Frequently Asked Questions

What is the difference between PWM and MPPT controllers?

PWM (Pulse Width Modulation) controllers are cost-effective and suitable for small systems. MPPT (Maximum Power Point Tracking) controllers are more efficient (up to 30% more energy harvest) and ideal for larger or high-voltage solar arrays.

Do LDSOLAR controllers support lithium batteries?

Yes, most MPPT models (especially Tracer Dream S and iTracer series) support LiFePO4, NMC, and other lithium battery types with customizable charging profiles.

Can I monitor my controller remotely?

Yes, the iTracer Dream Series supports Bluetooth connectivity and a dedicated mobile app for real-time monitoring, data logging, and firmware updates.

What is the warranty period?

LDSOLAR offers a standard 2-year warranty on all solar charge controllers, with extended warranty options available for distributors.

Do you offer OEM/ODM services?

Yes, we provide full OEM and ODM support including custom branding, packaging, and product modifications based on client requirements.
