The Solis IntelliHome range is Solis's newest low-voltage residential storage platform — a modular family of LiFePO4 (lithium iron phosphate) batteries in three module sizes, engineered to pair directly with Solis's proven S5 and S6 single-phase hybrid inverters. Whether the customer is a first-time solar owner adding 5 kWh of night-time cover to a small terrace or a self-builder specifying 40 kWh with heat-pump and EV integration, IntelliHome scales the same building blocks across the whole spec sheet.

For UK homeowners and MCS-accredited installers, the appeal is straightforward: LiFePO4 chemistry, an IP66 outdoor and C5-M anti-corrosion rating for coastal and unheated garage installs, integrated battery heating down to −20°C, and full compatibility with the same Solis hybrid inverters already installed across tens of thousands of UK homes. The full range is available now via our Solis brand page and Storage Batteries collection.

IntelliHome is engineered around a simple principle: modular stacking, capacity on demand — the same building block scales from 5 kWh in a starter apartment to a 128 kWh energy hub for a rural estate. — Solis product positioning, SolisStorage IntelliHome platform overview

What makes IntelliHome different

The IntelliHome design brief centred on three pain points that dominate real-world UK storage installs: safety (particularly for garage and outdoor wall-mounts), cycle life under time-of-use charging, and honest scaling to household demand that grows over time (heat pump, then EV, then EV number two). Here's how the platform addresses each.

1

Grade-A LiFePO4 cells, 100% DoD

A+ grade cells rated for over 6,000 cycles at 100% depth of discharge, with a 10-year performance warranty. Internal resistance of around 0.26 mΩ and a tight 0.1 mΩ batch range keeps parallel-string balancing precise.

2

IP66 & C5-M anti-corrosion

Full outdoor rating (IP66) plus C5-M coastal corrosion resistance means IntelliHome installs happily on an exterior wall, in an unheated garage, or in a coastal property without the ambient-temperature caveats that limit older LV batteries.

3

Built-in heating to −20°C

An integrated heating element allows safe charging in ambient temperatures down to −20°C — critical for UK properties with outdoor or garage-mounted batteries where winter mornings can drop well below LiFePO4's usual charging floor.

4

1C discharge for price arbitrage

Full 1C continuous discharge (i.e. a 10 kWh module delivers up to 10 kW) means IntelliHome can genuinely support Octopus Agile or Cosy peak-window loads — kettle, oven, heat pump — without derating during the highest-price hours.

5

Solis AI energy management

The SolisCloud platform layers forecasting, TOU tariff optimisation, heat-pump surplus channelling, and smart EV charging on top of the hardware — the kind of intelligence that turns raw storage into real bill savings.

6

Sub-10 ms grid switching

Backup switchover in under 10 ms — fast enough that routers, NAS drives, computers, and modern boilers stay online through a grid drop without a reboot cycle.

7

Independent module operation

Each module runs independently with natural charge balancing — a failure in one 5, 10 or 16 kWh block won't bring down an entire parallel string, unlike older master-slave BMS architectures.

8

Stackable to 128 kWh per string

Parallel up to 8 modules per string, mix and match capacities, and expand as household demand grows — heat pump this year, EV next, second EV the year after — without ripping and replacing.

5-star safety architecture

Because a home battery lives on the same wall as your family, IntelliHome's safety stack is deliberately over-engineered.

Explosion release valves on each pack for controlled thermal event venting
DC overcurrent isolator and dedicated DC fuses on every module
Pack-integrated aerosol fire suppression, activated automatically
Aerogel thermal insulation between cells slows propagation
51.2 V 1P16S low-voltage design — no arc-discharge, no shock risk
Dual-soldering cell inspection, 99.999% yield at manufacture

Sizing IntelliHome to the property

Solis positions IntelliHome across four residential archetypes. These are the typical starting configurations — each is a real product bundle we can quote at a system level, mixing the appropriate battery module count with the correct S5 or S6 hybrid inverter.

5 kW / 10 kWh

City apartment or small terrace

One 10 kWh module paired with a 3–6 kW single-phase hybrid inverter. Covers overnight base load, morning kettle-and-shower peak, and a full evening cook cycle on off-peak stored energy.

12 kW / 25 kWh

Medium 3–4 bed home

Two 10 kWh modules plus a 5 kWh, matched with a 6–12 kW hybrid inverter. Enough capacity to fully cover a typical family's day-and-night electricity draw with 4–6 kW of solar.

18 kW / 40 kWh

Large home with heat pump & EV

Two 16 kWh modules plus a 10 kWh, on a 15–18 kW hybrid inverter. Sized to run a heat pump through a winter evening while simultaneously charging an EV overnight on Octopus Go.

2 × 18 kW / 160 kWh

Rural estate or light commercial

Two parallel 18 kW inverters running eight 16 kWh modules across two strings — for large properties, community energy hubs, or small workshops on a single-phase spur.

Model comparison at a glance

All three IntelliHome modules share the same core chemistry, safety, and comms platform — the choice is fundamentally about capacity, weight, and how many modules the wall can carry.

Matched Solis hybrid inverters

IntelliHome is designed for direct integration with the current Solis low-voltage hybrid range — the S5-EH1P and S6-EH1P families. These are the single-phase inverters that dominate current UK residential retrofit and new-build storage installs, and they carry the correct G98/G99 certifications and MCS approvals. The batteries are also compatible with wider S5-EH, S6-EH, S6-EO and S5-EA storage-and-off-grid variants across the same 44.8–57.6 V window; the four models below are the ones we most commonly bundle with IntelliHome for standard UK single-phase homes.

Which inverter? A quick rule of thumb: 3–3.6 kW suits an apartment or small terrace running one 5–10 kWh module; 6 kW is the sweet spot for a typical 4-bed family home with 4–6 kW of PV and one or two batteries. For heat-pump and EV households, or three-phase, see the extended range on our Hybrid Inverters collection.

Why Solis is one of the UK's most-installed inverter brands

Solis (the storage and inverter arm of Ginlong Technologies) sits consistently in the top three global inverter shipment tables, and has been present in the UK for over 15 years. For anyone specifying an IntelliHome system, that ecosystem strength matters in five practical ways:

G98 & G99 across the range

The S5 and S6 hybrid families carry current G98 (up to 16 A per phase, notify-after) and G99 (larger, DNO-accepted) certifications, meaning the DNO paperwork is a known quantity for MCS installers rather than a bespoke engineering exercise.

MCS-installable systems

A Solis + IntelliHome install can be registered under the MCS scheme by any accredited installer, which is the gateway to zero-VAT eligibility on qualifying domestic installs and to the Smart Export Guarantee (SEG) tariffs.

Wide battery compatibility

Even outside the IntelliHome range, Solis inverters have long approved-battery lists covering Pylontech, BYD, Dyness and Weco — useful for retrofits where a legacy battery already exists and only the inverter is being upgraded.

SolisCloud & TOU tariffs

The SolisCloud platform integrates cleanly with UK time-of-use tariffs (Octopus Agile, Cosy, Go, Flux) — 6-stage TOU scheduling on the S6 PLUS series means charging shifts to overnight low-price windows without third-party controllers.

Installer familiarity & parts

The UK installer base has years of Solis experience, and spares (comms sticks, meters, fuses) are stocked domestically. Diagnostic tools, firmware and support English-language documentation are all mature.

Strong warranty backing

Standard 5-year inverter warranties (extendable to 10–20 years) and 10-year battery performance warranties on IntelliHome, aligned with MCS PAS 63100 expectations for domestic battery installs.

G98 / G99 MCS-installable IEC 62619 CE / UKCA IP66 C5-M SEG-eligible
