Don't you find it tiresome/wearing/plain noisy having the engine running for so much time moored up? Or do you mean you cruise 1 to 4 hours a day? In winter I charge for an average of 2hours a day, but this average is over the week. It tiresome which is why I recommend to anyone living off-grid to seriously look at a built in diesel generator as these can be made "hardly noticeable". 1 Link to comment Share on other sites More sharing options...

If separates then the charger can be wired direct and the inverter through the existing isolator. Both fused of course.

I'd say "can be" not "should be". Ours doesn't have a dedicated isolator and I've never seen the need for one. Arguments for an isolator: "what will you do when the inverter goes in fire and the fuse hasn't blown?" Arguments against an isolator: "the device is left connected to the batteries 24/7/365, on shore power charging when the boat is unattended. If the inverter does go on fire without the fuse blowing, the probability of there being someone handy to switch off the isolator is very small. The probability of that person having the wherewithal to move in the opposite direction to the natural urge, brave the toxic smoke and switch off the isolator is minimal. So what's the point?"

However a sharp-eyed BSS inspector might not No I disagree, the BSS allows for chargers and other devices designed to be permanently connected, to be so connected. Our Combi's installation instructions shows it connected direct to the batteries (via a fuse) and it is thus installed in accordance with the manufacturer's recommendations. All Hudsons are wired thus (with one or two exceptions at owner's request) and I've never heard of a BSS issue with it. Link to comment Share on other sites More sharing options...
Robbo Posted April 10, 2017 Report Share Posted April 10, 2017 With the cheap isolators you see in use on boats they would make matters worse if they had a Combi going threw them! Link to comment Share on other sites More sharing options...

Just for clarity, here's the BSS list of items that don't have to go through the isolator, and it specifically mentions inverter/chargers, ie Combis.

Its all a compromise isnt it though you knacker your batteries by not charging enough whilst I wear an engine out quicker though I doubt I will need to change it. I have an ultra smooth very quiet engine and you probably have some noisey old fashioned clunky crap? My bro in law has a noisey crappy old engine but uses a Honda silent gennie to charge his batts but it aint realy that silent.

Depends entirely on what you intend use it to power! It seems you can choose between the 2200w or 3000w ones. What the most power-hungry appliance you want to run? And remember that if it involves a motor, the actual peak power needs may be significantly greater than the badged consumption. Link to comment Share on other sites More sharing options...
Dave Payne Posted April 10, 2017 Report Share Posted April 10, 2017 am i being stooped, why would the op need a charger if he has no shore power? Solar and wind connect to batteries? Link to comment Share on other sites More sharing options...

Well I have the Mastervolt 2500/100 which is a 2500 watt inverter and 100 amp charger. That model is discontinued now, but a look at their website will show their current models for you to choose from. Link to comment Share on other sites More sharing options...
