Audited Supplier The STS series, developed 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 exceptional response speed, reliability, and industrial standard.
Featuring four charge modes - only solar power, mains power priority, solar power priority, and mains power & solar power - this inverter provides flexibility to meet various application needs. The selectable inverter and mains outputs further enhance its versatility.
The solar charge module incorporates the latest optimized MPPT tracking technology, enabling it to quickly track the maximum power point of the PV array in any environment. This real-time tracking ensures maximum energy generation from the solar panel, thanks to its wide voltage range of MPPT.
The AC-DC charge module utilizes an advanced control algorithm to achieve full digital double closed-loop control of voltage and current. With high control accuracy and a compact design, it provides stable and reliable charging and protection for the battery. The wide AC voltage input range and full input/output protection function further enhance its performance.
The DC-AC inverter module, based on a full digital intelligent design, employs advanced SPWM technology to convert DC into pure sine wave AC. It is suitable for powering various AC loads, including household appliances, electric tools, industrial devices, and electronic audiovisual equipment. The segment LCD display design allows real-time monitoring of system operation data and status. Additionally, the comprehensive electronic protection function ensures the safety and stability of the entire system.

Company: Guangdong Solarthon Technology Co., Ltd.
Are your inverters pure sine wave output?
Yes, all our inverters are true pure sine wave output.
What kind of output can you provide?
We normally produce inverters with 110V, 115V, 120V, 220V, 230V, and 240V, 50/60Hz self-adaption. If you have special requirements, please consult our engineers.
What's the difference between low frequency and high frequency inverters?
Low frequency inverters have various protections, strong adaptability to the environment, and are more reliable with voltage regulation capabilities.
What's the difference between pure sine wave and modified sine wave inverters?
Pure sine wave output inverters are 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, providing protection for appliances. 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 do not work well with modified wave inverters.
What appliances can your inverters load?
Our inverters can be used with household, office, agricultural appliances, and other inductive loads such as refrigerators, air conditioners, and water pumps.
Can you print our company logo on inverters, nameplates, and packaging?
Yes, we accept OEM orders and can print your company logo on inverters, nameplates, and packaging.
How do I choose the right inverter?
Tell us your requirements, and our sales team will recommend a suitable inverter for you.
How do I solve technical problems?
We offer 24-hour after-service consultancy to help you solve any technical problems easily.
Do I need a power inverter?
While not absolutely required, a power inverter is necessary if you want to have 220 or 230 volts AC and use normal AC appliances. Without a power inverter, you can only rely on battery power, which may be acceptable for small RVs or cabins.
What's the difference between 12, 24, and 48 volt inverters?
The voltage refers to the input voltage from the battery bank. Higher voltages result in lower currents, allowing the use of smaller wires between the solar panel array and battery bank. It is important to ensure that the Solar Panels, Inverter, and Battery Bank all use the same voltage.
What should I do if the product is broken?
If any product is faulty, simply send us pictures or videos, and we will study the issue and provide free spare parts or PCB board for after-sale service.
