MTWB Series


Solar Inverter


MTWB Series

MTWB series bi-directional energy-storage inverter is applicable to both on-grid and off-grid PV systems. It can control the flow of energy intelligently. During the daytime, the PV plant generates electricity which can be provided to the loads, fed into the grid or charge the battery. The electricity stored can be released when the loads require it during the night.             Additionally, the power grid can also charge the storage devices via the inverter.

l   Charge controller and inverter integrated                                         

l   Intelligent battery management function

l   Capable of being grid-interactive or grid-independent

l   More security & performance for same costs

l   Monitoring inverters freely via computers

l   Fanless super silence design and enhancing product life

l   High frequency transformerless system

l   Wide voltage range

l   High efficiency up to 97%

l   LCD display panel

l   Wall mountable

l   IP-65 protection level
