SDA-D4000AL Modified Sine Wave Power Inverter
Product Description
SDA-D4000AL is a high-capacity DC to AC power inverter independently developed and produced by Sunchonglic, our factory located in Foshan, Guangdong, China. This 24V inverter adopts advanced modified sine wave technology, which can convert the direct current stored in solar batteries into standard 220V alternating current that can be used by daily household appliances. It supports free switching between 50Hz and 60Hz output frequency, which can adapt to the power grid standards of Africa, The Middle East, Southeast Asia and most emerging markets. With 1700W continuous output and 4000VA instantaneous peak power, it can normally drive refrigerators, water pumps, lighting equipment, small household appliances and other electrical products, which is the ideal choice for off-grid solar power systems and household emergency backup power.
Features:
1. Multiple comprehensive safety protection functions
The inverter has built-in intelligent protection chips, including battery anti-reverse connection protection, low voltage alarm and automatic shutdown protection, over voltage protection, short circuit protection, overload protection and over temperature automatic power reduction protection. When the working state is abnormal, the machine will automatically cut off the output in time, which can effectively avoid damage to the inverter itself and the connected electrical equipment, and greatly extend the service life of the product. Built-in internal circuit fuse, easy to replace after overcurrent failure, low maintenance cost.
2. Humanized multi-port power supply design
This model is configured with two universal AC sockets, which can supply power to two high-power electrical appliances at the same time. At the same time, it is equipped with standard USB port and Type-C interface, which can charge mobile phones, tablets, power banks and other digital devices directly without additional chargers, meeting various power needs of users.
3. Clear LED digital display screen
Equipped with a high-brightness LED digital display, it can dynamically display the input battery voltage, AC output voltage in real time. Users can intuitively understand the remaining power of the battery and the working state of the inverter at any time, which is convenient for operation and maintenance.
4. Excellent heat dissipation performance and low energy consumption
Adopts large-area aluminum alloy heat dissipation shell and built-in silent cooling fan, which automatically adjusts the fan speed according to the working temperature, reduces noise while ensuring good heat dissipation. No-load current is less than 0.5A, the whole machine conversion efficiency exceeds 85%, which can reduce battery power loss and improve the utilization rate of solar energy.
