TFCFL WVC-700W Solar Grid-Tie Microinverter — IP65 Waterproof, Aluminum Alloy

Overview: The TFCFL WVC-700W is a compact, waterproof grid-tie microinverter built from durable aluminum alloy for long service life and corrosion resistance. Its small footprint (8.39*2.28*9.84inch) and lightweight construction make it easy to install without taking up much space. Power and Efficiency: Equipped with high-precision maximum power point tracking (MPPT) and efficient power reverse transmission technology, this inverter captures and locks the panel’s peak output and can boost generation by more than 25%. Excess energy can be sent back to the grid with a power transmission rate up to 99.9%. Control and Display: A front LCD screen provides real-time monitoring of voltage, power, frequency, current, etc. The unit uses intelligent soft switching, high-frequency switching power supply technology, and 32-bit DSP full digital SPWM control technology for fast, stable, and interference-resistant operation. Safety and Isolation: Input and output are fully electrically isolated with a fully isolated booster circuit for improved insulation and reliability. Built-in protections include over-temperature protection, under-voltage alarm, under-voltage protection, over-voltage protection, short circuit protection, and overload protection. The enclosure is IP65 rated to guard against rain and surface erosion. Installation Flexibility: Multiple units can be stacked or paralleled to form a single-phase parallel stacking system, or combined to create a three-phase AC system. The inverter’s design uses high-frequency telephone, micro processing, and related technologies to keep the device compact and efficient. Maintenance and Service: After installation you generally do not need routine maintenance—periodic cleaning of dust from photovoltaic panels is sufficient. If you encounter quality issues, please contact the seller for support. Important Installation Notes and Electrical Requirements: - The AC output port must be connected to the home grid to operate as a grid-connected inverter. Do not attempt to use the AC output without grid connection. - When using solar panels as the input source, the VOC must be between 30-48V. We recommend sizing solar panels at about 20% higher than the inverter rating. For example, if the product is 600W, the total solar panel power should be between 700-750W. - When the input source is a battery, the recommended battery voltage is 36V (can be achieved by connecting three 12V batteries in series). Do not reverse polarity when connecting. - Recommended battery currents: 36V/10mah for 300W, 36V/20mah for 600W, and 36V/40-45mah for 1200W. - Ensure input and output voltages are within the inverter’s normal operating range for proper grid-connected operation. Safety Precautions: Install the inverter according to the manual. Do not disassemble—repairs should only be performed by qualified maintenance personnel. Install in a well-ventilated, low-humidity location and keep combustible or explosive materials away. Keep children away from the unit to avoid electric shock. Notes on Purchase: Please allow slight color differences due to photography and a 1-3cm measurement variance from manual measurement. Make sure you accept these conditions before ordering.
