Charging Curve
Bulk:
This is the first charging stage where the battery at low charge stage, typically 10%, receives the majority of its
charge. During this stage the battery brought to about 95% of its charger getting 100% of the available solar power.
Pulse (Maintenance):
At the end of bulk stage, typically when the battery reach 14.4 Volts, a maintenance mode
starts where the battery voltage can float between an high and low value fixed by the controller. These values are
temperature compensated in order to keep the battery at 100% charge stage in any condition.
