Solar Charge Controllers, Water Heating Elements, Diversion Loads

Solar Charge Controllers  These regulate power from solar electric modules protecting batteries from overcharge and shortening life of battery and electric loads. Battery voltage is monitored and when proper voltage is reached the controller stops or reduces charging. Controllers also prevent nighttime discharge of batteries into solar modules. Don’t overload controllers. Allow for the extra amps solar modules produce with reflected light and cold temperatures.


Solar Boosting Controllers   Get 10-25% more power from your PV modules when modules are cold or batteries are low!

Solar Converters  MPPT Charge Controllers

Changes solar electric module’s extra voltage into more charging amps. Gain 10% to 25% more power especially in cold weather or when battery voltage is low. PWM, 3-stage charging with bulk, then absorption rate, then lower voltage float rate. Has current and voltage limited output, lightning protection, load disconnect, low voltage disconnect (LVD). On 20 amp and larger models, there is a versatile power relay driver that is on anytime battery is not full.
Dual Voltage 12/24 volt models can charge 12 or 24 volt batteries. Also, PV modules can be wired for 24 volt to charge 12 volt battery. This saves on wire size and cost especially on long wire runs. 
36 Volt and 48 Volt
are nice for golf carts, electric tractors and other electric vehicles.
Can be used as a
motor/pump controller on PV direct systems: protects motor from high voltage, increases power available to motor with maximum power point tracking, and the LVD can be used with remote switch to turn motor on and off.  15 amp Controller is mounted on flat heat sink which can mount inside standard NEMA box. Made in Canada. The shipping weights are higher than actual weights so the shipping cost will be more accurate.

OutBack   MPPT Solar Charge Controller   For 12,  24,  32,  36,  48,  54, 60  volt  Battery

PV Charge,  Diversion,   DC to DC Converter,  Meter                             Remote Temperature Sensor with 20’ cable RTS 1 lb $29

FM60 60 amp, 14 lbs $750    Special $690                 FM80 80 amp, 14 lbs $850    Special $790

The FM60 Maximum Power Point Tracking (MPPT) charge controller is rated at 60 amps of DC output from 12 to 48 vdc with PV open circuit voltage as high as 145 vdc. Setpoints are fully adjustable to allow use with virtually any battery type or charging profile. Can be used as diversion controller or as a DC to DC converter to charge 12 battery from 24 volt or higher battery system.
Use a higher voltage PV array with a lower voltage battery - such as charging a 12 or 24 vdc battery with a 48 vdc PV array. This reduces wire size and power loss from the PV array to the battery/inverter location. Includes a four line by 20 character backlight LCD display for setup and monitoring of the PV array and battery system. Use the OutBack Mate controller/monitor for a remote display. Connects with ethernet computer cable (RJ45 Modular Connector CAT 5 Cable 8 wire). One OutBack Mate can monitor eight FM60 controllers up to 300 feet away. The output current to the battery is limited to 60 amps continuous to prevent tripping of the over current protection. So if you want to have a 48 vdc nominal PV array charging a 12 vdc battery, the input current would be about 12 amps at 60 VDC with about 60 amps at 12 vdc output. The physical size of the FM60 is close to the size of a C40 and has knockouts in the same locations as a C40 to allow easy replacement and upgrading with existing systems. The front surface of the enclosure the heat sink and it includes a small cooling fan to improve operation at high ambient temperatures. 5 year warranty, FM60 is 14.5” H, 5.75” W, 5.75”D    FM80 is about 3" taller. Made in India

TriMetric Solar Charge Controller, 30 amp, 12v/24v
Use with or without TriMetric Meter

For 12 or 24 V battery systems using Liquid Electrolyte batteries or with lower maintenance AGM sealed or Gel Sealed batteries.

A precision, high efficiency PWM (pulse width modulated) Solar Array Battery Charge Controller. Designed to maximize the life of your batteries by allowing the flexibility to adjust solar charging closely according to the way your battery manufacturer has specified. High performance depends on being connected to a TM-2030 TriMetric Battery Monitor. Controller can operate without being connected to the Battery Monitor with reduced features.

The SC-2030 is a "PWM" (Pulse width modulated) type that is simpler and less costly than a "MPPT" (Maximum Power Point Tracking) type charger. It can be as efficient—provided it is used with panels properly matched to the batteries as described. With this charger you may be able to get more solar performance at the same cost by purchasing another solar panel instead of a more expensive MMPT solar charger.

Includes $12 Battery Temperature Sensor with 10' wire.

Use with PV Modules with 36 cells for 12 battery. For 24 volt battery, series connect two 36 cell PV Modules or use 72 cell Modules. Controller protects itself and will limit current to 30 amps even if PV Modules are producing more than 32 amps.

Not supplied is a Four-conductor telephone wire to connect charge controller to the battery monitor. It can be up to 100 ft. long. These are common and are normally available locally.

Diversion Loads

Water Heating Elements  12 - 48 volt

About 20% of the energy used in a home is for hot water.  Some of this can be supplied by a solar or woodstove heater. Excess electricity from a wind generator or PV modules can also be used for water heating. Use one or more of these elements as a diversion load with Flexcharger,  Xantrex C35, C40, C60 or TriStar 45, 60 controllers. They fit most standard water heaters with screw-in elements. An adapter is used for the square flange type element. 150 watt hours will raise 1 gallon of water about 60º. Elements extend about 7" beyond the 1" male pipe threads on 1.5" hex head.

The dual 12/24 element has two separate 12 volt,  29 amp, 0.48 Ohm elements. It can be wired for 29 amps or 58 amps at 14 volts or 29 amps at 28 volts.
D380 12/24 volt Dual 29 amp, 0.48 Ohms 3 lbs $140     
Limited  Special  $49 

The dual 24/48 volt element has two separate 24 volt, 22 amp, 1.24 Ohm elements. It can be wired for 22 or 44 amps at 28 volts or 22 amps at 56 volts. Order enough elements with a total current draw greater than your charging system’s maximum output, but no more than 75% maximum amp rating of controller.
