Maximum Power Point Tracking charge contollers offer

some advantages over conventional charge controllers.

The most widely known advantage is an increase in useable power going into

your batteries from a photovoltaic array.

When a photovoltaic module is connected in a system which has a battery, the

battery acts as a limiter to the voltage output of the array.

This is one of the reasons you see two voltages listed on the back of your

solar panel.

One voltage is the open circuit voltage, this is the voltage output the panel will

produce under full sun when you connect a volt meter to it.

As soon as a battery(s) or load is introduced into the system the voltage drops

to the operating voltage or less.

An MPPT charge controller "fools" the panels into producing a higher voltage

by "eliminating" their view of the battery(s) in the system.

This allows more power to go into the battery(s), up to 30% in some instances.

A more important advantage of MPPT to many people is that it allows you to use

an array with a higher voltage output than the operating voltage of the battery

system.

For instance, if the array has to be placed a great distance away from the charge

controller and battery, the wire size must be very large to reduce the voltage drop.

With an MPPT controller, you can wire your array for 24 or 48 volts (depending on

the controller and your panels) and bring the power into a 12 or 24 volt battery

system.

This greatly reduces the wire size needed while retaining the full output of the

array.

With the cost of heavy gauge wire, this can be a significant savings.

One of the stand-alone systems at our location is comprised of four

Solarex Millenium 48 volt / 43 watt modules.

These are combined in parallel below the rack in a fused disconnect.

From there, the wire run to the back of the building is about 100 feet to

an outdoor disconnect.

Inside the disconnect is a Solar Converters mod. PT 48 - 8B 12/24

charge controller which steps the voltage down to 24 volts to feed

a 24 volt gel cell battery bank to supply a 24 volt true sine wave inverter

and 24 volt interior lighting.

The voltage drop on the long wiring run is minimal as the controller

allows the modules to operate at, or near their open circuit voltage of

103 volts d.c.

A few of our customers, due to trees or terrain, have wiring runs

of up to 300 feet.

When you can not mount the modules close to your batteries this

is the only way to set up a successful system.

Many people have gotten deals on photovoltaic

modules with odd output voltages.

Some of these panels were designed strictly for

a specific grid-tie application and many have

high wattage ratings.

This is most common in "24 volt" and "48 volt"

panels.

If your modules do not have a standard voltage

please call us at (562) 423 - 4879 or call

Solar Converters at (519) 824 - 5272, to have an

MPPT controller set up to your panel voltage at the

factory.

There is no extra cost for this but as they would not

ship from our standard inventory the lead time can

be one to two weeks.

If you are not sure, just call us.
