MPPT 60AMP Solar Charge Controller 12V 24V 36V 48V DC Battery Regulator Testing results on 12 volts

[sam_sam_sam]

I bought one recently but this is the first weekend that I did not have work Saturday morning or the sun did not want to cooperate with me but today it is coordinating with me and I run a very simple test on a 12 volt battery pack and it stop charging ar 14.4 volts

Here is the website link where I bought it from

I ran this test with a new 12 volt solar panel that has a no load voltage of 19.0 and an output current of 9.1 amps

I do not remember the starting voltage but the charging amps was 1.4 amps

I do not use computer for making an inventory list of parts but this might helpful at some points but because I only have a few places to get parts I remember what there name are and there location where to find them but I really just use part number and look them up for me it simpler

I will usually keep circuit boards that are not completely burned if they have a lot of components on them or I have more than one device that has the same boards but a different set of algorithms or parameters because you can still use the other components I also do this because I want to see if it...

Unfortunately unless you build the device you are not going to know exactly how it will respond in the real world testing because I have found in my endeavors the true value of a device is not known until you test the hell out of it

This also true for proof of concept projects as well...

This device you do not have a subscription you just have to buy the device

The reason I am after a DVR that I can record with is sometimes I am at work when the program starts or it finishes before I get home and over the internet streaming services do not allow you start from the beginning again or watch it when you have time

How I know this is when I have no cable tv service because the system in my neighborhood has issues I have had use cable tv streaming services which is okay but not perfect unfortunately

There are only a few programs that fall into...

Lately I have been having cable tv box issues that seem to be resolved for the moment but I am getting tired of system upgrades that are increasingly taking longer to make them to work correctly and paying a premium amount of money for this service unacceptable the aggregation for the last month

Here is a link for one

As you are aware of I have issues with the tariffs and all of these games that they want to play
And It makes making decisions very difficult to make now because I do not want the extra cost...

[sam_sam_sam]

Is this a cable tester or is it something more than that

If it is something else please explain what you are going to use it for and explain what you are testing for...

This would depend on what your main reason for buying another one for if it just for comparison purposes or are you after accuracy or is price a concern then this is another or at these are determining factor for me...

[sam_sam_sam]

I want to being with there products are very good quality I have one of there meters but not this model the accuracy of the seem to be decent it reads very close to my Fluke meter and most times it reads the same when I get home I will post the model number

I also have two current clamp meters as well

I would have NOT have any issue buying any of there products because I have several different products from them

I hope this helps you make your decision about buying any of there products

I normally am not brand loyalty because I find most times...

You need to preheat the board around the device that you want to remove and then use the hot air gun
If you have a toaster oven set the temperature 300*F or lower all that you are interested in is preheating the board so the heat does not escape to the rest of the board but used an infrared thermometer to measure the temperature do not go by the oven temperature settings because most of the time they are not accurate

Now you might want to remove the compartment that might be damaged by heat first

Or use two hot air guns one on top of the board and one on the bottom...

Not a real big problem to charge lithium ion battery packs it would probably only charge it up 90 to 95%

“Usage:

2.Connect it to the 24v battery, the inverter will works,
3.Connect it to the Mains and 24v battery at the same time, the inverter will works,and the inverter will charge your battery,the max charge current is 10A,the charge voltage is 28.8V. and the inverter will not stop working if the Mains no power suddenly.”...

I have my doubts about what it’s actual output really is
I have not read the reviews yet but I will definitely look at them and decide if this the rabbit hole I want to go down...

[sam_sam_sam]

There is something not quite right about the circuit and being hooked to lithium ion battery because there should be a sensing wire should be between the two battery cells or this nothing but a voltage monitoring ic chip have you looked up the ic chip that it connects to the battery cells

I agree with STJ in post number 12 about how he thinks this device works...

I just seen this item is this a good idea if why and if not why not

Here is the website link to it

It does but you have to google for it when you buy it comes with very tiny booklet and very hard to read...
