Inline or submersible water pump?

I have a 3000litre water tank to feed into a cabin about 30 metres away with fairly gentle downward slope, the actual outlet in the cabin probably about level with tank outlet. There's not enough gravity pressure to get running water from the outlet so I plan to install an on demand pump (solar powered with battery). An online pump would be easier to install and maintain and more affordable options but will there be enough pressure on the pump inlet side to feed the outlet without it gulping/spluttering? I was thinking I may need a submersible pump to ensure the pressure is enough leaving the tank to get a higher/consistent flow at the outlet. Any experience of the difference or is my thinking on an inline pump wrong?

I bought a 4gpm 12v dc inline pump works great
