I've got 198 watts of flat mounted solar and 90Ah of battery and my battery would be significantly happier with 300+ watts.
Any charging is better than no charging but a reliable system that yield excellent battery life, needs more than just whatever.
when designing a system, work withing the limiting factors. 400 watts can fit, then tailor the battery capcity to that, and regulate the loads to within their capabilities.
If the loads exceed their capabilities, then one can perhaps run engine while running the induction cooker so the alternator is powering most of it.
When Solar is to be the main or perhaps only charging source, you cannot have enough.
So Jim's answer of " how much roof space is available? is the most succinct and accurate.
