What on & off-grid with Solarfit involves

Grid-tied, off-grid or a hybrid middle way — which inverter fits depends on your situation.

The choice

On the grid, or completely off it

The inverter is the heart of your system — it decides whether you're tied to the grid or standing free of it. Grid-tied, you feed your surplus back and get the fastest payback. Off-grid — batteries and an off-grid inverter — makes you fully self-sufficient, ideal in the campo where a grid connection soon runs to 10,000 to 15,000 euros; off-grid is often about the same price or cheaper there, and the grid bill is gone for good. If you want the security of the grid and your own storage, a hybrid inverter is the middle way — the grid as backup, with a smaller battery.

  • Grid-tied — feed your surplus back, fastest payback
  • Off-grid — batteries + off-grid inverter, fully self-sufficient
  • Hybrid — the grid as backup, with a smaller battery
  • Legally registered with Industria, so insurance and resale are in order

How we do on & off-grid

On and off-grid is the configuration of your solar system — the sizing is exacting, so we work it all out up front in software. If we installed your system, we already know it; otherwise a technician visits before installation.

Call us and we'll pick up your enquiry straight away; enquire online and we'll ring you back — always in English.

Frequently asked questions

The questions we're asked most about on and off-grid.

What's the difference between grid-tied (hybrid) and off-grid — and what do I need?

Grid-tied (hybrid) you stay connected to the grid — you use your own solar power, store surplus in a battery for the evening, and the grid is your backstop. Off-grid you're fully self-sufficient, with no grid connection at all, ideal for a finca in the campo where a connection is expensive or impossible. If you already have a grid connection, hybrid is usually smartest; if you're out in a remote spot, off-grid is often cheaper.

What if the sun doesn't shine for a few days with an off-grid system?

Then you run on your batteries — we size those to your consumption, with enough reserve to ride out cloudy days. On the Costa Blanca the sun shines for a large part of the year, so in practice you're rarely left without.

Will my power keep working if the grid goes down?

Yes — that's exactly the advantage of this system. With a hybrid or off-grid setup with a backup function, your home switches over to your battery automatically in an outage, and you simply carry on. That's the difference from ordinary grid-tied panels, which shut off in a cut.

What's in an on or off-grid system?

More than just panels — the solar panels, a hybrid or off-grid inverter, and the batteries that store your solar power. With off-grid you add the control gear that runs it all. We supply and install it as one matched whole.
