230V 3Kw 5Kw 10Kw 48V Off-Grid Inverter For Solar Energy Storage System

The Difference Between On-Grid Inverters And Off-Grid Inverters

Grid-connected inverters are generally divided into photovoltaic power generation grid-connected inverters, wind power grid-connected inverters, power equipment power generation grid-connected inverters, and other power generation equipment power generation grid-connected inverters. The characteristic is that the power of the system is high and the cost is low.

Grid-connected inverters are generally used in large-scale photovoltaic power station systems. Many parallel photovoltaic strings are connected to the DC input end of the same centralized inverter. Generally, three-phase IGBT power modules are used for high-power ones, and the power is relatively low. The small ones use field effect transistors while using a DSP conversion controller to improve the quality of the generated power, making it very close to a sine wave current.

The biggest difference in the grid-connected inverter is that it does not do any battery storage. The direct current generated by the solar panel is directly converted into alternating current through inversion and directly connected to the public power grid. Regulations and policies, otherwise grid connection cannot be provided.

Off-grid inverters are generally complete system solutions in modular components, consisting of manageable building blocks: inverter, solar charge controller, automatic generator starter module, and system control board.

As the name implies, the off-grid inverter is a system that is separated from the public grid. The direct current generated by the solar panel is first stored in the battery, and then the battery is transported to the off-grid inverter for inversion. Load use can also be returned to battery storage, which is more suitable for those remote areas without power network coverage, such as deserts, plateaus, and deep forests, and can provide power needs anytime and anywhere.
