Lithium Wake-Up; Current Derating - Dometic Go Power! GP-SB-PWM-10 User Manual

10. LITHIUM WAKE-UP

When the GP-SB-PWM is powered by a PV panel but the battery is not detected, it sends 5 pulses to restore a Lithium battery
that has been protected from over discharge by its BMS. The LCD indicates this process by showing the displays below.
If a battery is still not detected after the fifth trial, the controller shows error number 32 to ndicate this failure. The controller gives
up until it is either manually reset by disconnecting and reconnecting solar power, or the back button is manually pressed to
restart the process, or the controller detects a new day.

11. CURRENT DERATING

The GP-SB-PWM constantly monitors the temperature of the PCB power train to ensure it does not exceed UL limits. In applica-
tions that require full output current in high ambient temperatures, the solar controller starts limiting the current delivered to the
battery to keep the PCB temperature within UL specifications.
