Off‑grid Hybrid Energy Storage System The Off‑grid Hybrid Energy Storage System (Off‑grid Hybrid ESS) is a straightforward way to boost your energy independence. It includes a Sunsynk ECCO 5kW Off‑grid Hybrid Inverter, 2× Fogstar Drift 24V 300Ah Gen 2 Lithium Battery Modules, and 14× PHONO Meteor 450W Mono MC4 Panels (custom quantities of solar panels and batteries are available on request), plus an optional Excel Power XL6000i‑DF 6kW Dual‑Fuel Inverter Generator. A basic set of cables is included to make installation easier. Solar panels, mounted on the roof or on the ground, capture sunlight and generate direct current to charge the battery. The hybrid inverter then converts that stored energy into alternating current for use in homes or small businesses. The Off‑grid Hybrid ESS manages any surplus energy by storing it in the battery or, where allowed, feeding it into the grid. Home energy storage lets you use the electricity you generate when you need it most. The battery bank stores renewable energy from solar photovoltaic (PV) panels or a wind turbine. For example, power generated during the day can be stored and used in the evening for tasks such as boiling the kettle or running electronic devices. You can tailor the Off‑grid Hybrid ESS to your situation, taking into account your current energy use, the size of any existing generation equipment, and future plans such as getting an electric vehicle (EV) or installing a heat pump for heating. The system must be installed by a licensed electrician or technician in compliance with all applicable regulations and guidance. For residential properties, guidance here must be followed.

It suits both on‑grid and off‑grid storage setups. SUNSYNK ECCO 5.0kW Off‑grid/Hybrid Inverter delivers 5.0kW in on‑grid mode and back‑up power in off‑grid mode, with 24‑hour energy management and real‑time monitoring of your PV system. SUNSYNK ECCO 5.0kW Off‑grid/Hybrid Inverter – Uninterruptible power supply switches to the battery in less than 10ms if the grid fails. The inverter’s EMS function improves battery reliability, and remote control and software updates let you manage the system digitally. FOGSTAR DRIFT 24V 300Ah Gen 2 7.2kWh LV LFP Battery is rated for more than 4500 cycles at 80% depth of discharge. Two modules in series give 14.4kWh of usable storage, with around 98% charge/discharge efficiency and plug‑and‑play installation. PHONO Meteor 450W Black Frame MC4 Solar Panel captures up to 6.3kW DC and converts it to AC for immediate use in the home or business, with surplus energy stored in the battery or, where allowed, fed into the grid. Durable, dust‑ and water‑resistant solar panels – The PHONO 450W panel is dust‑ and water‑resistant so it can cope with most weather. An anti‑reflective and anti‑soiling surface helps reduce power loss from dirt and dust. It comes with a 15‑year product warranty and a 30‑year linear power‑output warranty. Delivery – 4–5 working days within the UK (longer to the Highlands, islands and Northern Ireland). ▼ Off‑grid Hybrid ESS specifications PHONO Meteor 450W Mono Black Frame MC4 Solar Panel Rated (peak) power (Wp): 450W at 1000 W/m² Open‑circuit voltage (Voc): 35.74 V Voltage at maximum power (Vmp): 30.1 V Short‑circuit current (Isc): 15.64 A Current at maximum power (Imp): 14.95 A Efficiency: 22.5% Cell type: Monocrystalline silicon Connector type: MC4 Certification: IEC 61215 / IEC 61730 / IEC TS 63209 / IEC TS 63342 / TÜV Rheinland Net weight: 13.7 kg Size: 1762 × 1134 × 30 mm FOGSTAR DRIFT 24V 300Ah Gen 2 Lithium Battery Battery type: LiFePO₄ Nominal capacity: 7.2 kWh Nominal voltage: 25.6 V Max. charge/discharge current: 300 A / 300 A Depth of discharge: 80% Cycle life: >4500 cycles at 25°C, 80% DOD Installation location: Indoor or outdoor Operating temperature range: Charge −20°C to +55°C (with heating); discharge −20°C to +55°C Ingress protection: IP67 Net weight: 60.6 kg Size (L × W × H): 698 x 205 x 280 mm SUNSYNK 5kW SUN‑5K‑SG04LP1 Off‑grid/Hybrid Inverter Solar input Max. solar power (Wp): 6.5 kW Max.
