Liquid crystal screen for status monitoring and setup. Load output prevents battery overloading by connecting all loads to the load output. The load output disconnects the loads if the battery is discharged to a specified voltage value. Some loads, especially inverters, are best connected directly to the battery. The inverter remote control is best connected to the load output. A special interface cable may be required; please refer to the manual. The voltage values for connecting and disconnecting can be set. Day/night time setting of the load output allows you to set a certain time after sunset. Programmable battery charging algorithm includes pre-programmed algorithms for AGM, GEL, liquid electrolyte, or LiFePO4 batteries (only with integrated BMS). Two 5 V USB outputs with a maximum current of 2 A (both outputs together).
