t12: When solar charger is providing current of larger than 3A, the voltage level of
level will decrease gradually due to standby power dissipation. When the
batteries are consumed to around 75% of their capacity (battery voltage
around 26.5V) the CPU will restart the charger. The CPU will use charging
current of 3A as a guide point. When the provided charging current is under
3A, the AC charger will be turned ON (e.g. Night time or cloudy day). As for
load, voltage of battery bank will increase gradually until 28.5V is reached
then the CPU will be shut off the charger to prevent overcharging. At this
decrease to the range of 26.5~28.5V (floating voltage level). If utility were to
