1. grid tie inverter is designed for small solar panel & wind energy market, it's suitable for family enengy system.
2. this inverter can directly use solar panel, wind charger through inverter to home grid.
3. easy to installation, just need solar panel, grid tie inverter, then directly can put into home grid.
1200 watt grid tie inverter. This unit is pretty good, at 800 watts output it runs cool. Much larger then the unit advertised (appears as their 2000w unit), which is a good thing. Seems they are improving these from the previous versions. The 600w unit is in the backround for size comparison.
I got so excited when I read that you can buy a plug-and-play grid tie inverter and pump the electricity from your solar panel directly into the grid for less than a hundred bucks that I snatched up the first one I saw on ebay.
The problem with the dream is that utilities require you to jump through such a series of hoops before tying into the grid that you might as well not even think about it unless you're willing to sink a few thousand dollars into the project. I contacted our local electric company (Appalachian Electric Power) and found out that in order to plug in a grid tie inverter, we'd need to:
Many people buy these plug-and-play grid tie inverter surreptitiously put them to use in their own homes. Chances are, no one at the electric company would ever find out (although if you go the illegal route and have a fire in your home, your fire insurance will probably refuse to pay for the damages.

WHAT'S NEW
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 tie 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 h ave 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!
ADVANTAGE
1. pay 600w’s cost but you are buying a 1200w grid tie inverter.
2. with big cooling alumni housing, it is rather easy to cool down the machine.
3. with big size transformer inside, to make sure you enjoy high efficiency.
4. with big Mos-Fet inside, to prolong machine life,
With big cooling alumni housing, it is so easy to dissipate heat that most of the time the equipment will work normally without turning the fan on. That's the point-- you already do so much to get green power, why spend the power to run the fan?
Normal working temper of Mos-fet is between 68℉ to 102℉. After 8 hours’ duration, it will be over 102℉ in most normal design inverter. In that case, the efficiency will decrease to 80%, then 70% or even 60%. If you take this big guy home, what will happen? It is similar to involve Corby Brian to play the junior high school basketball game and of course he can get the MVP all the time! Power Jack is not famous brand in USA, but we are working very hard and improving every day for each details to bring customer better quality equipment and happier shopping experience.
According to our market experience, if your solar panel is 500w-600w, a single 600w grid tie inverter is not enough, because of continuous using, the temperature will be high.
1. in this moment, the grid tie will be very easy to get temperature protection, will take 5-10secs before restarting,
2. in this moment, the fan will be turn on automatically, it's also waste your solar panel power.
3. if you use 1200w grid tie inverter(for 600w solar panel), no matter 1pc 1200w or 4pcs 300w grid tie, the fan will not turn on very easy, and the equipment will not go to temperature protection so easily, either.
A big amount of energy can be saved in a whole year use in this case comparing to using a single 600w one.
FEATURE
(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 whose frequency and phase matches the grid's and the volume is higher than the grid's, then output power to the grid according to control -PWM’s set.
The inverter will output power when the home grid is on.
(2). why use power jack grid tie inverter?
When using solar panel through grid tie inverter, your home power meter will reduce the speed (if you are using other electric appliances), or move backward (if you are not use any appliances)
(3). advantage of power jack grid tie inverter
When using traditional grid tie inverter, solar panels would be connected in series. If one solar panel does not work nor has bad efficiency, the whole system would be affected. When using power jack grid tie inverter, you can use several inverters in parallel. Each inverter has its own MPPT and will work singly to ensure that every solar panel get the max power.
(4). island protection
Power jack grid tie inverter has three greens lights. When the charge function is normal, all green lights will turn on. But the red led light will turn on if there are no dc sources (like at night, cloudy or raining day), then the inverter will stop working. In that case, the inverter will close the door and the home grid power will not back to the inverter.
