charge controler without dc outpout?

[javadz]

hello
i have a question
supose we have a charge controler without dc outpout(just pv input and battery outpout)
if a connect an inverter with the battery,now suppose the battery are fully charged,and the load connected with the inverter are running
and we have an ennough current from panels to run the load,
now ,from where the current will go to the inverter ,is ist from the panels through the charge controler or from the battery?
i repeat , the charge controler have not a dc outpout

Try looking at and rethinking what you posted - it makes no sense at all.

If the charge controller doesn't have DC output then what kind of output does it have?

Like Russ stated. Your post makes no since at all.

I think he's trying to express that there's no little lightbulb icon on his charge controller to hook things to. He's wondering if this will be an issue when his batteries fill, that the power will have nowhere else to go or some such.

Generally, modern charge controllers have 3 sets of terminals:

Battery

PV

and sometimes - LOAD
The LOAD is usually only for a very low power items, like a small LED light. really a pretty useless feature. The controllers can only manage a couple watts of load, or it burns out a part inside.


OLD style controllers (Shunt controllers) (Wind controllers) use a LOAD to regulate the charge going to the batteries, too much charge, turn on the LOAD to reduce it. The load is usually a bank of high power resistors, automotive headlights, water heater, something that will dissipate power.

The PV panels produce the current going to the controller and from there it distribute the power, it goes to the load (THE INVERTER) first and what ever left going to the battery. if the PV don't produce enough power to supply the load, the battery pump out the power to help.

Whether the CC has LOAD terminals or not, the inverter and any DC loads other than minimal lighting must be connected directly to the battery bus, not to the CC.
When the battery is full the CC will still provide as much current as the loads need. When the battery is full and there are no loads, the CC will simply not pull power from the panels. The panels are perfectly happy with that state of affairs, and can sit in the sun indefinitely while delivering no output. (They should not be left uncovered in the sun totally unconnected though, as that can damage some types of panels.)

thank you all for your responses, but i have a question suppose i have a charge regulator that give me 30A now,i have an inverter connected to a battery
supose the load conected to the inverter demand 20A ,and the battery are fully charged,where will the 10A go,?
how the charge controler know that the battery are fuly charged since the inverter demande current .
normaly since the charge controler see the battery charged , it will turn off ,and will not give the 20A to the load?

NB:
(the charge controler did not have a dc outpout terminal)

The 10A just wasted because it not been used. or it even not produced.
