Safety Precautions

General Safety: Always read and follow all safety instructions and cautions before operating the inverter. Improper operation can lead to personal injury or property damage.

DC Side: Ensure DC cables are connected tightly and securely. Use only the provided DC connectors. Mixing PV modules of different brands or models within the same MPPT may reduce system performance.

AC Side: Verify that the voltage and frequency at the connection point meet the inverter's grid connection requirements. Protective devices like circuit breakers or fuses are recommended, rated at least 1.25 times the maximum output current. Ensure all groundings are securely connected.

Inverter Warnings: Do not apply mechanical load to the terminals. Ensure all warning labels are visible and intact after installation. Pay attention to high voltage, delayed discharge, and high-temperature hazards.

Personal Requirements: Only trained and qualified personnel should install, operate, maintain, and replace the equipment or its parts. Proper personal protective equipment (PPE) must be used.

Product Introduction

The SDT inverter is a three-phase PV string grid-tied inverter designed to convert DC power generated by PV modules into AC power, feeding it into the utility grid. The document includes circuit diagrams illustrating the internal structure and connections for various models.
