Build a more independent power solution with this robust off-grid solar inverter, designed to convert 48V DC battery power into usable single-phase AC electricity. It is a practical choice for homes, farms, workshops and businesses that need reliable solar energy system support. The large front LCD screen makes key operating information easy to view at a glance, while the upright cabinet design keeps powerful inverter equipment neatly contained. Mounted on castor wheels, it is also easier to position in an appropriate installation area than a fixed, heavy cabinet.
Key Features & Benefits
- Off-grid solar power capability: Converts 48V DC input into AC power for standalone solar energy systems.
- Flexible AC output compatibility: Supports 110V, 120V, 220V and 240V output voltage options, with 50/60Hz output frequency.
- Clear LCD monitoring: The built-in front display and button controls provide a convenient, central view of inverter operating status.
- Pure sine wave inverter marking: The front panel is clearly marked “Pure Sine Wave Inverter” for a professional solar power setup.
- Smart fan cooling: Dual rear cooling fans and multiple ventilation grilles assist with heat management during operation.

- Convenient communications options: RS485 is included, with optional WiFi and GPRS communications available for system monitoring requirements.
- Accessible rear connections: Clearly labelled battery, AC input and AC output connection areas help keep the installation layout organised.
- Integrated switch and breaker area: Rear-mounted controls offer practical access for system operation and isolation.
- Mobile floor-standing cabinet: Four castor wheels make this 82kg inverter easier to move into position before final installation.
Design & Build
This solar inverter has a substantial floor-standing cabinet format measuring 650 x 410 x 890mm. Its black enclosure delivers a clean, professional look suited to dedicated power rooms, garages and utility areas. The front panel features a recessed LCD control section with contrasting yellow accents, status indicators and tactile buttons, while the lower perforated grille supports airflow. Side ventilation slots, dual rear fan guards and neatly arranged rear connection panels reinforce its purpose-built, equipment-grade appearance. The four-wheel base is a particularly useful visible detail for handling and placement.
Ideal For
This DC/AC inverter is well suited to off-grid solar power systems for homes seeking backup or independent electricity, as well as smallholdings, farm buildings, workshops, security installations and remote sites. With a 20A output current and single-output configuration, it can form a key part of a properly planned battery and solar solution. Select the appropriate inverter capacity option for your intended loads and have the unit installed and configured by a qualified solar professional.
