Charger/Inverter Opinions . . .

On topic of charger inverter choices, would like to hear opinions on Xantrex and Mastervolt products. Are there other choices you'd recommend? For dock use and with Honda 2000 generator.
I appreciate your time and expertise.

Are you looking for an inverter or an inverter charger... they're very different beasties.

If you're looking for an inverter/charger, go with a Xantrex Freedom series. They're fairly bulletproof and very common.

It would help if you said what size boat you have as well as what size house battery bank, and what kind of batteries you have. This can all affect the recommendations as to which inverter/charger you should get.

Since you don't need an inverter with dock power OR a Honda Generator...are you really looking for a good battery charger that also has an inverter built in?
If so..how big is your battery bank? How many watts of inverter power do you need?

I am making the assumption you want a large inverter and charger combo, given the manufactureres you mentioned.

I have the Xantrex Prosine 2.0 Inv/Chg. Very, very good unit. Just a word of caution, if your are going to put the inverter close (CLOSE) to the batteries, you can get by with 4/0 cable - that is 0000, not 4 gauge. If it is more than (25 ft r/t... I think), you have to jump to 250 or 350 mcm.

Just so you know, I doubt 4/0 is what goes into your house. It is VERY large cabeling. I think west was selling it for $20/foot when I put mine in. I cannot imagine how much it is now. Incidentally, I did not buy it from them. I bought it from Cobra Cable. It has to be tinned, marine grade cable so your choices become a little limited. You will also have to order the lugs for them and find a place to borrow the crimpers for 4/0+ lugs. You also must know the post sizes.

It is not an easily do-able job for the average layman. If you do not have experience in the install of these things or a good electrical background, I would consider a professional install (that is bonded with insurance, smile). I bet the install will cost you more than the unit itself, though. But at 2000 watt run and an even higher surge, you don't want to screw it up.

Just my opinions.

Leave the inverter at the store. The Honda 2000 provides the AC, you'll only need a battery charger. If you are a weekender you only need enough of a amp rating to get you back in business after a week on the dock charging away. That being the case a simple 10amp from Mastervolt, the Honda and a 30 amp power cord will take you for years at a fraction of the cost, maintenance and headache of the killer "I can circumnavigate with this" setup.
