Solis Commercial Battery Storage Cabinet with Hybrid Inverter

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.

Protection: what both cabinet grades share

• Cell – pressure release valve
• Pack – all round temperature monitoring, insulation and heat isolation layers
• Cabinet – thermal detection, smoke detection, water immersion sensor, humidity detection

What the C5 PRO adds – choose PRO where the site, the insurer or the DNO asks for active fire protection:

• Aerosol fire suppression, at pack and cabinet level
• Flammable gas detector
• Audible and visual alarms
• Explosion relief panel
• Enhanced corrosion coating for harsh environments – high salt exposure, extreme humidity or heavy pollution

The standard C5 has none of the items in that second list. It is the right choice for a sheltered indoor or low-corrosion site where active fire suppression is not a requirement.

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 300 kW / 600 kWh 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.
