help on solar charge controler

[javadz]

hello,
i have many questions about solar charge regulator
suppose i am talknig on a solar charge regulator like "Steca_Tarom4545-48"
first :how solar charge regulator can protect the battery from surcharge or overload when we connect an inverter on battery in stand alone system?
for a regulator with dc output ,normaly it disconect the charge that is connected on it but with the charge that is connected with battery ,how?
second how it disconect the pv generator when the battery are overload? do we must use relay?
third,an mppt charge regulator like vectron blue solar 150/70 have only pv in and battery in,did it protect battery from surcharg and overload ,or it only charge the battery ?

excuse me for my bad english and all this questions
thank you

--- Mod Note: Please do not ask the same question in two different places. It causes confusion and makes it more difficult to give the best answers.
I have merged your two threads.

A solar Charge Controller ONLY controls the charge from the solar panels, to the battery.

If you hook something else to the batteries, it too, has to be configured to not overcharge the batteries. Or overly discharge them and ruin them.

You should use quality gear, that you can take back to a store if it does not work properly (according to it's spec sheet, not your desires).

A normal solar charge controller can only regulate its own output so that the charging current and battery voltage do not rise above the programmed limits.
It does this by cutting off its own output, so if there is another charger connected that is trying to overcharge the batteries it can do nothing to prevent it except refuse to participate.
There is another kind of charge controller called a shunt or dump controller, which might be able to shunt out the output of the other charger too, but such a controller is very wasteful and also has to dissipate a lot of heat in the process. You rarely see shunt controllers these days except for wind or water turbine systems which do not like to work without any load.
