Smart MPPT Solar Controller 30A 40A 50A 60A for RV, Boat, Home
Solar Power SystemsHigh-performance MPPT solar charge controller designed for off-grid
solar systems in homes, cabins, RVs, boats, and telecom sites.
Supports multi-voltage battery systems and offers comprehensive
protections for long-term, reliable operation. 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.

FAQDoes 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. - ✔ 99% MPPT Tracking
