Product Overview

The Victron Energy Phoenix Inverter 48/250 230V VE.Direct AU/NZ (PIN481251300) is the entry-level model in the 48V Phoenix Inverter VE.Direct AU/NZ range, delivering 250VA of continuous pure sine wave 230V AC output from a 48V DC battery bank. Fitted with an Australian and New Zealand standard plug for direct mains-compatible connection, it is designed for powering low-draw 230V domestic appliances from leisure and automotive 48V battery systems where a compact, reliable inverter is needed without the cost or size of a higher-rated unit.

Built on the proven full bridge plus toroidal transformer topology, the Phoenix 48/250 is short circuit proof and protected against overheating from overload or high ambient temperature. There is no built-in Bluetooth monitoring and configuration require the VE.Direct to USB interface cable (computer connection) or the optional VE.Direct Bluetooth Smart dongle for wireless access both sold separately. No automatic transfer switch is included; pair with the Victron Filax ATS for seamless AC source switchover in under 20 milliseconds.

Features & Benefits

• Pure sine wave output — all appliances, no compatibility issues — Pure sine wave 230V AC is compatible with every household and sensitive electronic device — laptops, LED lamp drivers, televisions, phone chargers, and medical equipment. Unlike modified sine wave inverters, pure sine wave output produces no buzzing in audio equipment, no overheating in motors, and no incompatibility with active power factor correction loads.
• 250VA at 48V — the entry point for 48V systems — At 250VA, this is the smallest output model in the 48V Phoenix VE.Direct AU/NZ range — suited to a single low-draw load such as a laptop, phone charger, LED lamp, or small electronic device. Always confirm your appliance's wattage is within the 250VA continuous output limit before connecting. For higher-draw loads, consider the 48/375 (PIN481371300) or 48/800 (PIN481801300).
• Full bridge + toroidal transformer — proven reliability — The toroidal transformer delivers high surge capability for inrush-demanding loads and inherently stable sine wave output. Short circuit proof and overheating protected — designed for long-term field operation across marine, caravan, vehicle, and off-grid environments.
• ECO Mode — standby power reduction — When load drops below the preset minimum (15W), the inverter shuts down and checks every 2.5 seconds for demand. If load exceeds the threshold, full operation resumes immediately. Reduces no-load standby consumption — directly relevant in 48V off-grid and battery-backed systems where standby draw affects battery autonomy.
• Dynamic cut-off — load-dependent battery protection — Adjusts the low battery voltage disconnect threshold based on current load. Under heavy load, a higher threshold prevents over-discharge from load-induced voltage sag; under light load, a lower threshold is acceptable. Protects the 48V battery bank accurately across all load conditions.
• VE.Direct port — configurable via cable or optional dongle — Access all inverter parameters via the VE.Direct port using either a VE.Direct to USB interface cable (computer) or the VE.Direct Bluetooth Smart dongle (wireless iOS, Android, and MacBook access). Both accessories are sold separately. Parameters include:
  • Low battery voltage alarm and cut-off levels
  • Dynamic cut-off threshold
  • Output voltage (210–245V)
  • Output frequency (50Hz or 60Hz)
  • ECO mode on/off and sense level
• Remote on/off — external control — An optional remote switch connects to the remote on/off input for external inverter control from a panel, switch, or relay.
• AU/NZ standard plug — direct mains connection — The AU/NZ plug connects directly to any standard 10A GPO — no adapter required for Australian or New Zealand use.
• No built-in transfer switch — For installations requiring transfer to a generator or shore power source, the Victron Filax ATS (less than 20ms switchover) is recommended. For AC input battery charging, a Victron MultiPlus is the more comprehensive solution.

Frequently Asked Questions

What loads can a 250VA inverter realistically power?

At 250VA, this inverter suits a single low-draw load — a laptop (45–90W), phone charger, LED lamp, or small electronic device. Common household appliances including kettles, microwaves, and power tools far exceed 250VA. Always verify your appliance's wattage before connecting.

Does this inverter have built-in Bluetooth?

No. Wireless access requires the optional VE.Direct Bluetooth Smart dongle (sold separately). Computer-based access uses the VE.Direct to USB interface cable (also sold separately). Neither is included.

How does this compare to the 48/375 and 48/800 models in the range?

All three use the same Phoenix VE.Direct platform with identical features. The difference is output: 250VA (this model), 375VA (PIN481371300), and 800VA (PIN481801300). The Smart 48/2000 adds built-in Bluetooth at 2000VA. Choose based on your maximum continuous load requirement.

Does this inverter include a transfer switch?

No. The Victron Filax ATS (less than 20ms switchover) is recommended for installations requiring AC source transfer. If AC input battery charging is also needed, a Victron MultiPlus is the more complete solution.

What is dynamic cut-off and how does it protect my batteries?

Dynamic cut-off adjusts the low battery disconnect voltage based on current load — a higher threshold under heavy load prevents over-discharge from voltage sag, while a lower threshold is acceptable under light load. This protects battery health more accurately than a fixed voltage threshold.
