All,The utility(Flathead Electric Co-op) has recently completed automatic meter reading using a power line carrier for all co-op members. I will give them a call to find out the type and frequency of signaling. The state 104 has been occurring within 10 minutes of connecting to the grid. Perhaps
Hi Fellow Wrenches,
Thanks for the insight that AMR systems could interfere with not
only data monitoring (previous thread) but also with the inverter
control function, too.
I have attempted to gain some insight into the AMR system the
Kent,I just talked with Mike in the meter department. The utility does indeed use Aclara TWACs AMR. The meter reading signal can vary but is usually done at midnight or it could be set to every 8 hours, 1 hour, etc. However, a time sync signal is sent every 15 minutes. This correlates with the

You apparently misunderstood my poorly worded question I am sorry, I meant...
why can't they make a big 1110 AH 2 volt... like Surrette does.
I have seen very few truly defective cells in the 45 years I have been in the
battery business. Its true cell failure is a common enough

Hi John,
A related battery question.
Some equipment folks send a stick on battery temp sensor vs the bolt on type.
Do you recommend removing the cover and attaching the TS to the actual battery
or just sticking it to the top of the red case?
And if we can remove the top what do we re-glue it
Jeff,
The TWACs signal is a nasty beast. It is low frequency and thus very
hard to filter. It seems to cause problems with a large variety of devices.
Unless someone has taken the time to check, how do they know if the
other inverters aren't offline for 5 of every 15 minutes?
I think the
