500W Solar Grid TIe Inverter Can Work With No Battery 10.5-30V DC Input 110V 120V or 220V 230V AC Output
Features:
Directly connected to the solar panels (do not need to connect the battery)
Using precise Dynamic differential pressure type MPPT function, APL functions, the inverter automatically adjust the solar panels of maximum output power, simply connect the solar panel to the grid inverters. Do not need to connect the battery.
AC 0 angle with high precision auto-detection
AC phase angle of 0 through isolation amplifier then input to the MCU for high-precision detection and analysis. The phase shift rate is less than 1%, thus achieve high-precision with phase modulation AC output together.
Synchronous High-frequency Modulation
In the process of the grid, usually adapt the same phase angle in parallel. (ie, When the two-phase alternating current total is equal to 0. Use switch to combination the two AC fusion) and the product is rectified AC half-frequency AC to 100Hz first, then the machine use the high frequency current in the circuit and semi-100Hz frequency alternating current generated combination, to achieve high-frequency modulation.
Pure Sine Wave Output
Use SPWM directly to make pure sine wave output.
Power Automatically Locked (APL)
In different current fluctuations, we should use the MPPT function. When the MPPT function adjusted to the maximum power point, the porduct automatically powers locked in maximum power point, then made the output power more stable.
Maximum Power Point Tracking (MPPT)
Because the current intensity and the voltage changes at any time, if there is no power point tracking, there will be a lot of problems. In the past time, usually adopt a solar controller, but this product uses high-precision MPPT operation power, automatic and immediate adjust the solar panels output power at the maximum output point, then achieve a stable output purposes.
Automatically Adapt To Different Load Power Factor
Adapt to any of the power load.
Constant Current, Constant Power
This product is constant currrent, constant output power, without any overload, over-current phenomenon.
Automatically Shut Down When The Power Output Of a Fault
When the city power system is in failure, the inverter will automatically turn off the output.
Current Limit Protection
Current limit
Stack Multiple Machines
Multiple small power inverters in parallel can achieve large output power.
High- Frenquency High Conversion Rate
Adapt high frequency converter, the output more efficient.

How to Connect it?
Product Details
Connect the solar panels positive terminal to inverter's positive terminal,and negative to negative.And you must screw up the nut to avoid the had contact.Show in 3
Connection of AC terminal
Before connect the inverters AC cable tothe socket, you must disconnect the utilitypower. Then put the AC cablewhich has holes terminal into the inverters 3 feet port and thepin terminal to the socket. Please make sureboth of the terminalare connect fastness toavoid bad contact. Show like 4

After all connection,the inverter's green LED shows, it means the inverter start to work.
Several or many inverters used in parallel.
In order to achieve higher power, we can usethis inverter in stack. For example:4 pcs of 300W grid tie inverter used in stackcanachieve 1200W.And the stacking number is unlimited.Show like the 5.
