Description
This package pairs the Solis 8kW or 10kW PLUS single-phase hybrid inverter with the Fogstar Energy modular battery stack, a single integrated battery system of 3 or 4 stacked 16.1kWh modules managed by one top-mounted control unit. Compared with multiple standalone batteries, the modular stack simplifies commissioning, inverter comms and servicing because the inverter sees the whole stack as one battery.
The stack is IP65 rated for indoor, plant room or outdoor installation, has a built-in 350A isolation breaker, integrated heat-activated fire suppression, and self-heating that allows safe charging down to -15°C. That makes it a sensible choice for larger residential systems, workshops, agricultural sites, and small commercial properties where space, safety and serviceability all matter.
Solis PLUS S6 Hybrid Inverter, key features:
- Single-phase low-voltage hybrid, 8kW or 10kW
- 8 MPPTs for flexible solar string design
- Up to 190A maximum charge / discharge current
- 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

Why people choose this kit:
- From 48.3kWh up to 128.8kWh of usable storage on a single inverter, ideal for larger residential systems, agricultural sites, workshops and small commercial buildings.
- One integrated battery instead of three or four loose units: cleaner installation, simpler comms, less to maintain.
- IP65 rating means the stack can mount outside on a wall or in an unheated plant room, freeing up indoor space.
- Built-in 350A breaker gives proper isolation for service work without separate external switchgear.
- Fire suppression and -15°C self-heating come as standard, useful for UK winter installs in unheated locations.
- AI optimisation learns your usage and your tariff so the system runs itself after the first week.
- Lithium iron phosphate (LFP) chemistry is safer and longer-cycling than older NMC packs.
- 6-year manufacturer warranty plus 10 years of UK-based support on the battery.
What’s included in the install:
- Site survey and electrical assessment
- Wall or floor mounting of the inverter and battery stack
- 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.
