Question - Can Amptron LiFePO4 batteries charge from a standard commercial solar module or does it require a special module? And is there a need for a controller?
Response - The battery can be charged from standard commercial solar modules, but it definitely requires a solar charge controller. Now, when it comes to solar charge controllers, our batteries can be charged from most nominal 12V controllers however there are compromises. When it comes to modern solar controllers, there are 2 main characteristics that needs to be considered:
To sum all of this up, yes you can charge our Amptron batteries with standard commercial solar panels, but a charge controller will be needed. As for charge controllers, an MPPT charge controller will definitely be the preferred option unless lowering cost is really necessary, and as for MPPT charge controllers, it is preferable to use an MPPT charge controller that can charge the battery with an LiFePO4 profile.
