hi all ,,,,,
system of ( 4x panels 12v, each 200w connected to PWM charge controller feeding 3x batteries 12v ,each 200amh connected in parallel then going to an modified inverter 2kw )
that is the system of power.
on out put of inverter connected a load of 300w . after 3 days by sudden I got an electric shock when I touch one terminal of a battery ,
when I touch the other end also the same,,, I felt like there is 220v ( but how can happen coming back from inverter to batteries ).
I brought a tester screw driver that work on 220v normally , and when I put it in any of batteries terminal it shows that there is a high voltage . cuz the light in tester wont ( light up ) with voltage much less than 220v .
i brought a voltmeter when i connect 1 end of the voltmeter in ( + ) of battery and the other end on ground ( i mean the floor where i am standing ) the meter read 35v ,
when i connect 1 end of the voltmeter in ( - ) of battery and the other end on ground ( i mean the floor where i am standing ) the meter read 49v.
anyway i split the system that connected to output of inverter and checked it 1 by 1 ,,,
i found i have this problem only in the cable ( i mean the cable only connected to inverter alone no load at end and no touch between L and N cable ),
and when i use a new cable connected to load every thing is ok ( i mean there is no problem from load ).
until here every 1 will say the problem is in cable and that is obvious ,
BUT .... why it happened ? and the cables are brand new and of good quality and they can handle the load .
