Sorry just see your reply. Mustek stock them

There is some very poor advise above re batteries,  I would also stay well away from Growatt inverters. We have a plus 10% failure rate on the Growatt units.
For a 3ph solution I would recommend the Sunsynk or Deye 12kW units.

The C10 rating is 167ah

Yes has a cover. At this stage not too worried about overheating, all the main vents are open. Will monitor it.

Love it. Make a plan

Two ways to test. Put a volt meter on the PV side while it's in operation. If it's MPPT, input voltage will be over 50. If it's PWM, it should pull down to battery voltage. Second way: put an ampere meter on the output (between inverter and battery). Remove all loads from inverter so you are only charging and turn it on. If it's an MPPT, it will make 480/24 =20A (to make the math easy) on the output, in full sun. If not, given that the panels are sitting at 70V, it will make less than 10A.
There is also the trick where you hold an AM radio that's off-tune next to the wire, and it should make a buzzing sound, but I think that test is to test between PWM and the switching types.
