Can I use BT139-800 or BT139-800E ?
I am a beginner in electronics and trying to fix 875VA & 675VA inverter boards.

Both inverters have problem in charging section. one inverter is taking high current from battery while inverter is on and then battery low indicates then inverter goes off and another inverter is taking high current while charging battery. but both inverters are making noise.
somehow found that triac may be the faulty one.
also need to identify the value of the those variable preset.
Please check the zip file for inverter PCB.
