Rather than using wirenuts I'd recommend crimped butt splices covered

If you don't fill that heat shrink with silicone first, there is
nothing to keep the water out. Heat shrink is far from water proof.

Understood, but the better grades of heat shrink have glue inside
which melts and seals things up.

I have used heat shrink with silicone in it for years over a soldered
connection. The wirenut thing was just an experiment but I have to say
it does work, with the advantage that you can open up and restore the
connection if you need to without any special tools. These are in a
water tight box so it is fairly well protected but you can bury these
things in the ground (essentially underwater) with up to 600 volts on
them and a ground fault interrupter will usually hold.

These are not your typical Ideal #74 nuts.

Personally, I just never quibble with a connection that's lasted 25
years. If it fails next year, let me know.
Then I'll tell you what you did wrong.
