Product: Y&H Grid Tie Inverter 600W Stackable DC30-55V PV Input AC110V MPPT Pure Sine Wave Micro Inverter fit for 30V 36V Solar Panel/36V Battery
Brand: Y&H
Is DC22V-60V not the working voltage? Why should the advertisement display DC22-60?
 Y&H grid tie inverter is designed for solar panels. The working voltage of solar panels depends on the intensity of sunlight, which means that the panel voltage varies. There is also an increase in voltage at the moment the solar panel starts. 
 1.Unique circuit design,choice of import industrial electronic components, higher efficiency,more stable performance.
 2.Creative MPPT technology,efficiency more than 99%,faster reaction,more sensitive of reaction and more reliable of Maximum power point locking.
 3.Parallel modular design,small volume,distributed installation,easy for system configuration,flexible for combination,strong expansibility of system.
 4.Adopting high-frequency isolation transformer type,high efficiency,and high security.
 5.Perfect electrical protection function.
 6.Aluminum alloy housing,not rust,heat-resisting and cold-resistant as well as anti-corrosion.
 7.Getting electronic circuit design,appearance design and other core technology patents.
 8.Wide input voltage(22-60VDC),suit for different DC power supply.

 Smart Grid Tie Microinverter Technical Parameters:
 (Compatible with 60 cells solar panel which Vmp is26-30V as well as Voc is 34-38V.)
 (Compatible with 72 cells solar panel which Vmp is35-37V as well as Voc is 44-46V.)
Grid Tie Inverter - DC22V-60V is suitable for 36V solar panel (Vmp30-36V; Voc38-46V) Vmp = working voltage; Voc = open circuit voltage.
Grid Tie Solar Inverter - The starting voltage of the inverter is 30V. Therefore, the DC22V input cannot be used.
Micro inverter - 60V is just an instant voltage. As a buffer protection, it cannot be used as a working voltage input. Otherwise it will damage the inverter.
Solar Inverter grid-tie - High performance Maximum Power Point Tracking(MPPT),Pure sine wave output.If the DC connection is loose and causes a short circuit, then smoke may be emitted.The inverter adopts aluminum alloy casing, so there is no fire.
On Grid Inverter - Small Size with high efficiency,Easy installation,Stackable.
