Networking and Communication

5.2 Morningstar MeterBus

Morningstar’s proprietary MeterBus

protocol allows communication between compatible Morn-

ingstar products. Use a MeterBus

network to:

• display select net system data for multiple TriStar / TriStar MPPT / TriStar MPPT 600V

systems**

• communicate with a TriStar Meter 2 -600V, a TriStar Meter 2 or TriStar Remote Meter 2

• communicate with a Relay Driver or other compatible Morningstar accessories (see sec-

tion 2.5 for more details)

**A Morningstar MeterBus Hub (HUB-1) and a TriStar Meter 2 (TS-M-2), TriStar Remote Meter 2 (TS-RM-2) or a TriStar Meter 2

600V (TS-M-2-600V) are required (not included).

AMeterBusHub(model:HUB-1)isrequiredforMeterBusnetworkscontainingmultiple

TriStar MPPT 600V controllers. The ports on the hub are electrically isolated to prevent dam-

age in the event of broken grounds or voltage differences between controllers. Figure 5-1 below

shows an example MeterBus

network with two (2) TriStar MPPT 600V controllers and a TriStar

Remote Meter 2 (TS-RM-2).
