Operation
5.0 Networking and Communication
5.1 Introduction
The TriStar MPPT 150V provides several communication options. The TriStar MPPT 150V uses
a proprietary protocol for the MeterBus
TM
network and the non-proprietary open standard MOD-
BUS
TM
and MODBUS TCP/IP
TM
protocols for RS-232, EIA-485, and ethernet networks. Addition-
ally, HTTP, SMTP, and SNMP are supported for web page, email, and network message support.
Morningstar’s MSView
TM
PC software provides system monitoring and logging capabilities via
RS-232, EIA-485, and ethernet. MSView
TM
PC software is available for free on our website at:
http://www.morningstarcorp.com.
Further, hardware and third party software that supports the MODBUS
TM
protocol can also be
used to communicate with a TriStar MPPT 150V.
Multiple communication ports can be used simultaneously. For example, a TriStar MPPT 150V
may be connected to a MeterBus
TM
network for on-site system metering, connected to the inter-
net for remote monitoring, and connected to an EIA-485 network to bridge data from other con-
trollers in the system to an internet connection. Note that the RS-232 and EIA-485 connections
share hardware and therefore cannot be used simultaneously.
Table 5-1 below provides a summary of supported features for each communication interface.

Schedule Maintenance Items
2 weeks after installation
Re-tighten power terminal connections to specified torque
values.
3 months after installation
Re-tighten power terminal connections to specified torque
values.
Monthly or After Each
Equalization
Inspect the battery bank. Look for cracked or
bulging cases, and corroded terminals.
For wet cell (ooded type) batteries, make sure the water level
is correct. Wet cell water levels should be checked monthly or
according to the manufacturer’s
recommendations.
Annually
Clean the heatsink fins with a clean, dry rag.
Inspect all wiring for damage or fraying.
Inspect for nesting insects.
Re-tighten all wiring terminal connections to specified torque
values.
Inspect the system earth grounding for all components. Verify all
grounding conductors are appropriately secured to earth ground.
