– Additionally, off grid solar inverters can be used to power other appliances besides solar power systems, making them an ideal choice for small off-grid energy systems.
Understand the Different Modes
Different working modes are available for off-grid inverters, such as mains, battery priority, and photovoltaic. Mains inverters are able to supply power seamlessly without any interruption, while battery backup inverters provide energy backup in case of power failure. The photovoltaic mode uses solar energy only and draws power from solar panel output directly without using grid energy. The cost of each mode varies depending on the capacity of inverter and its features such as backup system and DC-to-AC voltage conversion
You should understand the different working modes before buying an off-grid inverter to ensure you get the right product for your needs.
Pv panel and battery preferred mode
Off-grid inverter-chargers can provide a high surge and peak power output, which is ideal for handling high inductive loads. Off-grid inverter-chargers are also energy efficient as they can absorb electricity from the battery and release it for the load. In solar systems, hybrid inverters are designed to draw from solar power when there is solar energy available, but can also charge the battery when there is excess energy. Off-grid solar systems can have three charging modes: electric charging, photovoltaic charging, and mains and photovoltaic charging. This versatility allows off-grid solar system users to choose the best mode of charging to suit their energy needs and budget.
Output: Off-grid inverter-chargers are versatile energy storage devices that can handle a range of applications and generate power in several ways. They are perfect for applications where power output must be regulated or variable (e.g., solar power system). 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?

Maximize Efficiency with the Optimal Mode
An inverter is a vital part of solar energy system. It is used to convert the DC output from solar panel into AC power for household appliances. Off-grid inverter output voltage and frequency should match the load requirements and usually the same as your country standard supply voltage/frequency. There are two types of inverters – off-grid inverters and hybrid inverters.
Off-grid inverters are able to draw power from grid for backup when necessary whereas hybrid inverters can extract power from grid when there is surplus PV power. An inverter is necessary when setting up solar panels with a capacity greater than five watts, as it helps in regulating the output of solar panel. Besides, it is also essential for charging battery bank.
Pros and cons of using an off grid inverter in different modes
An off-grid inverter is a one-directional power flow inverter designed for solar energy system. It’s used to convert solar energy from PV panel into usable power in an AC output voltage.
Off-grid inverters are able to handle solar energy of varying output and voltage levels without the need of extra power input. This means they can supply the required power to a household regardless of the solar energy system’s output and voltage level.
When solar energy system is connected with grid-tied inverter, it acts as a buffer, smoothing out the output voltage by regulating the incoming solar energy supply. A hybrid inverter can handle solar energy of varying output and voltage levels while also acting as a battery charger or power bank in case of excess solar energy supply. Adding hybrid inverters into solar system demands an expensive re-work of whole system as hybrid inverter ensures constant power supply and optimal utilization of renewable resources
How to choose the working mode of the off grid inverter?
