It's free advice... and you get what you pay for
Hi Pat,  You can take this with a grain of salt, as I have only a passing familiarity with the inner workings of the H26.  From the way you describe your needs, there seems to be a simpler solution.  I think I would run a heavy duty (marine grade?) extension cord from the dock to a 15-Amp recepticle mounted in the cockpit, on the side opposite the walk-through opening in the transom. The recepticle is available at West Marine, and is marketed as a "Battery charger inlet" (WM #191991, $16.99, pp484 of catalog).  Into the back of the inlet, I would plug in a heavy-duty power strip, with a built in circuit breaker. I would probably mount the outlet strip somewhere near the galley.  At this point, I have two options:    a.) Plug in the battery charger in the galley, and run the battery charger's power cord through the appropriate bulkhead or wiring channel, or  b.) put an outlet splitter on the back of the power inlet, and plug the power strip in one side, and the battery charger into the other.  To isolate the charger from the solar panel, I would probably install a switch in the positive lead from the solar panel to the battery, allowing you to disconnect the panel while the battery charger is plugged in.  I would locate the switch near the power inlet, to help me remember to disconnect and reconnect the panel when using shore power.  The battery charger you select is also important; The "maintenance chargers" generally put out about 0.5 Amps, and are useless if you plan to run any loads on your system.  I would recommend a 'smart' charger which charges at 10-amps "bulk" to meet your needs.  It's not the most attractive setup, but it would be effective, semi-permanent, and much better looking than just running an extension cord through the companionway.  It could also save you a chunk of $$, over having internal wiring and receptacles installed.--Jon BastienH23 '2 Sheets to the Wind'H25 'Adagio'
