Why Choose This MPPT Solar Controller?
- MPPT Tracking Efficiency >99%: Continuously finds the optimal operating point of your solar panels, delivering significantly more energy into your battery compared to PWM controllers.
- High Conversion Efficiency (≤98%): Minimal heat loss means more of the sun's energy ends up stored in your battery bank.
- Auto 12V/24V Detection: Automatically identifies your system voltage — no manual configuration needed.
- WiFi Connectivity & App Control: Monitor and adjust charging parameters remotely from your smartphone via a free companion app (iOS & Android).
- Clear LCD Display: Real-time readout of voltage, current, power, and battery status for at-a-glance system monitoring.
- Dual USB Output (5V/3A): Charge phones, tablets, and other USB devices directly from your solar system.
- Large-Section Wiring Terminals: Wide-pitch, heavy-gauge terminal blocks improve insulation reliability and reduce voltage drop in the wiring circuit.
- Wide Application Range: Ideal for solar street lights, residential rooftop systems, solar billboards, RVs, camper vans, solar awnings, and off-grid cabins.
- Temperature Compensation: Built-in coefficient (-2mV/℃/2V) automatically adjusts charging voltage based on ambient temperature for optimal battery health.
- IP21 Protection Rating: Provides protection against solid objects and dripping water in covered installations.

Frequently Asked Questions
Q: What is the difference between an MPPT solar charge controller and a PWM controller?
A: An MPPT (Maximum Power Point Tracking) solar charge controller continuously adjusts its input to harvest the maximum available power from your solar panels, then converts it efficiently to charge your battery at the correct voltage. This typically results in 20–30% more energy harvested compared to a PWM (Pulse Width Modulation) controller, especially when the panel voltage is significantly higher than the battery voltage.
Q: Does this MPPT controller work with lithium (LiFePO4) batteries?
A: This controller supports common battery types including sealed lead-acid, gel, and flooded batteries. If you intend to use it with lithium batteries, please verify the charging voltage parameters are compatible with your specific battery pack's requirements before connecting, as lithium chemistries have strict voltage limits.
Q: What solar panel size do I need for the 30A model on a 12V system?
A: For the 30A model on a 12V system, the maximum supported PV input power is 360W. You can use one or more panels wired in series or parallel as long as the total wattage stays at or below 360W and the open-circuit voltage (VOC) does not exceed 100V.
Q: Can I monitor and control this controller remotely using my smartphone?
A: Yes. This controller features built-in WiFi connectivity. After downloading the companion app and pairing the device to your home or site WiFi network, you can monitor real-time charging data, battery status, and adjust settings from your smartphone — iOS or Android — from anywhere with internet access.
Q: Is this controller suitable for use in an RV or camper van solar setup?
A: Absolutely. This MPPT controller is well-suited for mobile solar applications including RVs, camper vans, and solar awnings. Its compact size (130 × 130 × 58 mm), auto 12V/24V detection, and built-in dual USB ports for device charging make it a practical and versatile choice for on-the-road solar power systems.
