SA20 Connectors

Hi, can someone please tell me which pin is positive and which is negative on an SA20 connector, it's like the one that comes with the Bluetti AC200p. It does come with one which I need for solar connection so I'm making another one for the 25 amp output to run to a dc fuse block. The other output is only 10amp and with the fridge and lights on I feel that using the water pump will exceed 10 amps, is this true, do I need to use the 25amp output?
Thanks
