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 10-30% more power from your PV modules when modules are cold or batteries are low! |

MorningStar SunSaver
MPPT 15 amp 12 or 24
Volt Battery Charging.
The SunSaver MPPT (Maximum Power Point
Tracking) charge controller is designed for 12 and 24 VDC battery charging
from a PV array with a maximum open circuit voltage of 75 VDC. Use up to
three 36-cell PV modules in series or a single 60-cell or 72-cell module to
provide up to 200 W when charging a 12 VDC battery or up to 400 W when
charging a 24 VDC battery. Maximizes the output of the PV array by rapidly
finding the array’s peak power point with extremely fast sweeping of the
entire I-V curve, providing an estimated 5-25% power boost over PWM or
simple on-off controllers, especially during periods of colder temperatures
and low battery voltages when it is most needed. |
SSMPPT-15 3 lbs $383 |
|
Has a simple
DIP-switch setup for plug-and-play operation or is fully programmable for
custom and advanced programming with a PC connection using the PC
MeterBus Adapter (MSC) and Morningstar’s MSView software
(available for free on Morningstar’s website). Also compatible
with Morningstar’s MeterHub. The UMC-1 communications adapter
converts the Morningstar MeterBus RJ-11 electrical interface to a standard
USB 2.0 interface which allows communication between a Morningstar charge
controller or inverter and a PC computer. Programmable lighting control for up to four time periods and is adjustable with respect to hours/minutes after/before – Dusk/Dawn/Solar Midnight/Solar Noon. Mounts on DIN rail with DIN-1 rail clip. 6.6"H x 2.75"W x 2.2"D, 5-year warranty. |

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.

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. | |
