Multiple Charging and Output modes:

① Charging modes:

 

• PV charge only: In this mode, the battery is charged solely from the solar panels without relying on an external power source. It is suitable for areas without access to the grid and where solar energy is abundant.
• PV (solar) Priority: This mode prioritizes solar power, allowing the system to maximize the utilization of solar energy and reduce dependence on the grid. This helps lower energy costs, especially in areas with ample sunlight, significantly reducing electricity expenses.
• PV+ Utility Charge: This mode provides a more stable power supply. Solar panels take precedence in supplying power, and when solar energy is insufficient or during nighttime, the system switches to grid power. This ensures a continuous and stable power supply even when solar panels are unable to operate or sunlight is limited.

 

② Output modes：

 

• Inverter output：The inverter output is designed to convert direct current (DC) from a power source, such as solar panels or batteries, into alternating current (AC) for use in electrical appliances. This is particularly useful in off-grid or hybrid systems where DC power needs to be transformed into AC power.
• Bypass output：bypass output provides an alternative route for the power to flow directly from the input source to the output load, bypassing the inverter.
