Photovoltaics and storage, sized for the site — not for the brochure

Design, installation and operation of PV and battery storage systems in Croatia: grid-synchronous, hybrid or fully off-grid. Control systems are built in our own switchgear workshop.

Scope of work

From yield forecast to ongoing operation

Irradiation in Dalmatia is high, but the distribution grid along the coast and inland carries very different loads. Whether a system is built grid-synchronous, hybrid or as an island network is therefore decided by the site — the connection point, the load profile, how reachable it is for maintenance.

We cover the full chain: yield forecast and viability calculation, sizing of generator and storage, permitting and grid registration documents, installation by vetted local partners, commissioning and ongoing operation.

  • Site and yield analysisShading, orientation, roof statics or plot geometry, load profile and a realistic annual yield forecast.
  • Grid-synchronous systemsSizing, metering concept and registration documents for properties with an existing connection.
  • Off-grid and hybridIsland networks for remote houses, agricultural land and pumping stations, including a backup power concept.
  • Battery storageSized against the measured load curve rather than a rule of thumb, including ageing and cycle considerations.
  • In-house switchgearPurpose-built controls for load management, pumps, heating elements and automatic transfer — manufactured and documented in-house.
  • Installation, commissioning, operationCoordination of trades, handover protocol, user briefing and optional remote monitoring.
Operating modes

Grid-synchronous, hybrid or island network

The three modes differ not only technically but above all in permitting effort, maintenance needs and the consequences of an outage.

Three operating modes — decided on site, not from a catalogue
Operating modeSuitable forWhat it includes
Grid-synchronousProperties with an existing grid connection that want to cut purchased power.Inverters, metering concept, grid registration, optionally a small battery.
HybridSites with a weak or unreliable grid, hospitality, commercial operations.Hybrid inverter, storage sized to the load profile, automatic transfer, backup circuit.
Off-grid / islandRemote properties, agricultural land, pumping stations without a connection.PV generator, battery bank, charge controllers, generator set, dedicated switchgear.
FAQ

Frequently asked

Is off-grid worth it when a grid connection would be possible?
It almost always comes down to the connection run. As soon as several hundred metres of trench, rights of way across third-party parcels or rock work are involved, an island network can be cheaper and available sooner. We calculate both options before anything is ordered.
How long does grid registration take in Croatia?
That depends on the network operator, the system size and how complete the file is. We prepare the documents in full and handle correspondence in Croatian — in our experience that is the single biggest lever on processing time.
Why build your own switchgear?
Because standard cabinets rarely fit projects where PV, storage, a well pump, a scale-resistant heating element and a generator set have to work together. In-house manufacture means one set of documentation, one point of contact and logic that can be extended later.
Do you also handle maintenance?
Yes, as an optional operating service. For off-grid systems we strongly recommend it, because an unnoticed fault there does not raise an electricity bill — it stops the supply.
