Networking and Communication
5.2 Morningstar MeterBus
TM
Morningstar’s proprietary MeterBus
TM
protocol allows communication between compatible Morn-
ingstar products. Use a MeterBus
TM
network to:
•
display select net system data for multiple TriStar / TriStar MPPT / TS-MPPT-600V-TR
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
TS-MPPT-600V-TR 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
TM
network with two (2) TS-MPPT-600V-TR controllers and a TriStar
Remote Meter 2 (TS-RM-2).

Up to five (5) controllers can be networked together with a single hub. Multiple hubs can be
daisy-chained together to allow networks of up to (15) controllers and (2) meters.

networking.
