Description
This is a flexible hybrid storage package designed for homes that need real headroom: heavy evening loads, EV charging, heat pumps, or anyone planning to add more PV later. The Solis PLUS S6 hybrid inverter is available in 3.6kW, 5kW, 6kW, 8kW or 10kW, and pairs with one or more Fogstar Energy 16.1kWh ECO batteries, scalable up to 64.4kWh on a single inverter.
Hybrid means the inverter handles your solar PV, battery, grid and backup loads in one unit. If you have existing panels, the same inverter can AC-couple to them so nothing already installed needs ripping out.
Solis PLUS S6 Hybrid Inverter, key features:
- Single-phase low-voltage hybrid, sized 3.6kW to 10kW
- 8 MPPTs for flexible solar string design
- Up to 190A maximum charge / discharge current for high-power battery performance
- Up to 200% DC oversizing for greater solar harvest
- 200% surge power capability for 10 seconds to handle high inrush loads
- Integrated backup port with automatic UPS-level switching for power-cut continuity
- Six fully customisable charge / discharge time slots for tariff optimisation
- AI-optimised cloud-based energy management assistant
- Generator connectivity with automatic start / stop control
- Parallel operation up to 48kW, single or three-phase
- Intelligent AC-coupling for retrofitting to existing solar systems
- Peak shaving in both self-use and generator modes
- Compatible with lithium and lead-acid battery chemistries
Fogstar Energy 48V 16.1kWh ECO Battery (2026 Edition), key features:

Why people choose this kit:
- Up to 64.4kWh of usable storage on a single inverter, so the system grows with your needs.
- Hybrid architecture handles solar, battery, grid and backup in one box, fewer points of failure than separate inverter + battery setups.
- AI optimisation learns your usage and your tariff so the system runs itself after the first week.
- Fire suppression and -10°C charging come as standard on the 2026 Fogstar ECO, peace of mind for garage and outbuilding installs.
- Lithium iron phosphate (LFP) chemistry is safer and longer-cycling than older NMC packs.
- 200% DC oversizing means you can install more solar than the inverter rating, capturing more energy on cloudy days without losing peak-day generation.
What’s included in the install:
- Site survey and electrical assessment
- Wall or floor mounting of the battery and inverter
- AC, DC and comms wiring to your consumer unit
- CT clamp and grid metering for live energy monitoring
- System commissioning and app pairing
- Customer handover and aftercare contact
Coverage: Midlands installation included in the price.
