46. view 1 2 Specifications The ISMG solar inverter is designed in order to be connected up to 3 independent PV generator and it could run automatically without any kind of preliminary configuration When one of the DC input supplied by a string of modules 15 higher that the minimum MPP voltage value 100Vdc and it is lower than the threshood value of PTV 130Vdc the device start up and run in the Control System Mode if the voltage value is lower than 130Vdc the inverter is in the Monitor Mode and it supply no energy to the grid If the DC input voltage get over the PTV value and all the conditions of the system are under control the inverter run in the Power Supply Mode so it supply energy to the public grid If the DC input run under the min value of MPP voltage 100Vdc the solar inverter automatically switches it off The device will switch it on automatically when the input voltage increase over the upper minimun MPP voltage Congratulations on the purchase of this technically high quality solar inverter These directions will help you become familiar with this product Please read it with maximum accuracy Please consider the safety regulations EN61000 4 2 and technical connection conditions for local utility company Careful handling with your product will contribute to its service life durability and reliability These are essential prerequisites for maximum yield Please consider the following notes on safety During operation of e
