So, given that it's just some outlets, and not a supply to a mains distribution, with all that wattage, how would we normally use it? Seems this is really just a high-draw local unit, as opposed to the inverter as used in a boat's distribution setup. Did I miss something (either in this or the usual boat inverter setup)?

And, the answer to the question is: ???

Hi, Larry, and thanks for the thought provoking, left below for reference.
However, one snippet which I don't understand - can you elaborate? I doubt many here will be powering the shore power throughout the boat with the battery killing inverter, don't you?..... Battery killing inverter? Most of what I read these days suggests a static load of well under an amp, some are milliamps. Running any electrical device will kill a battery eventually if it's not got the power replaced (which we expect to do in spades, or, as you've noted, our own power company should be able to cope with extended periods of no-replacement) - how's this different? We have yet to decide about the capacity of the inverter we'll use. Likely the mikey or coffeemaker will be the biggest draw; I assume that will want something on the order of 1500w. I have a 1/3hp grinder/polisher and a skilsaw which might also have a pretty good startup load, so I'm thinking of 2kw as my "solution" to house power. As we next to never expect to be at shorepower except during haulouts (and even then, should have no particular need, with our solar and wind), we'll want to make our various outlets be both - inverter and shorepower. As we don't yet know how we'll use the computer and entertainment stuff, we assume we'll want to have our outlets available everywhere they are now, as well as some other places I'll install in the next few weeks. None of those loads are very big, of course, but running drop cords isn't my ideal power solution, even if they are in raceways. So, back to the question of central power (and switchability for shore power/house power) and what to do...

Why can't we just plug the loads into it? Plug the boat into it, if you like....just like the dock. Of course, you'd should install a transfer switch to keep you from feeding the dock into it, or any other inverter that doesn't have one. Most things on Lionheart run on DC. A couple of things that don't are the little microwave oven we paid $15 (new!) for and the laptop power supply and printer power supply for WEFAX charts at sea. For those, we have a 1KW Radio Shack inverter mounted right next to the battery switches inside the engine compartment over the monsters to keep the inverter fan noise out of the boat and the big cables to it to a minimum length. A length of #14 drop cord snakes its way through to overstuffed wireways to the nav station where I installed a 115VAC standard 6-outlet power strip to plug the various computer loads into it. A second custom drop cord runs from the inverter to a dual outlet in a handibox behind the microwave in the galley. I also ran a control cable from the power switch inside the inverter over to a microswitch mounted on a neat little plate in a hole at the nav station used by the former owner for something that needed filling. This gives the inverter remote control to switch it on and off. A panel-mounted neon indicator connected to the 120VAC in the nav station power strip lets me know the inverter is on and, in fact, producing 120VAC power. When the microwave is running, my DC clamp-on ammeter shows it drawing about 33A at 13.8VDC to heat dinner. Even at the dock, the microwave runs off the inverter. We plug the computer stuff into a shore-power outlet by the inverter's power strip. I doubt many here will be powering the shore power throughout the boat with the battery killing inverter, don't you?..... 3KW is way overkill because the boats can't provide DC to 3KW for very long.... |

Running any electrical device will kill a battery eventually if it's not got the power replaced (which we expect to do in spades, or, as you've noted, our own power company should be able to cope with extended periods of no-replacement) - how's this different? Do the math. Let's say we have a BIG inverter, 4KW continuous. This is great for TEMPORARY loads that need 4KW for a few minutes, like your coffee maker. But, as I jokingly put it, may boaters think they have their own "power station" when they buy one of these beasts. Case in point: 1500W heater - 12.5A@120VAC - about 120A at 13V.....x 24 hrs = 2880AH To provide for a simple electric heater and only drawing the battery banks down to 70%, not zero which destroys them....2880/.30 (30% of battery capacity) = 9,600AH battery bank. How big did you say those cells were?...(c; Hence my comment, "The funniest thing is to see a boater with a new 4KW inverter carrying his electric heater down the dock with that smug grin on his face." I've seen them incredulous that their 5KW inverter can't run the boat's air conditioner for the weekend anchored out. Math is not one of their majors...(c; We have yet to decide about the capacity of the inverter we'll use. Likely the mikey or coffeemaker will be the biggest draw; I assume that will want something on the order of 1500w. I have a 1/3hp grinder/polisher and a skilsaw which might also have a pretty good startup load, so I'm thinking of 2kw as my "solution" to house power. 2KW is fine.....for INTERMITTENT loads. As we next to never expect to be at shorepower except during haulouts (and even then, should have no particular need, with our solar and wind), we'll want to make our various outlets be both - inverter and shorepower. Hmm...5A from a big solar panel or 15A from a wind generator = 5X12hrs=60AH per day if the sun shines or 360AH wind power in a full gale 24/7. Not much of a real powerhouse, is it, huge batteries or small batteries... Plan on using the big alternator on the engine every day in this configuration. As we don't yet know how we'll use the computer and entertainment stuff, we assume we'll want to have our outlets available everywhere they are now, as well as some other places I'll install in the next few weeks. None of those loads are very big, of course, but running drop cords isn't my ideal power solution, even if they are in raceways. So, back to the question of central power (and switchability for shore power/house power) and what to do... The "drop cords" aren't laying around. You can use electrical cable if you like, wired into the boat. The inverter electrical system on Lionheart is wired into the boat and plugged into the inverter. As to powering the boat from shore and inverter, you install a transfer switch between the sources, ensuring the inverter is never connected in parallel with the power company from the dock. It's, essentially, a double pole switch, mounted in a box with a lockout so you can't run both, simultaneously. Any home generator transfer switch will work on your inverter system. |

We have a 1KW inverter and it suns everything we need. THe microwave is
the biggest load. Doug "Skip Gundlach" skipgundlach sez use my name at earthlink dot fishcatcher (net) - with apologies for the spamtrap wrote in message ...
