4.4. Programmable relay
The inverters are equipped with a multi-functional relay that by default is programmed in the normal operation mode. The different
relay modes can be summarized as follows:
Inverter (default setting)
Relay closed during normal operation, and opened when the inverter has switched itself off in alarm, has been switched off by a
user and also opened (of course) when there is no power available on the terminals, ie. battery disconnected. In ECO mode, the
relay will be closed both when searching for a load and when fully on, ie. load detected. Use this option when you want the relay
to signal that there is power available on the output of the inverter.
Alarm
As above, but then the relay also opens when there is a warning. For example because the battery voltage dropped to the cut-off
value, or when loaded to the point where it will almost shut down due to overload. In ECO mode, the relay will be closed both
when searching (no load) and when fully on (load detected), except when there is a warning.
Use this option when you want the relay to signal that it is time to do something (charge the battery, reduce the load, and so
forth), in order to prevent a power outage.
Low battery
Relay on during normal operation. The relay will switch off once there is a low battery warning. It will remain off in case the
inverter shuts down due to low voltage, and will only switch back on again once the inverter is operational and the battery voltage
is above the pre-alarm reset level. Use this option for load shedding, or to automatically start a generator. Note that this can only
be considered a poor-mans generator start/stop. For more and better options, see the
Fan
Relay is off, unless the fan inside the inverter is running. Use this option to switch an external fan, for situations when the inverter
is in a small enclosed space.
Off
This option sets the relay in the OPEN position. Use this option if you do not plan to use the relay function.
4.5. Firmware update
The firmware can be updated in the inverter product settings:
• Navigate to the inverter settings by clicking on the cog symbol in the right top corner.
• Click on the 3 dot symbol in the right top corner.
• Choose "Product settings" from the menu.
• The firmware section will display the firmware version and a button to perform a firmware update.
