Based on the excellent performance of the previous generation of products, G2 Series Energy Storage Inverter has optimized the volume and weight of the product, making it more compact and lightweight, reducing labor installation costs by 50%, and the full load efficiency has been increased by 0.5%. It is compatible with 18.5A solar panels and can support up to 12kW of power output. This allows for greater flexibility in system design and integration, users can expand the capacity according to their energy storage needs. Moreover, it supports 6 machines in parallel.
Save more installation, commissioning costs
Reduce the use of fossil fuels and be more environmentally friendly
Increase the penetration of renewable energy
Continuous and stable power supply
PV expansion will be more convenient in the future
