design features 80V Buck-Boost Lead-Acid and Lithium Battery Charging
Controller Actively Finds True Maximum Power Point in
SolarВ Power Applications
Tage Bjorklund In solar power systems, the
bulk of the expense is in the
panel and batteries. Any
cost-effective solar power
solution maximizes the
capacity usage and lifetime
of these components.
For instance, a high
quality charger increases
battery run time, reducing
capacity requirements, and
extends battery lifetime,
minimizing maintenance
and replacement costs.
Likewise, using a DC/DC
controller that extracts the
maximum available energy
from the solar panel
reduces the size and cost
of the panels required. The LT8490 is a charge controller for lead …
