Solar Charge Controllers
|
Solar charge controllers are used in battery based photovoltaic / solar
electric systems. Charge controllers protect the batteries from overcharge
and/or excessive discharge. The minimum function of the charge controllers
is to disconnect the solar electric array when the battery is fully
discharged and to keep the battery fully charged without damage.
The basic criteria for selecting a charge controller includes the operating
voltage and the PV or solar array current.
Charge controllers are critical components in stand-alone PV systems
because a controller failure can damage the batteries. The controller must
be sized to handle the maximum current produced by the PV array. There are
two types of charge controllers: Series and Shunt. Series
charge controllers stop the flow of current by opening the circuit between
the battery and the PV array. Shunt charge controllers divert
the PV array / solar array current from the
battery.
Both
types use solid state battery voltage measurement devices and shunt
controllers are 100% solid state.

The Outback Power MX60 Power
Charge Controller
The Outback Power MX60 solar charge controller allows the flexibility to
use
any solar panel configuration voltage,
up to 130vdc input, and step the voltage down to 12vdc, 24vdc, 36vdc, or
48vdc.
The Outback MX60 enables
you to design or expand your photovoltaic array by providing previously
unknown wiring options. Use any manufacturer's solar panel for your system
just wire up to 130 volts input. Never before has photovoltaics
been so flexible.
·
The MX60 saves time on installation
·
Dramatically extends the distance your array
can be from the battery bank
·
Reduces cable size and cable costs
·
Increase your solar electric power output up
to 25%
·
Daily data logging
·
(MPPT) Maximum Power Point Tracking
priced at $549.00

Morningstar - Sunsaver solar charge controller
|
|
|
The
SunSaver battery charging design closely copies
the ProStar advanced charging algorithm: The series
PWM algorithm is very stable, yet responds instantly to changing
conditions. Maximum charging efficiency is ensured, with minimum stress on
the battery. The constant voltage PWM charging is a proven advancement
compared to the common on/off PV regulators.
