Audited Supplier Introducing the STS series, a revolutionary solar storage inverter from Guangdong Solarthon Technology Co., Ltd. This cutting-edge inverter 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 unparalleled 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 STS series provides flexible options to meet various application needs. You can select between inverter and mains outputs depending on your requirements.
The solar charge module in the STS series utilizes the latest optimized MPPT tracking technology. This allows it to quickly track the maximum power point of the PV array in any environment, ensuring you obtain the maximum energy from your solar panel in real-time. The module also offers a wide voltage range of MPPT for added convenience.
The AC-DC charge module in the STS series employs an advanced control algorithm for full digital double closed-loop control of voltage and current. This results in high control accuracy and a compact design. With a wide AC voltage input range and full input/output protection function, the battery can be charged and protected stably and reliably.
The DC-AC inverter module in the STS series utilizes a full digital intelligent design and advanced SPWM technology. It outputs a pure sine wave, converting DC into AC seamlessly. 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 design allows you to monitor the operation data and system state in real-time. Additionally, the comprehensive electronic protection function ensures the safety and stability of the entire system.

A: Yes, all our inverters provide true pure sine wave output.
A: We normally produce inverters with 110V, 115V, 120V, 220V, 230V, and 240V, with 50/60Hz self-adaption. If you have special requirements, please consult our engineers.
A: Low frequency inverters have various protections, a strong ability to adapt to the environment, and are more reliable with voltage regulation.
A: Pure sine wave output inverters are just 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. Modified sine wave output inverters have a negative impact on appliances and cannot load inductive loads such as air conditioners and refrigerators. Certain motor control circuits don't work well with modified wave inverters.
A: Our inverters can be used with household, office, agricultural appliances, and other inductive loads such as refrigerators, air conditioners, water pumps, etc.
A: Yes, we accept OEM orders and can print your company logo on our products and packaging.
A: Simply tell us your requirements, and our sales team will recommend a suitable inverter for you.
A: We provide 24-hour after-service consultancy to help you easily solve any technical problems you may encounter.
A: Technically, no. A power inverter is not absolutely required for a solar energy system. However, without a power inverter, you will not have 220V or 230V AC power 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.
A: This refers to the input voltage from the battery bank. The main consideration is that higher voltages allow for lower currents, which means you can use smaller wires between your solar panel array and your battery bank. It's important to ensure that your solar panels, inverter, and battery bank all use the same voltage.
A: If any product is faulty, you can send us pictures or videos, and we will study the issue and provide free spare parts for the PCB board as part of our after-sale service.
