Whenever I see a survey report I go straight to the
electrical system as that section tend to inform on thoroughness. This one leaves some questions.
Does the panel have a polarity indicator ?
Are AC and DC on the same panel ? If so is there physical separation ?
Is there a
galvanic isolator ?
Is there and RCD ?
Is there an ELCI ?
Are the neutral grounds bonded ?
Is the AC ground bonded to the DC ground ?
Is there
lightning bonding ?
Are underwater metals bonded ?
Are the
batteries in electrolyte resistant trays/boxes ?
Are the
batteries fuse protected ?
Are the inverters chassis grounded ?
Is the water
heater also connected to
heat exchanger ?
Are
stove burners fitted with thermocouples ?
In photo#6 there is a piece of
equipment with what appears to be a ground lug with no ground wire attached.
