The SRNE Eco System Complete Solution brings solar charging, alternator charging, mains battery charging and intelligent electrical monitoring together in one integrated system. Designed for campervans, motorhomes, caravans and off-grid installations, it combines the SRNE SAA 3-in-1 Battery Charger, CU2 Control Unit, RMA7 7-inch Touchscreen and BS48500 500A Battery Monitor.
At the heart of the charging system is the SRNE SAA 1250, which combines three essential charging functions in a single unit. It manages power from solar panels through its integrated MPPT controller, charges the leisure battery from the vehicle's electrical system using DC-DC charging, and provides mains battery charging when connected to a suitable AC supply.
The CU2 Control Unit connects compatible SRNE equipment into a centralised management system, with built-in Bluetooth and WiFi connectivity for monitoring and control through the SRNE mobile app. The RMA7 colour touchscreen provides a convenient onboard interface for viewing battery condition, charging activity and connected equipment.
Battery monitoring is handled by the BS48500 500A Smart Battery Monitor, which measures current entering and leaving the leisure battery to calculate its remaining state of charge. This gives users a clearer understanding of available battery capacity and energy consumption while travelling or camping off-grid.
The system can also be expanded with compatible water tank level sensors, temperature sensors and additional SRNE electrical equipment, making it a flexible foundation for a modern campervan or motorhome installation.

Installation Information
The SRNE Eco System Complete Solution is designed to integrate the vehicle's solar panels, alternator charging supply and mains electricity into a coordinated leisure battery charging system.
The SAA 1250 manages the three charging sources, while the CU2 communicates with compatible equipment and the RMA7 touchscreen. The BS48500 is installed in the battery negative circuit to measure charging and discharging current.
All equipment must be installed using correctly sized cables, suitable fuses and appropriate circuit protection, following the manufacturer's wiring instructions.

Frequently Asked Questions
The SRNE Eco System Complete Solution combines four main components: the SAA 1250 3-in-1 Battery Charger, CU2 Control Unit, RMA7 7-inch Touchscreen Display and BS48500 500A Battery Monitor. Together, they provide solar, alternator and mains leisure battery charging with centralised electrical monitoring and control.
Yes. The SRNE SAA 1250 3-in-1 charger supports three charging sources: solar panels through an MPPT controller, the vehicle's 12V electrical system through DC-DC charging, and a suitable AC mains supply. This reduces the need to install separate charging devices for each power source.
Yes. The system supports compatible LiFePO4 lithium leisure batteries as well as suitable lead-acid batteries. Charging settings must be configured according to the battery manufacturer's specifications to ensure safe and effective operation.
Yes. The SRNE CU2 features built-in WiFi and Bluetooth connectivity, allowing compatible electrical system information to be accessed through the SRNE mobile app. With a suitable internet connection and correct configuration, supported remote monitoring and control functions can be accessed when away from the vehicle.
The SRNE RMA7 touchscreen provides a central interface for monitoring the leisure battery and compatible connected SRNE equipment. Depending on the devices installed, users can view battery state of charge, charging information and system performance, as well as operate supported electrical controls.
Yes. The kit includes the SRNE BS48500 500A Smart Battery Monitor, which measures current entering and leaving the leisure battery. It calculates battery state of charge and provides information about electrical consumption and charging activity through the connected monitoring system.
Yes. The CU2 supports compatible water level and temperature sensors and incorporates six 6A relay outputs for controlling suitable electrical equipment. This allows the system to be expanded to monitor fresh water and waste water tanks and operate supported lighting, fans and other low-current accessories.
No. The standard kit contains the charging and monitoring components but does not include a 230V inverter, leisure battery or solar panels. Compatible equipment can be added separately to create a complete campervan or motorhome electrical installation.
