Off-Grid 12 kW System

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

This 12 kW off-grid solar kit is our largest standalone system, built for big villas and fincas that want total energy independence with no grid connection. With a 24-panel array and the powerful Growatt SPE off-grid inverter, it produces around 14,400 kWh of clean energy a year and feeds a lithium battery bank, so even a demanding property runs comfortably day and night on solar alone.

Growatt SPE 12000 ES off-grid inverter

The Growatt SPE 12000 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.

24 Tensite 500 W TOPCon N-Type panels

The 12 kW array is built from 24 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 14,400 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 12 kW off-grid kit for?

It’s made for large off-grid homes, villas and fincas with high demand: multiple bedrooms and bathrooms, fridge-freezers, washing and drying, water pumps, outbuildings or a workshop, and several loads running at the same time. Paired with an expanded HOPE battery bank, it delivers full, comfortable energy independence.

Professional installation included across Spain
