A solar charger employs solar energy to supply electricity to devices or charge batteries.



Solar Controller does not completely define what it is or does. The better term in our case is Solar Charger.



By definition a solar charger is a battery charger but a battery charger is not a solar charger.



It's the same as "a square is a rectangle but a rectangle is not a square".

Ditto

This is what the Tristar T45 Solar Controller does:
Morningstar’s TriStar™ is a three-function controller that provides reliable solar battery charging, load control or diversion regulation. It is rated at 45 or 60 amps, both at 12-48 volts, and has an optional meter, remote meter and remote temperature sensor.

Seems to tell me what it does.

I have not described my system, so I don't understand your " mine is better then yours " comments.

My point was to show others, who don't have or find battery monitors "to complicated", how important they are to battery management.

Another important part of building a solar charging system, is to do an energy audit, so the designer isn't wasting money, over building a system.

Enjoy your day.

A legend in his own mind. What asinine arguments, but stupid is what stupid does. These know it all blow hards mostly contribute their ego to the discussion. Arguing minutiae and semantics, and cut and paste, doesn't help people.

Do you even have a solar system or are you just being argumentative? Did you install it yourself? Have you ever used a solar system?

No I just think it's rather funny that some on here write comments that pretty much are nonsense and when asked a simple question reverse it and answer affirmative. Oh, that's you!

You have a solar system and so do do use your "charger" or a solar controller to charge it? What brand is this "charger"? Did you install it yourself?

Input voltage has nothing to do with defining a charger. There are DC to DC chargers and AC to DC chargers and they are all called chargers.

A Solar charger is a DC to DC charger.
The charger build into an inverter is a AC to DC charger.
The alternator in your car is an AC to DC charger.
The old generator that used to be used in cars was a DC to DC charger.

A Solar charger does have one special ability and that it can pull the optimum power from the solar panel.

So why not use the iota as a solar controller?

Solar amp hours in real life

[QUOTE=Timon;2739115]Input voltage has nothing to do with defining a charger. There are DC to DC chargers and AC to DC chargers and they are all called chargers.



A Solar charger is a DC to DC charger.

The charger build into an inverter is a AC to DC charger.

The alternator in your car is an AC to DC charger.

The old generator that used to be used in cars was a DC to DC charger.

A Solar charger does have one special ability and that it can pull the optimum power from the solar panel.[

"Input voltage has nothing to do with defining a charger". Then you proceed to define 4 chargers via input.

Don't you mean current type, AC vs DC? Those darn adjectives again.

So a 12 amp Solar charger using your phraseology can pull optimum power from a 1200 watt series of 17v panels and that's it?

So what's a good solar charger for my RV? I'm not familiar with any.

Ok, you have sunk to making doppy comments in the conversation.

I apologise for my attempt at a correction of your condescending comment to jackfish.

I'm sure your attitude will draw in all sorts of people, looking for your help in solar systems.

Enjoy your life in the desert, under ?10 hours of high sun, recharging in 2 hours, the 12% of your battery capacity, that you use each night living under a few LED bulbs.

I'm not impressed. I'm out.

Or maybe because you charge your batteries to 14.6v vs. the recommended 14.8v, big difference between the two. Oops, maybe I used the wrong verb or adjective or pronoun here, oh well.
