Frequently Asked Questions

What types of batteries are compatible with this MPPT controller?

The controller supports a wide range of batteries including GEL, Sealed, Flooded, LiFePO4 (Lithium Iron Phosphate), Li(NiCoMn)O2, and user-defined custom settings.

What is the maximum PV input voltage?

Depending on the model, the maximum PV Open Circuit Voltage (VOC) ranges from <60V for smaller models up to <150V for high-capacity 48V models.

Does this controller support mobile monitoring?

Yes, it offers optional internal Bluetooth or external WIFI communication modules, allowing you to monitor and setup parameters via a mobile app.

What is the difference between natural cooling and fan cooling models?

The 20A to 40A models use an efficient natural cooling heatsink design for silent operation, while the higher power 50A to 100A models utilize intelligent fan cooling for optimal heat dissipation.

Can this controller activate a "dead" lithium battery?

Yes, this MPPT solar charge controller features a specialized Lithium Battery Activation function to restart lithium batteries that have entered sleep mode due to low voltage.

What protection features are built-in?

It includes PV and Battery Reverse Connection protection, Battery Over/Low Voltage protection, and Overload/Short-circuit protection to ensure long-term system safety.
