Product Overview

This inverter converts 48V DC to 220V AC. It is designed to be hardwired to the electrical panel board of a home or small office, via the 4-pole terminal block connector on the back. Four 12 volt rechargeable batteries need to be connected externally to the unit. ‘Deep-cycle’ lead-acid batteries are recommended.

As longs as input (grid) voltage remains within 180~260 Vac, the connected batteries will be charged automatically. If grid voltage falls below 180 volts or rises above 260 volts, the unit will switch automatically to inverter mode, and will use the energy stored in the batteries to provide clean sine wave power at a stable voltage to selected electrical circuits in the premises.

When grid power is restored to normal, these circuits will once again receive power directly from the grid and the unit will switch back to battery charging mode. No manual intervention is needed.

Key Features

  • 220 V pure sine wave output that is compatible with all types of electrical and electronic equipment, including those containing mains transformers and motors.
  • Rated at 3500 VA and 2940 W, which is enough to power most domestic appliances and office equipment.
  • Supports connecting four batteries (in series) for longer backup time.
  • Supports a wide range of battery types: Flat Plate, Tubular & VRLA (SMF).
  • Adaptive Battery Charging Control (ABCC) system with a maximum charging current of 21 amperes enables faster charging while protecting against over-charging.
  • Simple to operate, with an intuitive display to easily check grid power availability, battery status, etc.
  • Short-term over-load handling capability to accommodate momentary high current requirements of some appliances.
  • Two fast-acting MCBs on the back panel provide protection against short-circuits and reverse polarity battery connection.
  • Bypass switch for supplying output directly from the grid in case of a fault in the inverter.
