Off-Grid 8 kW System

8 kW off-grid solar kit: energy independence with no grid connection

This complete 8 kW off-grid solar kit is built for homes with no connection to the electricity grid — country houses, rural properties and small fincas. With 16 high-efficiency panels, a Growatt SPE off-grid inverter and a lithium battery, it produces around 9,600 kWh of clean energy a year and stores it so you have power day and night, fully independent from any utility.

Growatt SPE 8000 ES off-grid inverter

The Growatt SPE 8000 ES is a dedicated off-grid (island) inverter with built-in MPPT charge control. It manages the solar array, the battery and your home’s loads in a single unit, delivering a stable 230 V supply and absorbing the start-up surges of pumps, fridges and motors. It also accepts a backup generator input, so you keep power even through long spells of bad weather.

16 Tensite 500 W TOPCon N-Type panels

The 8 kW array is built from 16 Tensite 500 W solar panels with TOPCon N-Type cells: high efficiency, strong output in diffuse light and at high temperatures, and long-term durability — your system keeps producing reliably for decades. Altogether it generates around 9,600 kWh of clean energy per year.

Lithium storage, expandable to your needs

The kit includes a HOPE 5 kWh LiFePO4 battery as a base. Off-grid storage should match your real daily consumption and the days of autonomy you want, so the HOPE bank is modular and expandable up to 45 kWh — add capacity now or grow it later from the add-on selector. LiFePO4 chemistry gives you a deep usable capacity and a long cycle life.

Who is the 8 kW off-grid kit for?

It’s ideal for a medium off-grid home: a couple or a family in a country house or finca with efficient appliances, lighting, a fridge, a water pump and everyday electronics. If you run heavy or simultaneous loads, look at the 10 kW or 12 kW off-grid kits — or simply expand the battery bank.

Professional installation included across Spain

The price is closed, with no surprises: it includes professional installation, the mounting structure, wiring and protections, battery commissioning and system start-up. Our team designs and sizes the installation for your location and your consumption, and takes care of all the paperwork.
