Product Description
300W ac dc solar power inverter (JYM-300W )
1,Q:Why your quotation is higher than other suppliers?
A:In domestic market, the high and low inverter brands are mixed together. There are many
low-cost solar power inverter is actually some assembled small unlicensed workshops, it crudely,
to reduce costs and use of substandard components for assembly, there is a very big security risk!
In order to protect the pro personal and property safety, please do not covet low
price, be sure to choose a reliable inverter!
..............................................................................................................................................................
2,Q:How many categories does it have according to the output waveform ?
A:Type one: JYM Modified Sine Wave inverter, which uses PWM pulse width modulation to generate
modified sine wave. Due to the usage of intelligent dedicated circuit and high power field effect tube,
it greatly reduces the power loss and increases the soft-start function, effectively ensuring the
reliability of the inverter. If the power quality is not highly demanded, it is able to meet the needs of
most electrical equipment. But it still exists 20% harmonic distortion problems when running
sophisticated equipment, can also cause high-frequency interference to radio communications
equipment. This kind of inverter can meet the basic needs of most of our power, high efficiency,
small noise, moderate price, and thus become the mainstream products in the market.
B:Type two: JYP Pure Sine Wave inverter, which adopts isolated coupling circuit design, high
efficiency, high stability of the output waveform, high-frequency technology, small in size, suitable for
all kinds of load, can be connected to any common electrical devices and inductive load devices
(such as refrigerators, electric drill, etc.) without any interference (eg: buzz and TV noise). The output
of pure sine wave inverter is the same as the grid tie power we daily used, or even better, because it
does not exist grid tie electromagnetic pollution.
..............................................................................................................................................................
3,Q:Is the output voltage of our inverter stable ?
A:Absolutely. Our inverter is designed with a good regulator circuit. You can even check it when
measuring the true value by a multimeter. Actually the output voltage is quite stable. Here we need
make a especial explanation : many customers found it is unstable when using conventional
multimeter to measure voltage. We can say the operation is incorrect. Ordinary multimeter can only
test pure sine waveform and calculate datas.
..............................................................................................................................................................
4,Q:What is a resistive load appliances?
A:Generally speaking, appliances like mobile phones, computers, LCD TVs, incandescents, electric
fans, video broadcast, small printers, electric mahjong machines, rice cookers etc. All belong to
resistive loads. Our modified sine wave solar power inverters can drive them successfully.
..............................................................................................................................................................
5,Q:What is the inductive load appliances?
A:It refers to the application of electromagnetic induction's principle, produced by high-power
electrical products, such as motor type, compressors, relays, fluorescent lamps, electric stove,
refrigerator, air conditioner, energy saving lamps, pumps, etc. These products'power are far more
than the rated power (about 3-7 times) when start. only pure sine wave inverter is available to them.
..............................................................................................................................................................
6,Q:What should be noticed when installing inverter?
A:Put the product in a place where is well ventilate,cool, dry and water-proof. Pls do not stress and
do not put foreign objects into the inverter.Rember turn on the inverter before turn on the appliance.
