Product Description

48VDC Small Office 8kw Solar Inverter Charger


8kw Solar Backup Inverter Charger for Small Office, Bank, Hotel


Kinergier Pro series


Kinergier Pro delivers high reliability, performance and
industry leading efficiency for mission critical application.
Its distinguishing surge capability makes it capable to power
most demanding appliances, such as air conditioner, water
pump, washing machine, freezer etc.


As the new models of Energier Essential family, Energier Essential II is especially developed for big residential and commercial project featuring industry leading efficiency and UPS grade transfer time. It integrates multiple functions, including a powerful battery charger, true sine wave inverter and a high-speed automatic transfer switch.

With the function of AEA (automatic energy allocation), it
can be used to work with a limited AC source such as
generator or limited grid. Kinergier Pro can automatically
adjust its charging current avoiding grid or generator to be
overloaded. In case of temporary peak power appears, it
can work as the supplement source to generator or grid.




  • UPS class speed, 2ms transfer
  • Support AC coupling DC coupling system and system,solar hybrid systems
  • Parallel and three phase capability, up to 9 units can operate in parallel
  • Can be used for self consumption system support feed back to grid
  • AEA function ( ower assist) p sharing and power
  • Outstanding overload capability for all kinds of inductive loads
  • Harmonic distortion <2%
  • High efficiency up to 96%
  • Extremely low status consumption power
  • TBB premium II battery charging management
  • With built in battery SOC estimation
  • Two programmable AC outputs for smart load management
  • Built in AGS
  • Fully programmable by APP
  • Remote monitoring and control available
