Western WI400-12 Inverter 400 W 12 V DC
General Description
WI400-12 and WI400-24 are DC / AC inverter, designed for off-grid applications, with high reliability and professional performance.
The product was developed to produce a waveform of pure sine AC output, with high conversion efficiency, up to 90%, and very low power consumption in stand-by mode, less than 2.5W.
These features are obtained through a hybrid configuration with toroidal transformer output and high frequency switching technology. (HF Technology)
The energy saving function allows to reduce the consumption in a significant way in the event of lack of the connected load, ensuring a superior system autonomy.

WI400-12 AND WI400-24 INSTALLATION GUIDE
-
BATTERY CABLES: the WI400-12 and WI400-24 inverters have to be connected to the battery with cables with a suitable section, in particular in the case of distance between the inverter and battery less to 1.5m or more but in any case within 3m, according to the following table;
-
BATTERY CONNECTION: configure your battery bank with voltage 12V for WI400-12 model, battery bank 24V voltage for the WI400-24 model, then connect the RED terminal to the POSITIVE of the battery and the BLACK terminal to the NEGATIVE of the battery; (WARNING: if you do not respect the polarity the inverter will be damaged permanently!)
-
AC CONNECTION: Connect the AC load user with 230Vac output, through SCHUKO standard connection; (CAUTION: Never connect the output of the inverter to another AC source, such as the electricity grid or a generator!)
-
POWER ON of the INVERTER : set the power switch I-0-II in position I [ON], perform the startup of the inverter and check the power supply of the user load; (WARNING: in case of overload for 3 times within 30 seconds, the inverter goes into automatic shutdown, for the restart is necessary to turn off the power switch, remove the cause of overload and provide with a new power on procedure!)
-
POWER ON of the INVERTER in ENERGY SAVING MODE: set the power I-0-II position II [ECO] switch, the power saving feature enables a reduction in power consumption in stand-by 70%, through the activation of the inverter for a short period every 2.5 seconds. The inverter switches to an activation status always ON for a load with more than 30W while turns into a energy saving status for a load with less than 20W;
-
RENEWABLE PLANT: if there is a plant of renewable energy production, connect the plant through a dedicated charge controller on the battery terminals. (WARNING: WI400 inverter battery cables should always be connected directly to the battery terminals!)
-
REMOTE ON / OFF: connect a remote on/off power switch to the dedicated connector with 2 poles removing the series closure jumper. (CAUTION: even the power switch must be set to ON or ENERGY SAVING)
MEANINGS OF LED INDICATIONS
Table of LED STATUS and LED ERROR warnings
LED STATUS
| GREEN LED ON: normal working status activated ON.
LED STATUS
| SLOW FLASHING GREEN LED: working status at energy saving ON.
ED STATUS + WARNING
| GREEN LED ON RED ON: forthcoming shutdown due to OVERLOAD.
ED STATUS + WARNING
| GREEN LED ON RED SLOW FLASHING: forthcoming shutdown due to LOW BATTERY.
ED STATUS + WARNING
| GREEN LED ON RED DOUBLE FLASHING: forthcoming shutdown due to OVER- TEMPERATURE.
LED ERROR
| GREEN LED OFF RED ON: inverter shutdown due to OVERLOAD.
LED ERROR
| GREEN LED ON RED SLOW FLASHING: forthcoming shutdown due to LOW BATTERY.
LED ERROR
| GREEN LED ON RED DOUBLE FLASHING: forthcoming shutdown due to OVER- TEMPERATURE.
LED ERROR
| GREEN LED OFF FAST FLASHING RED: inverter shutdown due to OVER-VOLTAGE BATTERY.
WARNING: in case of LOCKED inverter, there is no supply voltage at the output AC-OUT, because occurred of one of the FOUR fault conditions specified in tab. 3, you need to RESTART the device, according to the following sequence:
- turning off with switch in position 0 [OFF]
- wait for 2 seconds
- new turning on with the switch in position I [ON] or II [ECO]
