FAQ


1. Where can I review the products parameter and manual before purchasing?

A: Related files can be found through through official website - Download.


2. Can you provide OEM or ODM service for customers?

A: Yes. Customers should provide formal Letter of Authorization. We will keep our partnership strictly confidential and customized products will be not sold to any third party.


3. Can MPPT charge controller charge lithium battery? How to set it?

A: Yes. All series controllers can set up “User-defined” battery type for lithium battery by APP or PC software. Galaxy, Master, Mars series can be reset battery type on controller itself, too.


4. How to set up the parameter to charge lithium battery?

A:At present, the MPPT controller charging is mainly designed for the traditional conventional battery pack (12V is composed of serial and parallel series), and the battery system is automatically identified according to the battery voltage. Therefore, if the lithium battery pack needs to be charged, it needs to be converted into a conventional battery. Group, the conversion method is as follows:

The nominal voltage of the lithium battery pack is between 9~15V, just like the 12V conventional battery pack, the internal

calculation ratio is=1;

The nominal voltage of the lithium battery pack is between 18~30V, just like the 24V conventional battery pack, the internal

calculation ratio is 2;

The nominal voltage of the lithium battery pack is between 32~40V, just like the 36V conventional battery pack, the internal

calculation ratio is 3;

The nominal voltage of the lithium battery pack is between 42~60V, just like the 48V conventional battery pack, the internal

calculation ratio is 4;

The nominal voltage of the lithium battery pack is between 72 and 120V, just like the 96V conventional battery pack, the internal

calculation ratio is 8;

The nominal voltage of the lithium battery pack is between 144~240V, just like the 192V conventional battery pack, the internal

calculation ratio is 16;

At the same time, there are two main parameters for battery charging, one is the main charging voltage value and the other is the

floating charging voltage value; so please check the main charging voltage value of the lithium battery pack first, and the

lithium battery pack has no floating charging pressure value, so it is recommended Set the float voltage value ≤ main charge

voltage value -- (0~0.3V)

For example, the parameters of a user's lithium battery pack are as follows: the nominal voltage is 48.1V (consisting of 13 3.7V

cells in series), and the maximum charge cut-off voltage is 54.6V (4.2V*13) (this parameter refers to Main charging voltage),

The steps for setting the MPPT controller parameters for the lithium battery pack are:

1). Calculate the conventional battery pack corresponding to the lithium battery pack, and the internal calculation ratio; 48.1V

is between 42~60V, just like the 48V conventional battery pack, the internal calculation ratio is 4;

2). Set the battery type to Custom Type User defined

3). Set the main charging voltage value = 13.65V (54.6V/4=13.65V; internal calculation magnification = 4)

4). Set the float voltage value between 13.33 and 13.65; (the main charge voltage is 13.65V-(0~0.3V)

The above settings can be made by the host computer, WiFi module, or controller (requires the model that can be set)


5. Is there a setting on the controller to tell it whether the batteries are sealed lead-acid or gel?

A: Yes, all of our MPPT charge controller can be checked and set up the conventional battery types (Sealed/Gel/Flooded) by LCD screen, APP and even PC software.
