8.7 Errors

Over Voltage

If the GP-PWM-30-UL

experiences a battery over

voltage (>15.5 VDC) on

battery bank 1, the controller

will stop operating, and the

display will begin to flash with

all icons. The controller will

resume operating when the

voltage drops to a normal level

<15.5 VDC.

Icons Displayed: All symbols

The controller does not display over voltage on battery 2.

Low Voltage

Low battery 1: If the SOC of

battery bank 1 reaches 0%,

the battery SOC symbol will

show the text “LOW” beneath

it. The controller will continue

operating in this condition and

will only stop operating if the

voltage of Battery 1 drops

below 9.0 VDC.

Low battery 2: If there are

two battery banks connected

and the SOC of battery bank 2

reaches 0%, the battery SOC

symbol will show the text

“LOW” beneath it. The

controller will continue

operating in this condition and

will only stop operating if the

voltage of Battery 1 drops

below 9.0 VDC (this is

because the GP-PWM-30-UL

is powered by Battery 1).

Icons Displayed: Battery SOC Symbol, LOW, Symbol 1 or 2
