Hello to everyone ! im totaly new in the forum , sorry about my english , im from greece
yesterday buyed a DC/AC inverter 12v --> 220v 600w
i've connected the 12v power from the battery directly , and i measured the ac currend and always was on 190-205volts , never 220.....
my car when is off the battery has 12,5v and where on 13,8v
i've connected my pc , after inverter and worked correctly ...... is possible that the measure (190-205v) was wrong ?
using the lights , starting engine and some extra power for tft and other stuff , the battery dc volts was going from 10v to 13.8v
my inverter cuts the power where the dc volts drops down 10.5v .... so my pc is rebooting ......many times my inverter beep and tells me that the dc power is not enough ....
what i have to do for better working ?
nevere rebooting .....or hanging my pc system ?
and regoulating the power......
What kind of backup battery i need to use , for not having drops in my 12v inverter input ?
because my inverter stops working when power dropes down 10,7volts
what kind of diode is needed ?
That diagram won't work very well as the car starter will suck the backup battery's current as well as the car's battery.
14" LCD, EPIA MII-10000, 256MB, Wireless LAN, GPS, CDRW/DVD, ELM Scan,
200wRMS inverter (for the screen), CarPC Pro v2.4 Power Controller,
2 12" Pioneer Premiers, Sony 6x9s, Sony Xplode Class D mono block, Pheonix Gold A/B amp for highs
i've put the diode in the wrong place
this is the correct diagram
I've build the circuit above
using an mbr3045 diode , but the problem didnt solved..
where my cars battery falls down to 10.4 , the backup battery dosent
give the apropriate 12v to the inverter ....
but the circuit works correctly , if i disconnect the car battery , an using only the backup , and visa versa
what's the problem?
