Description
Deye’s solar backup power systems are intelligent lithium battery storage solutions designed to provide reliable emergency power to homes and businesses.
As a leading solar backup power systems manufacturer in China, Deye leverages innovative technologies to produce robust systems that can store solar energy and provide power during grid outages.
These complete solar backup power systems consist of high-quality lithium iron phosphate battery packs paired with advanced battery management systems. The battery packs come in three sizes – 1540mm x 385mm x 540mm, 1760mm x 385mm x 540mm, and 1980mm x 385mm x 540mm to meet different energy storage needs. Depending on the size, the systems can store between 137kWh to 293kWh of solar energy for later use as backup power.
A key benefit of Deye’s solar backup power systems is their long lifecycle. Under standard test conditions of 90% depth of discharge, 0.2C charge and discharge at 25°C, the batteries retain 70% of its capacity after 6000 cycles. This translates to over 20 years of reliable backup power for most homes. The advanced battery management system also allows real-time monitoring of battery status via an app.
These robust floor-mounted solar backup power systems are designed for convenient installation and maximum space savings. They work seamlessly with Deye’s GB-S series solar inverters, which efficiently convert the DC power from the batteries into usable AC power for your home grid. With islanding protection, the systems can safely disconnect from the grid during outages and provide continuous power from the battery bank.
In summary, Deye’s high-quality solar backup power systems provide intelligent and reliable emergency power for homes and businesses using renewable solar energy. As a solar backup power systems leader, Deye leverages innovative lithium battery and power electronics technologies to build systems that can store abundant solar power and keep your appliances running even when the grid fails.
