Solar Converters Tc2 Battery Temperature Sensor

Solar Converters Inc - PT 12/24-30
30 Amp Charge Controller
12V or 24V Configurable
Power Tracker™ with Maximum Power Point Tracking (MPPT)

Model: PT 12/24-30

Application

This charge controller is used to charge a battery from a PV power source. This charge controller can be ordered with a special float voltage to charge small batteries used for Video or digital cameras or small security camera systems. This unit may also be adjusted to charge a lower voltage battery from a higher voltage power source.

All the listed Power Tracker™ charge controllers with MPPT can charge control a battery of lower voltage. Many of these models can also accept battery or multiple input sources. Special models are available to operate from non-typical PV nominal voltages and charge batteries of different nominal voltages. For example, 72 V nominal panels charging a 36 V battery or any combination of panel and battery so long as the battery voltage is less than the panel voltage. This will be useful where the panels must be a long distance from the battery, allowing wiring with a smaller wire size as the current is reduced. The wire savings alone can easily pay for the controller.

• Single unit 12/24 V operation
  • Will even charge a 12 V battery from a 24 V array or odd voltage CD-TE or amorphous silicon array.
• Real world 15 - 30 % more current than conventional technology into discharged batteries
  • Means faster battery charging or higher system power at similar cost
• Current Limited output - Can operate from multiple input sources
• Maximizes Battery Life
• Dual Float Charge Technique Recommended by battery manufacturers for maximum capacity and lifetime
• Transient Protection
  • Certified to IEEE/ANSI 62.41 1991 4 Kv (simulated lightning strike)
• Low Noise
  • Certified to FCC Section 15J Part B (electrical interference)
• Overvoltage Protection
  • Regulates output at float level even without batteries connected (or bad batteries). Will substantially recover lost battery if recoverable.

** Special units have a suffix of B XX after the part number. The float value of the charge controller is XX. For example PT 12/24 - 3 B8.4 will charge a li-ion battery to 8.4 V from a nominal 12 V solar panel. Note that the charge current increase by the ratio of approx. 15/8.4. Thus a 1 amp 12 V nominal solar panel will charge the li-ion battery at approx 1.78 amps.

• Temperature Compensation:
  • Uses a National LM335Z temperature sensor available from Solar Converters Inc. Model TC-2.
• LVD Control:
  • Short these terminals together with a relay contact, (rated 32 V @ 0.1 A - be careful of dry contacts) or a similiarly rated transistor and the LVD will open; forming an effective load disconnect. Used for Battery Backed Solar Water pumping as a Float Switch Control

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.
