1200w grid tie inverter - 110V Grid tie power inverter - DC AC Power Inverter & grid tie inverter

A. SURGE PROTECTOR:
sometimes, if you are using some heaving appliance like motor, enginee, cause the voltage up down very fast,in this moment, big amp will come into the grid inverter, easy to cause the ac mos burned, so surge protector will cut down by itself to protect the grid inverter.

B. lightning protection:
you may have experience, when meet the big lightning, the power source of the home appliance may damage,same reason, will also cause the inverter damage, in this moment the lightining protection can release thousand voltage to protect the inverter not damage.

C. HIGH SPEED AC FUSE:
now we put ac fuse outside, each inverter will come our special ac fuse, this will be broken 1mini/sec, to make sure high voltage spike come in!

1.idea for power jack

The inverter can be connected to any outlet at home, when this line run by the
conventional electric network. The inverter IC will monitors the volume,
frequency and phase of the home grid, then produce a pure sine wave that the
frequency and phase will be match the grid's, and the volume will be higher than
the grid's, then according to our current controlled PWM, to control the output
power to the grid. The inverter will puts out power when the home grid is on.

2. why use power jack grid tie inverter?

when you use solar panel through grid tie inverter, your home power meter will
reduce the speed(if you are using other electric appliances), or your home power
meter will backward(if you are not use any appliances)

3. difference of power jack grid tie inverter

traditional grid tie inverter is the solar panel are connect in series, so if
one solar panel did not work or bad efficiency, then the whole system will be
effects, but power jack grid tie inverter, you can use every inverter in
parallel, in this moment, each inverter has it's own MPPT, can make every solar
panel got the max power.

4. island protection

power jack grid tie inverter has 3greens light, when the charge fucntion is
normal, then this 3lights will turn on, but if there are not dc sources(like in
the night, no sun shine or raining day), the red led light will turn on, the
inverter will stop to work, in this moment, the inverter will close the door,
the home grid power will not back to inverter.
