Audited Supplier The STS series by Guangdong Solarthon Technology Co., Ltd. is a new 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 - this inverter allows you to select the desired output to meet different application needs.
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 and obtain the maximum energy from the solar panel in real-time. It also offers a wide voltage range of MPPT.
The AC-DC charge module utilizes 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. Additionally, it has a wide AC voltage input range and full input/output protection function.
The DC-AC inverter module, based on full digital intelligent design, employs 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 inverter features a segment LCD display that shows real-time operation data and system status. Furthermore, it offers comprehensive electronic protection functions for enhanced safety and stability.

Q: Are your inverters pure sine wave output?
A: Yes, all our inverters provide true pure sine wave output.
Q: What kind of output can you provide?
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.
Q: What's the difference between low frequency and high frequency inverters?
A: Low frequency inverters have various protections, strong adaptability to the environment, and are more reliable with voltage regulation.
Q: What's the difference between pure sine wave inverters and modified sine wave inverters?
A: Pure sine wave output inverters provide power similar to the public power grid, if not better. They have a low repair rate, long lifespan, no harmonic pollution, and are environmentally friendly, ensuring appliance protection. 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.
Q: What appliances can your inverters load?
A: Our inverters can be used for household, office, agricultural appliances, and other inductive loads such as refrigerators, air conditioners, water pumps, etc.
Q: Can you print our company logo on inverters, nameplates, and packaging?
A: Yes, we accept OEM orders and can print your company logo on the inverters, nameplates, and packaging.
Q: How do I choose the right inverter?
A: Simply tell us your requirements, and our sales team will recommend a suitable inverter for you.
Q: How do I solve technical problems?
A: We provide 24-hour after-service consultancy to assist you in solving any technical issues easily.
Q: Do I need a power inverter?
A: Actually, it is not absolutely required, but if you don't use one, you will not have 220 or 230 volts AC and will only rely on battery power. While this might be acceptable in a small RV or cabin, most people prefer to use normal AC appliances.
Q: What's the difference between 12, 24, and 48 volt inverters?
A: This refers to the input voltage from the battery bank. The main consideration is that higher voltages result in lower current, 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.
Q: What should I do if the product is broken?
A: If any product is faulty, please send us pictures or videos for further analysis. We will provide free spare parts for the PCB board as part of our after-sale service.
