Product Description

Wholesale solar power system grid-connected micro inverter 

Product Description

• 400W micro inverter solar grid tie microinverter IP65 wifi control self cooling 120V/230V automatic identification power inverters,high frequency direct modulation and 6-grade power search design micro inverter
• Solar micro inverter which can directly connected solar panels (do not need to connect the battery),microinverter support wide solar power input(22-60VDC voltage, 400W solar power), output: 50Hz/60Hz(45Hz ~ 64Hz ), 400W 110VAC/230VAC
• 99.5% high efficiency grid tie inverter --maximum power point tracking(MPPT)---high-precision (MPPT)operation power automatic and immediate adjust the solar panels output power at the maximum output point,made the inverter discharge power with the highest efficiency
• Waterproof inverter with exactly and timely automatic island effect protection, adopt complementary PWM to push-pull pure sine wave, constant current, constant power---constant current and output power without any overload, over-current phenomenon
• Grid-tie micro-inverter,stack using inverter---- Such as: 4 micro inverter of 260W stacking can achieve 1040W. The number of the stacking is unlimited

400W smart micro inverter, grid tie solar power inverter is adopted 433MHz wireless communication mode for communication, IP65 waterproof protection, electricity transmission rate of up to 99%. 24V/ 48V (22-60V DC) to 120V (80-160V AC)/ 230V (180-280V AC) 50Hz/ 60Hz, built-in high-performance MPPT function, peak output power up to 400 watt.
