Solar Catamaran, EV motor controller

[yabert]

Another contender: Flipsky FSESC 75450 84V High Current 450A
Really super affordable (strangely affordable) despite been 1200A peak and watercooled.
Seem serious as each group of 3 wires are 8awg (roughly 2AWG / 25mm2 equivalent)

Any thought?

The more I search, the more I find interesting controller: TRONIC X12 24S
Probably not powerful enough for my needs (5-15 kW continuous at 58V nominal), but nice!

It's seem to be based on VESC and design look good.
