Off-Grid 8 kW System

Off-grid
Single-phase

Complete 8 kW off-grid solar kit for homes with no grid connection: Growatt SPE 8000 inverter, 16 Tensite 500 W TOPCon panels and a HOPE 5 kWh lithium battery (expandable). Around 13,200 kWh per year, professional installation included.

Ideal for a consumption of ~240–640 kWh/month.

Payback values the usable energy (~40%) against the cost of running a diesel generator, with ~4% average annual diesel price growth. Unusable surplus is lost — off-grid there’s no grid to export to.

8 kW off-grid solar kit: production and autonomy

A 8 kW off-grid solar kit produces about 13,200 kWh of electricity a year — enough to power a home or finca with no mains connection. Supplied turnkey from €7,752, with panels, inverter, charge control and mounting sized to work as a standalone system.

With about 13,200 kWh a year, a 8 kW off-grid kit can run lighting, a fridge, pumps and everyday appliances without a grid connection. Pairing it with battery storage gives night-time and cloudy-day autonomy; the value here is independence from the mains and from a diesel generator, not a grid-bill saving.

The turnkey price has no hidden extras: it covers the solar panels, inverter, mounting structure and installation, the technical documentation, and the legalisation with the town hall and the electricity company — including the switch to a self-consumption contract. We hand it over working and registered, with no paperwork for you to chase.

A 8 kW kit suits a home using roughly 240–640 kWh per month. If your supply is three-phase, ask about the three-phase version; if your goal is full independence from the grid, look at the off-grid kits. The system can be expanded later with lithium battery storage.

About this product

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 13,200 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 13,200 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.

Frequently Asked Questions

How much does a 8 kW solar kit cost installed?

From €7,752, turnkey — panels, inverter, mounting, installation and the legalisation and contract change are all included. You get a closed price up front, with no surprises on the day of installation.

How much electricity does a 8 kW system produce?

About 13,200 kWh per year in Spain, depending on roof orientation, tilt and shading. That is the figure used for the production and savings shown on this page.

Can an 8 kW off-grid kit power a whole house?

Yes, for a medium home with efficient appliances. It produces around 13,200 kWh per year and the included battery stores energy for the evening. For heavy or simultaneous loads we recommend expanding the battery bank.

How much battery storage do I need for off-grid?

It depends on your daily consumption and how many days of autonomy you want. The kit ships with a 5 kWh battery as a base; you can expand the HOPE bank up to 45 kWh from the add-on selector to cover cloudy days and winter.

What happens on cloudy days or in winter?

Off-grid systems are sized for the month with the least sun. We recommend expanding the battery and, for long spells of bad weather, keeping a backup generator — the SPE inverter has a generator input. Our team sizes it for your location.

Do I need a grid connection for this kit?

No. This is a standalone (off-grid) system designed for properties with no connection to the electricity grid — country houses, fincas and remote homes.

Can I expand the system later?

Yes. You can add battery modules at any time, and the SPE inverter supports a generator input for extra peace of mind.

Is installation included in the price?

Yes. The price is closed and includes professional installation, wiring, protections and commissioning across Spain.
