ON/OFF GRID SOLAR INVERTER 7.2KW/8.2KW/10.2KW
The STS series by Guangdong Solarthon Technology Co., Ltd. is a cutting-edge solar storage inverter that combines solar energy storage, mains charging energy storage, and AC sine wave output. With its DSP control and advanced control algorithm, this inverter offers high response speed, reliability, and industrial standard.
Featuring four charge modes - only solar power, mains power priority, solar power priority, and mains power & solar power - the STS series allows for flexible selection of inverter and mains outputs to meet various application needs.
The solar charge module utilizes the latest optimized MPPT tracking technology, enabling it to quickly track the maximum power point of the PV array in any environment and obtain real-time maximum energy from the solar panel. It has a wide voltage range of MPPT for enhanced performance.
The AC-DC charge module employs an advanced control algorithm for full digital double closed-loop control of voltage and current. With high control accuracy and a compact design, it ensures stable and reliable charging and protection of the battery. The module also offers a wide AC voltage input range and full input/output protection function.
The DC-AC inverter module, based on full digital intelligent design, utilizes advanced SPWM technology to output pure sine wave and convert DC into AC. It is suitable for powering AC loads such as household appliances, electric tools, industrial devices, and electronic audiovisual equipment. The product features a segment LCD display for real-time operation data and system status. With comprehensive electronic protection functions, it guarantees the safety and stability of the entire system.

Welcome to Guangdong Solarthon Technology Co., Ltd.! We are pleased to introduce our high-quality inverters that are designed to meet your power needs. Read on to learn more about our products:
Yes, all our inverters provide true pure sine wave output.
Normally, we produce inverters with 110V, 115V, 120V, 220V, 230V, and 240V, with a self-adapting frequency of 50/60Hz. If you have special requirements, please consult our engineers.
Low frequency inverters offer various protections, strong adaptability to different environments, and reliable voltage regulation. On the other hand, high frequency inverters lack these features.
Pure sine wave output inverters provide power that is as good as the public power grid, if not better. They have a low repair rate, long lifespan, no harmonic pollution, and are environmentally friendly. On the other hand, modified sine wave output inverters can negatively impact appliances and cannot load inductive loads such as air conditioners and refrigerators. Certain motor control circuits are also not compatible with modified sine wave inverters.
Our inverters can be used with household, office, agricultural appliances, and other inductive loads such as refrigerators and air conditioners.
Yes, we accept OEM orders and can customize the products with your company logo.
Simply tell us your requirements, and our sales team will recommend a suitable inverter for you.
We offer 24-hour after-service consultancy to help you easily solve any technical problems you may encounter.
While a power inverter is not absolutely required for a solar energy system, it is necessary if you want to use normal AC appliances. Without an inverter, you will only have battery power and not 220 or 230 volts AC.
The voltage refers to the input voltage from the battery bank. Higher voltages allow for less current, which means you can use smaller wires between your solar panel array and battery bank. It is important to ensure that the solar panels, inverter, and battery bank all use the same voltage.
If any product is faulty, please send us a picture or video, and we will study it and provide the necessary spare parts of the PCB board for free as part of our after-sale service.
