ON/OFF GRID SOLAR INVERTER 7.2KW/8.2KW/10.2KW
Introducing the STS series, a new solar storage inverter from Guangdong Solarthon Technology Co., Ltd. This innovative product combines 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.
The STS series offers four charge modes to meet different application needs:
Furthermore, the inverter and mains outputs are selectable, providing flexibility for various setups.
The solar charge module 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 real-time maximum energy generation from the solar panel, even with a wide voltage range of MPPT.
The AC-DC charge module features advanced control algorithms for full digital double closed-loop control of voltage and current. With high control accuracy and a compact design, it provides stable and reliable charging and protection for the battery. The wide AC voltage input range and full input/output protection function further enhance its capabilities.
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 a wide range of AC loads, including household appliances, electric tools, industrial devices, and electronic audiovisual equipment.
The STS series also features a segment LCD display that shows real-time operation data and system status. With comprehensive electronic protection functions, the product ensures the safety and stability of the entire system.

Company: Guangdong Solarthon Technology Co., Ltd.
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, with a self-adaption of 50/60Hz. If you have any special requirements, please consult our engineers.
Q: What's the difference between low frequency and high frequency inverters?
A: Low frequency inverters offer various protections, a strong ability to adapt to different environments, and reliable voltage regulation. They are more reliable compared to high frequency inverters.
Q: What's the difference between pure sine wave inverter and modified sine wave inverter?
A: Pure sine wave output inverters are as good as the public power grid, if not better. They have a low repair rate, long lifespan, no harmonic pollution, and are environmentally friendly. They also provide protection for appliances. On the other hand, modified sine wave output inverters have a negative impact on appliances, cannot load inductive loads (e.g., air conditioners, refrigerators), and may not be suitable for certain motor control circuits.
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 print your company logo on our 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 offer 24-hour after-service consultancy to help you solve any technical problems easily.
Q: Do I need a power inverter?
A: Technically, no. A power inverter is not absolutely required in a solar energy system. However, without a power inverter, you won't have 220 or 230 volts AC and will solely rely 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. Higher voltages allow for lower current, which means you can use smaller wires between your solar panel array and battery bank. Keep in mind that when choosing 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, you can send us pictures or videos for our analysis. We will provide the necessary spare parts of PCB board free of charge for after-sales service.
