Description
This package pairs a Solis 5kW AC-coupled hybrid inverter with a Fogstar Energy ECO 16.1kWh lithium battery, professionally installed at your property. AC coupling means the system bolts onto your existing solar PV setup without ripping out your current inverter, so it is the cleanest way to add storage to a working solar system. It is equally happy as a standalone battery for time-of-use tariff arbitrage if you don’t have panels yet.
What you get with this package:
- Solis 5kW AC-coupled hybrid inverter
- Fogstar Energy ECO 16.1kWh battery system
- AI-driven optimisation to charge from cheap-rate electricity (Octopus Go, Intelligent, Cosy, Agile, etc.) and discharge during peak hours
- Full design, supply and installation by our MCS-accredited engineers
- DNO application and G99 / G98 paperwork handled for you
- All cabling, isolators, mounting and commissioning included
- Handover walk-through and app setup on the day
- Installation anywhere in the Midlands included in the price
Why people choose this kit:
- 16.1kWh of usable storage is enough to cover an average UK home’s overnight and evening load comfortably, with headroom for an EV top-up or a heat pump’s shoulder hours.
- AC coupling keeps your existing solar inverter in place, so no warranty headaches and no re-commissioning of your panels.
- AI optimisation means the system learns your usage and your tariff, so it stops being something you have to think about after week one.
- Lithium iron phosphate (LFP) chemistry in the Fogstar ECO is safer and longer-cycling than older NMC packs.
What’s included in the install:
- Site survey and electrical assessment
- Wall or floor mounting of the battery and inverter
- AC and comms wiring to your consumer unit
- CT clamp / metering for grid-flow monitoring
- System commissioning and app pairing
- Customer handover and aftercare contact
Coverage: Midlands installation included.
