Why you need a solar controller

When you use a solar panel, and want to transfer the solar energy store to the battery or use it to charge your mobile, or lunch a lamp.

Then you may need a solar charge controller to transfer the energy , and protect the battery will not over charge to damage.

First, you many need to check the battery voltage, norV mally, the battery voltage is 12V/24V. this is the safe voltage for human. but now. the 36V 48V and 60V, even 72V battery , they with more efficient usage. and also , the battery voltage should math with the solar panel voltage.

This is the description of the 90W flexible solar panel.

And when you choose the solar panel, and the battery, you may need to pay attention to the description. to make sure their math with each other.

Solar Charge Controller 12V/24V 100A

MPPT Solar Charge Controller 12V/24V 100A you can also customize your logo on it


MPPT 48V 60A Solar Controller

This new model MPPT 48V 60A solar charge controller, why it is different ?

Normally, the most controller could compatible 12V and 24V battery, this MPPT solar charge controller could compatible 12V / 24V /36V /48V battery recognition automatically. also the battery type is from Gel to Flood and the Lead-Acid battery.
