DC10.5V-30V to AC110/120V 300W micro inverter for 18V solar panel
System Function
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.
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.
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 current, 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-Frequency High Conversion Rate
Adapt high frequency converter, the output more efficient.
