Off-Grid 10 kW System

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 12,000 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 12,000 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.
