No, definitely not AQUAIR, definitely AMPAIR.

Ampair Wind, Hydro and Packaged Power specialists +44 (0) 1258 837 266 | Ampair 100

My peak current usage tends to vary a lot. Eutectic fridge runs to about 8A but I only turn it on for 2-3 hours per day. Portable fridge/freezer tends to run as a freezer on long journeys, I think that consumes about 40Ah/day. The next biggest draw is the autopilot, about 90Ah/day if I'm on passage where it's required (I also have a smaller draw autopilot and a windvane which draws zero, so it's an either-or thing). Other electronics about 15Ah/day, so I'm guessing my total draw is about 90Ah/day without the autopilot but maybe up to 150Ah/day with it.

I have 210Ah @ 12V worth of batteries, Trojan 105s.

Currently I have one solar panel @100W and the wind gen @ 100W so I do have to run the engine a bit to keep everything going if I'm doing so at full load. With just the small fridge unit running as a fridge, no eutectic unit, and no autopilot I can sit around at anchor indefinitely without needing to run the engine -- all of my water pumps bar one are manual, and I have a manual head pump and low wattage LED lighting throughout so I'm reasonably efficient.

Default Thanks, Need a little more info here!

Hi delatbabel,
The one thing I don't want to be doing here is to assume, as to how many batteries you have and what you do with them and how you are maintaining them. However, this is one of the most important area's of a good life of a battery and how well it will supply you the ever-lasting Ah's in it’s lasting battery life. So many people think that typically, if we put into our battery a 50% of charge then we get 50% output back out. This is typically not the case. There is many factors to take into consideration here.. and that’s why I’m asking the questions. The answer to this is typically 50% out or typical to 25% given under perfect conditions.
So to help you better understand what you need we need some more info as describe above. Of course, I could just add up the number's and say your taping your supply too much and you need to add more battery's or even 2 more wind generator but that's cheating and expensive and just not adjusting the sail's.. so to speak.. In a weekend boaters way "Through more money at it!"..LOL
So please! help me help you. Example: How often do you charge with and without any electrical systems applied or Attached? (engine,cell..etc). Do you use an circuit isolation switch to charge your batteries? Do you do any battery testing? If so how often? Do you do any desulfation and how often? Do you also equalize your battery's if so how often and how long? What type of charger do you have Programmable or non ? How is your charger wired to the Battery's (example? I have 2- 100 Ah battery's connected in series that give me theoretically 200 Ah. My 1st. 6v battery it’s + is connected to a house bar for 12vdc. The ground or – neg. side is tied to the next battery + side of the next(2nd) battery. on second bank one..etc) When your charging you battery's do you run your electronics while charging? if so what and how much Amp’s draw at that time?
Below: This is a sample of how to equalize from Trojan that’s your batteries brand. The funny thing is they call it “Equalizing”.
1. Equalizing “is” an “overcharge” performed on flooded lead acid batteries after they have been fully charged. It reverses the buildup of negative chemical effects like stratification, a condition where acid concentration is greater at the bottom of the battery than at the top. Equalizing also helps to remove sulfate crystals that might have built up on the plates. Note: If left unchecked, this condition, called sulfation, will reduce the overall life and capacity of the battery.

Many experts recommend that batteries be equalized periodically, ranging anywhere from once a month to once or twice per year. However, Trojan only recommends equalizing when “low or wide” ranging specific gravity (+/- .015) is detected after fully charging a battery.

Step by Step Equalizing:
1. Verify the battery(s) are flooded type.
2. “Remove all loads” from the batteries.
3. Connect battery charger.
4. Set charger for the equalizing programmed voltage.
5. Start charging batteries.
6. Batteries will begin gassing and bubbling vigorously.
7. Take specific gravity readings every hour.
8. Equalization is complete when specific gravity values no longer rise during the gassing stage.
NOTE: Many chargers do not have an equalization setting so this procedure can't be carried out.
This is a start anyway. Thanks for being patient here. This some times becomes a little involved but at the end you’ll have less headaches trying to figure out why.. to more power less expenses for replacement battery’s and stocking a lot of parts$$.
Happy Winds
Capt. Rob

Have now had a Eclectic Energy D400 for 2 years. Excellent, quiet, robust, machine that produces heaps of power. Needs a solid mount as the thing weighs 17 kg. Wouldn't have anything else.

Rob, all useful information but I have all of that. This is about upgrading my current wind generator, not replacing the battery system.

Uesful info, I was actually considering their DuoGen unit because it can be easily converted to a water generator while on passage. Saves me having one of each. Where did you get yours from? They appear to have Australian dealers in various places.

I tried to buy from a local dealer and was quoted $3800 delivered to Hobart. I dealt with D400 Wind Generators | Furuno Fish Finders | Marine Battery Chargers and paid $2400 delivered to my door, even after paying duty and GST. Have been able to source spares from them since - very prompt and efficient.

The main problem with wind generator noise isn't the generator itself it's just the blades.... it only takes a few ounces out of balance to cause significant turbulance at high speeds, which is where the noise comes from. You can buy lead take for almost nothing at some hardware stores, if you balance the blades with lead tape, so that they are pretty well perfectly in balance it will go a long way to silencing your wind geny.
