Overview

What it is

The MEAN WELL ISI-501-224B is a DC-AC inverter from the ISI-501 series (500 W True Sine Wave DC-AC Inverter with MPPT Solar Charger), rated 24 V DC to 230 V AC, 500 W.

What it is used for

Runs 230 V AC equipment from a 24 V lead acid battery bank and charges that battery from solar panels through the built-in MPPT charger, for sites without mains power. MEAN WELL lists applications such as home appliances, power tools, portable equipment, vehicles and yachts.

Key features

  • True sine wave output (THD <3%).
  • Surge power up to 1000 W.
  • Built-in 500 W MPPT solar charger, 98% MPPT efficiency (typ.).
  • Protections: battery low alarm, battery low shutdown, over voltage, over temperature, output short, input polarity reverse, overload.
  • Built-in remote ON/OFF control and battery low relay contact.
  • LED indicator for operation status and battery capacity.

Key Specifications

  • DC Input Voltage: 24 V DC battery (21 to 30 V DC), 30 A typ..
  • AC Output Voltage: 230 V AC factory setting; 200, 220, 230 or 240 V AC selectable by setting button.
  • Rated Output Power: 500 W.
  • Solar Input: MPPT range 35 to 90 V; open circuit voltage range 45 to 90 V; 7 A typ.; 500 W typ..
  • Battery Charging Voltage: 28.8 V (constant voltage stage of the MPPT solar charger).
  • Output Waveform: True sine wave (THD <3%).

Buying considerations

Size the unit with headroom above the connected load and check the derating information in the datasheet for high ambient temperature or low input voltage. Other models in the same series are listed on this page.

Installation considerations

MEAN WELL treats this unit as a component of the final equipment, so approvals and EMC performance should be confirmed for the complete installation. Wiring and safety details are in the official datasheet linked below.
