However my unit is 2 years old and new ones may have different firmware (just guessing).

I am extremely happy with the monitor! It counts (5 sampling readings per second) AH going out from the batteries or going in into the batteries. At the middle of a sunny afternoon it shows 100% (=280 AH in my case). Then, when the sun goes down it stars to decrease and at 8 am it shows about 75% (which agrees with the consumption of the freezer). Then the sun and the solar panels increase the energy in the batteries again. In days of no sun (very rare here :-) ) I switch on the engine to charge the batteries!

I hope you get yours working as mine!

Regards, Vladis
Thank you vladis for your immediate reply. It seems that mine should be configured at fl - 03 now it's reading 0.00 when the inverter is OFF. I'll monitor if there are any changes. I hope i finally solved my problem. Many thanks vladis!

Re: Low Cost Battery Monitor

Hello again vladis, finally got mine to work... Sort of...

The meter is now monitoring both charging and discharging values but i seem to be losing .5 amps compared to my calibrated multimeter. When the sun goes down and no longer charging, the meter shows it discharging .5 amps until my charge controller no longer reads anything from the panel. Is this normal? Should i accept that this is all the meter can do?

I apologize for asking all this questions to you but i've tried everything and other opinions such as yours are invaluable.

Thank you.
