Pure Sine Wave Power Inverters for Home, RV, and Solar System

ADVANCED PURE SINE WAVE TECHNOLOGY The VOLFVERT PR-4000w inverter provides true 4000W continuous and 8000W peak power, utilizing 12V to 110/120VAC pure sine wave technology. This advanced design delivers higher energy efficiency (>90%) and lower no-load loss, enabling a more energy-saving modern lifestyle.

HEAVY DUTY SUPPORTING FEATURES This versatile inverter is equipped with a comprehensive set of connection options, including 4 AC outlets, 1 AC terminal block, 2 USB ports (5VDC, max 3.4A), and 1 Type-C port (max 18W). The LCD display allows for easy monitoring and control of the inverter's operation.

CONVENIENT WIRELESS REMOTE CONTROL The included wireless remote control enables you to operate the pure sine wave inverter conveniently, anytime and anywhere, within a range of 100 feet.

CLEAR LCD DISPLAY AND SAFETY PROTECTION The upgraded LCD display provides clear indication of the inverter's status and any warning signals, allowing you to identify and address any issues quickly. The inverter is equipped with advanced protection features, including over-heating, short circuit, under-voltage, over-voltage, overload, and reverse connection safeguards. Coupled with a user-friendly system (sound alert and automatic restart), the inverter will always operate in a secure state, ensuring the safe and smooth running of your devices.

DURABLE DESIGN AND LONG-LASTING PERFORMANCE The intelligent temperature control system, featuring a built-in ultra-silent thermoactivated cooling fan, keeps the inverter working properly and quietly. The aviation-grade aluminum housing prevents oxidation and deformation, while also providing excellent heat dissipation to prolong the inverter's lifespan.

COMPREHENSIVE WARRANTY AND CUSTOMER SUPPORT VOLFVERT offers a 24-month warranty on this product and provides 24/7 customer service. The package includes the 4000W pure sine wave inverter, a user manual, two battery cables (one red, one black), and a wireless remote controller.

FREQUENTLY ASKED QUESTIONS 1. Q: With a 2000-watt load, there is a strange noise or the inverter does not work and shuts down. A: The maximum output power of a single socket is 1850W. Due to potential voltage fluctuations, it is recommended to use appliances with a nominal power of 1700W or less. Appliances above 1850W should be connected to the AC terminal blocks; otherwise, the inverter may be damaged or shut down.

1. Q: The power consumption shown on the screen does not correspond to the nominal power of the appliance. A: The actual power consumption of an appliance can be higher than its nominal power due to various factors. This is because the nominal power may have a ±10% error margin, and the actual power is positively related to the input voltage. For example, an air conditioner with a nominal power of 2000W may consume up to 2400W at a maximum input voltage of 120V.

2. Q: The inverter gets hot during operation, but it still operates normally. A: The operation of the inverter generates high temperatures, which is why a high-quality aluminum housing is used to dissipate heat quickly. The inverter has an overheat protection feature, and it will automatically shut down and restart when it cools down. If the machine is running properly, it means the heat dissipation is working as intended, and it is safe to use.
