As the core device of the PV power generation system, the inverter converts the variable DC voltage generated by PV solar panels into commercial frequency AC power.
Common inverters on the market include central inverters and string inverters.
MPPT performance is the key index of an inverter. In practice, the power generation of solar modules is affected by factors such as the type of solar panel, weather, temperature, and irradiance. These factors challenge the MPPT performance of inverters.
Kewell PV solution simulates inverter power generation and grid connection in all weather conditions, providing professional testing solutions for PV customers/testing institutes.

Green and low-carbon development is now a global consensus, and many countries around the world have put forward clear goals. Central inverters are generally higher than 500kW in power, and the input and grid-connected power is even higher in actual testing, creating a great demand for high-efficiency test equipment.

Kewell commercial and industrial PV inverter solutions have a test efficiency of up to 95%, which reduces CO₂ emissions by 60% compared to the grid frequency solutions, helping PV companies to realize their carbon emission targets.

As the application of energy storage grows in the power system, its role and potential has been gradually released. It plays an important role in energy scheduling, peak load shifting, smooth output of renewable energy, microgrid support and other fields.

With rich technical experience and extensive applications in energy storage, Kewell provides customers with safe and reliable PCS test solutions.

Household PV and storage systems have flexible load regulation capability. During the period of low power consumption, the battery packs of household energy storage will charge by themselves; combined with PV, they form hybrid, coupled and off-grid household PV + storage systems.
