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. The exceptional small size of this unit makes it extremely portable and able to fit almost anywhere in the user equipment. This unit may also be adjusted to charge a lower voltage battery form 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.

Note: For optimal Maximum Power Point Tracking performance, it is recommended that MPPT charge controllers be used in conjunction with uniform solar arrays consisting of multiple, identical solar panels. MPPT charge controllers will still work with mixed arrays, but at reduced efficiencies, which defeats the whole point of MPPT technology. These devices were designed to calculate the most efficient charging characteristics given the assumption of a uniform array. Mixed arrays, by definition throw this calculation off.

Features

  • Single unit 48V operation
  • Real world 15 - 30 % more current than conventional technology into discharged batteries.
    • Current Limited Output - Can operate from multiple input sources
    • Means faster battery charging or higher system power at similar cost
  • 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 48-8 B36 will charge a 36 V battery to 42 V from a nominal 48 V solar panel. Note that the charge current increase by the ratio of approx. 60/36. Thus a 1 amp 12V nominal solar panel will charge the li-ion battery at approx. 1.6 amps.

  • Temperature Compensation:
    • Uses a National LM335Z temperature sensor available from Solar Converters Inc. as M odel 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.
