New Digital Meter

[UWEB]

This morning PEA came to my House to replace my old Meter with a Digital one. Had a bit small talk with the Supervisor and he told, that they work off a List of Houses where they know Solar is installed all over Prachuap Khiri Khan as first step. Once done they will continue to change the old Meters with Digital once. So be prepared for a PEA Visit .

A good reason, not to register your solar installation with them

Makes no difference, they know who has Solar. I'm registered but Neighbor not, but both we got a new Meter.

I should imagine it’s more efficient to replace all the meters together in a local area, especially if they’re on the same pole

you need a license/permission to export to the grid
it can be dangerous to export to grid when not supposed to

Dangerous?

In what way?

It is important to understand the difference between exporting to a live grid (no hazard) and back-feeding a dead grid (hazard to linemen).

 

All domestic-level grid-tie inverters implement anti-islanding which will kill the inverter should the grid go down.

 

I'm not aware of any instances where a correctly installed grid-tie inverter has caused a hazard to linemen.

 

There are documented instances of inverters that are not intended to grid-tie and domestic generators being incorrectly wired to back-feed and worker deaths have been reported.

 

It is vital to use the correct type of inverter and connect in the approved manner.

Only dangerous if you use equipment without anti-islanding provisions.

 

My inverter is on the PEA approved list, many are.
