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 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 allows you to select the most suitable mode to meet your specific application needs. Additionally, you have the flexibility to choose between inverter and mains outputs.
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 that you can obtain the maximum energy from your solar panels in real-time, thanks to its wide voltage range of MPPT.
The AC-DC charge module incorporates an advanced control algorithm, enabling 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, based on full digital intelligent design, utilizes advanced SPWM technology to output a pure sine wave. This allows you to power AC loads such as household appliances, electric tools, industrial devices, and electronic audiovisual equipment. The segment LCD display design provides real-time operation data and system status, while the comprehensive electronic protection function ensures the safety and stability of the entire system.

Are you in need of a reliable and efficient power inverter? Look no further than our pure sine wave inverters! Manufactured by Guangdong Solarthon Technology Co., Ltd., these inverters are designed to meet the reading habits of English-speaking natives.
Yes, all our inverters provide true pure sine wave output.
Our inverters are available in various output voltages, including 110V, 115V, 120V, 220V, 230V, and 240V. They also feature 50/60Hz self-adaption. If you have specific requirements, our engineers are available for consultation.
Low frequency inverters offer enhanced protection, adaptability to different environments, and reliable voltage regulation. On the other hand, high frequency inverters may lack these features.
Pure sine wave inverters provide output comparable to the public power grid, with low repair rates, long lifespan, no harmonic pollution, and environmental friendliness. On the other hand, modified sine wave inverters may negatively impact appliances, especially inductive loads like air conditioners and refrigerators.
Our inverters are suitable for household, office, and agricultural appliances. They can handle inductive loads such as refrigerators, air conditioners, water pumps, and more.
Yes, we accept OEM orders and can print your company logo on the inverters, nameplates, and packaging.
Simply share your requirements with our sales team, and they will recommend a suitable inverter for your needs.
We offer 24-hour after-service consultancy to assist you in solving any technical issues easily.
While a power inverter is not absolutely required for a solar energy system, it is essential if you want to use normal AC appliances. Without an inverter, you will only have battery power and won't have access to 220 or 230 volts AC.
The voltage refers to the input voltage from the battery bank. Higher voltages allow for lower currents, enabling the use of smaller wires between the solar panel array and the battery bank. It's important to ensure that the solar panels, inverter, and battery bank all use the same voltage.
If any product is faulty, simply send us pictures or videos, and we will study the issue. We provide free spare parts of PCB boards for after-sale service.
