GTB series products are characterized by high efficiency, intelligence, safety and reliability. Using MPPT engine and intelligent wifi module, it can realize efficient energy conversion and remote monitoring. At the same time, the inverter has multiple safety protection functions, and the installation is simple and convenient. Excellent performance, equipped with smart home system, remote monitoring and control can be realized through smart life APP.
【MPPT TECHNOLOGY】 - Precise maximum power point tracking. MPPT algorithm can optimize the power collection from solar panels. It accurately captures and collects sunlight, and locks in the maximum output power points, significantly increasing over 25% of the power generation. With the monitoring system, it can help you monitor the power generation efficiency of the power station and reduce workforce expenses.
【HIGH PERFORMANCE】 - Reverse power transmission. With efficient reverse power transmission technology, the power transmission rate up to 99.9%. Full digital control can be achieved by using intelligent soft switching technology and built-in MCU for charging modules; Introducing high-frequency switching power supply and SPWM control technology. It features strong anti-interference ability, fast calculation speed, a high degree of intelligence, high control precision, and excellent output waveform.
【PROTECTIVE & RELIABLE】 - IP65 waterproof design and aluminum alloy material can effectively prevent rainwater erosion on the surface. It provides electrical isolation, more reliable to use. It offers multiple protection functions, such as over-current protection, short circuit protection, low-voltage protection, over high voltage protection.
【EASY OPERATION】 - Lightweight and easy to install, many inverters can be stacked arbitrarily to form a single-phase parallel stacking system. Almost no maintenance work is required, clean the dust on the photovoltaic panel occasionally.
【SUSTAINABLE USE】 - This solar power grid-tie micro-inverter can convert DC power generated by solar panels into AC power. Our solar inverter provides sustainable energy and brings excellent environmental benefits.
By cooperating with smart home systems, GTB series micro inverters can realize intelligent online monitoring. Through the smart life APP and the Internet, users can monitor key information such as the working status and output power of the inverter in real time. Supports remote control, allowing users to keep track of system operation and improve energy efficiency.
