Re: Underwater Lights that screw into through hull

If the vent is below the heeled waterline it is below the waterline.

Re: Underwater Lights that screw into through hull

Like the Lumitec Seablaze at about $300 each.

I also would not mickey mouse the installation - remove the through hulls, enlarge the holes as necessary and install them properly.

As cool as...

Re: Inverter Dying?

On any properly wired AC circuit neutral and ground will not give you 120 volts. Hot and ground will as will hot and neutral.

120 volts between neutral and ground shows reverse polarity.

All AC...

Re: Inverter Dying?

In addition the positive bus in the picture isn't covered.

I have seen inverters fail when one of the 2 DC leads melted while the other looked perfect - not that rare at all. In one case I was...

Re: Inverter Dying?

How long were the wire runs - positive plus negative? What gauge of wire was used?

Re: Cable Size

The link is to a North American calculator so the distance is in feet - east to tell really as the wire is notated in AWG not mm2.

Re: State of Charge

It will remain accurate, more so as it learns your system. Amp counting monitors - Xantrex, Victron, etc - will lose accuracy over time as the battery capacity diminishes.

Re: Help sourcing IP69 shore power inlet

I have not heard of one and doubt you will have any luck. One solution is with the shorepower cable entering the interior through a waterproof gland and hard wiring it in. The cable would have to be...

Re: Any differences between Xantrex LinkLITE and Whisper Power Battery Monitors

I have not heard of the Whisper Power, but they look the same to me except for the name.

Tha Victron meters are excellent as well, and may be a better value depending where you are located.

Re: Cable Size

Use series only if there is zero chance of a shadow on any of the panels. In other words with 3 panels on a boat use parallel as there is bound to be some shading, however small. Series doesn't work...

Re: Putting it All Together - Excederin Headache

Re: Inverter Dying?

If a hired electrician gave that as a final answer he would be fired. This needs to be checked with a meter at the inverter when it is in use.

Also you posted "Link monitor reports 12.8 or even...

Re: Shoestring Sailors (Cruising on $500 per month - part II)

I agree 100%, but w1651 is installing electric drive - a mistake for anyone not plugging in regularly. Definitely not the way to be self sufficient.

There isn't enough space on his boat for the...

Re: Interconnecting/Bus Bar Battery Cable Lengths - Some Closure

While it is actually a bit less I figure 10% for inverter draw - 3000 watts = 300 amps at max output.

4/0 would be my choice as well and I would try to keep the wire run short.

I would fuse at...

Re: Solar and AGM'S

You fuse for a dead short at the battery. That is the dangerous source. See ABYC.

Re: Solar and AGM'S

There should not be any voltage drop in a charging circuit.

If a controller is set at 14.4 you want all of that voltage to get to the battery post. Mainesail posted the numbers once concerning...

Re: Solar and AGM'S

I would install the controller close to the batteries and use large wire to eliminate voltage drop. Ideally you do not want any drop in charging circuits. Fuse size should be the largest possible for...

Re: My 12v set up

The ELCI you have is 120/240 - model 3404 I believe. I would, if I was to keep it, wire it for 120 volt/50 amp and buy the shore power adaptor from 30 amp to 50 amp 120 for the many times it will be...

Re: Tool recommendations

Flex drive is for a rotary Dremel and I agree get one.

A multitool is different - uses blades that move back and forth.

Re: Tool recommendations

Robertson screws are a better choice. Nothing beats being able to place the screw on the end of the bit without it falling off and less chance of a stripped head.

Re: Alternator does not Fully Charge the Batteries

Available AH is from 50% SOC to 100% SOC. Engine charging is not efficient after the batteries reach about 80% SOC as the last 20% takes a very long time - figure 6 to 8 hours - as the batteries'...
