Engineered for Reliability and Performance Solis combines MPPT, PCS, grid-tied/off-grid switching (STS), and EMS into one unified control system, which is pre-integrated and tested at the factory to enhance reliability.
As standard the C5 battery cabinet includes the following layers of protection:
- Cell - pressure release valve
- Pack - all round temperature monitoring, aerosol fire suppression on pack level, insulation and heat isolation layers
- Cabinet - thermal detection, smoke detection, water immersion sensor, humidity detection, and aerosol fire suppression on cabinet level
Key system features:
- Switches between on- and off-grid in under 10 ms, ensuring uninterrupted operation for critical loads.
- Scalable up to 6 systems for 750 kW / 1.56 MWh to meet expanding energy demands.*
- High-capacity 314 Ah LFP cells with multi-layer protection deliver long-term safety and reliability.
- Patented air-cooling design maintains stable thermal performance without liquid coolant.
- Supports up to 2× PV oversizing and 21 A string input, maximising solar yield.
- Delivers 160% overload for 200 ms in off-grid mode for stable heavy-load startup.
- SolisCloud enables smart monitoring, AI control, and remote updates.
- IP55 rated battery cabinet and IP66 rated inverter.
- 8000-cycles at 75% DoD with 70% energy retention after cycle life.
- 10-year warranty
*A maximum of 6 systems can be parallelled (6-inverters or 6-battery cabinets).
The system wil allow 10-inverters only to be paralleled post the release of the Solis Power Distribution Cabinet.
