Product Details
Renogy Rego 12V/24V IP67 50A DC-to-DC Battery Charger with MPPT
The Renogy Rego IP67 50A DC-to-DC Dual-Input Battery Charger with MPPT delivers intelligent, efficient charging in a slim and durable design.
Its advanced boost-and-buck technology supports 12V and 24V input and output systems, allowing it to increase or decrease voltage according to the application. The charger intelligently combines alternator and solar input while prioritising available solar energy, helping reduce alternator demand and maximise auxiliary-battery charging.
With up to 720W output, an IP67-rated enclosure and advanced communication capabilities, it is ideal for caravans, motorhomes, campers, overlanding vehicles, marine applications and off-grid systems.

Intelligent Dual-Input Charging
The charger intelligently combines vehicle-alternator and solar power, automatically adjusting its charging behaviour according to available sunlight and driving conditions. Solar power is prioritised whenever available, helping reduce wasted energy and alternator operating time.
12V and 24V Compatibility
Advanced boost-and-buck technology allows the charger to operate across 12V and 24V systems. This provides flexible charging between compatible 12V and 24V alternator and auxiliary-battery configurations.
Energy Monitoring and Communication
Bluetooth energy monitoring provides convenient access to compatible system information, while wired CAN, Modbus and RV-C communication support integration into compatible vehicle and power-management systems.
