4-digit LED or LCD showing Volts (V), Amps (A), Watts (W), and Capacity (Ah) Cooling: Built-in fan for thermal management 🕹️ Basic Operation Guide Primary Controls SET Button: Toggles between setting voltage and current. Up/Down Arrows: Increases or decreases the selected value. OK Button: Turns the output ON or OFF . Indicators: OUT: Active output. CV: Constant Voltage mode. CC: Constant Current mode (active during current limiting). ⚙️ Advanced Programming Data Storage and Recall The device can store up to 10 groups of settings (0–9).
This guide was compiled using manufacturer datasheets, verified specifications from resellers (Easytronics, CompactTool, Radiovin), and user community insights. Always refer to the physical documentation included with your specific unit, as minor revisions may occur between production batches.

10 programmable storage locations (M0 through M9) Board Layout and Interface Overview bst900w manual
The BST900W can be configured to start automatically upon power-up.
If the exact is impossible to find, you can safely use a manual from a functionally identical 900W inverter/charger . Look for these keywords in an alternative manual:
Instead of typing bst900w manual alone, try:
The dedicates a full page to the LCD symbols. Here is the cheat sheet: 4-digit LED or LCD showing Volts (V), Amps
Check with a multimeter that your power source provides at least 8V DC at the terminal blocks, and double-check that IN+ and IN- are wired correctly. The module shuts down or resets under heavy loads
The is a high-power, digitally controlled step-up power supply module . It allows users to boost low DC input voltages ranging from 8V to 60V up to an adjustable output of 10V to 120V at currents up to 15A . Controlled by an integrated high-speed microcontroller (like the STM8S ), the module features a multi-digit LED display providing real-time data on voltage, current, power, and capacity.
The LED screen will initialize and display the current default output voltage. The output is by default for safety. Setting the Output Voltage
Check if the output is turned on (the OUT LED should be illuminated). If it is on and the voltage won't rise, ensure your target set voltage is higher than your source input voltage. Indicators: OUT: Active output
The BST900W is a power amplifier, and I'd be happy to help you find the manual. Here are a few options:
Press the SET button again to save the parameters. The display will stop flashing.
