Solar Charge Controller For IOT

Solar power backup for remote IoT devices

Description

A small solar charge controller for IoT devices in the field where mains power is not available. Field instruments can be made fully solar powered using this charge controller. Battery may also be installed inside IP-67 enclosure for protection from rain and dust. The charge controller with battery acts as power backup device with is 100% powered using solar energy. LED indications are provided to display battery charging, DC load, and faults. It is a plug and play system and requires minimum setup time in field. The charge controller incorporates all protections including reverse battery, reverse PV, overload, short-circuit, etc. to reduce field failures.

9 Green LED Indications
  LED_G blinks once every 5 seconds Battery connected, Not charging
  LED_G blinks once every 2 seconds Battery I_chg <= 0.25Amp current
  LED_G blinks twice every 2 seconds Battery I_chg > 0.25Amp current
  LED_G solid on Battery is fully charged
  LED_G off Battery disconnected / Fully discharged at night
10 Yellow LED indications
  LED_Y blinks once every 2 seconds Low Battery
11 RED LED indications
  LED_R blinks 250msec on/ 250msec off Battery connected in Reverse Battery connected in Reverse
  LED_R blinks twice every 2 seconds Load overload shutoff
  LED_R solid on Battery high cut (As soon as battery voltage reaches < 14.2V (+/- 0.2V), LED_R turns OFF
12 Charging Methodology
  Conversion technology: MPPT (Maximum Power point tracking)
  Charging Mode: CC-CV
  CC Mode: (During battery charging) Charges the battery with the maximum constant current available from the solar panel till battery voltage < 13.80V, I_chg tapers off to 0A as V_batt rises to 14.2V
  CV Mode: (Once battery gets fully charged) Charges the battery with the required current to maintain it to 14.2V
  Charging Efficiency: >= 91%
13 Protections:
  Solar Panel Reverse protection
  Battery Reverse protection
  Battery Overcharging protection
  Battery Deep discharge protection
  Surge Protection
  Load short circuit protection
  Open circuit protection
Note Charge controller dynamically adjusts Maximum power point to extract the maximum possible power available from the solar panel under all weather conditions.
