ERA5 Land Surface Solar Radiation Downwards -- extreme low values

We have downloaded and are using SSRD from ERA5 Land. We downloaded the data at 00:00, divided it by 86400 as advised and timeshifted to fit it to the previous day. Thus far we have daily values for 1981-2020. However the values are extremely low! Please see the plot below.

Please advise what we are doing wrong..
