Wall-mounted or stack-mounted installation
Expandable parallel battery system
Suitable for residential and larger energy-storage applications
High-Capacity Energy Storage
The SE-F12C provides 11.8kWh of nominal battery storage from a single unit.
This makes it suitable for larger home solar systems where more battery capacity is required for:
Loadshedding backup
Overnight energy use
Solar self-consumption
Off-grid operation
High-capacity hybrid installations
LiFePO₄ Battery Technology
The battery uses Lithium Iron Phosphate chemistry, providing a stable and durable platform for regular solar charging and discharging.
The supplied specifications state a cycle life of more than 6,000 cycles at 80% depth of discharge.
LiFePO₄ technology is well suited to applications requiring frequent cycling and long-term energy storage.
Smart Bluetooth Monitoring
Bluetooth APP monitoring provides convenient access to battery information and system performance.
This can assist users and installers with monitoring battery status and managing the energy-storage system.
Scalable Battery Design
The SE-F12 platform is designed for parallel expansion.
The supplied information contains two different scalability figures:
One specification states support for up to 64 batteries in parallel
The technical table states a maximum of 32 batteries in parallel
The exact parallel limit should therefore be confirmed against the latest official Deye datasheet before system design or installation.
Flexible Installation
The battery supports:
Wall-mounted installation
Stack-mounted installation
This provides flexibility when designing residential or larger energy-storage systems.

EXCELLENT SERVICE
Great service 👏 thank you
I recently purchased an inverter from The Solar Step, and I couldn’t be more impressed with the experience. I placed my order on Monday, and it was delivered to Pietermaritzburg by Wednesday—incredible turnaround time!
A special shoutout to Kersh, who kept me updated every step of the way. Her expert product knowledge was top-tier, and she went above and beyond by referring me to a dedicated technician who helped verify the exact battery and inverter compatibility before setup.
Top-notch communication, lightning-fast delivery, and genuine customer care. I highly recommend The Solar Step to anyone looking for reliable solar products and expert advice!
