FAQ
1. 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.
2. 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.
3. 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.
4. 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.
5. If the bulk charge voltage is 14.7V, does the charging voltage is the same 14.7V or other lower voltage?
A: When the bulk charge voltage of battery is set to 14.7V, the MPPT controller charge voltage will also be control within the range of 14.7V. It will charged the battery in three stages through constant current charge mode CC → constant voltage charge mode CV → floating charge mode CF.
In CC mode, the charging voltage is equal to the battery voltage;
In CV mode, the charging voltage is equal to the bulk voltage set value of 14.7V;
In CF mode, the charging voltage is equal to the floating voltage set value, like 14.5V.
6. Could i charge my golf cart acid battery with your MPPT controller?
A: Yes, you can set the MPPT controller charge parameter according to the specific charging parameters of golf cart acid battery (such as the bulk voltage and floating voltage value).
7. After shut down and restarted MPPT controller, will the setting parameters keep retain or revert to default setting?
A: All of our MPPT charge controller have storage memory function, it will keep the original setting parameters after shut down and restart.
