Description
xComplete 11kW Off Grid Solar System With 15kWh LiFePO4 Batteries
This complete 11kW off grid solar system is designed for homes, farms, workshops, remote buildings and commercial sites that need reliable power without depending on the grid. The kit includes a powerful 11kW Conversol MAX-II inverter charger, 10 x JA Solar 465W panels, 15kWh of lithium battery storage, PV protection, battery protection, cables, monitoring and mounting equipment.
The system is supplied as a professional ready-to-install package, with carefully selected components designed to work together safely and efficiently. A wiring diagram is included to support installers and competent DIY users during installation.
Bespoke Ready-To-Install 11kW Off Grid Solar Kit
This solar kit has been designed by Voltacon technical experts to provide a balanced off grid power solution with high inverter output, reliable lithium storage and premium JA Solar PV modules. It is suitable for customers who want a complete package instead of sourcing individual parts from multiple suppliers.
The 11kW MAX-II inverter charger provides strong single-phase AC output and twin AC output functionality, allowing essential and non-essential loads to be managed more effectively. The included 15kWh LiFePO4 battery bank provides dependable energy storage for night-time use, backup power and daily solar charging.
Complete Solar Solution With Room To Expand
This system includes 10 x JA Solar 465W monocrystalline panels, giving a total solar array size of 4,650W. The inverter allows future expansion, making this kit suitable for customers who want to start with a professional off grid system and increase solar or battery capacity later.
The lithium battery storage is supplied as 3 x 5kWh LiFePO4 battery modules, giving a total capacity of approximately 15kWh. The battery bank can be expanded further, subject to inverter settings, battery compatibility and installation requirements.
As this is an off grid solar photovoltaic system, it does not export energy back to the grid. In most cases, this means there is no requirement for grid export approval from the electricity supplier. The system is designed to power loads independently from solar panels, batteries and optional AC charging input where required.

Professional Off Grid Power For Demanding Loads
The 11kW inverter output makes this system suitable for demanding electrical loads such as pumps, tools, lighting, refrigeration, heating controls, office equipment and general household appliances. The twin AC output design helps separate priority loads from less essential loads, improving control and energy management.
The included lithium batteries are designed for deep-cycle solar storage and long service life. LiFePO4 battery technology is safer, more efficient and longer lasting than traditional lead-acid battery banks.
Solar Assistant Remote Monitoring
Solar Assistant monitoring is included with the system, allowing you to monitor inverter performance, battery status, solar production and load consumption remotely. This helps you understand how the system is performing and allows easier system management.
Mounting And Customisation
The kit includes an adjustable angle mounting structure. If your project requires a different type of mounting system, please contact us before ordering and we can review the required arrangement.
The lithium batteries may also be exchanged for Pylontech US5000 batteries at no extra cost, subject to stock availability and final system configuration.
Typical Applications
- Off grid homes and remote properties
- Farms and agricultural buildings
- Workshops and garages
- Cabins, lodges and holiday homes
- Commercial backup power systems
- Solar battery storage for independent power supply
Important Installation Notice
