DC16-28V version is suitable for 12V solar panel (Vmp18-20V; Voc20-24V)
Vmp = working voltage; Voc = open circuit voltage.
The starting voltage of the inverter is 16V. Therefore, the DC11V input cannot be used.
32V is only an instantaneous voltage, used as a buffer protection, not as a working voltage input. Otherwise it will damage the inverter.
The solar panel voltage will decrease with the intensity of the sunlight. After the inverter is started at 16V, it will work even if the panel voltage drops. We designed a wider voltage input range to allow the inverter to output more power. After the voltage is lower than 15V, the working efficiency will start to decline.
Please be noted, This grid tie inverter cannot be used as off grid/stand alone solar system. The output need to be connected to the grid power. Can not supply power directly to the AC loads.
Please use a 10 square cable, the cable length is not recommended to exceed 4M. Tighten the DC terminal wiring. If the cable is too thin or the connection is loose, the inverter will be damaged.
Smart Microinverter Introduction:
Smart grid tie inverter is a compact unit, which directly converts direct current into alternating current for powering appliances and/or office equipments and connecting to utility grid. The AC output from Smart Microinverter is synchronized and in phase with the utility grid. It is a key device of power generation systems such as PV power generation system, wind turbine power generation system. Smart Microinverter specially optimized design to work with modularization of DC power supplies which includes the mainstream solar modules, 18V (36 cells) monocrystal and/or Polycrystalline solar panels, wind turbines and batteries. Smart Microinverters are stabilization, reliable and high conversion efficiency items. It is the best choice for PV power generation systems.
Advantages of Smart Microinverter:
1. Unique circuit design, choice of import industrial electronic components, higher efficiency, more stable performance.
2. Creative MPPT technology, efficiency more than 99%, faster and more sensitive reaction, more reliable.
3. Parallel type design for DC input and modularization design for inverter, 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.

Inverter Diagram：
A. Inverter work with solar panels.
16-28VDC range is for 36cells-Vmp:18-21V:Voc:20-24V solar panels.
30-55VDC range is for 60cells-Vmp:26-30V:Voc:34-38V or 72cells-Vmp:35-39V:Voc:42-46V. This range can suitable for two version solar panels.
B. Inverter work with battery.
If you want to use this grid tie inverter for battery, then please use 24VDC battery with 16-28VDC inverter. 36VDC battery with 30-55VDC inverter.
Because this inverter is designed for solar panels which with MPPT function. So we don't very suggest customers to use it for battery. It may short the inverter service life.If use a battery to power the inverter, please use a circuit breaker.
