Item No.: SRM004
SRM33 Series is an intelligent multi-function solar inverter, consist of an MPPT solar Controller (high-power MPPT Controller external installation), charger, rectifier, inverter, static switch, main control circuit, and display alarm circuit, and so on.
Description Specification
PV–Grid–Battery: This series PV inverter design for photovoltaic(PV) and Grid sharing function, solar priority, photovoltaic through the MPPT controller supply to the inverter, and outputs a pure sine AC to loads, meanwhile charging the battery pack; When the solar is not enough to supply the load, it is supplemented by the grid power; utmost use solar energy and grid power, to reduce battery discharge, external battery life span.

  • LCD touch screen for visualization of operation
  • Pure sine wave output for different types of loads
  • External MPPT solar charge controller
  • A wide range, high accuracy and full automatic voltage stabilization
  • Intelligent optimization SOC control and independent three-stage PV charge management for battery to improve charge efficiency
  • Overall protection functions (battery overcharge protection, battery under voltage protection, overload protection, short circuit protection and over temperature protection)
  • Main supply priority mode, saving mode and battery priority mode are all settable, thus making it easy to meet the different application need of users
