PT 12/24-30


30 Amp Charge Controller

Model: PT12/24-30

12/24 V @ 30 Amps


 


This unit has Maximum Power Point Tracking and voltage conversions. What is Maximum Power Point Tracking (MPPT)?

FEATURES

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

Maximizes Battery Life

  • Dual Float Charge Technique
  • recommended by battery manufacturers (1) for maximum capacity and lifetime

Transient Protection

Low Noise

Overvoltage Protection

  • Regulates output at float level even without batteries connected (or bad batteries). Will substantially recover lost battery if recoverable.

REMOTE INTERFACE

Temperature Compensation:

  • Uses a National LM335Z temperature sensor available from Solar Converters Inc.

LVD Control:

  • Short these terminals together with a relay contact, (rated 32 V @ .1 A – be careful of dry contacts) or a similiarly rated transistor and the LVD will open; forming an effective load disconnect.
