High in the olive hills above Loja stands a finca where the grid was never a comfortable option. The owners wanted to run the house on their own sun: lights, water pumps, kitchen, air conditioning and the deep well, day and night, without a generator rumbling in the background.
We started with the ground, literally: levelling the terrace, digging the footings and pouring concrete foundations for a galvanised frame that carries 28 Aiko 610 W panels at the perfect angle, clear of the olive trees. From there an 80-metre cable run reaches the technical area, where a 15 kW single-phase Deye hybrid inverter works together with 32 kWh of our own MTS battery storage.
The part the owners notice most is invisible: the ATS and EPS. If anything drops out, the system switches over by itself and the house simply keeps running — the fridge never blinks. The installation was built for this specific finca, with the option to grow the battery bank further as they move towards being fully self-sufficient.
Price range for a project of this scope, including groundworks, concrete, frame, panels, battery, inverter, 80 m cable run, ATS, EPS, materials and installation: 27.500 € – 32.500 €. At the customer's request we name the location only, not their name.
