At AA Solar, we pride ourselves on delivering tailored solutions for residential solar installations, helping homeowners achieve energy independence and sustainability. Recently, we were approached by a Northland homeowner who was dissatisfied with their existing off-grid setup. Their lead-acid batteries were underperforming, and they felt overly reliant on a generator for backup power. Our team stepped in to provide a comprehensive upgrade to their system.
The Challenge
The homeowner needed a reliable, efficient, and sustainable solution to meet their energy needs without depending on the grid or frequent generator use. Our Solar Engineers conducted a detailed diagnostic of the current setup, including energy loads, backup requirements for cloudy days, and overall system performance.
The Solution
After evaluating the homeowner's needs, we recommended:
- 18 x 440W Bifacial Double Glass Solar Panels for enhanced energy generation.
- Victron MultiPlus-II 48/8000/110-100 Inverter/Charger for seamless power management.
- 4 x Pylontech US5000 Lithium Batteries to ensure long-lasting and efficient energy storage.
