093 years manufacturer warranty on all IVT products More products and information under www ivt hirschau com Clear LCD display with graphic symbols By means of the explicit graphic symbols the easy to read and clearly structured LCD display informs the user comprehensively about the current operation status of the system Extensive protective functions for safe operation Via microprocessor all relevant protective function such as overcharging deep discharge protection and overheating protection are controlled fully automatic Protection against overcharging As soon as the cut off voltage is reached the charging current is shut off by the solar controller Thus overcharging and damage to the solar battery is prevented Protection against deep discharge with automatic load shut off and reconnection The solar controller s deep discharge protection causes an automatic shut off of the load output in the case the battery voltage drops below the minimum voltage With this the deep discharging of the battery is prevented As soon as the battery is recharged and the battery voltage rises above the reset voltage the solar controller automatically reconnects the load output Protection against overheating The MPPTplus Solar Controllers are protected against overheating A built in temperature sensor assures that the solar controller shuts off automatically in the case of excessive heating 85 C As soon as the controller has cooled down it turns back on automatically Protection against short circuit and reverse polarity The controllers are protected against short circuit as well as against reverse polarity with the aid of a 10 A 20 A or 30 A flat fuse depending on the model Non return valve All IVT solar controllers are standardly fitted with a non return valve In the case of too low solar power for example at dusk or at night the non return valve prevents the discharging of the battery via solar module i 1 No solar voltage available device in standby mode 2 Sufficient solar voltage 3 Battery status indicator 4 Used system voltage 5 Load output status indicator on off 6 Overvoltage on the battery input Symbol explanation 1 2 4 5 63
