I had problems . . . and the process ended taking about 16 hours of “sparky” time . .split across 3 different days onsite. During this entire time, my cloud account was stuck in “commission has started” phase.
The first issue we ran into was the CT meter. I ended up ordering a new one . . but after reconnecting it a few times, we moved past that problem. I now own an “extra” Givenergy CT meter . . .
The next roadblock was the battery firmware. It took several tries to get that updated. Requires removing an internal USB stick, loading the new firmware onto a different USB stick, upgrading it, getting it back online with the original USB stick . . .
Then the final holdup was the battery drain/recalibration. That took 8+ hours.
All of this took multiple calls into GivEnergy support - my sparky and I took turns on hold . . .
In the end, it did all work . . but we burned many hours to get there.
It’s usually an EM115 meter or GivEnergy’s variant of it (GEM).
That’s what monitors the import/export, voltage, frequency etc via the grid ct clamp. Plus believe it maintains the totals e.g. total import, total export etc.
