Independent power supply inverter / grid-connected inverter

Independent power supply inverter / grid-connected inverter

All microgrid converters can be configured with this device model!

We offer "independent power inverters/grid-connected inverters" that can operate in charging mode from systems such as batteries. They can supply AC loads from batteries and DC power sources. Additionally, during power outages or when disconnected from the grid, they can operate independently as sine wave inverters. This single model can configure all converters for microgrids, and we can also accommodate custom requests for JET certification compliance. 【Modes】 ■ Independent operation mode without grid connection ■ Charging mode to batteries when connected to the grid ■ Discharging mode from batteries when connected to the grid *For more details, please download the PDF or contact us.

Explanatory Material "The Trap of Output Derating" <Currently Available for Free>

Explanatory Material "The Trap of Output Derating" <Currently Available for Free>

Explain the impact of power supply installation direction on output derating. This serves as a reference to avoid design rework and shorten the lifespan of the power supply.

Output derating" is one of the rules for power supply usage and is a concept related to operating conditions and output power. If design progresses without considering output derating, various issues may arise, such as shortened lifespan, induced failures, and adverse effects on the entire system. This document focuses on output derating in equipment design and explains the impact of power supply installation direction and ambient temperature on the design. If you are concerned about power supply lifespan and safety, please take a moment to read this! [Contents] ■ Characteristics of output derating ■ Power supply installation direction and output derating ■ Operating ambient temperature and output derating ■ Ambient temperature measurement points * The explanatory document "The Trap of Output Derating" can be viewed immediately via "PDF Download.
