What Are the Benefits of Choosing Off Grid Inverters?
The inverter is a important component of a solar power system. Off grid inverters can be used in remote areas without grid coverage, such as island, deserts, plateaus, and deep forests, to provide power needs anytime, anywhere. Photovoltaic off grid inverters are power conversion devices that convert input DC power into push-pull boosting, and then invert DC power into 220V AC power through the inverter bridge SPWM sinusoidal pulse width modulation technology. Let Microtek off grid solar inverter supplier explore for you.
How to use off grid inverters and on-grid inverters?
On-grid inverters can be used directly as off grid inverters. On-grid inverters directly supply energy to the grid, so they need to track the frequency and phase of the grid, which is equivalent to a current source. Of course, it is said that some inverters have low voltage ridethrough capability and can do PQ regulation. The off grid inverter is equivalent to establishing an independent small grid, mainly controlling its own voltage, which belongs to a voltage source. On-grid inverters do not need to store energy, but energy cannot be controlled. With the increasing amount of photovoltaic power generation, the electricity it converts can be sent to the power grid.
The benefits of choosing off grid inverters
On-grid inverters directly supply energy to the grid, so tracking the frequency and phase of the grid is equivalent to a current source. The off grid inverter is equivalent to establishing an independent small grid, mainly controlling its own voltage source. On-grid inverters do not need to store energy, but cannot be regulated. Off grid inverters generally require energy storage and do not supply the grid, and the grid has no right to intervene.
Off grid inverters are used in photovoltaic off grid power generation systems, mainly converting DC into AC for AC loads. Photovoltaic off grid inverters themselves do not have energy storage functions and usually need to be used with batteries to start up normally. However, batteries are expensive and have a short lifespan, making the cost of the entire photovoltaic off grid power generation system too high.
The off grid inverter can work independently without connect grid, correspond to a independent small grid, mainly controlling its own voltage source. It can bear resistive, capacitive, motor inductive and other loads, respond quickly and resist interference, and have strong adaptability and practicality. It is the preferred power product for power outages and outdoor power sources.
Photovoltaic off grid inverters are suitable for power systems, communication systems, railway systems, ships, hospitals, shopping malls, schools, outdoor and other places. They can be connected to the grid to charge the battery. Also they can be set as battery priority or grid priority. In general, off grid inverters need to be connected to batteries because photovoltaic power generation is unstable and loads are unstable. Batteries are needed to balance the energy. Not all photovoltaic off grid inverters need to be connected to batteries.
