The STS series is a new solar storage inverter developed by Guangdong Solarthon Technology Co., Ltd. It is designed to integrate solar energy storage, mains charging energy storage, and AC sine wave output. With its advanced DSP control and control algorithm, the STS series offers high response speed, reliability, and industrial standard.
The STS series offers four charge modes, including only solar power, mains power priority, solar power priority, and mains power & solar power. It also allows the selection of inverter and mains outputs to meet various application needs.
The solar charge module in the STS series utilizes the latest optimized MPPT tracking technology, enabling it to quickly track the maximum power point of the PV array in any environment. This ensures the maximum energy output from the solar panel in real-time, with a wide voltage range of MPPT.
The AC-DC charge module in the STS series employs an advanced control algorithm to achieve full digital double closed-loop control of voltage and current. This results in high control accuracy and a compact design. The battery can be charged and protected reliably with a wide AC voltage input range and full input/output protection function.
The DC-AC inverter module in the STS series is based on a full digital intelligent design and utilizes advanced SPWM technology to output a pure sine wave. This allows it to convert DC into AC, making it suitable for powering AC loads such as 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. Furthermore, it is equipped with comprehensive electronic protection functions to ensure the safety and stability of the entire system.

Company name: Guangdong Solarthon Technology Co., Ltd.
Product Description:
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 your inverters produce?
A: Our inverters are typically produced with self-adaptive 110V, 115V, 120V, 220V, 230V, and 240V outputs at 50/60Hz. If you have any special requirements, please let us know for engineer consultation.
Q: What's the difference between a low frequency and high frequency inverter?
A: A low frequency inverter offers various protections, strong adaptability to different environments, and more reliability. It also has voltage regulation capabilities. On the other hand, a high frequency inverter lacks these features.
Q: What's the difference between a pure sine wave inverter and a modified sine wave inverter?
A: A pure sine wave output inverter is equivalent to the power grid, if not better. It has a low repair rate, long lifespan, no harmonic pollution, and is environmentally-friendly. It also provides protection for appliances. In contrast, a modified sine wave output inverter negatively impacts appliances and cannot handle inductive loads such as air conditioners and refrigerators. Certain motor control circuits are also incompatible with modified sine waves.
Q: What appliances can your inverters handle?
A: Our inverters can be used with 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 customize the products with your company logo.
Q: How do I choose the right inverter?
A: Simply inform us of your requirements, and our sales team will recommend a suitable inverter for you.
Q: How do I solve technical problems?
A: We offer 24-hour after-service consultancy to provide you with easy solutions to your technical problems.
Q: Do I need a power inverter?
A: Technically, no. A power inverter is not an absolute requirement for a solar energy system. However, without one, you won't 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.
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 currents, allowing for the use of smaller wires between the solar panel array and the battery bank. It's important to note that when deciding on a system voltage, the solar panels, inverter, and battery bank must 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 our assessment. We will provide free spare parts for the PCB board as part of our after-sale service.
