Charge battery on overnight cheap rate

How do I get my system to charge my battery on the cheap overnight tariff?

MurrayTD1 if you're using the app, go to the cog (top right) > Charge Mode > Solar + Grid > back > enter your chosen start & end times, charge up to % and charge power. Hit save and wait for a confirmation message, if you get a timeout, try again.

I just use the app settings.

If you're using the portal - select the computer screen ion (My Inverter)It will display a row of options - select "settings" . You should see that your "ECO" setting is enabled. Leave this alone and select "Timed charge "Enter your start and stop times and use the slider to pick what % you want the battery to hare up to. Toggle the button from "disabled" to "enabled" then press "submit". You should get a green banner across the bottom of the screen showing your changes were accepted. If it comes up red, it didn't take properly so just press submit again
