AH both up and down is just as useful, maybe more, to me that a SOC reading the is just a calc off of the AH reading.

The big deal to me is if the counter resets based on getting a confirmed...

The thing to remember with any of the low cost, simple, monitor/counters is to be sure that there is a way to calibrate them after charging but before discharging, preferably automatically during...

You are pretty close on your thoughts on the size of the solar. If the panel could do 10 amps continuous and the batteries had a 100% charge efficiency, it would take 10 hours to recover 100ah. ...

I don't think that will necessarily fix anything because many/most solar controllers don't really know if the batteries are full when they go to float because they use voltage, time, or an algorithm...

I assume we are talking about AGM batteries at those voltages??


If so, it is highly likely they were not anywhere near full from the charging. It can take upwards of 10 hours of absorption time...

Absolutely true and especially the derating. More than 1/3 may even be needed if you put it in a box or in a hot area with poor ventilation.

What settings does that two way meter allow you to do? That will normally give a pretty good idea how they are doing the reset calibration.


IMO, Peukert is a non issue and more or less a bogus...

I hadn't gone down far enough for the full description. oops


That said it would be interesting to see the manual to see what they say about how the calibration is done. If it just resets when...

Re the meter in the link. Does it do the automatic reset to zero at recharge like the Magnum and Victron do? I have found that many of the units that are in the that range of price are strictly...

The direct to 13.5v if the charger thinks the battery is full is common, but not all chargers do that, especially solar controllers so you have to read the literature to find out if yours works that...

There are lots of threads with the proper charging of AGMs on this forum, but in generally the absorption stage is commonly speced by the manufacturers somwhere between 14.3 and 14.7v so I doubt the...

I am not sure what it will do if you swap the two wires as the interruption might shut it down or reset it somehow. Most likely it will continue counting from where it was so if you charged 80ah and...

Be aware that unit you ordered is a one way only, so you can either read charging or discharging, but not both. To do both ways you would need two of them. They also do not auto reset to calibrate...

With all battery monitors you need to tap into the negative battery cable and also connect the wires from a shunt if used to the unit display if used.

Voltage is not a very reliable method of knowing battery state of charge as it is influenced by too many things. Battery type, model and brand, battery age, is it in a "rested" state, are there any...
