Remark:

DC power sources refer to devices which output voltage are match microinverter input voltage setting range as 22-46VDC, included solar panels, batteries, wind generators which DC current operate through AC to DC controller. 
AC power grid refer to single phase utility grid. Such as 110V(90-140V)and 220V(190-260V)single phase electrical utility service.


Brief 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 Micro inverter is synchronized and in-phase with the utility grid.It is a key device of power generation systems such as PV power generation system.

Smart Micro inverter specially optimized design to work with modularization of DC power supplies which includes the mainstream solar modules,36V (72cells) Moncrystal and/or polycrystalline solar panels and batteries.Smart Micro inverters are stabliation,reliable and high conversion efficiency items.It is the best choice for PV power generation system.

Smart Micro inverter can be easily placed and attached to the rack underneath of PV module.No need sapces for independent installation and low voltage DC wre connects from the PV module to smart Micro inverter can eliminate the risk of high DC voltage.Distributed modularization design philosophy for smart micro inverter insures the productiveness of the whole system and will not affect by a single point of failure.Each Smart Micro inverter is individually connected to each PV module in the array.This unique configuation means that an individual Maximum Peak Power Point Tracker(MPPT) controls each PV modules in the array which may be affected by shading,soiling,orientation or mismatch,etc.

Smart Micro inverter insures top performance for maximizing energy production from the whole PV system and gets return on investment in less time.
