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 (flooded type)
batteries, make sure the
water level is correct. Wet
cell water levels should be
checked monthly or accord-
ing 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.

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
A MEANS OF DISCONNECTING ALL POWER SUPPLY
POLES MUST BE PROVIDED. THESE DISCONNECTS
MUST BE INCORPORATED IN THE FIXED WIRING. OPEN
ALL POWER SOURCE DISCONNECTS BEFORE REMOVING
CONTROLLER WIRING COVER, OR ACCESSING WIRING.
5.1 LED Fault Indications
Load Over-current
Error Status LED: Flashing red. Battery status LEDs: R/Y-
G sequencing. If the load current exceeds the maximum
load current rating, the EcoBoost MPPT will disconnect the
load. The greater the overload the faster the load will be
disconnected. A small overload could take a few minutes to
disconnect. The EcoBoost MPPT will attempt to reconnect
the load two (2) times. Each attempt is approximately 10
seconds apart. If the overload remains after two (2)
attempts, the load will remain disconnected until power is
removed and re-applied.
Solar Short Circuit
Charging Status LED: OFF. Solar input power wires are
short-circuited. Charging automatically resumes when the
short is cleared.
Battery Reverse Polarity
No LED indication, the unit is not powered. No damage to
the controller will result. Correct the miswire to resume
normal operation.
