The Samsung Inverter cost P11 000 more than the conventional unit repairs to the inverter unit so far P14 000. So in our view you pay considerably more for the inverter when you buy it it might or might not use less electricity but these savings are offset by high repair costs. Manufacturers are aware of these circuit board problems.
