100kWh Battery Storage — Alhaurín el Grande
This is our flagship 100kWh DEYE battery installation Málaga province has seen — a large-scale energy storage project for a rural finca in Alhaurín el Grande, completed by LIT Electricians in March 2026. As a specialist in battery storage Málaga and the wider Costa del Sol, this project represents the most ambitious home battery backup Spain has seen at residential scale. The 20× DEYE 5kWh LiFePO4 modules housed in two rack towers make it the defining example of large scale home battery storage Costa del Sol clients can reference. The DEYE LiFePO4 battery Spain specification was chosen for its 6,000-cycle lifespan at 80% depth-of-discharge — over 16 years of daily cycling before reaching 80% capacity retention. As a battery storage finca Spain installation, the scale matches the finca's demands: three-phase pool pump, air conditioning, water heating, irrigation, and full household loads all run from stored solar energy. As the premier example of solar battery storage rural Andalucia 2025 and 2026, this energy storage system Alhaurín el Grande delivers 95% energy self-sufficiency year-round, drawing from the grid only during extended overcast spells. The DEYE battery Málaga infrastructure pairs with a 54kWp solar PV array generating 98,000 kWh annually — making this the standout case study for solar battery storage inland Málaga and for anyone evaluating an off-grid battery system Andalucia for a finca or cortijo. The full LiFePO4 battery storage system is monitored via DEYE SolarmanPV, with 80kWh net daily discharge capacity (80% DoD) providing genuine energy independence 365 days a year. For property owners comparing 100kWh battery storage Spain options — grid-tied with backup or fully off-grid — this installation demonstrates what is achievable with correct system sizing and professional installation by a certified installer in Málaga province.
Tesla Wall Connector Gen 3 — Private Garage, Estepona
This Tesla Wall Connector Estepona installation is the definitive case study for expat Tesla owners on the Costa del Sol seeking a certified, REBT-compliant home charging solution. LIT Electricians completed this Tesla Wall Connector Gen 3 installation in Estepona in March 2026 — a single-day job from consumer unit survey to app commissioning — and it now stands as the benchmark Tesla home charger installation Costa del Sol clients can reference when evaluating their options. The Tesla Wall Connector Gen 3 is the only home charger Tesla officially recommends for their vehicles: it delivers up to 11kW AC on three-phase supply, or up to 7.4kW on the single-phase supply standard across Spain. For this Tesla Model Y home charger Spain installation, the client's 32A single-phase supply delivers a reliable 7.4kW charge rate — 48km of Model Y range added per hour of charging, meaning an overnight 8-hour charge adds 384km of range from near-empty. At current Endesa electricity rates of approximately €0.18–0.22/kWh (off-peak), a full 75kWh charge costs €13.50–16.50 at home. The same charge at a Supercharger costs approximately €27–33, and at the slowest public AC chargers in Estepona, over 32 hours of connection time. The economic argument for a Tesla Wall Connector installer Málaga engagement is overwhelming — this installation pays for itself within 18 months of normal use. Beyond the economics, this installation delivered what the client actually wanted: a Tesla Wall Connector Gen 3 installation Spain that is future-ready. The Wall Connector supports Tesla's Power Sharing (up to 6 units sharing one circuit), WiFi connectivity for remote monitoring, over-the-air firmware updates, and full integration with the Tesla app for scheduled charging during off-peak electricity tariff windows. All works were completed to REBT ITC-BT-52 (Infrastructure for EV Charging) and signed off with a Boletín Eléctrico — the mandatory Spanish low-voltage electrical certificate required for any modification to a home's fixed electrical installation.
EV Charger Make-Ready — Calahonda Urbanisation
Complete EV charging infrastructure for a communal underground car park in a Calahonda urbanisation. Zaptec Pro charger with Toscano eco-VE protection, galvanised steel cable tray system running through the parking garage, and ITC-BT-52 compliant electrical distribution — designed so any resident can add their own EV charger quickly and affordably in the future.

6kW DEYE Solar — Benahavís Golf Community
Most of our Benahavís solar jobs are large standalone villas with a single owner making all the decisions. This one was different from the moment the client called. The property was a townhouse in one of the golf communities west of the village, and the roof belonged to the community — not the client. That changes everything about how a job gets started. The system itself is straightforward enough: 12 × 500W monocrystalline half-cut panels, two strings of six, feeding into a DEYE SUN-6K-SG03LP1-EU single-phase hybrid inverter. Six kilowatts on a south-facing terracotta tile roof, portrait-mounted in two clean rows. You can see from the photo exactly what we were working with — the forested hills behind, the terracotta rooftops of the neighbouring townhouses below, and the pine trees to the east that became part of the engineering conversation. Benahavís sits at around 200 metres above sea level, which gives it a slightly different microclimate from the coast. It's marginally more sheltered from the summer sea haze, but also occasionally mist-covered in winter mornings. PVGIS data for the site coordinates — 36.52°N, 5.04°W — puts the annual irradiance at around 1,750 kWh per kilowatt-peak. That's a touch lower than what you'd see on a south-facing Costa del Sol seafront, but still very good solar country. With 6kW of panels at that yield, we projected 10,500 kWh per year in generation. The household's annual consumption was running at around 15,400 kWh. So this system, with sensible usage habits and a bit of scheduling, offsets roughly 68% of their electricity. The maths works out to around €1,512 per year in savings — partly from avoided purchases at the retail rate, partly from surplus compensation paid by Endesa under the autoconsumo con compensación simplificada tariff. At a total installed cost in the €9,000–€10,500 range, we're looking at a payback of around 6.5 years on a system that should comfortably last 25. The DEYE SUN-6K-SG03LP1-EU was specified partly for its battery-ready architecture. The client wasn't committing to batteries yet, but they mentioned it — and once somebody's mentioned batteries, we'd rather put in a hybrid inverter now than replace a grid-tied inverter in two years' time.
Villa First Fix: 3-Phase & Airzone, Alhaurín
The client, an American expat based on the Costa del Sol, had bought an older villa in Alhaurín de la Torre with the intention of gutting it and doing it properly. Four bedrooms, approximately 200 square metres, a builder already appointed — and a clear brief: when this renovation is finished, the house should work the way a modern European home should work. Comfortable temperatures year-round, enough electrical capacity for anything the family might want to add, and nothing that creates problems to fix later. First fix is the stage of any renovation that nobody photographs, few homeowners fully understand, and almost every builder underestimates. It is the window — usually measured in days, not weeks — when the walls are open and the ceilings are bare, before the plasterers arrive and close everything in permanently. Everything that lives inside a wall or a ceiling: every cable, every conduit, every duct, every sensor wire, every refrigerant sleeve — it all has to go in at first fix. Once those surfaces close, you're done. Anything you missed means chasing, re-plastering, repainting, and a property that looks like it had surgery done on it six months after completion. The electrical specification for this project centred on 3-phase supply — 3 × 230V at 400V TN-S, to Spanish REBT regulation throughout. For an American client accustomed to 120V/240V single-phase, this needed a short explanation. The Spanish 3-phase system carries significantly more capacity — the AC system, future EV charger, pool pump, and full household load can all run simultaneously without stressing the supply. We pre-wired approximately 18 circuits across the three phases, balanced to within 10%, and reserved a dedicated conduit and MCB position for a future EV charger in the garage. The consumer unit itself will be fitted at second fix, once the building work is complete — but every circuit is labelled, tested for continuity, and documented so that second fix is straightforward. The ducted AC and Airzone installation is where first fix really justifies itself as a concept. A ducted air conditioning system is, by design, completely invisible in a finished property. The Daikin central air handling unit sits in a ceiling void. The galvanised steel ductwork runs through structural ceiling spaces to ceiling diffusers in each room. The Airzone zone dampers — motorised flaps that open and close individual zones independently — are built into the ductwork. All of it disappears before the finishes go on. That invisibility is exactly why it has to go in now, at first fix, and why the Airzone control wiring — the zone bus cable, the temperature sensors, the thermostat positions — all had to be pre-wired inside the wall cavities before plaster. The system will give the family independent temperature control in every room of the house: living area, kitchen, master bedroom, and three further bedrooms, each with its own thermostat, each able to be set or switched off independently. That level of control, in a property that looks completely standard from every finished surface, is what first fix makes possible.
Chint Consumer Unit + Auto-Reset RCDs, Alhaurín el Grande
The client owns a finished villa in Alhaurín el Grande — fully decorated, fully lived-in, on a 3-phase 230 V/400 V supply — with an existing Chint-branded electrical installation that the previous owner specified throughout. Over the past year the original consumer unit had become unreliable: nuisance trips on the outside lighting and security circuit during winter rain, a main switch that no longer felt mechanically positive, and a board that had been added to piecemeal over the years until the labelling no longer matched the circuits behind it. The client called us with a clear brief and an equally clear constraint. The brief: replace the consumer unit, restore safe and reliable protection across the whole property, and do it without trips that wake the family up at three in the morning when a wet weather seal lets a few drops of moisture into an outdoor PIR. The constraint: a full rewire — chasing every wall, lifting every floor, replastering and redecorating the entire villa — was not on the table. Not now. The property is finished, the family lives in it every day, and there is a major reform planned in roughly two to three years that will involve opening the structure anyway. Doing a full rewire today and then opening the same walls again in 2028 makes no sense for anyone. This case study explains the engineering decisions on a project where the brief is not 'rebuild from scratch' but 'make the existing installation as safe, reliable, and future-ready as it can be — and brand-match it cleanly to what is already there.' It covers why the client specified Chint (and what makes Chint a credible specification on a Spanish residential board), why we fitted Circutor REC4 self-reclosing RCDs on every one of the 8 RCD groups rather than mixing fixed and auto-reset devices, how the 18 final circuits were grouped across the 8 RCDs and balanced over the three phases L1, L2 and L3, and how the whole assembly was pre-built off the wall before a single live cable was disconnected from the existing supply.
Solar Array Extension — 6× 500 W Panels on Deye 8 kW Hybrid, Mijas
The client owns a hillside villa in Mijas built on a steep south-west-facing slope. The original solar installation — fitted two years ago by another installer — paired a 3-phase Deye SUN-8K-SG04LP3 hybrid inverter with a modest rooftop array. The inverter has been working faultlessly, the monitoring data is clean, and the consumption profile of the house has grown: a heat pump went in last winter, and a second air-conditioning zone was added during the summer. Generation no longer covers consumption. The client called us in to extend the array. The original installer had specified an 8 kW inverter with deliberate headroom — the Deye SUN-8K-SG04LP3 will accept up to 10.4 kW of PV on its DC side across two MPPTs (maximum 12.5 A short-circuit current per MPPT, 500 V open-circuit), and the existing rooftop string used only one of the two MPPTs and only a fraction of the available DC capacity. That headroom is the entire reason this extension makes economic sense: adding panels into the spare MPPT input means more generation without the cost of a second inverter, without changing the hybrid storage architecture, and without re-doing the grid-connection paperwork from scratch — only a CAU update to reflect the new total kWp. The rooftop was already built out and there was no mechanically sound additional roof area with the right pitch and orientation. The site engineering question was therefore where to put the extension. The answer the property gave us was the south-facing area directly underneath the main wooden deck on the lower side of the villa, where there is a clear view to the sky between roughly 9 am and 5 pm in winter and dawn-to-dusk in summer. The slope under that deck falls away sharply on a typical Mijas hillside gradient, and the only practical way to mount panels there in a way that survives twenty-five years of Andalucian sun, winter rain and the occasional Levante gust is a bespoke hot-dip galvanised steel A-frame structure built off the existing reinforced concrete columns and the bedrock below. This case study covers why the inverter headroom made the extension the right economic call, why we built a custom galvanised frame rather than buying off-the-shelf rails, and how the 3.0 kWp extension was electrically sized to drop straight into the spare MPPT input on the existing Deye inverter without changing a thing on the house side of the wiring.
EV Charger Installation — Orbis Viaris 7.4 kW Single-Phase, Pedestal Mount, San Pedro de Alcántara (Marbella)
The client owns a villa in San Pedro de Alcántara on the western edge of Marbella with a German plug-in hybrid in the household and an order placed for a fully electric replacement arriving later in 2026. The property has no enclosed garage — parking is on the open driveway alongside a landscaped garden — so a wall-mounted charger inside a structure was not an option. The client wanted a charger that could deliver a full overnight charge for either the current plug-in hybrid or the future EV, looked like part of the garden rather than an industrial fitting, and was supplied by a Spanish manufacturer rather than a US or Chinese OEM with uncertain spare-parts availability through a Spanish distributor. The answer was a single-phase 7.4 kW Orbis Viaris Uni — Spanish-designed and Spanish-manufactured by Orbis Tecnología Eléctrica out of Madrid, with full local distribution and a Spanish-language warranty network — mounted on a bespoke hot-dip galvanised steel garden pedestal rather than against a wall. The villa is on a single-phase 230 V Endesa supply with sufficient contracted power to run a 7.4 kW (32 A) charger overnight under the dynamic load-management mode the Viaris supports natively, so no contracted-power upgrade was required and no costly conversion to a three-phase supply was needed. The supply cable was pulled in a buried polyamide corrugated conduit from the consumer unit on the inside wall of the technical room, out under the driveway in a 60 cm deep trench with warning tape, and up through the hollow galvanised pedestal to the rear of the charger enclosure. This case study covers the full ITC-BT-52 compliant install: how the Viaris Uni 7.4 kW was specified against the household's existing single-phase contracted power and realistic overnight charging needs, why a pedestal in the garden was the right answer rather than a wall mount, the bespoke galvanised pedestal fabricated locally in San Pedro to match the existing garden ironwork, the underground RZ1-K (AS) 3G6 mm² supply route, the dedicated 2-pole 40 A Type A RCBO with integrated 6 mA DC fault detection on the consumer unit side, the RFID Mifare authentication setup so only family vehicles can draw a charge, and the test certificates (continuity, insulation, earth-loop, RCD trip and residual DC) that closed out the REBT paperwork.
