Inverters






Terminals SM2-MU: A, B, 4GND, Z, Y, or DC+ a DC - are used according to the inverter manufacturer.





If there is SM at the beginning of H-bus, sliding switches must be in ON position.

The same for the inverter - if it supports bus termination, the last one should be switched on according to the manufacturer's instructions. Description of inverter connection to the Solar Monitor unit and whether it supports the bus is to be found in the following table.
If there is manual address scheme in your inverters, you need to set up addresses, ideally beginning with address 1. E.g. 21: 1, 2, 3, …, 31. Procedure is described in inverter's manual. Usually set up with DIP switches or in LCD inverter menu.
