Off-grid Hybrid Energy Storage System with SUNSYNK MAX 16kW 48V Inverter, Dyness 30.7kWh LFP Battery, and (optionally) 15.48kW Solar Panels and Senci 12kW Petrol Inverter Generator
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
- Sunsynk MAX 16kW 48V Single Phase Off-grid Hybrid Inveter with WiFi, 3x Dyness PowerBox G2 10.24kWh Lithium Battery, (Optional) 33× DMEGC 515W Bifacial Double Glass All Black Solar Panels (custom quantities of solar panels and batteries are available on request), and Senci SC15000i 12W Petrol 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.

- SUNSYNK MAX 16kW 48V SINGLE PHASE INVERTER with WIFI included combines a solar inverter and a battery inverter in one unit, so it can manage power from your solar panels, battery, and the grid at the same time. It suits both on‑grid and off‑grid storage setups.
- SUNSYNK MAX 16kW 48V SINGLE PHASE INVERTER delivers 16.0kW in on‑grid mode and 13.0kW back‑up power in off‑grid mode, with 24‑hour energy management and real‑time monitoring of your PV system.
- SUNSYNK MAX 16kW 48V SINGLE PHASE 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.
- DYNESS PowerBox G2 10.24 kWh LV LFP Battery is rated for more than 6000 cycles at 80% depth of discharge. Three modules in parallel give 30.7kWh of usable storage, with around 98% charge/discharge efficiency and plug‑and‑play installation.
- DMEGC 515W N-Type Bifacial All Black Solar Panels captures up to 17kW 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 DMEGC 515W 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 25‑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).
