Solis 10/15kW Hybrid PLUS AI Optimised Inverter with Fogstar Energy 48.3-64.4kWh Modular Battery Stack
Solis 10-15kW Three-Phase Low Voltage Hybrid Inverter
The Solis 10-15kW Three-Phase Low Voltage Hybrid Inverter is a powerful and flexible energy storage solution designed for advanced residential and light commercial applications. Engineered for stability, scalability and intelligent backup, this inverter delivers reliable performance even in challenging grid or generator conditions.
With support for high-current PV modules, dual backup outputs and microgrid operation, it provides installers and system owners with a future-ready platform for modern solar-plus-storage systems across the UK.
Advanced Backup & Energy Security
This inverter is generator-compatible, allowing extended backup duration during grid outages. It supports dual backup ports, enabling intelligent separation of critical and non-critical loads for optimal energy management. With a rapid response to overloads and weak grid conditions, connected loads remain stable and uninterrupted.
Key backup capabilities include:
-
Generator compatibility for extended outage protection
- AI Optimised cloud-based, automated energy management assistant
-
Dual backup ports for intelligent load prioritisation
-
200% overload capability for up to 10 seconds
-
Stable operation during weak grid or generator fluctuations
High-Performance PV & Battery Integration
Designed to handle today’s high-power PV modules, the inverter supports a maximum PV input current of 20A, making it compatible with panels from all major manufacturers. On the battery side, a high DC charge and discharge capacity allows greater utilisation of surplus solar generation.
Energy handling features include:
-
Support for high-current PV modules across any brand
-
Battery DC charge/discharge current up to 290A
-
Increased self-consumption of solar energy
Microgrid & Load Flexibility
Multiple units can operate together to form a microgrid, enhancing resilience and scalability for larger installations. The inverter also supports unbalanced and half-wave loads on both grid and backup ports, ensuring compatibility with a wide range of real-world electrical loads.
System flexibility highlights:
-
Multi-inverter microgrid capability
-
Supports unbalanced and half-wave loads
-
Reliable performance in complex three-phase systems
The Fogstar Energy Modular Battery Stack (FE51.2-48.3) is a high-capacity, low-voltage (51.2V) LiFePO₄ energy storage system designed for residential, commercial and light industrial applications.
Built from 3-4 X 16.1kWh battery modules, and managed by a single top-mounted control unit that operates the system as one fully integrated solution.
With the ability to scale up to 1.23MWh, IP65 protection, integrated heating and built-in fire suppression, this system is engineered for reliable performance in demanding UK environments.
System Overview
Each 48.3kWh stack consists of:
• 3 × 16.1kWh LiFePO₄ battery modules
• Integrated top-mounted control unit
• Heavy-duty base plate structure
• Built-in 350A isolation breaker
Once assembled, the control unit manages all modules as one unified battery system — simplifying commissioning, inverter communication, monitoring and servicing.
The modular architecture allows additional stacks to be added at any time, making this solution ideal for phased commercial installs or growing energy demand.
