Family Holiday Home: Powering Remote Comfort for Generations to Come
This off-grid system was designed to power a remote family holiday home and cottage with year-round reliability and low maintenance, despite limited winter sunshine and long-term access constraints. With construction set to span two years, the system was engineered to support both the building phase and long-term family use.


Location: Remote holiday home
Client Type: Extended family
System Type: New off-grid solar power system with backup generator
Key Objectives: Reliable power for two dwellings with remote monitoring and automatic generator backup
The Challenge
This extended family was building a holiday home and a separate cottage on a remote site with limited winter sunshine. Their priorities included quiet operation to preserve the tranquillity of the setting and a reliable power supply throughout the two-year construction period and beyond. The architectural design would restrict future access to both the solar array and power shed, so long-term reliability and low maintenance were essential. Power-hungry appliances such as electric ovens and hot water systems also needed to be factored in.
Our Solution
We designed and installed a managed AC-coupled off-grid system tailored for year-round reliability.
System Specs: 24 kW solar array, 120V 130 kWh maintenance-free lead-acid battery bank, 15 kW inverter, and a 20 kW auto-start diesel generator
Remote monitoring and generator automation ensure the system is hands-off and hassle-free
System sized for future-proofing both homes, with flexibility during the building phase
The Outcome
The family now enjoys a dependable power supply with minimal generator usage. The system has operated with 100% reliability since commissioning, giving the family peace of mind and allowing them to enjoy their home without worrying about power.
Savings: Low ongoing fuel and maintenance costs thanks to robust design
Reliability: Power available throughout construction and now for long-term occupancy
