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
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.
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.
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.
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 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.
Operating characteristics for the NC12L12 (we stock the NC30L12):
The bottom line.
Why would you buy one of these instead of an import costing about 2/3's as
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 had 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
But just as important, around 2006 I put in a 12 volt 330 watt system at our old
Long Beach, CA location.
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
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 would power up the security lighting every night
when the sun went down and shut them off every morning.
We no longer stock this charge controller but can special order one for you.
