Atonic Charge Controllers
The Atonic line is a feature-packed PWM charge controller. It uses
a special algorithm to determine battery state-of-charge (SOC). SOC
is displayed and is the basis of all control functions. The Atonic
automatically adjusts charging to the battery’s age and degree of
sulfation. And when the batteries are discharged deeply, the Atonic
automatically equalizes. Temperature compensated and reverse polarity
protected. The LVD disconnects loads at 30% SOC and reconnects at
50%. Can also be used for dusk to dawn lighting control. Atonic controllers
automatically adjust to 12 and 24 volt systems. M models include LCD
volt and bar-graph amp meter. Dimensions: 7.25" x 4" x 2". UL recognized
for “M” units. 2 year warranty. |

Powermax
10 Amp Charge Control
This solid state charge control can be used to regulate 12 volt PV
systems with array current up to 10 amps. Low frequency pulse width
modulation prevents radio interference. An LED lights when charging
and flashes when the battery reaches regulating voltage. Charge voltage
is user-settable from 13.8 to 16.5 volts so it can be used with sealed
batteries, flooded batteries and alkaline batteries. Dimensions: 3.75"
x 2.25" x 1.5". 1 year warranty. |

Concepts ASC Charge Controls
The ASC is a solid state regulator that is encapsulated in epoxy.
It is ideal for 12 volt photovoltaic systems with one to five solar
modules, especially for outdoor and marine use, since it is protected
from moisture or sea spray. Low-frequency switching prevents radio
interference. A red light indicates charging and flashes when battery
is near full. “A” models include temperature compensation to vary
the full charge voltage as battery temperature changes. Order this
feature if batteries are installed in hot or cold locations. “E” models
have LVD. Dimensions: 4.7" x 2.55" x 1.5". UL listed and FM approved.
5 year warranty. |

Outback
MX60
The Outback MX60 Maximum Power Point Tracking (MPPT) charge controller
enables your PV system to achieve its highest possible performance.
The MPPT feature can give you up to 30% more power from your PV
Panels!
Rated for up to 60 amps of DC output current, the OutBack MX60
can be used with battery systems from 12 to 60 vdc with a PV open
circuit voltage as high as 140 voc. The MX60's setpoints are fully
adjustable to allow use with virtually any battery type, chemistry,
and charging profile.
The OutBack MX60 allows you to use a higher output voltage PV array
with a lower battery voltage - such as charging a 24 vdc battery
with a 48 vdc PV array. This reduces wire size and power loss from
the PV array to the battery location while maximizing the performance
of your system and saving you money!
The OutBack MX60 comes standard with an easy to use and understand
display. The four line, 80 character, backlit LCD display is used
for programming and monitoring of the system's operation including
built-in Data Logging with 64 days of memory.

Blue
Sky Solar Boost
The Blue Sky Solar Boost feature full reverse polarity protection,
selectable charge voltage for flooded and gel lead-acid batteries,
PWM charging and digital meter displaying battery voltage, PV array
current and output charge current. Output current limiting eliminates
worry about overload or nuisance fuse blow when PV output is unexpectedly
high. An equalize function is also included to periodically condition
liquid electrolyte lead-acid batteries. Can be used on any DC source,
even hydro or wind generators. An optional user friendly digital display
is available to monitor PV charge performance. The display shows battery
voltage, solar current, charge current, charge mode and state of charge.
It can be provided in the controller, as a remote panel installed
up to 300' away, or both. Optional temperature compensation of charge
voltage is also available to further improve charge control and battery
performance. Selectable compensation curves support lead-acid and
NiCd batteries. Mounts flush or with the wall mount box. 3 year limited
warranty. |

• Diversion Regulators & Loads
Water
Heating Element
Use one or more of these heating elements with an Enermaxer to turn
your excess power into hot water. They fit most standard electric
water heaters with screw-in elements. We have one model for 12 and
24 volt systems and another for higher power 24 and 48 volt systems.
The 12/24 volt element can be wired to consume 25 or 50 amps at 14.5
Volts or 25 amps at 29 volts. The 24/48 volt element can be wired
to consume 30 or 60 amps at 29 volts or 30 amps at 58 volts. Order
one or more elements with a total current draw greater than your charging
system’s maximum output, but no more than the maximum power of the
Enermaxer. If your water heater tank is designed for square flange
elements, use one square flange adapter for each element. |

Heating elements are mounted in an aluminum box with a fan to disperse
the heat. Order one or more heaters with a total max amps equal to
the maximum current available from all charging sources. The terminal
block accepts up to 1/0 wire. Do not exceed the amperage rating of
your diversion regulator. The 30 amp and 60 amp loads may be used
with the Enermax and the Trace C-60. The 30 amp loads may be used
with the Trace C-35 or C-40 and the voltage controlled switch. 2 year
