Installation

Unpack and inspect contents. Ensure proper mounting location.

  1. Mount the unit: Choose a well-ventilated, dry location away from heat sources.
  2. Connect solar panels: Positive and negative terminals to PV INPUT terminals.
  3. Connect battery: Positive and negative terminals to BATTERY terminals observing polarity.
  4. Connect load: If applicable, connect load to LOAD OUTPUT terminals.
  5. Connect temperature sensor: Attach to battery terminal for accurate temperature compensation.

WARNING! Disconnect all power sources before installation. Ensure all connections are tight and secure.

First-Time Setup

Power on the system; follow display prompts for initial configuration.

  1. Select battery type: Use MENU button to choose battery chemistry (LiFePO4, AGM, Gel, Flooded).
  2. Set charging parameters: Configure bulk/absorption/float voltages according to battery specifications.
  3. Configure load output: Set timer or voltage-based load control if needed.
  4. Set system voltage: Unit will auto-detect 12V/24V; verify on display.
  5. Calibrate temperature sensor: Ensure proper reading for compensation.

CAUTION! Incorrect battery settings may damage batteries. Refer to battery manufacturer specifications.

Specifications

Controls and Settings

Access settings via front panel buttons and LCD display.

Front Panel: POWER button, MENU button, UP/DOWN navigation buttons, ENTER button.

Display Information: PV voltage/current, Battery voltage/current, Battery state of charge, Temperature, Error codes, Load status.

Menu Settings: Battery type selection, Charging voltage adjustment, Load control mode (Timer/Voltage/Manual), System voltage setting, Temperature compensation, Communication setup, Factory reset.

Connecting Devices

Solar Panels: PV INPUT terminals. Battery: BATTERY terminals. Load: LOAD OUTPUT terminals. Temperature Sensor: Dedicated port. Communication: RS485/CanBus port.

  1. Ensure all devices are disconnected before making connections.
  2. Use appropriate cable sizes (minimum 6mm² for 40A model).
  3. Connect solar panels first, then battery, then load.
  4. Use proper fusing as per local electrical codes.

Tip: Keep cable runs as short as possible to minimize voltage drop.

Operation Modes

The controller operates in several automatic modes:

  1. Bulk Charging: Maximum current until battery reaches absorption voltage.
  2. Absorption Charging: Constant voltage charging for battery saturation.
  3. Float Charging: Maintenance charging at lower voltage.
  4. Equalization: Periodic overcharge for flooded batteries (if enabled).
  5. Load Control: Automatic load switching based on battery voltage or timer.
  6. Sleep Mode: Low power consumption when no solar input available.

WARNING! Do not disconnect battery while solar panels are producing power.

Protection Features

Multiple protection circuits ensure safe operation:

Care & Maintenance

Regular inspection ensures optimal performance.

  1. Monthly: Check all connections for tightness and corrosion.
  2. Quarterly: Clean unit exterior with dry cloth; ensure ventilation not blocked.
  3. Annually: Verify calibration and settings; check for firmware updates.

CAUTION! Do not open the unit; no user-serviceable parts inside. Contact qualified technician for internal service.

Troubleshooting

SymptomPossible CauseCorrective Action
No displayNo battery powerCheck battery connections; verify battery voltage > 10V.
Not chargingSolar panel issuesCheck PV connections; verify panel voltage > battery voltage +2V.
Over-temperature warningPoor ventilationImprove airflow; reduce ambient temperature if possible.
Load not workingLoad protection triggeredCheck for short circuits; reset by disconnecting and reconnecting load.
Communication errorWiring/configurationCheck communication cable; verify baud rate and address settings.
Low efficiencyWiring losses/mismatchCheck cable sizes; ensure PV voltage is within MPPT range.

Reset: Hold MENU + ENTER for 10 seconds to factory reset (settings will be lost).
