You have my sympathies, but unfortunately all nad cases are completely automated so ebay will issue the refund unless you do it voluntarily.
All I can suggest is you wait till you get the generator back, and if it is damaged as you suspect, speak to ebay customer service before refunding and explain clearly and calmly what has happened. If you have messages in your inbox proving the mistake is the buyer's, so much the better, ebay can read them. so keep all messages.
Explain that the item has been damaged by the buyer and is no longer in the same condition it was received, so, under ebay's own rules, does not merit a full refund.
See what they say.
