the perceptual load?
A: Inductive loads mainly refer to loads such as motors, compressors, fluorescent lamps, energy-saving lamps, induction
cookers,refrigerators, air conditioners, water pumps, etc. These types of loads will have an instantaneous power of 3 to 7 times
the rated power when they are started, and a pure sine wave inverse is required. Changer.
Q4: What is the impedance load?
A: Resistive loads are mainly mobile phones, computers, LCD TVs, incandescent lamps, electric fans, small printers, electric
mahjong machines, water dispensers, rice cookers and other electrical appliances. Modified wave inverters can also be used.
Q5: What should we pay attention when we use the inverter?
A.The positive and negative poles of the battery should be correctly connected to the B.positive and negative poles of the
inverter. Reverse connection may damage the inverter. C.Do not overload the output terminal with a load The storage environment of
the inverter needs to be ventilated and moisture-proof
Q6: How to calculate the inverter working hours?
A.The use time of the inverter depends on the battery power and the power of the load. B.You can refer to the following formula:
Working time = DC voltage x battery capacity x08 (battery discharge rate) x09 (inverter conversion efficiency) + load power
C.For example: 1 pcs 12V100AH battery drives 1 pcs 100W motor through the inverter Working time=12Vx100AHx08x0.9-100W=8.64 hours
