How much is 300 units?

About 1,165.39 baht including VAT on rate 1.2 at the rates from the September 2569 bill, roughly 112 baht less than at the old rates.

How do I know if I’m on rate 1.1 or 1.2?

It’s on your bill. A 5 A meter is rate 1.1 and moves to 1.2 after 3 months in a row over 150 units; a meter larger than 5 A is always 1.2.

A per-unit charge that follows fuel costs, reviewed by the ERC every 4 months. For September–December 2569 it is 16.23 satang per unit.

No. Home rates, service charges and Ft are the same; PEA just numbers the rates 1.1.1 and 1.1.2.
