4.4 LED Indications

KEY:
G = green G - Y - R = flashing sequencially
Y = yellow G / Y
R = red G / Y - R = G and Y flashing together,
alternating with R flash

4.4.1. Power-up

Normal power-up: Status LED flashes G, then SOC LEDS
flash G - Y - R, then SOC LEDs indicate battery charge status
with a single battery status LED.
Failed bootload: Status LED flashes G, then SOC LEDS
flash G - Y and stop on solid Y.

4.4.2 Status LED

The Status LED indicates charging status and any exist-
ing solar input error conditions. The Status LED is on when
charging during the day and off at night. The Status LED will
flash red whenever an error condition(s) exists. Table 4.4 lists
the Status LED indications.

NOTES:
1) R flashing is generally a user addressable fault / error
2) R charging status LED ON with heartbeat blink OFF
every 5 secs is a critical fault that generally requires service.
See, "Solid Charging Status LED with Self-test (R-Y-G) SOC
Faults", in Section 5.1.

4.5 Alarms

Solar Overload
No LED indication. The EcoBoost MPPT will limit battery
current to the 20, 30 or 40 amp maximum rating. An over-
sized solar array will not operate at peak power. The solar
array should be less than the EcoBoost MPPT nominal max.
input power rating for optimal performance. See Section
7.0 - Technical Specifications for more information.
