Key features and benefits Large LCD display provides a comprehensive view of system status: charge current, discharge current, cumulative power generation, discharge power, and temperature. Includes light control with a programmable delay for convenient operation. Realtime monitoring of essential parameters: temperature, charging current, and discharge current are shown clearly for quick assessment and safer battery management. Builtin protection suite to safeguard the system: short circuit protection, open circuit protection, reverse connection protection, and overload protection help prevent damage and downtime. Reverse current protection with low heat generation and a selfrecovery function. This feature helps prevent damage to the controller without requiring manual intervention. Reliable and straightforward to use: the combination of a clear display and robust protections supports safer, more efficient operation of battery and energy systems. Specifications and performance highlights Display: large screen LCD with multiple data readouts for charge/discharge currents, cumulative generation, discharge power, and temperature. Protection: short circuit, open circuit, reverse connection, and overload protections are built in. Reverse current handling: protects the controller with selfrecovery capability and low heat generation. 23 practical use scenarios Home or offgrid solar systems: monitor charging and discharging currents, track energy generation over time, and manage lighting with a delay control to reduce standby consumption. Battery backup installations: realtime temperature and current readings allow proactive monitoring and safer operation for essential devices during outages. Portable or mobile power setups (camping, caravans, small trailers): compact data display and protective features help you manage energy use and prevent equipment damage in variable environments.
