Off-Grid or Stand-Alone PV System

The Off-Grid or Stand-Alone PV System incorporates large amounts of battery storage to provide power for a certain number of days (and nights) in a row when sun is not available. The array of solar panels must be large enough to power all energy needs at the site and recharge the batteries at the same time.  You may have seen mini versions of the stand-alone system on remote road signs and radio towers..

This is a multi-function inverter ,combining functions of inverter and mppt solar charger controller, solar charger and battery charger to offer uninterrupted power support with portable size. The comprehensive LCD display offers user-configurable and easy-accessible button operation such as battery charging current, AC/solar charger priority, and acceptable input voltage based on different applications.

  • Inbuilt MPPT solar charge controller 30A~60A

  • Battery priority function

  • 12V/24V/48V input optional

  • Max. AC charge current 40A.

  • Pure sine wave output

  • LCD status display

  • 50Hz/60Hz automatic
