Yes, rather replace the car than live with a complex machine that has been rebuilt.

Aw, don't fret, Koebelwagen told me where to get a CZ 550 Safari Magnum in .458

On second thoughts, a B/B gun will do.

I would have shot the taxi driver. >:D;)

Pity, I suspect the 5 speed boxes may be more available.

The 124ST was also 5 speed.

Was my first car. Was also one of the first commonly available cars in SA with 5 Speed, DOHC, Disk brakes on all four wheels.

The only time it will indicate 20V on the charger is when there is no battery, or the battery is 100% charged, AND there is no load drawing current.

Look at my signature. Both current in daily use.

TDV8 open road, 10-11 l/100km - around town 14-16 l/100km

It is working exactly as it should.

When you measure the Solar Panel voltage with the solar wire removed you are measuring the panels Open Circuit (OC) voltage. The moment you connect the panel...

There is a big difference between a domestic DB board and an industrial control panel.

SANS 10142 Part 1 (Wiring of Premises - Low Voltage installations) requires that all Low Voltage Switch Gear...

Really dunno.

Some problems I see. No indicator of status/switch position. Breaks the rule of top connections are input, bottom connections are output. No SABS/SANS approval.

IMPORTANT- no icu...

That is an excellent device for smaller "wired" solutions.

Unfortunately it isn't Din Rail Mount, which makes for a rather messy installation in a DB. It may also be "illegal" to install in a DB.

Perfect.

Now automate you changeover using the electrically operated contactor version.:D

Hagar Part No. ESC 442

Exactly. I would kinda assume and switch masquerading as a mains change over would be the right configuration, but I would make double sure with a relay.

Don’t bother switching the Earth. Just common it to all three.

Be carefull with the changeover switch, try and do changeover with no power on.

Much more likely to be brushes than faulty armature.

That was amazing. Thanks.

I think one would have to differentiate between a low voltage cutout, and cutting out because of low voltage. Similar outcome, but very different cause.

Same concept as a motor running out of revs...

Without a doubt, there are a good few true deep cycles on the market. Virtually every manufacturer has at least one.

However, the market is screwed up by a great many borderline technologies and...

Not easy as far as I can see.

More importantly, illegal, even with a fancy automatic contactor to switch circuits. Any switch system would need to be designed by an engineer and certified, which...

If you alternator does in fact maintain 14.5ish Volts all the time, then it would appear that you can use the Cyrix to good effect. Go for it, I am sure it will be fine. No point in getting hung up...

It’s rather difficult to generalise with batteries and chargers.

Smart chargers, either alternators, or otherwise, obviously differ in how they work.

Suffice to say, some may not be smart...

Hi, that is a pretty dangerous article, and is typical of "vendor" based advise.

Now, you get Smart alternators and Smart alternators.

--------------------------------

Your typical original...

14.53V makes it a smart alternator.

I believe it is worth a punt.

Obviously a second use battery, so I wouldn't use it for a home solar system, but for sure I would for a camping solar system.

Pics, or it didn't happen.

Best advise I can offer - leave well alone. Unless the CAT's are actually faulty I cant think of worse costs/benefit ratio mod.

No, I am referring to using a Solar Panel that is large enough to force a 5V drop across the 1 ohm shunt, so that the Arduino can have it's full A/D input range to work with.

You have two choices,...

Something to consider - a 200AH battery is almost impossible for even a young fit fellow to carry more than a few meters. You wont lift it onto the back of a bakkie or a shelf.

Two separate...

Exactly - well said.

Yep, agree.

Selecting the resistor will be a bit tricky. 1 ohm will probably not work for any panel. On a small panel the voltage across the resistor will be to small for decent readings, and if...

Oops, one extra Zero, so 1.4kWh.

AH is only half the story and tells you close to nothing. When somebody quotes AH it is meaningless unless you also quote, at what voltage.

Unfortunately we...

Here's a thought.

The Jackery is about 500Wh and the Lithium 444 is about 400Wh of stored energy.

A Blue Nova based system would be about 12000Wh of energy.

Makes you think, doesn't it.

Eish, some of us can get away with less.

When buying for a lifetime, the older you get the cheaper the goods can be.

One of the problems with these issues is that people think they are islands and exist for themselves.

The examples and reasoning offered are fine and relevant for one home, or a few homes.

Really neat. You should market those. With the big boys in the USA and UK.
