Product Description Product Description:Product
Description:1. Energy flows bi-directionally, i.e. it can
discharge from the battery side to the DC grid or charge from the
DC grid side to the battery.2. Fully automatic protection functions
for overheating, overload, short circuit, overcurrent,
etc.3.Selection of original imported power devices4.Fully digital
circuit design5.All the chips are industrial grade and can operate
normally in cold, high temperature and humid environment.6.The main
circuit adopts DSP chip produced by TI of America, Infineon IGBT
module and Infineon movement for driving and protection, which is
safe and reliable;7.The output is automatically synchronized with
the grid, the current harmonic content is low, and there is no
pollution and impact on the grid;8. Closed loop control of grid
connected current, controllable and adjustable.9.Wide input voltage
range, suitable for different occasions10.The system has all-round
power protection scheme and perfect self-test and protection
function. In case of system failure, it will stop working;11.The
circuit structure is compact and the maximum efficiency ≥ 96%;12.
Protection level can be customized according to the user's
needs;;13.Provide Ethernet interface, standard Modbus TCP
communication protocol. Detailed PhotosProduct
