We have 465 watts of solar on our roof (three 100 watt Renogy Compact panels and one 170 watt GoPower) and yet when I run the numbers using either Will or another site (can't use affiliates) both have my amps at 25 in parallel. We use 10 awg and it works just fine. Our roof is full though. If there was more room, plan to add panels in the future, and keep with parallel, I'd go with 8 awg.
400W of solar suggests 30A. Parallel 12V panels would require large wire to the controller vs serial panels at about 8A. For the OPs application 10 ga wire at 8A would be ideal, maybe even 12 ga. There are tradeoff factors for any installation.
