PRODUCT DESCRIPTION
Victron Energy Phoenix Inverter 12V 800VA 650W 120V Pure Sine Wave VE.Direct GFCI UL 458 – PIN121800510
The Victron Energy Phoenix Inverter 12/800 120V converts 12V DC battery power into clean, stable 120V AC pure sine wave power for RV, marine, camper, off-grid solar and mobile power applications. Delivering 800VA capacity, 650W continuous power at 25°C and up to 1500W peak power, this Phoenix inverter combines reliable AC output with VE.Direct communication, a NEMA GFCI duplex outlet and configurable energy-saving features.
Built around Victron Energy's proven full-bridge and toroidal transformer design, the Phoenix 12/800 provides strong startup capability and dependable operation for electronics, appliances, lighting, tools and other compatible 120V AC equipment.
800VA inverter with 650W continuous output
The Phoenix Inverter provides 800VA capacity with 650W continuous output at 25°C and 560W at 40°C. Peak output of up to 1500W provides additional startup power for compatible equipment with higher initial power requirements.
120V pure sine wave AC power
Pure sine wave output provides clean AC electricity suitable for sensitive electronics and common household equipment. The inverter allows compatible 120V devices to operate from a 12V leisure, automotive or off-grid battery system.
NEMA GFCI duplex outlet
This North American model features a convenient NEMA 5-15R GFCI duplex outlet, providing direct AC connections for compatible equipment. The GFCI configuration makes the inverter particularly well suited for RV, marine and mobile electrical installations.
VE.Direct communication and monitoring
The integrated VE.Direct communication port provides access to inverter monitoring and configuration using compatible Victron Energy accessories. Users can monitor input voltage, output voltage, load percentage and alarms.
The VE.Direct port can also provide connectivity with compatible computers or mobile devices when the appropriate VE.Direct interface or Bluetooth Smart accessory is used.
Fully configurable operation
The Phoenix Inverter provides extensive configuration options, including low-battery alarm and reset levels, low-voltage cut-off and restart settings, dynamic load-dependent cut-off, output voltage, frequency and ECO Mode settings.
ECO Mode for reduced battery consumption
When ECO Mode is enabled, the inverter can automatically enter standby when AC demand falls below a configured level. It periodically checks the connected load and returns to normal operation when sufficient demand is detected, helping reduce unnecessary battery consumption.
High startup power and built-in protection
With up to 1500W peak power, the Phoenix 12/800 can accommodate the startup requirements of compatible loads such as certain electric tools, lighting systems and electronic power converters.
Integrated protection helps safeguard the inverter against output short circuit, overload, excessive battery voltage, low battery voltage, excessive temperature and excessive DC ripple. Fan-assisted cooling supports reliable operation under demanding conditions.
