Audited Supplier The STS series is a new solar storage inverter developed by Guangdong Solarthon Technology Co., Ltd. This innovative inverter integrates 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.
Featuring four charge modes, including only solar power, mains power priority, solar power priority, and mains power & solar power, this inverter provides selectable inverter and mains outputs to cater to different application needs.
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 real-time maximum energy conversion from the solar panel, offering a wide voltage range of MPPT.
The AC-DC charge module implements an advanced control algorithm, enabling full digital double closed-loop control of voltage and current. With high control accuracy and compact design, this module provides stable and reliable battery charging and protection. It also supports a wide AC voltage input range and offers full input/output protection functions.
The DC-AC inverter module, based on full digital intelligent design, utilizes advanced SPWM technology to output a pure sine wave, effectively converting DC into AC. It is suitable for powering various AC loads, including household appliances, electric tools, industrial devices, and electronic audiovisual equipment.
With its segment LCD display, the STS series displays real-time operation data and system status. The comprehensive electronic protection function ensures the safety and stability of the entire system.

Are your inverters pure sine wave output?
Q: Yes, all our inverters provide true pure sine wave output.
What kind of output can your inverters provide?
Q: Normally, we produce inverters with 110V, 115V, 120V, 220V, 230V, and 240V, with 50/60Hz self-adaption. If you have special requirements, please consult our engineers.
What's the difference between low frequency and high frequency inverters?
Q: Low frequency inverters have various protections, strong adaptability to the environment, and are more reliable with voltage regulation.
What's the difference between pure sine wave inverter and modified sine wave inverter?
Q: Pure sine wave output inverters provide power equal to or better than the public power grid. They have a low repair rate, long lifespan, no harmonic pollution, and are environmentally-friendly. Modified sine wave output inverters have a negative impact on appliances and cannot load inductive loads like air conditioners and refrigerators. Certain motor control circuits are not compatible with modified wave inverters.
What appliances can your inverters load?
Q: Our inverters can be used with household, office, and agricultural appliances, as well as inductive loads such as refrigerators, air conditioners, water pumps, etc.
Can you print our company logo on inverters, nameplates, and packaging?
Q: Yes, we accept OEM orders and can customize inverters, nameplates, and packaging with your company logo.
How do I choose the right inverter?
Q: Simply tell us your requirements, and our sales team will recommend a suitable inverter for you.
How do I solve technical problems?
Q: We offer 24-hour after-service consultancy to help you solve any technical issues easily.
Do I need a power inverter?
Q: Actually, no. A power inverter is not absolutely required for a solar energy system. However, without one, you will not have 220 or 230 volts AC and will rely solely on battery power. While this may be acceptable for small RVs or cabins, most people prefer to use normal AC appliances.
What's the difference between 12, 24, and 48 volt inverters?
Q: The voltage refers to the input voltage from the battery bank. Higher voltages allow for lower current, enabling the use of smaller wires between the solar panel array and the battery bank. When choosing a system voltage, ensure that the solar panels, inverter, and battery bank all use the same voltage.
What should I do if the product is broken?
Q: If any product is faulty, please send us pictures or videos for review. We will provide the spare parts of the PCB board free of charge for after-sale service.
