Configuration

GenStar MPPT
4.0
can be configured for a unique function:
1) Threshold - no scheduling
.
Choose whether the threshold will be reached from a rising (lower)
or a falling (higher) value, relative to the threshold; choose a variable, and then enter the desired
ON and OFF thresholds, along with desired delays. Activate ReadyRelays using Command buttons
(after configuration in LiveView Installer ReadyRelay setup assignment).
2) Faults/Alarms - no scheduling.
Activates a relay for optional devices when Block is
programmed for specifically occurring fault conditions:
A) When charging has stopped due to a fault
B) When charging has stopped due to high battery voltage
C) When Load has disconnected due to a fault
D) When the load has been disconnected due to high battery voltage
E) An over-temperature alarm has occurred
F) Charging current is being limited
3) Charge Stage - no scheduling
.
Toggles the relay for use with optional devices when the
selected charge period - Bulk, Absorption, Float, Equalization, Night - is active. Further, relay start
and exit delays can optionally be entered.
4) Custom (see Section 4.2.8, below) External Source Control (ESC) Start-Stop.
A)
Assign a relay
to, “ESC Start-Stop” signal.
B)
Go back to LiveView\Installer Setup\ESC, and program accordingly
for desired Timing Controls and custom ESC schedules. Also see Section 5.9.5 - ESC Commands.
5) Command/Schedule.
To allow a command to trigger a Manual - see Section 4.2.8, #2, below
- relay activation (Ready Blocks\Relay ON), assign relay as, “Command/Schedule”. Relays can
also be assigned for specific operation - see #s 1-4 above. In addition to toggling a relay On-Off as
a command, a Command/Schedule assignment also allows relay operation to be scheduled in the
Schedules menu.
NOTE:
Proper generator/auxiliary equipment relay wiring is required - see ReadyRelay
manual for terminal connections diagram.
4.2.8 External Source Control (ESC) -
Installer Setup
IMPORTANT:
To enable the use of the Manual or Automatic Source Control Profiles, a ReadyRelay
must be used to trigger ESC. At least one External Source Control (ESC) signal must be assigned to
a relay - as seen in Section 4.2.7 (above) nos. 4 and 5.
INTRODUCTION
External Source Control (ESC) is an Installer Setup feature that allows the user to program the
GenStar MPPT to run or turn off an external charging source in different ways. ESC, e.g., generator
input, is an important auxiliary energy source in many off-grid systems. The main LiveView screen
includes options to adjust external source controls, timing controls and External Source Control
Modes (ESCMs).
External Source Control Modes (ESCM) SETUP SCREENS:
The ESCM Drop-down has options for Disabled, Manual or Custom Profiles. Only one ESCM option
can be programmed at a time, and the ReadyRelay assingments will govern which mode can be
used.
1) DISABLED
- External Source Control function is disabled
Absorption End - Amps -
set a net current threshold below which the controller will transition from
the Absorption to the Float Stage - see Absorption End Amps Time below.
Absorption End - Amps, Time -
set the time required below Absorption End Amps threshold for the
controller to transition from the Absorption to the Float Stage.
4.2.6 Schedules
(Setup and Installer Setup)
Use the Schedules Page to define schedules for ReadyRelay function. The Ready Block Section,
below, describes various ReadyRelay functions. Note that only
External Source Control (ESC
) and
Command/Schedule
functions are schedulable, and require a relay assignment in Ready Block
configuration .
The Schedules Page sets only the Relay-ESC timing. Timing can also be set in ESC Schedules Page,
and both are updated when saved. To define ESC conditions, Custom Mode scheduling must be
used. The following schedules - in order of precedence - are available in Installer Setup\ESC:
1) Prohibit - no criteria/conditions, overrides all other schedules
2) Emergency - set criteria in External Source Control (ESC) schedules
3 Pause - defines the hours of the day during which charging can be paused. Define criteria that, if
true, will pause charging during these hours.
4) External Source Control (ESC) Start Charging 1, 2, 3
4.2.7 ReadyBlocks
TM
(Installer Setup)
ReadyRelay (RB-Relay-1)
The ReadyRelay is an expansion block that adds AC and DC-rated relay dry contact hardware
functionality and firmware control and logic to the Morningstar GenStar MPPT charge controller.
ReadyShunt (RB-Shunt-1)
The ReadyShunt is an expansion block designed measureand display net current flow into the
battery, or to measure and display source or load auxiliary current.
ReadyBMS (RB-BMS-1)
The ReadyBMS provides simple visibility of battery performance, hands-free settings and optimized
battery control. Through the ReadyBMS, the GenStar MPPT will report any data variable contained in
the battery BMS. The Block can also iterface with lithium batteries for, "closed loop", charging and
data reporting.
IMPORTANT:
To enable the use of the Manual or Automatic Source Control Profiles, at least one
External Source Control (ESC) Control signal must be assigned to a relay (block) -- see Section 4.2.8
on ESC.
Configure. I
nstalled blocks will populate the Ready Block Configuration Box in LiveView webpage.
The ReadyShunt can also be configured in the local display meter. The position of each block is
listed by positions 1-3, relay or shunt A or B. Position 1 is the left-most block. Relay A is on the left,
and relay B is on the right. Shunt A uses the upper-tier terminals, and Shunt B uses the lower-tier
terminals. Choose a block to configure.
