any desired point on the meter map. A lit key indicates
a valid direction in the map. The current location is
indicated on the display with a column heading, and a bold
descriptor.

4.6.2.2 Adjusting the Meter Display

The display setting options, as shown in Figure 4-2, are
adjustable by using the directional keys to locate and edit a
desired setting or variable.

4.7 Data Logging (future use)

The EcoBoost MPPT logs thirty days of basic system data:
• Daily minimum battery voltage
• Daily maximum battery voltage
• Daily Events (Equalize triggered, Entered Float, Alarm/
Fault occurred, Reset)
• Faults / Alarms - recorded only if a fault or alarm occurs
that day
• Daily charge to battery
The EcoBoost MPPT USB Micro-B port (for future use) will
allow data transfer in mobile applications.

4.8 Auxilliary USB Charging

NOTE: When using USB-A charging cables, install the
included ferrite choke(s) by wrapping at least one
loop of cable through the core in a position as close to the
EcoBoost MPPT as possible. Chokes will ensure compliance with
electromagnetic emissions standards.
1) The EcoBoost MPPT has two USB-A ports for use as
charging sources for small electronics. Energy is taken
from the system battery, so any auxilliary charging must be
balanced with other load draws on the system battery.

Operation
2) The USB charging ports will operate in all conditions
except for LVD, HVD, or a user requested Load Disconnect
(from a meter command, for example). In LVD, HVD & Load
Disconnect, the main load and the USB ports are powered
off.
3) If the main load gets faulted for some reason (shorted
FET, etc), the USB charging ports will still operate.

4.9 Inspection and Maintenance

Table 4-6 below lists the recommended maintenance
schedule to keep your EcoBoost MPPT performing
optimally.
WARNING: RISK OF ELECTRICAL SHOCK.
NO POWER OR ACCESSORY TERMINALS ARE ELEC-
TRICALLY ISOLATED FROM DC INPUT, AND MAY BE ENER-
GIZED WITH HAZARDOUS SOLAR VOLTAGE. UNDER CERTAIN
FAULT CONDITIONS, BATTERY COULD BECOME OVER-
CHARGED. TEST BETWEEN ALL TERMINALS AND GROUND
BEFORE TOUCHING.
WARNING: SHOCK HAZARD
DISCONNECT ALL POWER SOURCES TO THE
CONTROLLER BEFORE REMOVING THE WIRING BOX
COVER. NEVER REMOVE THE COVER WHEN VOLTAGE
EXISTS ON THE ECOBOOST MPPT POWER CONNECTIONS.
