Ordering

Hardware

  1. Each Sentry-1202W2 monitors 1 string of 12x2V.
    If a system has multiple strings, order one unit for each string.
    Each unit comes with 2 temperature sensors for ambient and pilot temperature.
  2. Unit comes with onboard Ethernet DTU. If external wireless DTU is selected, an activated SIM card (GSM) is needed.
  3. Order O-ring leads, specify 6mm (1/4"), 8mm(5/16") or 10mm(3/8"). 
  4. Order current sensor if needed. Default window size: 15mmx20mm, close loop 300A (peak current 600A). Other size/range and split-core sensor may have longer lead time.
  5. A HMI touch display is recommended for field service. 
  6. Optional 12-conductor 20AWG cable, calculate the length for order.

Software

Battery Analyzer Software license comes with hardware order.
