1.Residential Rooftop Projects
Application Description: Installed on the roofs or exterior walls of villas, self-built houses, and new rural homes. Solar energy is used to power household loads, with excess electricity sold to the utility grid.
Reasons for Choosing This Inverter:
IP66 Rating: Can be fully exposed outdoors, fearless of sun, rain, and dust, reducing failure rates and extending service life.
Battery-Less: Simple system structure, lower initial investment cost, minimal maintenance, and no concerns about battery replacement.
Economics: The "self-consumption, feed-in surplus" model effectively reduces household electricity bills and can generate income from electricity sales.
2.Commercial and Industrial (C&I) Rooftop Projects
Application Description: Installed on the corrugated steel or concrete flat roofs of factories, warehouses, shopping malls, and large supermarkets to build distributed photovoltaic (PV) power stations utilizing large roof areas.
Reasons for Choosing This Inverter:
IP66 Rating: Industrial environments may have more dust, oil fumes, or humidity issues; the high protection level ensures stable operation.
Economies of Scale: The battery-less design reduces the complexity and cost of large-scale deployment, resulting in a shorter investment payback period.
Matches Demand: Commercial and industrial facilities have high electricity consumption during the daytime, which aligns well with the solar power generation curve, leading to a high self-consumption rate and significant energy savings.
For C&I rooftop projects, our single phase on grid inverter is an excellent choice, providing robust performance, cost efficiency, and high energy savings.
3.Agricultural and Aquacultural Applications
Application Description: Installed on agricultural greenhouses, irrigation pump stations, farms (e.g., piggeries, chicken coops), and floating platforms for fishery-photovoltaic complementary projects.
Reasons for Choosing This Inverter:
IP66 Rating: Agricultural environments are often humid, dusty, and may even have corrosive gases (e.g., on farms). The IP66 rating offers strong adaptability to such harsh conditions.
Reduce Operating Costs: Provides low-cost electricity for agricultural equipment like irrigation pumps, climate control, ventilation, and lighting, directly reducing production costs.
II. Niche Advantage Scenarios: Leveraging IP66 for Harsh Environments
4.Public Utilities and Infrastructure
Application Description: Installed in open outdoor areas or on roofs of facilities like highway toll stations, service areas, streetlight control cabinets, communication base stations, and wastewater treatment plants.
Reasons for Choosing This Inverter:
Environmental Adaptability: These facilities are often unattended and in open environments. The IP66 protection ensures long-term, reliable operation with minimal maintenance.
Green Initiative & Emission Reduction: Helps public facilities achieve partial clean energy substitution, providing a positive social demonstration effect.
5.Small-Scale Commercial Distributed Projects
Application Description: Installed on canopies of gas stations, parking lot shelters, and supports for outdoor billboards.
Reasons for Choosing This Inverter:
Space Utilization: Makes efficient use of idle outdoor canopy space to generate economic benefits.
Durability: Fully exposed to road dust, vehicle exhaust, and weather, the IP66 rating is an essential feature.
