18 PV Solar charge controllers with night lighting load by Flexcharge
SES Flexcharge model NC30L12 solar / photovoltaic charge controller with night time
( dusk to dawn ) lighting and load control.

Made in the U.S.A.

For 12 or 24 volt systems.

This charge controller is designed for use in photovoltaic installations only.
It is user setable for either 12 or 24 volt systems and will power up loads, such as security
and area lighting, when the sun goes down.

It can power a load up to 12 amps and outputs either 12 or 24 volts d.c. depending on what
the operating voltage is of your battery bank.

Basic Operation:

This is a 30 amp solar charge controller which uses the same gentle method as the NC25 and NCHC
controllers.

When it sees the incoming photovoltaic voltage dropping below the battery voltage (at sunset),
it turns on your lighting or other loads.
When the incoming voltage rises above the battery voltage (at sunrise), it shuts off the loads and
starts charging your batteries.

It has a low voltage disconnect which shuts off the loads in the event that your battery voltage drops
too low.
This protects your batteries from damage.

We have been using one here for our security lighting since 2007.

For use with GEL, AGM, Lead acid and Ni-Cad flooded cell battery types.
We use ours with four Trojan T-105 batteries wired in series/parallel for a 12 volt system.
It requires a diode for operation of the night time feature - we include two diodes of your choice.

international rectifier 182nq030 schottky diode

    International Rectifier 182NQ030 Schottky diode.
    Rated 180 amps and up to 30 volts.
    It has a very low forward voltage loss, the voltage drop
    can be up to 0.41 volts passing through the diode.
    The input is on the top, you supply a standard 1/4"-20 bolt
    and washer and outputs through the base.







International Rectifier 2490150 schottky blocking diode

    International Rectifier 2490150 Schottky diode.
    Rated 240 amps and up to 150 volts.
    It has a very low forward voltage loss, the voltage drop can
    be up to 0.72 volts passing through the diode.
    The input is on the top, you supply a standard 1/4"-20 bolt
     and washer and outputs through the base.






NCL controller features:

Waterproof packaging - should not be used in direct sunlight.
Reverse polarity protected on battery output.
Very high efficiency.
Has a manual load test - low voltage disconnect reset by a magnetically
operated switch under the load status indicator. You can easily reset the lvd
circuit after installation and test the controllers load circuitry.
The Low Battery Disconnect is delayed to prevent disconnect when momentarily
high load currents occur.
The dawn sensing circuit is delayed to prevent the loads from being turned off
if the pv modules are exposed to vehicle headlights or flashes of lightning.

These can be special ordered with different options shown on Flexcharge's
website - we stock the standard model.

The bottom line.
Why would you buy one of these instead of an import costing about 2/3's as
much?
Many years ago we were selling a major name brand line of charge controllers
(we sold over a thousand of their different models.)
They started out building them in the U.S. (we still have one in one of our 12 volt
systems), then they went to Taiwan and then to China.
First off, we had to stop handling them because of the quality and customer
support.
But just as important, around 2006 I put in a 12 volt 330 watt system here.
It was for security lighting and to run some interior lighting and loads.
We installed one of their charge controllers with a night time feature - it lasted
about six months. I replaced it with another one and it lasted a little over six months.
These controllers were from different production runs.
I got fed up with throwing money down the drain and installed this model of Flexcharge
in 2007.
Not a hiccup in eight years.
There is a picture of it here in our educational website:


It looks nasty after all of these years but it will power up the security lighting tonight when
the sun goes down and shut them off tomorrow morning.
