why battery voltage drop much at bigining ?

[littleharbor]

Bogart Tri Metric is a shunt based meter that will give you an approximate SOC%. It needs to be programmed with battery amp hour capacity. It counts amps into and out of your battery. If you are heavily discharging your battery your amp hours capacity will be less than if your very lightly discharging which will cost you some accuracy.. Bear in mind it is only as accurate as it's programing. As your battery ages and loses capacity it will lose accuracy unless the Ah. setting is updated. If your need for state of charge isn't mission critical this meter can be helpful.

thanks a lot suneagle for your time and information

thanks a lot littleharbor for your time and your information surly was helpful cuz when I enter the metric name in amazon I saw many types and got more information , although still as you and suneagle said the battery need to be charged and discharged at the same time .

( then the only way is the charge controller screen since the battery already in recharging mode ). I was just needed to compare with the charger.
thanks again for all.

suneagle , is your meter uni-t ut202 can measure the current by using the clamp ? cuz it isn't mentioned in the tool information.
as it is mentioned in uni-t ut210

I think my Uni T is an older model then the ut210. It does have a clamp on as well as the ability to measure AC & DC voltage.

Here is a picture of me using it on my small system.

when I wrote your model number in amazon I saw it with aclamp ( like the red 1 on the floor ) not the orange 1 with cables .

The orange one is just an Extech multimeter. The Uni is the red one on the right. Maybe I am confused with the model number. It is stored in my shed right now and I am going by memory.

According to Google, it looks like they are now calling the meter a UNI T UT202A which is probably an upgraded version of what I purchased.

Scratch what I just said. I have the UT203 meter not the 202. Sorry for the confusion.

Yes that one looks nearly identical to mine. A bit more costly, I think the 202 will not do clamp on DC.

Yeah the 202 is only an AC amp meter. I got the model number wrong and I need to apologize to zolar if I sent him on a wild goose chase.

thanks a lot suneagle and bcroe for explaination,
and yes suneagle the modle now is 202A and as I said in modle details not written to read sc amps by clamps that's why I will go for 210 cuz as I saw it can raed dc amps using clamp , and btw brother no need for apologize , ( master never apologize to trainee ) , its more than enough for me that you reply and confirm the right information

may I have any advice please which 1 is better : Uni-T B4Q094 UT210E

Signstek UNI-T UT210E

UNI-T UT210D

all of same price , but really need this advice ,thanks in advance

It looks like the UT210E is newer then the D model but IMO it is a toss up as to which to get and how much you want to pay for the meter.

thanks a lot suneagle , got another question please but , I don't know if you will understand me ,,,, I have 2 regulators ( lets say regulator1 , and regulator2 now I got output wattage from regulator1 (-, +) I need to connect them to my battery bank , and an output wattage from regulator2 (-,+) , also I need to connect them to my battery bank. the question is ( is it right , to connect both + from both regulators going to + of battery ,,, and both -- from both regulators going to -- of battery ) or the voltage will be doubles and its not correct?
SO THE QUESTION IS : CAN I CONNECT POWER FROM TWO REGULATORS OR MORE TO SAME BATTERY BANK?

[Mike90250]

I'm going to take a stab at this - Generally, it's safe to connect several properly adjusted charging sources to a single battery bank.

[zolar]

thanks a lot mike , ( so the amount of amps will increase but the voltage wont be increase ) right ?
but what you mean PROPERLY ADJUSTED , if you connect each 4 panels to 1 charge controller and you have output from 3 charge controllers , all 3 (+) terminals will go to battery (+) and the same for (-) , so where is the unproper could be?
