5.2 Morningstar MeterBus
TM
Morningstar’s proprietary MeterBus TM protocol allows communication between compatible
Morningstar products. Use a MeterBus
TM
network to:
• display net system data for multiple TriStar / TriStar MPPT 150V systems**
• communicate with a TriStar Digital 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 either a TriStar Digital Meter 2 (TS-M-2) or TriStar Remote Meter 2 (TS-RM-2) are
required, not included.
A MeterBus Hub (model: HUB-1) is required for MeterBus networks containing multiple
TriStar MPPT 150V 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) TriStar MPPT 150V controllers and a TriStar
Remote Meter 2 (TS-RM2).
