ON/OFF GRID SOLAR INVERTER 7.2KW/8.2KW/10.2KW
Introducing the STS series, a cutting-edge solar storage inverter designed by Guangdong Solarthon Technology Co., Ltd. This innovative inverter seamlessly 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 unparalleled performance. It boasts a high response speed, exceptional reliability, and meets the highest industrial standards.
The STS series offers four charge modes to cater to different application needs. You can choose between only solar power, mains power priority, solar power priority, or mains power & solar power. Additionally, the inverter and mains outputs are selectable, providing flexibility for various setups.
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 generates maximum energy in real-time, even in challenging conditions.
The AC-DC charge module incorporates an advanced control algorithm, enabling full digital double closed-loop control of voltage and current. This results in precise control accuracy and a compact design. The wide AC voltage input range and comprehensive input/output protection function ensure 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 AC power. This makes it suitable for a wide range of AC loads, including household appliances, electric tools, industrial devices, and electronic audiovisual equipment. The segment LCD display provides real-time operation data and system status, while the comprehensive electronic protection function guarantees the safety and stability of the entire system.

Product Description:
Q: Are your inverters pure sine wave output?
A: Yes, all our inverters are true pure sine wave.
Q: What kind of output can you provide?
A: 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.
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 and modified sine wave inverters?
A: Pure sine wave output inverters are comparable to the public power grid and even better. They have a low repair rate, long lifespan, no harmonic pollution, and are environmentally friendly, providing protection for your appliances. On the other hand, modified sine wave output can have a negative impact on appliances and cannot load inductive loads such as air conditioners and refrigerators. Certain motor control circuits may not be compatible with modified sine waves.
Q: What appliances can your inverters load?
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.
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 can I solve technical problems?
A: We offer 24-hour after-service consultancy to help you easily solve any technical problems you may encounter.
Q: Do I need a power inverter?
A: Technically, no. A power inverter is not absolutely required for a solar energy system. However, without a power inverter, you will not have 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 allow for less current, enabling the use of smaller wires between the solar panel array and the battery bank. It's important to note that 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, you can send us pictures or videos for our review. We will provide the necessary spare parts of the PCB board free of charge for after-sale service.
