I agree redundancy and backup is good. If you read Nanni's literature, per the link, you'll see their Intecalated Hybrid concept gives good backup as the in-line generator can also be driven by the propellor with the engine off - much like the Santorin shaft generator.
So for battery charging you'd have 1. the conventional engine battery alternator, 2. DC output from the 2.4kv Intercalated generator being driven by the engine (it puts out both AC and DC), 3. same as 2 but driven by propellor while sailing and, in your case, 4. your solar panels.
And you can maneuvre under batteries alone! How cool is that! I rather think we'll see the industry continuing to go in this direction - Amel may be lagging a bit. Backup needn't be old technology, except for guys like me who hug their engines and keep 'em running forever.
Will keep a lookout for you this season in Turkey as we may head north from Didim past Kusadasi.

You are absolutly right, the Nanni product line is proofed as a quality product and a well known name in the
marin industry; less in the US then in Europe.
But in my long time experiance with Amel, the aim of Amel was and is
always to have a backup system. If the main engine fails, you don't have again 220 V and no auxiliary system for
charging the batteries.
For example, I have on my SM #16 3 ways to charge my batteries ( and this is in my opinion the
first goal of a concret energy system); Alternator 24 V 95 A on the main engine, Genset via charger 220V - 24 V and on
the genset a 75 alternator 24 V. Additional I have installed 4 flat solar panals on the deck with 300 Wp at 24 Volt.
That gives me an average of 2 to 3 amps at 24 Volt. Not for charging the batteries, but to slow down gen set hours if
we have sun. Of course there is still the shore power if laying in a marina.

On the other hand......
take a look at Nanni's
Intercalated Line, with a 4.5Kw variable speed generator inserted in the drive line of the Kubota engine. Here's a
link to a brochure showing it in an Amel.
Nanni is (now) a
French company - interesting that they feature their product in an Amel - I wonder if they may be talking to Amel -
heard anything, Joel? I've often wondered why Amel hasn't moved into the hybrid eco-trend - maybe they are now.
We've got a 4.5Kw(6Kw@110v) Northern Lights Genset with a Kubota engine and both that and our Perkins have about 7500
hours on them. The Kubota has been absolutely bullet proof. I would definitely put the Nanni Hybrid system on my list
to carefully evaluate when I get to the point of repowering, replacing both genset and propulsion engine with one unit.
Of course with Kubota's reliability that's a long way off :-)

would be your experience?
We are thinking to buy a new motor for our Super Maramu does any one has a Nanni?
Than you ,
