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 …
