On Tuesday September 7 Coulumb asked "What battery voltage and current do you measure just before it trips to float?" As we have only just got back into wireless range I couldn't access the internet when I did this test and forgot that it was the voltage reading requested. I will try to rember this when next testing and advise the reading. However, it appears as though the system goes from Absorption to float when the batteries get past 81% full, 3/4 Full or 637 AH Remaining.

You should read the Emon manual section labelled 'Accuracy and Usability'. The manual is online at: http://www.amplepower.com/wire/emon_2001/index.html.

You should also re-read the short article on this forum at:
http://www.amplepower.com/phpBB3/viewtopic.php?f=3&t=36

These will help you make better use of the Emon.

Thanks Coulomb,

I've printed out both documents and will endeavour to understand them when I read them. Unfortunately, I'm not a Techie.

During the week I will ask a specialist DC workshop to provide help.

Cheers,

Peter

I ALSO HAVE AN ERRATIC READ OUT. HAVE TRIED SHUTTING POWER DOWN AND IT WORKS FOR A WHILE THEN QUICKLY BACK TO ERRATIC
LAST TIME DIDN'T WORK. ANYTHING ELSE I CAN TRY?
SERIAL# EMONIHI-10058. VERY FRUSTRATING!
THANKS C.KINGDOM

This may be caused by a memory failure of some sorts. Powering off for a few seconds clears up arithmetic accumulators.

Do you have abnormal settings in battery efficiency?

we are plugged in at the moment and batteries are up good.
when unplugged we have a solar system (eight panels on roof) that keeps the batteries up to the top.
