Survey
Roof, shade, meter, distribution, plant room and heating system.
Electrical engineering from Merano · across South Tyrol
Energy that
thinks ahead.
Solar PV, batteries, EV charging and intelligent surplus use—clearly designed, professionally installed and coordinated as one understandable energy system.

What we deliver
One system.
Five strong building blocks.
We do not merely sell individual devices. We analyse roof, grid connection, consumption, storage, mobility and heat, then define how all components work together safely and efficiently.
Solar PV
Generate clean electricityWe design and install solar systems from roof survey and module layout to mounting, DC/AC engineering, protection, grid connection and monitoring.
↗02Battery storage
Shift energy through timeWe size storage around the actual load profile: usable capacity, power, inverter, reserve, location and operating strategy must work together.
↗03EV charging
Drive on your own solar powerWe install wallboxes with correct protection, solar-surplus charging, dynamic load management, user control and energy metering.
↗04Energy management
Direct every kWh with prioritiesWe connect solar, storage, EV charging and heat through reliable measurement, understandable priorities and defined safe states.
↗05Surplus heating
Turn electricity into useful heatA water-cooled crypto miner can act as a controllable electrical load and transfer heat to a buffer tank through an exchanger, pumps and safety controls.
↗The Voltalps approach
Generate. Store. Charge. Use the heat.
Energy management measures solar output and grid flow. Direct building loads come first; battery, car and thermal loads then follow the agreed priorities, reserves and limits.

Solar calculator for South Tyrol
What can your roof deliver?
Estimate array size, annual generation, self-use, budget and simple payback. Add storage, EV charging, energy management and miner heat recovery individually.
Calculate solar potential ↗From first measurement to optimised operation
One contact. A clear process.
Understand loads
Annual use, daily profile, peaks, hot water and mobility.
Compare options
PV power, inverter, battery, backup, EV charging and thermal loads.
Define interfaces
Meters, communication, priorities and safe states.
Install
Mounting, cables, protection, labels, testing and documentation.
Optimise
Tune thresholds, reserves and timings using real data.
Real project work
