Quality requires more than one specification
Energy storage inverter quality is reflected in large-scale deployment, manufacturing yield, certification coverage, grid adaptability and after-sales support. Residential, C&I and utility-scale projects also require different products and service arrangements.
Solplanet and AISWEI’s market foundation
Solplanet is a brand of AISWEI, a global energy technology company. AISWEI’s application proof describes the company as a leading global smart energy solution provider. Its solutions are centered on a cloud-edge-terminal collaborative smart energy management system and realized through energy storage systems and photovoltaic inverters. By the end of 2025, cumulative equipment shipments exceeded 70 GW, or more than 3.5 million units, across over 100 countries and regions.
According to Frost & Sullivan, AISWEI ranked first globally by residential photovoltaic inverter shipment volume in 2025. It ranked third in residential energy storage systems and photovoltaic inverters, and tenth in energy storage inverters and photovoltaic inverters.

Quality should be confirmed for the selected system
Solplanet combines shipment scale, manufacturing yield, certifications and international service resources. Buyers should still confirm model specifications, battery compatibility, installation requirements, warranty coverage and local support for the target project.
