When selecting off-grid inverter-chargers, it is important to ensure they have enough capacity to support the type of off-grid system you have in mind.

Grid Power priority mode

In grid power priority mode of off-grid inverter, it can automatically draw power from the grid when necessary. This typically takes place in case of a power failure or when backup energy is needed. When grid power priority mode is enabled, the inverter will draw power from the grid for backup. The inverter will remain in standby mode outside of the set time period, preserving energy and efficiency. Grid power priority mode is useful for regular supply of loads such as electrical heating. It ensures that vital appliances are powered during peak demand periods without over-drawing on household energy resources. The output voltage of an inverter should correspond to the load nominal voltage, typically 240 volts in Europe and Africa and 120V in USA.

Auto Balance Mode

An off-grid inverter that is operating in Auto Balance mode can ensure optimal energy consumption by acting as a battery inverter. This feature of an off-grid inverter allows users to set time-controlled inverter operation, e.g., when energy demand fluctuates during the day. An off-grid inverter that is operating in Auto Balance mode can help balance energy output and energy demand automatically within a system. This feature helps mitigate energy storage system issues, such as battery degradation due to over-discharge or over-charge. To ensure the system remains stable and efficient, off-grid inverters in Auto Balance mode allow users to set parameters such as voltage and power output per period. In addition, Auto Balance mode in off-grid inverters provides mobile app cloud monitoring systems to track system output and receive notifications on the status of the system.

How to know the working mode of the off grid inverter?
