This is one of the worst company when it comes to delivery time and service. I have booked a Solar inverter and been waiting from past 10 days....... initially they tell within 2-3 days and then within 1 week but still no one cares. As a customer we have to call more than 10 times and know the update and they never call you what so ever and make you wait day after day...... Please think before purchasing anything from Silicon Controls
