 Topic: Wire runs in coach roof to DC panelPosted: 01 June 2020 at 19:40 |

I'm planning to install 4x 65W solar panels onto the exterior fiberglass line covers of our H455, having already seen photos posted of this design on myHanse.com. To do this, the wiring for the port and starboard side solar panels will need to penetrate the coach roof and run down to the electrical area located near the port side navigation station. To that end, I'm am trying to locate a pathway or channel that would allow starboard solar panel wiring to travel across to the port side and then drop down to the house battery bank. Wondering if anyone has successfully accomplished this? I'm also seeking any information about how the interior fabric-covered headliner panels attached to the ceiling of the coach roof can be removed for this purpose?

I fitted a solar panel to my 418 (You may find some info on the 418 thread). I ran the cable down under the port deckhead from the corner of the hatch opening, around the heads bulkhead and then down the coachroof side by the window to the rear of the electrical panel. Dropping the recessed lights out allowed me to find routes. I used a USB endiscope and laptop. An alternative might be to route the wire fwd to the mast and then follow the route from the mast cables (you could probably even pull one out to pull a mousing line through - I did and have left a spare). I seem to remember access from one side to the other under the deckhead molding was pretty difficult due to lots of blobs of adhesive blocking the route

This was the route. As S&J said about dropping the light out by the companionway. Unfortunately I couldn't get the cable to turn the corner from the coachroof side to the deckhead as the angle was too tight, so I had to remove the pelmet for the blind, drill a small hole to ease the cable round. The Pelmet covers the hole once refitted. Hope the picture helps. Oh and I chickened out of pulling the fabric panels down. Mine were very secure and I suspect glued on rather than veclro or fastenings. Shame as that would have made everything a lot easier!

Thank you for responding so quickly. This is a tough challenge, so I appreciate any experienced input that can be gotten. Once I solve for our particular situation, I will what we end up doing along with photos showing the route that worked for us.
Also, I'm still hoping to hear from Hanse about how the ceiling panels are attached to the headliner, and assuming they respond will post what I learn.

Did you find an answer as to how the fabric panels are attached. My broker seems to think that they are velcroed but they seem a little more secure than that.

Love the details in the thread so far. I am about to run into similar problem with my new solar install for Aeolian. Would love to see updated pictures if anyone has them of how they routed their wiring and/or information on how to remove the ceiling panels. Best, Jared

Hi,
This is much easier than you think! Take the wires forward in the roof void to the salon forward bulkhead, then to port in the mast cable duct (removeble panel held by velcro) then back down the port side either at high level below bulwark or down past the holding tank (if fitted in salon) and back behind the couch. We ran four 6mm2 solar cables by this route in a couple of hours. We simply popped out the celing lights passing cables from one light fitting hole to the next. We used 6mm2 cable to reduce losses as this route is longer than a direct route but far easier to use. We used a borescope type camera above ceiling; the only route from ceiling directly towards electrical panel is RAMMED with cables and unrealistic to force any cables at all via that route unless Hanse changed the moldings on later models that is. Cheers. Edited by Ian Coverdale - 29 January 2021 at 19:25 |

It is if you are lucky enough to be able to go fwd. Unfortunately I found there was no route forwards available on my 418 (neither was there a dedicated conduit from the underside of the mast). My route fwd was blocked by copious grp tanning of the deck head to the coachroof. Not sure how consistently Hanse have built their models over the years, it’s of course possible different models or different boats within a model range may have less tabbing or for it to have been placed / squeezed differently during manufacture. Good luck everyone and be patient! You WILL succeed ;)

Hi Matt.
Yes of course it depends on the model. This query relates to 445/455/458. My experience was with a 445 which is identical in hull/interior to latter 455/458 however the deck moulding is different in many areas from cockpit to portlight layout so may be some different challenges there. I found a £35 borescope camera from Amazon invaluable in my explorations. Thanks, Ian. |
