7.0 Frequently Asked Questions (FAQs)

Before a problem is suspected with the system, read this section. There

are numerous events that may appear as problems but are in fact

perfectly normal. Please visit gpelectric.com for the most up-to-date

FAQs.

It seems like my flooded batteries are losing water over time.

Flooded batteries may need to have distilled water added periodically to

replace fluid loss during charging. Excessive water loss during a short

period

of time indicates the possibility of overcharging or aging batteries.

When charging, my flooded batteries are emitting gas.

During charging, hydrogen gas is generated within the battery. The gas

bubbles stir the battery acid allowing it to receive a more full state of

charge. Ensure they are in a well-ventilated space.

My voltmeter shows a different reading than the GP-PWM-30 display

The meter value on the GP-PWM-30 display is an approximate reading

intended

for indication purposes only. There is an approximate 0.1 volt

inherent error present that may be accentuated when compared with

readings from another voltmeter.

There may be a slight difference between the battery voltage displayed

on the GP-PWM-30 display and the battery voltage measured at the

battery terminals. When troubleshooting using a voltmeter, check both

the battery voltage at the GP-PWM-30 controller terminals and battery

voltage at the battery terminals. If a di

fference of more than 0.5 volts is

noted, this indicates a large voltage drop possibly caused by loose

connections, long wire runs, small wire gauge, faulty wiring, a faulty

voltmeter or all the above. Consult the Suggested Minimum Wire Gauge

chart in Section 5 for wiring suggestions and check all connections.
