Kind of like those who bought Yugos, or made them.

They probably warranty the rotor because it almost NEVER goes out in a brushless generator design.

The "hard" parts that fail on a generator end, (barring a bearing failure wich destroys the whole thing) are the exciter winding and the stator winding.

Thats because the exciter is subject to overcurrent from a failed voltage regulator, and the stator is subject to high heat and overloading from too large a load, too high ambient temperature, short circuit damage, etc...

The rotor is easy to warranty for life since it almost never fails.

You should have a lot of real estate on your Cat for a large solar bank, so why not fill it up with panels, and add a good sized LiFePO4 bank? Get a Honda 2000 if you want some insurance.
Granted, if you must have AC then you will need a genny. I deliberately chose to not have AC. I will use 12V fans. A bit of air circulation is all you really need.

I removed a 7.5 kW Onan and a 2.5 kW Mase. I do not have a genny at present, but will get a little Honda fairly soon. Here in Brisbane the sun shines quite a lot - my 1800 watt solar array seems to make more power than I use. My back up for cloudy days is 2 x 200 amp alternators, one on each of the main engines. For charging batteries that's quicker than a genny would do anyway.

That was the original plan due to genny cost
Then this one popped up for less than 1/2 the cost of a honda
If it proves to be reliable after an overhaul I have had a great result
If not, well its a relatively inexpensive lesson and I may have picked up some diesel skills

as mentioned earlier I don't want to carry the extra petrol required.
30 days worth for a 15hp outboard will be bad enough.

exactly

if you are only cruising the QLD coast I would probably agree.
I will be going and staying 2000nm further North than Brisbane again.

Why would you take out an already installed 2.5kva diesel to replace with 2kva petrol?

As a live aboard?
And with no A/c

I only have 100 x2, but I would rather not use my engines for charging

Is it?
They would have to both be running at full noise to get the 400 amps wouldnt they?

The Mase was a 3600 rpm salt water cooled unit. It was never going to be there long term, and took up valuable space. I had only run either genny once in six months of living aboard, and even then it was just to see that they did work. It seemed pointless to have them.

My solar is running two fridges. All my lights are now LED, so little draw. The microwave doesn't run long enough to use many AH. The washer and dryer are power hogs - normally use them when cruising somewhere. Not fulltime liveaboard, but think I'll have all the power I need without a genny. If I do get a Honda it will only be for remote trips and for emergencies, and possibly for easing the load on the battery bank if on the hook for an extended period and I have a laundry backlog. Its only the size of a battery, I can store it easily and just sit it near the shore power inlet if required.

My alternators belting/pulleys were sized to give good low rpm charging. I get 325 amp in total at 1000 rpm on the engines. At 1200 rpm I'm at 360 amp. I haven't seen 400 amp, not sure whether they do not do rated output or the charging circuit has a limitation. I'm fine with 360 amp. I have not run the engines just for charging.

Insequent, that is an impressive solar performance.
Two questions: what is your battery bank size, and, do you run the 2 fridges directly from the regulator(s) or via the batteries (presumably via a switch panel)?

How realistic do you think this system is, not that I would get it from there at those prices.

6 x 200 w panel
750 amp battery (boost up to 1000 of LiFePO4 )
Victron Skylla 50 Amp Battery Charger
Latronics 1800 Watt Inverter
Plasmatronics 40 Amp Regulator

They reckon it can run amongst other things, a 420 litre 240v fridge

My house bank is 6 Odyssey PC 1800 AGM's. Total capacity is 1284 AH, and rated for routine 80% DoD so a useful effective capacity. Although my 2 fridges and 2 freezers on the boat deck are all 120 VAC/12VDC I only run them on 12V. The power consumption is lower that way, both in the fridge/freezer themselves and in regard to losses in the inverter.

I didn't get it.

When the time comes it'll be solar and plenty of it.
It'll no doubt get even cheaper and more efficient and as far as a/c goes in reality I would probably only need it for a dozen nights of the year so a 2 or even 3kva Honda will suffice in those instances or maybe the Yamaha EF2400iS

I am not sure why I was thinking I would need it 365 days a year, if I did, carrying that amount of petrol really would be an issue.

Plan 2 sounds better, and avoids the FP imponderables. That land based system you mentioned seemed to be based on 200w 24v panels, not ideal unless installing 24v system.

Not even air craft carriers operate 365 days a year with out the fuel barge visiting.

Guys:

6 months ago I bought a Brand New FP 7KVA unit for $10.5K in Brazil after paying a huge amount of taxes. It circulates fresh water.
I still don't know how it runs but, I wanted a ONAN or a Kholer. not the FP. The thing is that the FP is spreading around the world like AIDS did.
It is probably a very profitable product to sell. Even in Brasil you can find them and they are not very expensive in comparison with wellknown reliable brands.

Potuguese
