DEYE inverter adjustment: from 400V to 230V three-phase
In this video, we'll explain how to configure the DEYE inverter to transform a 380V three-phase output into a 230V three-phase output. With this configuration, both the LOAD output and the GRID input will automatically adjust to 230V three-phase, i.e., approximately 130V per phase. ⚠️ Very important! This procedure must be performed without connecting any load (LOAD) or grid (GRID) to the inverter. You can use batteries or solar panels (PV) to temporarily power the system and thus turn on the inverter and complete the configuration. Once the change is complete, use a multimeter to verify that the phases are correctly delivering approximately 127V before connecting the LOAD output and the GRID input. Let's see it step by step! The adjustment is very simple: Enter the configuration menu, look for the “Grid Setting” option and change the parameter from: LN:220V / LL:380V (AC) to LN:127V / LL:220V (AC) With this change, both the LOAD output and the GRID input will work at 230V three-phase. And if one day you need to return to the standard 400V three-phase, just repeat the process and adjust again to: LN:220V / LL:380V (AC) ————————————————————————————————————– Warranty and support – WccSolar All these settings and tests have been verified by the WccSolar after-sales technical team.
