Q1. It seems like my ooded batteries are losing water over time.
A. Flooded batteries may need to have distilled water added periodically to replace uid loss during charging. Excessive water loss
during a short period of time indicates the possibility of overcharging or aging batteries.
Q2. When charging, my ooded batteries are emitting gas.
A. 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 batteries are in a well-ventilated space.

Note
The Solar Controller will not charge if the battery is below 6V. The total rated Maximum Power Current (Imp)
of the PV input should not exceed 10A. The GP-PWM-10 will limit PV current above 10A. Although the controller will
accept PV current greater than 10A for a short duration, damage may occur if the controller operates continuously with
greater than 10A PV input.
