Off-Grid 10 kW System
Complete 10 kW off-grid solar kit for larger homes and fincas with no grid connection: Growatt SPE 10000 inverter, 20 Tensite 500 W TOPCon panels and a HOPE 5 kWh lithium battery (expandable). Around 16,500 kWh per year, installation included.
Ideal for a consumption of ~300–800 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.

10 kW off-grid solar kit: production and autonomy
A 10 kW off-grid solar kit produces about 16,500 kWh of electricity a year — enough to power a home or finca with no mains connection. Supplied turnkey from €9,012, with panels, inverter, charge control and mounting sized to work as a standalone system.
With about 16,500 kWh a year, a 10 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 10 kW kit suits a home using roughly 300–800 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
10 kW off-grid solar kit: energy independence with no grid connection
This 10 kW off-grid solar kit is designed for larger rural homes and working fincas that need to run more at once and stay completely independent from the grid. Its 20-panel array and Growatt SPE off-grid inverter generate around 16,500 kWh of clean energy a year — enough headroom for water pumps, several appliances and a comfortable home, with lithium storage for the night.
Growatt SPE 10000 ES off-grid inverter
The Growatt SPE 10000 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.
20 Tensite 500 W TOPCon N-Type panels
The 10 kW array is built from 20 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 16,500 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 10 kW off-grid kit for?
It suits larger off-grid households and small fincas: a full family home with a fridge-freezer, washing machine, water pumps, a workshop or outbuildings, and the occasional heavier load. It gives you more daily production and surge capacity than the 8 kW kit; for the most demanding properties, see the 12 kW kit.
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 10 kW solar kit cost installed?
From €9,012, 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 10 kW system produce?
About 16,500 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.
What can a 10 kW off-grid kit run?
A larger home or finca: fridge-freezer, washing machine, lighting, electronics, water pumps and the occasional heavier appliance. It produces around 16,500 kWh a year; for continuous heavy loads we recommend expanding the battery bank.
How many days of autonomy will I get?
Autonomy depends on the battery size versus your daily consumption. The kit includes a 5 kWh battery as a base; expand the HOPE bank up to 45 kWh from the add-on selector to add days of backup for cloudy spells.
Can it run a water pump or workshop?
Yes. The SPE off-grid inverter is designed to absorb the start-up surge of pumps and motors. For frequent or simultaneous heavy use, we will help you size the array and battery accordingly.
Do I need a grid connection?
No. It is a standalone off-grid system for properties without a connection to the electricity grid.
Can I add a generator as backup?
Yes. The Growatt SPE inverter has a generator input, useful for long spells of bad weather on top of expanded battery storage.
Is installation included?
Yes. The closed price includes professional installation, wiring, protections and commissioning across Spain.
