500W Grid Tie Inverter DC20-50V AC110V MPPT Power Solar Inverter
500W Grid Tie Inverter DC20-50V AC110V MPPT Power Solar Inverter by BBGS at Solar Kit 2010. Hurry! Limited time offer. Offer valid only while supplies last. System Functiondirectly connected to the solarpanels (do not need to connect the battery) Using precise Dynamic differential pressure type
directly connected to the solarpanels (do not need to connect the battery)
Using precise Dynamic differential pressure type MPPTfunction, APL functions, the inverter automatically adjust the solar panels ofmaximum output power,simply connect the solar panel to the grid inverters. Do not need toconnect the battery.
AC 0 angle with high precisionauto-detection
AC phaseangle of 0 through isolation amplifier then input to the MCU for high-precisiondetection and analysis. The phase shift rate is less than 1%, thus achievehigh-precision with phase modulation AC output together.
Synchronous High-frequency Modulation
In the process of the grid, usually adapt the same phaseangle in parallel.(ie, When the two-phase alternating current total is equal to0.Use switch to combination the two AC fusion) and the product is rectified AChalf-frequency AC to 100Hz first, then the machine use the high frequencycurrent in the circuit and semi-100Hz frequency alternating current generatedcombination, to achieve high-frequency modulation.
UseSPWM directly to make pure sine wave output.
PowerAutomatically Locked (APL)
Indifferent current fluctuations, we should use the MPPT function.When the MPPT functionadjusted to the maximum power point, the product automatically powers locked inmaximum power point, then made the output power more stable.
MaximumPower Point Tracking (MPPT)
Becausethe current intensity and the voltage changes at any time, if there is no powerpoint tracking, there will be a lot of problems. In the past time, usuallyadopt a solar controller, but this product uses high-precision MPPT operation power, automatic andimmediate adjust the solar panels output power at the maximum output point,then achieve a stable output purposes.
AutomaticallyAdapt To Different Load Power Factor
Adaptto any of the power load.
