 (3) 18-22AWG communications cables
It is recommended that industrial-grade shielded RS-485 cable be used in lieu of unshielded twisted pair. RS-485
communication cables are connected via the 5-pin connector to the port labeled (2) in Figure 3-39.When creating
a network of multiple inverters, the cables are terminated to the same 5-pin connector and 3-pin connector.
Figure 3-40 shows a single inverter communication connection in (1) and a network configuration in (2).
Shielded Cable: Solar PV inverters create an electrically noisy environment that can disrupt inverter
communication. It is important to use shielded cable to ensure communication is not interrupted.
Separate Communication Conductors from Power Conductors: Never run communication conductors in the
same conduit as power conductors. It is important to keep communication conductors away from power
conductors to reduce noise. If power conductors must intersect with communication conductors, it is
preferable to have the intersection at a 90 degree angle.
Monitoring Compatibility
The SOLECTRIA PVI 25TL-208, PVI 50TL-480, and PVI 60TL-480 is compatible with SolrenView and third-party Data
Acquisition Systems (DAS). When using SolrenView monitoring the Ethernet Network Card is necessary. If
connecting with third party monitoring providers, RS-485 connections must be used.
Connecting Multiple Inverters
Multiple inverters shall be connected together in a serial (daisy-chain) fashion only. It is also suggested to follow
the below requirements:
The maximum number of inverters in any single daisy chain is 32 inverters.
