Audited Supplier ON/OFF GRID SOLAR INVERTER 7.2KW/8.2KW/10.2KW
The STS series 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 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, the inverter and mains outputs can be selected to cater to different application needs. The solar charge module utilizes optimized MPPT tracking technology, allowing it to quickly track the maximum power point of the PV array in any environment and maximize solar panel energy in real-time.
The AC-DC charge module employs an advanced control algorithm for full digital double closed-loop control of voltage and current, ensuring high control accuracy and compact size. With a wide AC voltage input range and comprehensive input/output protection function, the battery can be stably and reliably charged and protected.
The DC-AC inverter module, based on full digital intelligent design, utilizes advanced SPWM technology to output pure sine wave and convert DC into AC. This makes it suitable for powering various AC loads, including household appliances, electric tools, industrial devices, and electronic audiovisual equipment. The product also features a segment LCD display for real-time operation data and system state monitoring. With its comprehensive electronic protection function, the Solarthon inverter guarantees safety and stability for the entire system.

Q: Are your inverters pure sine wave output?
A: Yes, all our inverters have a true pure sine wave output.
Q: What kind of output can you provide?
A: We normally produce inverters with 110V, 115V, 120V, 220V, 230V, and 240V, 50/60Hz self-adaption. If you have special requirements, please consult with our engineers.
Q: What's the difference between low frequency and high frequency inverters?
A: Low frequency inverters offer various protections, adapt well to different environments, 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, with low repair rates, long lifespan, no harmonic pollution, and protection for appliances. Modified sine wave output can negatively impact appliances and cannot load inductive loads like air conditioners and refrigerators. Certain motor control circuits may not work well with modified wave inverters.
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 and can incorporate your company logo.
Q: How do I choose the right inverter?
A: Let us know 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 help you solve technical problems easily.
Q: Do I need a power inverter?
A: While not absolutely required, a power inverter is necessary if you want to use normal AC appliances. Without one, you will only have battery power and not have 220 or 230 volts AC. This may be acceptable in a small RV or cabin.
Q: What's the difference between 12, 24, and 48 volt inverters?
A: The voltage refers to the input voltage from the battery bank. Higher voltages allow for less current, enabling the use of smaller wires between your solar panel array and battery bank. It's 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, and we will study the issue. We will provide spare parts of the PCB board free of charge for after-sale service.
