Premium Material: The inverter is made of aluminum alloy, which is durable, and not easy to rust. You can use it for a long time without frequent replacement, and your cost can be saved. High Efficiency: The inverter has built-in high-precision maximum power point tracking, which can optimize the power collection from the solar panel, accurately capture and lock the maximum output power point, and greatly increase power generation to more than 25%. In addition, the efficient power reverse transmission technology can transmit the power that can not be used up to the grid in the reverse direction to other places for use, and the power transmission rate can reach 99.9%. LCD Display: The inverter is equipped with an LCD display screen to monitor voltage, power, frequency, current, etc. So you can see the machine clearly in operation. Digital Control: The inverter adopts intelligent soft switching technology, high-frequency switching power supply technology, and 32-bit DSP full digital SPWM control technology, making the product strong anti-interference ability, fast operation speed, high intelligence, and a powerful functional system, which can meet the needs of users. Safety Guard: The inverter has six protection functions: over-temperature protection, under-voltage alarm, under-voltage protection, over-voltage protection, short circuit protection, overload protection, etc. Besides, the IP65 waterproof design can prevent rain from eroding its surface, so you can use it with confidence.
