Liquid crystal display. For status monitoring and set-up. Load output. Overcharging of the battery can be prevented by connecting all loads to the load output. The load output disconnects the loads when the battery has been discharged to a preset 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 are adjustable. Day/night time setting of the load output. This option offers the possibility to set a specific ON time after sunset. Programmable battery charging algorithm Pre-programmed algorithms for AGM, GEL, liquid electrolyte or LiFePO4 batteries (only with built-in BMS). Two 5 V USB outputs. Maximum current (both outputs together): 2 A.
