 The
Solar Boost 2000E provides a precision Multi-stage Pulse
Width Modulation (PWM) charge control system to ensure
the battery is properly and fully charged, resulting
in enhanced battery performance with less battery maintenance.
An equalization function is also included to periodically
condition liquid electrolyte lead-acid batteries.
A built-in LCD digital display monitors solar charge
performance. The display shows battery voltage, solar
panel current and output charge current. You can actually
see current boost working by noting the difference between
solar panel current and output charge current. A charge
status LED indicates the present charge mode, and shows
when the battery has become fully charged. |

How do Solar Boost controllers increase charge
current? |
Solar Boost controllers increase charge
current by operating the PV module in a manner that
allows the module to produce all the power it is capable
of under present operating conditions. A conventional
charge controller simply connects the module to the
battery when the battery is discharged. When a 75W module
in this example is connected directly to a battery charging
at 12 volts its power production is artificially limited
to about 53 watts. This wastes 22 watts or nearly 30%
of the available power.
Patented MPPT technology used in Solar Boost controllers
operates in a very different fashion. The Solar Boost
controller continually calculates the module's maximum
power voltage, in this case 17 volts. It then operates
the module at its maximum power voltage to extract maximum
power available. The higher power extracted from the
module is then provided to the battery in the form of
increased charge current. In conditions where extra
PV power is not available (such as in high ambient temperature
areas), Solar Boost controllers will operate as a conventional
controller with very low voltage drop.
The actual charge current increase you will see varies
primarily with module temperature and battery voltage.
In comfortable temperatures, current increase typically
varies between 10% to 25%, with 30% achieved with a
discharged battery and cooler temperatures. |
