Audited Supplier Introducing the STS series, a cutting-edge solar storage inverter from Guangdong Solarthon Technology Co., Ltd. This innovative inverter combines solar energy storage, mains charging energy storage, and AC sine wave output. With its DSP control and advanced control algorithm, the STS series offers high response speed, reliability, and industrial standard.
The STS series features four charge modes to suit different application needs: only solar power, mains power priority, solar power priority, and mains power & solar power. You can select between inverter and mains outputs, providing flexibility and versatility.
The solar charge module utilizes the latest optimized MPPT tracking technology, allowing it to quickly track the maximum power point of the PV array in any environment. This ensures that the solar panel can generate maximum energy in real time, thanks to its wide voltage range of MPPT.
The AC-DC charge module employs an advanced control algorithm for full digital double closed-loop control of voltage and current. This results in high control accuracy and a compact design. The module supports a wide AC voltage input range and offers full input/output protection, ensuring stable and reliable battery charging and protection.
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 a wide range of AC loads, including household appliances, electric tools, industrial devices, and electronic audiovisual equipment. The product features a segment LCD display that provides real-time operation data and system status. With comprehensive electronic protection functions, the STS series guarantees safety and stability for the entire system.

Company Name: Guangdong Solarthon Technology Co., Ltd.
A: Yes, all our inverters provide true pure sine wave output.
A: Normally, we produce inverters with 110V, 115V, 120V, 220V, 230V, and 240V, 50/60Hz self-adaption. If you have special requirements, please consult our engineers.
A: Low frequency inverters have various protections, strong adaptability to the environment, and are more reliable with voltage regulation.
A: Pure sine wave output inverters provide power that is just 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 have a negative impact on appliances and cannot load inductive loads such as air conditioners and refrigerators. Certain motor control circuits may also not be compatible with modified sine wave inverters.
A: Our inverters can be used with household, office, agricultural appliances, and other inductive loads such as refrigerators, air conditioners, water pumps, etc.
A: Yes, we accept OEM orders and can customize the products with your company logo.
A: Simply tell us your requirements, and our sales team will recommend a suitable inverter for you.
A: We provide 24-hour after-service consultancy to help you easily solve any technical problems you may encounter.
A: Technically, no. A power inverter is not absolutely required for a solar energy system. However, without a power inverter, you will not have access to 220 or 230 volts AC and will have to rely solely on battery power. While this may be acceptable for small RVs or cabins, most people prefer to use normal AC appliances.
A: The voltage refers to the input voltage from the battery bank. The main consideration is that higher voltages result in lower currents, allowing for the use of smaller wires between the solar panel array and the battery bank. It is important to ensure that the solar panels, inverter, and battery bank all use the same voltage.
A: If any product is faulty, you can send us pictures or videos, and we will study the issue and provide the necessary spare parts of the PCB board for free as part of our after-sale service.
