Compact Dual-Input MPPT Charger
This compact charger combines high-efficiency MPPT solar tracking with alternator charging to keep 12V battery systems reliable whether you’re parked, driving, or off-grid. It balances solar and alternator inputs, adapts to changing light and load conditions, and provides monitoring and protection to extend battery life and reduce hassle.
Benefits
- Harvest more solar energy and charge faster, so batteries spend less time low and more time ready.
- Reliable charging on the road or at camp — works with traditional and smart alternators to keep systems topped up while driving.
- Stable performance in partial shade or variable light, reducing the need to reposition panels frequently.
- Clear, real-time monitoring and configuration via app or wired interface simplifies setup and troubleshooting.
- Built-in protections and temperature tolerance give peace of mind and reduce the risk of battery damage or downtime.
- Compact, lightweight design fits tight spaces in RVs, vans, and small off-grid installations.
Features
- Advanced PowerCatcher MPPT algorithm with >99% tracking efficiency for maximum solar harvest.
- Stable MPPT performance in shaded or rapidly changing light conditions.
- Up to 20% more energy capture compared with PWM controllers under typical conditions.
- High conversion efficiency — up to 96% to minimize energy loss during charging.
- Buck MPPT topology for solar input and buck/boost regulation for alternator input.
- Dual-input charging: accepts solar and alternator sources simultaneously or independently.
- Compatible with 12V/24V alternators, including smart alternators (automotive alternators supported).
- Flexible charging modes: 3-stage (Bulk / Boost / Float) for lead-acid and 2-stage for lithium with BMS.
- Selectable charging priority between solar and alternator inputs to match your usage pattern.
- Comprehensive safety: over-temperature, overcharge, overcurrent, and reverse polarity protection.
- Multiple communications: Bluetooth, TTL, RS485, and CAN (RV-C) for monitoring and integration.
- Real-time monitoring and configuration available via mobile app or wired interfaces.
