The Livoltek iPower HES-5000 All-in-One Energy Storage System is a wall-mounted, integrated solar storage solution that combines a 5 kW single-phase hybrid inverter with one to five LiFePO4 (LFP) battery modules in a single slim enclosure. Starting from 5.12 kWh and scalable to 25.6 kWh by stacking up to five BLF51-5 battery modules, this plug-and-play system is engineered for UK homes and small commercial premises seeking to maximise solar self-consumption, reduce grid dependency, and maintain critical backup power during outages — all without sacrificing wall space or aesthetics.
Built around a fanless, natural-cooling design, the iPower HES-5000 operates in near-silence, making it equally at home in a utility room or garage. A dedicated Wi-Fi/Bluetooth dongle comes included in the box, giving installers and homeowners immediate access to the My Livoltek cloud portal for real-time monitoring, scheduling, remote diagnostics and firmware updates — all at no extra cost.
25.6 kWh
Max. Storage (×5)
Installer Note: This system must be installed by a suitably qualified electrician. The inverter must be connected to a dedicated AC breaker on the grid side and the backup (EPS) side. The DC switch must be in the OFF position during all electrical connections. Do not connect the EPS output to the grid under any circumstances.
Battery Compatibility: The all-in-one system is designed exclusively for use with Livoltek BLF51-5 LiFePO4 battery modules. Connection of any third-party or incompatible battery will void the warranty. A maximum of five modules (25.6 kWh total) may be stacked per inverter. Parallel inverter operation is not supported in this bundle configuration.
Free Cloud Monitoring Included: Every system ships with a Wi-Fi/Bluetooth dual-function dongle. Connect to the My Livoltek app (iOS & Android) or web portal at evs.livoltek-portal.com for European & UK regions. Monitor generation, consumption, battery state, tariff scheduling and fault alerts — all at no ongoing subscription cost.
WHAT MAKES THE iPower HES-5000 STAND OUT
Fanless Natural Cooling
The iPower HES-5000 uses passive thermal management with no moving parts — eliminating fan noise, reducing wear, and extending the operational lifespan of internal components. Rated for continuous operation from –10°C to +55°C, it suits UK garages and utility rooms year-round.
150% PV Oversizing
With a max. PV input of 7,500 Wp against a 5 kW AC output, the inverter supports up to 150% PV oversizing. Dual MPPTs handle strings from different roof orientations simultaneously, capturing more energy during partial-shade periods and early-morning or late-afternoon sun angles typical in the UK.
Modular Battery Expansion
Start with a single 5.12 kWh BLF51-5 module and expand by stacking up to four additional units — reaching 25.6 kWh without rewiring the inverter. Each module has its own IP65 enclosure, 100 Ah nominal capacity, and a BMS communicating with the inverter via CAN bus for coordinated charge management.
Intelligent Cell Balancing
The built-in BMS performs active cell balancing and real-time temperature monitoring across all modules. This keeps cells at matched voltage levels throughout the charge cycle, maximising usable capacity and targeting over 6,000 charge cycles — equivalent to more than 16 years of daily cycling at 90% DoD.
Sub-10 ms EPS Backup
When a grid fault is detected, the system switches to Emergency Power Supply (EPS) mode in under 10 milliseconds — fast enough that most household appliances will not register the interruption. Backed-up loads connect via a dedicated EPS circuit output at 220 Vac / 50 Hz pure sine wave.
Time-of-Use & Export Control
Schedule battery charging and discharging by tariff period to take full advantage of Octopus Agile, Economy 7, or any multi-rate tariff. Pair with the CT sensor (included) and optional smart meter to enable precise zero-export / export-limited operation — essential for DNO compliance in many UK installations.
Compact Wall-Mount Design
The entire unit — inverter and battery modules — mounts on a single bracket assembly supplied in the box. Finished dimensions with one battery module are 415 × 1,380 × 165 mm, requiring as little as 300 mm clearance on all sides. A slim 165 mm depth keeps it flush to the wall in tight spaces.
Pure Sine Wave Output
Both on-grid and EPS outputs deliver a pure sinusoidal waveform with THDi below 3% under rated load — safe for sensitive electronics, variable-speed motors, and medical equipment. Power factor is adjustable from 0.8 leading to 0.8 lagging, providing compatibility with a wide range of UK load profiles.

FREQUENTLY ASKED QUESTIONS
Can I add more battery modules after initial installation?
Yes. The iPower HES-5000 supports up to five BLF51-5 battery modules, and additional modules can be retrofitted at any time. Each module simply stacks onto the existing bracket assembly and is connected via the battery power and BMS CAN cables. No changes to the inverter wiring or settings are required beyond updating the battery capacity configuration in the app.
Does the system work during a grid power cut?
Yes — provided the battery has sufficient charge. The EPS (Emergency Power Supply) function switches in under 10 milliseconds of detecting a grid fault, powering any loads connected to the dedicated EPS output circuit. The 5 kW EPS capacity handles most household appliances. Note that the EPS output must be on a separate circuit from the grid connection; your installer will configure this during commissioning.
Is the system compatible with smart export tariffs and DNO export limits?
Yes. The system includes a CT sensor that monitors grid import/export in real time. Through the My Livoltek app you can set a precise export limit (including zero export) to comply with Distribution Network Operator requirements or maximise Smart Export Guarantee income. Time-of-Use scheduling lets you define up to multiple charge/discharge windows per day to align with tariff periods such as Octopus Agile.
What cable sizes are required for installation?
The Quick Installation Guide specifies: AC cables 4 mm² – 6 mm²; PV cables 4 mm² – 6 mm²; battery power cables 25 mm²; PE (earth) cable 4 mm² – 6 mm². All cable sizing must be confirmed by the installing electrician against local BS 7671 wiring regulations and actual installation conditions. Expansion bolts require holes drilled to a minimum depth of 70 mm.
How does cloud monitoring work and is there a subscription fee?
The included Wi-Fi/Bluetooth dual-function dongle connects to your home router and registers the system on the Livoltek cloud portal (evs.livoltek-portal.com for UK/Europe). The My Livoltek app (available free on iOS and Android) provides real-time generation, consumption, battery state-of-charge, fault alerts, firmware updates and scheduling. There is no ongoing subscription charge. Remote diagnostics are also available to installers via the same portal.
What is the expected battery lifespan and warranty coverage?
Livoltek rates the BLF51-5 LFP battery modules at over 6,000 charge cycles at 90% depth of discharge — equivalent to over 16 years at one cycle per day. The system comes with a 10-year warranty covering both the inverter and battery modules. LiFePO4 chemistry is inherently thermally stable and does not suffer the capacity fade seen in NMC cells, making it the preferred choice for residential long-term storage.
