Why Do We Need off Grid Inverter?

The off grid inverter converts DC power (battery, storage battery) into AC power (usually 220V/50HZ sine or square wave). The off-grid inverters have used in many areas, such as new energy systems, but it has not connected to the public grid. Meanwhile, the off-grid inverters are often used as emergency power sources in homes or working offices. Generally, the off-grid inverters convert DC batteries into 220V AC. What is more, it is also used in lodges, cars, and cabins in some remote areas.

What are the precautions when using an off grid inverter?

matters needing attention:

1. When unplugging the electrical appliance in continuous use, be sure to first confirm whether the switch of the electrical appliance has been turned to "off", then unplug the power plug and stop using the off grid inverter.

2. When replacing the fuse of the off grid inverter, be sure to use the fuse of the same model and specification. The use of a fuse or wire other than the specified specification will cause abnormal overheating and fire.

3. Clean the dirt at the  off grid inverter plug-in time to avoid poor contact or abnormal overheating of the converter.

4. When the off grid inverter is used or not used, unplug the off grid inverter from the cigarette lighter socket and keep it properly.

Photovoltaic off grid inverter itself has no reactive power regulation capability?

Photovoltaic off grid inverter has reactive power regulation capability. A microprocessor in the inverter can sense the AC waveform of the power grid, generate voltage according to this waveform and send it back to the power grid.

However, the electricity sent back to the power grid needs a certain proportion of reactive power to make the power of the nearby power grid within the allowable limit. Otherwise, if the proportion of renewable energy in a regional power grid is high, the voltage may rise too high during high power output (such as noon).

If the power of the grid is cut off, the off grid inverterneeds to be off-line with the grid quickly. This is the National Electrical Code (NEC) of the United States to ensure that when the power grid is powered off, the off grid inverter will not provide power to the power grid, so that the workers who repair the power grid will not be electrocuted.

If properly configured, the off grid inverter can enable a family to use its own alternative energy (such as solar or wind power generation) without complicated wiring and batteries. If alternative energy is insufficient, the insufficient part will still be provided by the power grid.

What does the three-stage supplement of off grid inverter mean?

The off grid inverter charging method is divided into three stages:

1. The off-grid inverters are quickly charged with constant current to increase standby power as soon as possible.

2. The off-grid inverter converts to a constant voltage to gradually fully charge the battery, allowing sufficient time for the battery to absorb energy, protecting the battery electrodes, and prolonging the lifespan while avoiding battery overcharging.

3. When the off-grid inverter senses that the battery is full, it will switch to the float voltage to maintain the battery at full capacity for a long time, and automatically detect the battery level, and automatically stop when the charge is completed, stop work and save electricity.
