CHARGING CURVE

Bulk: This is the first stage (MPPT) where the battery is in a low charge state. During this stage the controller delivers all of the available solar power to the Battery system.
Absorption: In this stage (Constant Voltage) the controller charges at a constant voltage as the amount of current required to charge the battery is decreasing. The constant voltage regulation prevents overheating and excessive battery out-gassing; this stage will end when the battery charge current reduces to below 4 Amps OR after 4 hours of entering absorption mode.
Float (Maintenance): After the battery is fully charged, the controller reduces to a lower Constant Voltage setting to maintain the Battery (also called trickle charge).

PROTECTION FUNCTIONS

• Overcharge protection

• Battery under-voltage protection

• Solar panel reverse current protection
  The following installation faults do not destroy the controller. After correcting the fault, the device will continue to operate correctly:

• Overcharge protection

• Reverse polarity protection of panel and battery

• Automatic electronic fuse

• Open circuit protection without battery

• Reverse current protection at night

MAINTANANCE

The controller is maintenance-free. We strong suggest that all components of the PV system must be checked at least annually,

• Ensure adequate ventilation of the cooling element
• Check the cable strain relief
• Check that all cable connections are secure
• Tighten screws if necessary
• Terminal corrosion

ERROR MESSAGES

Caution! Please do not open the controller or attempt to replace components when troubleshooting. Improper maintenance can be hazardous to the user and the system.
If the controller detects errors or unauthorized operating states, it shows error codes on the display. Error codes can generally be differentiated, whether there is a temporary malfunction, e.g. regulator overload or a more serious system error that can be remedied by appropriate external measures.
Since not all errors can be simultaneously displayed, the error with the highest error number (priority) is displayed. If several errors are present, the second error code is displayed after remedying the more significant error.
The following meaning is assigned to the different error codes:

Fault Codes

• E1: Battery reverse connection / reverse polarity (please correct).
• E2: Battery open circuit protection / low DC voltage (battery not connected / or battery voltage too low, <8V/18V)
• E3: Battery over current protection (circuit has constant current function; the machine may be damaged if there is a problem).
• E4: Load over current / short circuit protection (error 10S, turn on the load after eliminating the error).
• E5: Battery over voltage (battery damaged or battery voltage too high,>15V/31V).
• E6: PV (solar) input over voltage protection. (PV voltage exceed the limit)
• E7: Over temperature protection, automatically stop charging when heat sink temperature ≥ 90°C; resume when temperature ≤ 60°C.
• E8: PV reverse connection (please check voltage and fix) – please ensure polarity is correct.

Remark: Please eliminate the fault according to the error code. If the regulator does not respond after the error is eliminated remove the power source (battery). If the error still persists the device may be damaged and may need after sales service.

Temperature Compensation/Temp Sensor

(Only for STD/Lead Acid Battery)

1. The system will automatically adjust the float voltage according to the ambient temperature. If the external temperature probe is not connected (or the external temperature is <40°C), use (temperature ≥ 20°C – 5°C) by default.
2. The voltage may vary when the input energy is insufficient to stabilize the energy required for the float charging.
   • For 12V/24V batteries, when the external probe temperature ≤ 0°C, the float charging voltage is 14.1V/28.2V
   • For 12V/24V batteries, when the external probe temperature is 0°C~20°C, the float charging voltage is 13.8V/27.6V
   • For 12V/24V batteries, when the external probe temperature ≥ 20°C, the float charging voltage is 13.5V/27V

Remark: If internal head sink temperature exceeds 75 Deg C, the device shall go into approximately half power mode. Shall resume normal operation when internal head sink drops below 70 Deg C.
If internal head sink exceeds 90 Deg C, the device shall turn off. Shall resume charging again when temperature drops below 60 Deg C.
