Need a Smarter Rooftop Energy Solution? SUNDTA’s 551.25 kW PV + Storage Project in Anhui Is Ready!

SUNDTA has successfully completed and commissioned a distributed rooftop photovoltaic project in Anhui Province, China. With a total capacity of 551.25 kW, the project combines rooftop solar generation with battery energy storage and uses SUNDTA 700 W N-type solar panels, SUNDTA 51.2 V 200 Ah rack-mounted lithium batteries, and Solis 50 kW energy storage inverters. The project has entered operation after successful commissioning, demonstrating SUNDTA’s integrated capability in solar and storage project delivery.

The project utilizes 788 N-type 700W solar panels, 11 Solis 50kW energy storage inverters, and two sets of rack-mounted lithium batteries (totaling 54 units); this configuration supports peak shaving and valley filling, load shifting, and an increased self-consumption rate for the rooftop solar energy.

The equipment selection reflects a focus on efficiency, safety, and long-term reliability. SUNDTA 700 W N-type panels offer high conversion efficiency and strong power generation performance, helping maximize limited rooftop space. The wall-mounted lithium batteries are compact, easy to install, and suitable for distributed applications, while the Solis 50 kW energy storage inverters provide stable conversion and intelligent energy management. Together, these products form a flexible solar-plus-storage system that can respond to changing load demand and improve energy resilience.

The Anhui project also highlights SUNDTA’s service strength. SUNDTA not only has a professional sales team capable of addressing the needs of overseas markets, but also maintains an experienced engineering and O&M team with rich experience in building photovoltaic projects. From initial site assessment and system design to equipment selection, construction guidance, commissioning, and operation, SUNDTA’s engineering team supports the full project lifecycle. This practical experience helps reduce risks, shorten delivery time, and ensure stable system operation after grid connection.

For overseas customers, SUNDTA can provide remote technical support. Through remote monitoring, online diagnosis, parameter configuration guidance, troubleshooting suggestions, and technical training, SUNDTA’s team can assist international partners even when travel is not immediately possible. This remote support capability is especially important for distributed rooftop projects, where installation conditions, grid rules, and customer requirements can vary from one market to another. It allows SUNDTA to respond quickly and help partners solve technical issues efficiently.

SUNDTA welcomes global customers to visit China to see its factory and project sites in person. Visiting the factory allows customers to understand production processes, quality control, and product testing, while visiting operating projects such as the Anhui rooftop installation provides direct insight into real performance and installation quality. SUNDTA also offers one-to-one customized solar and energy storage solutions, designing configurations according to specific customer needs, local conditions, and business goals. With reliable products, professional sales support, experienced engineering and O&M teams, and responsive remote technical service, SUNDTA is committed to working with global partners to deliver bankable photovoltaic and energy storage solutions.
