Sail Solar 1MW Hybrid Solar System with 1MWh / 2MWh Energy Storage Battery For Backup Power
Sail Solar a full-set customized hybrid solar energy solution, integrating a 1MW solar system with optional 1MWh / 2MWh lithium battery energy storage system.
This solar storage system supports flexible on-grid, off-grid, and micro-grid working modes. It perfectly solves common power problems for industrial and commercial users, including high electricity costs, grid power instability, frequent power outages and limited grid capacity.
With intelligent peak shaving and valley filling, automatic power switching, and stable energy dispatching functions, the system maximizes solar power utilization rate and effectively reduces overall energy expenses.
It is widely applicable for industrial factory energy-saving transformation, uninterruptible backup power supply, remote mining areas, isolated island micro-grids, commercial buildings and other large-scale renewable energy power projects.

1MW solar modules collect solar energy and transmit DC power to PCS inverters. Excess power charges the 1MWh lithium battery. The PCS converts DC power to AC power to supply factory loads. The 1MWh battery supports 1C charge & discharge rate, which means the battery can be fully charged or discharged within 1 hour. It can interact with the utility grid for peak shaving and backup power supply. All system data is uploaded to the cloud monitoring platform.
Same 1MW photovoltaic array. Two sets of 1MWh battery are connected in parallel to reach a total 2MWh energy storage capacity. Matched with the same 1MW PCS, this system works at 0.5C rate. Full charge or discharge takes approximately 2 hours, delivering longer backup duration and greater energy shifting capacity for heavy-load factories.

FAQ
A: With the same 1MW PV and 1MW PCS inverter power. The 1MW+1MWh version runs at 1C rate, full charge/discharge within 1 hour, suitable for short-time peak shaving and short emergency backup. The 1MW+2MWh version works at 0.5C rate, full charge/discharge takes about 2 hours, delivering longer backup duration and better energy shifting performance for heavy-load factories.
A: It supports on-grid, off-grid and microgrid modes. The system can integrate solar PV, liquid-cooled BESS, utility grid and diesel generators. It can automatically switch working status when grid fails to guarantee continuous power supply for critical loads.
A: We adopt Megarevo hybrid inverters. The 1000kW power is realized by two 500kW Megarevo inverters connected in parallel. This parallel design brings system redundancy, balanced load sharing and fast response during grid fluctuation or blackout.
A: Yes. The system matches with intelligent EMS energy management platform. It stores excess solar power in battery during off-peak hours and discharges at high-tariff peak time, effectively cutting electricity cost and optimizing renewable energy utilization.
A: All key operation data including PV generation, battery SOC, PCS status and load consumption can be uploaded to our cloud monitoring platform. Customers can check real-time data, historical reports and system alarms remotely via laptop or mobile device.
