l Directly connected to the solar panels (do not need to connect the battery)
Using precise 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.
l 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.
l 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.
l Pure Sine Wave Output
Use SPWM directly to make pure sine wave output.
l Automatic Sensing Function Solar Luminosity
Use the latest luminosity perception operation technology. The different illuminate angle and intensity of the solar panel will produce different current output. Use advanced CPU to operate the different illuminance and the data can be directly displayed on the LCD. Then you can visually see the sense of the strength of the sun unit. Used more convenient.
l 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 product automatically powers locked in maximum power point, then made the output power more stable.
l 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.
l Automatically Adapt To Different Load Power Factor
Adapt to any of the power load.
l Constant Current, Constant Power
This product is constant current, constant output power, without any overload, over-current phenomenon.
l 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.
l Current Limit Protection
l Stack Multiple Machines
Multiple small power inverters in parallel can achieve large output power.
l High-Frequency High Conversion Rate
Adapt high frequency converter, the output more efficient.

1、Please read the below notes carefully before installation.
A) Make sure the open voltage and operation voltage is in the range of 10.5-28V, and we recommend the 18V rated voltage solar panel or 24V battery.
B) Make sure the inverter’s AC voltage and frequency is the same with power grid voltage and frequency.
C) Installation inverter in the low humidity and well-ventilated place to avoid the inverter damp and overheating, And clear the inflammable and explosive materials around.
D) Recommended to use 4AWG DC input cable that can handle more than 50A current.
E) DC input cable no more than 8M, because long DC cable will reduce the voltage from solar panel to inverter, then make some loss.
F) There must be a circuit breaker between solar power generation and power grid(show like the “control switch” in figure 1). And there will be no load before the circuit breaker.
G) Before connect all the connections, you must disconnect the utility power. After make sure the all connections are right then connect the utility power.
H) If you need to disconnect the mains switch when the solar power generation is in operation, you
must disconnect the control switch first(show like the “control switch” in figure 1).
I) Avoid children touch or play the inverters, in order to prevent electric shock.
J) Non-professional do not disassemble the inverter, only qualified serviceman can repair it.
2、Connection DC terminal
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 bad contact.
