and interrupts current as required by the U.S. National
Electrical Code.
Wire Box for ProStar MPPT
A modular wiring box that can be added to any version of
ProStar MPPT controller. The box acts as a junction (using
knock-outs) to run controller wiring to external conduit, if
desired. The wire box cannot be used with rigid conduit.
The communications accessories / adaptors below should
be housed in the Wire Box for ProStar MPPT.
Communications Support:
Ethernet Communications Adapter (EMC-1)
This product is an Ethernet gateway that provides web
monitoring services, a Modbus TCP/IP server, and a local web
page server. End users can collect information about their off-
grid PV system remotely. One EMC-1 supports all products
with MeterBus ports by bridging MODBUS TCP/IP requests
to serve LiveView pages for each product.
USB Communications Adapter (UMC-1)
A modular unit that uses a USB-B plug, usually from a USB
A-B computer cable, and an RJ-11 plug to connect with a
Morningstar controller's MeterBus port, for monitoring and
programming using MSView PC software.
PC MeterBus Adapter
TM
(Model: MSC)
The MSC converts the MeterBus RJ-11 electrical
interface to an isolated standard RS-232 interface which
enables communication between the ProStar MPPT and a
personal computer (PC). The MSC is required for program-
ming custom charging set-points, and for logging data. See
Section 4.7 for information on programming.
