Key Advantages
- Advanced MPPT with 99% Tracking Efficiency - intelligently extracts up to 30% more energy than PWM and auto-optimizes under sunny/cloudy conditions.
- Wide Battery & System Compatibility - works with 12V/24V/36V/48V systems; supports sealed/GEL/flooded lead-acid and LiFePO4 (optional); PV input up to 100V DC for series panels.
- Smart Battery Management - 4-stage charging (bulk/absorption/float/equalization) helps extend battery life by up to 200% with temperature compensation (-20°C ~ 60°C).
- Military-Grade Protection - triple reverse-polarity (PV/battery/load), 4000V lightning surge, and over-current/short-circuit/overheat with auto-recovery.
- User-Friendly Operation - 3.2″ LCD real-time data (PV V / charge A / battery temp), dual USB 5V/3A, optional Bluetooth/WiFi app monitoring.

System Compatibility & Sizing Tips
- Ensure PV Voc (at lowest ambient temperature) does not exceed 100V DC.
- Match controller current rating (30A/40A/50A/60A) to array current with ~15-25% headroom.
- Confirm battery type profile (lead-acid/LiFePO4) in settings before first charge.
What's Included
- MPPT Solar Charge Controller (selected current rating)
- Temperature sensor & user manual
- Optional: Bluetooth/WiFi module
Frequently Asked Questions
Does it work with lithium batteries?
Yes. It supports lithium profiles; LiFePO4 is recommended. Configure the correct voltage and protection values before charging.
Can I connect panels in series?
Yes, provided the total open-circuit voltage (Voc) stays below 100V DC at the coldest expected temperature.
Is remote monitoring available?
Yes. Add the optional Bluetooth/WiFi module to monitor and log data in the mobile app.
