SRNE MPPT 50A DC-DC Charger/Regulator

The SRNE MPPT 50A Charge Controller (MD1250N05) is an advanced device that enables efficient energy management in power systems based on solar panels and alternators. Thanks to PowerCatcher MPPT technology, the controller achieves exceptionally high Maximum Power Point Tracking (MPPT) efficiency—up to 99.9%—ensuring optimal use of solar energy in harsh weather conditions and variable sunlight. The device supports both photovoltaic (PV) panels and alternators, allowing simultaneous charging of two batteries—auxiliary and starter. It's an ideal solution for campers, yachts, or off-grid systems requiring reliable and efficient power supply. Additionally, the controller is fanless, making it completely silent, which is important in applications where noise is undesirable, such as recreational vehicles, boats, or homes.
The built-in LCD display allows for real-time system monitoring, and the optional Bluetooth module enables remote control of parameters without the need for an internet connection. PowerCatcher MPPT technology ensures faster response and higher maximum power point tracking efficiency, resulting in a tracking efficiency of up to 99.9%, highly effective in changing sunlight conditions.
The SRNE MPPT 50A controller supports various battery types, including gel, sealed, open, and lithium. It also supports temperature compensation for lead-acid batteries, which contributes to a longer battery life. The device is compatible with a wide voltage range and allows charging of both auxiliary and starter batteries from photovoltaic panels and generators.

The controller also provides comprehensive hardware and software protection, protecting the system from damage. The multiphase Buck-Boost rectifier provides DC/DC conversion efficiency of up to 98%, enabling optimal charging efficiency.
With monitoring and parameter configuration features via mobile apps and PC software, users can customize charging settings to their needs. The controller also supports remote control, allowing for convenient control without requiring physical access to the device.
