Solar Converters Inc - PPT 90-6
96V @ 6 Amps Linear Current Booster
Pump Driver

PPT 90-6

Application

Used to control and power a DC motor from a solar panel. The unit prevents stalling of the motor under less than full sun condition. The power of the sun is transformed to the motor running conditions so as the sun goes down the motor slows down instead of stalling. Conversely, or as the sun comes up the motor starts running much earlier instead of staying stalled for hours when it could be running. This translates into more running time of the motor where it spends a lot of time working instead of stalled doing no work.

Features

• Voltage Limited Output
• Greatly increases water flow, even under reduced sunlight conditions (over 40% likely)
• Transient Protected on the input and output
• Float Switch input for on/off control
• Ultra High Efficiency >94 %
• Weatherproof NEMA enclosure

** Special units have a suffix of M XX after the par number. The maximum output voltage of the pump driver is XX. For example PPT 90-6 M24 will power a 24 V motor from a nominal 96 V solar panel. Note that the motor current increase by the ratio of approx. 85/24. Thus a 1 amp 48 V nominal solar panel will power the 24 V motor at approx. 3.5 Amps.

Mechanical Specifications

• Weight: approx. 2 lb.
• Size:4.5" X 2.5" X 2" nominal, resembling a junction box with mounting feet
• Operating Temperature: -40 to 70 deg. C
• Humidity: N/A NEMA 4 enclosure

Connections

• Power: PV and Load

6 inch # 16 AWG flying leads

Input: Red = PV +, Black = PV -

Output: White = Pump +, Blue = Pump -

• Signal: float switch, 12/24 V select

6 inch # 24 flying leads yellow: connect to PV - = OFF for float switch operation

6 inch # 24 flying leads purple: connect to PV - = 24 V operation disconnected = 12 V operation

6 inch # 24 flying leads red / black: Output Current Sense scaled at 50 mv = 10 A

Application Notes

1. This Pump Power Tracker(TM) is quite capable of putting out over 15 amps into a stalled load even from a single 30 watt 4.5 amp panel. It is recommended that a fuse or overtemperature switch matched to your pump motor be incorporated in the system to protect your pump or motor.
2. Float switch operation draws microamps of current, i.e. small wire gauge, allowing long distance runs between float switches / holding tanks, and PV / pump driver without the need to string long lines of heavy gauge wire.
3. Unit is a true 6 amp unit, all necessary derating already accounted for.
4. As with all electronics, it is recommended the unit not be mounted in direct sunshine.
5. Solar panel or energy limited input only.
6. Output fuse required. Bussman KAB-10 is recommended.

Special Shipping Note:
All Solar Converter Products are behind in production. These items are usually shipped directly from the manufacturer in Canada. They cannot be shipped by any expedited methods such as UPS Blue or Red. They will generally be shipped via Canadian Express Mail which avoids import brokerage fees of $50-$60. Lead time on these products may be up to 4-6 weeks depending on their production. This is true of all Solar Converters products with the exception of the battery desulphator (item code SORBD-2) that we stock in our warehouse. If you want Solar Converters products to be shipped by normal Canadian Post, but would prefer to have the rest of your order to be shipped by a faster method, please write this information in your order's notes during checkout.
