Description
x11kW Off Grid Solar Power Kit with 15kWh Battery Pelio Storage and JA Solar Panels
This high performance 11kW off grid solar power kit is designed for users who require dependable, high-output energy with the ability to operate fully off grid. It is ideal for remote homes, farms, commercial premises, workshops, and Type 2 EV charging stations where reliable power is required day and night.
With a total of 15kWh battery storage, the system delivers consistent power for heavy electrical loads at any time. High-efficiency solar generation ensures stable performance even during challenging UK and European weather conditions.
The system is scalable and future-ready. All components are engineered to work seamlessly together, reducing installation time while maximising overall efficiency. A full wiring diagram is included to simplify installation and setup.
Note: Pelio uses identical protocol with Pylontech US5000 and all the 48V batteries from Pylon. It is an expandable, stackable solution that works indoors and outdoors. WIFI monitoring and firmware update on the go is avaibale with this battery
Total Grid Independence
This system operates independently from the national grid, giving you full control over your energy production. Solar energy is used to power your loads, with excess energy stored in the batteries for use at night or during low solar conditions.
Optional Grid and Backup Generator Connection
Where available, the system can connect to the grid or a backup generator. This allows battery charging during low cost night tariffs or from a generator during extended periods of poor weather, offering maximum operational flexibility.
Premium Solar Panels for Reliable Energy Generation
The system includes 10 premium 450W JA Solar panels. These panels are designed for long service life and consistent output across a wide range of light conditions, delivering reliable year-round performance.
15kWh Battery Storage Outdoor and Indoor Use
With 20kWh of lithium battery storage, the system supports high charge and discharge rates and long cycle life. This reduces reliance on backup energy sources while ensuring uninterrupted power throughout the day.
Expandable and Future Proof Battery System
Additional battery modules can be added in the future if your energy demands increase. This makes the system a long term investment that can grow alongside your requirements.
Off Grid and Grid-Connected Operation
The system can operate both off-grid and in parallel with the grid for added flexibility. It complies with National Grid Standards of Performance and does not export electricity back to the grid, removing the need for export licences or lengthy approval processes.
When connected to the grid, the system operates like a standard appliance, drawing power only when necessary to charge the batteries, typically during low-tariff periods.
