Hi, Larry, and welcome.

I suspect you will have a number of questions from folks considering the lithium option.

Thanks for joining the forum.

Hi Larry,

Would you recommend a MPPT charge controller over a PMW for your LiFeBlue lithium ion batteries? I find it odd that Zamp doesnt use MPPT's on there installs.

   Thanks for your help.

Hello Mike,

A MPPT controller should be used with any PV solar modules (aka solar panel, a misnomer) that has a Vmp (the operating voltage) of 17.0V or higher. It does not matter what kind of battery you have. 

A PWM controller is like a switch: it turns on and off and will only pass the rated current of your module. This causes you to loose potential power which I’ll explain later. A MPPT controller can capture all the power that a module can produce by using DC converters. 

Consider this example: 100W PV module rated at 20 Vmp and 5 Imp (the output current). According to Ohms law, Volts x Amps = Watts. So, for our above module, here's the math: 20V x 5A = 100W. Also know that a solar module is a constant current device. In our example, you will get about 5 Amps from 0 to 20 volts. 

A PWM controller will directly connect the PV module to the battery. A battery is a load and will pull down the voltage of the module. If the battery is 13 volts, here's the math: 13V X 5A = 65W. You only produce 65 Watts of power because the amperage is at 5A and the voltage is pulled down to 13V. 

If you use MPPT controller with the same module, you can produce nearly 100 Watts of power. The difference is that the MPPT controller converts the 20 Vmp down to 13V and raises the current at the same time. By this conversion process, you can raise current because the power (100W) is still available. You now get about 7.5 Amps from your 100W solar module. Here’s the math: 13 x 7.5 = 100W (you loose some in the conversion process)

There are other factors affecting performance but using MPPT for high voltage modules is important. Hope this helps!

I guess I don't know the difference between "PWM" and  "MPPT" controllers.  Maybe I don't need to know?

Sorry, I'm a business major 😏

Larry,

Glad to know you.  My wife and I have ordered an Ollie and are considering going with the lithium pro package.  Please send me the specification sheet for the LifeBlue batteries that are used in this package.  Also, provide information on LifeBlue the company and how long you have been selling this particular battery.

Sincerely,

George Gonzalez

Susan - 

Larry explains the difference between these two types of controllers above.

Hello George,

Here's a link to the data sheet on the LiFeBlue Battery website: http://www.lifebluebattery.com/ewExternalFiles/LB12200-HCLT Data Sheet.pdf

The low temperature battery was introduced about 1-1/2 years ago. It is the same as our standard 200AH except it has the heater circuit. The latest version, and the one that OTT uses, is model LB12200D-LT. This version has an RS-485 data port built in for programming and future use. We have been selling our batteries for about 4 years now.

Our OEM is Shenzhen Topband Battery Co. and they design and manufacturer our cells and custom BMS. Topband has developed Li-ion batteries for over 13 years. They have worked with us to consistently improve our battery features and quality. You can learn more about our manufacturer in the attached video.
