4kVA Backup Power Solution
Bravestone Energy Solutions deployed a 4kVA backup power system for a 4-bedroom bungalow in Ajah, Lagos State. The solution powers all lighting points, freezers, three televisions, and other essential appliances, ensuring uninterrupted power during grid outages.
We identified appliances that stay on during power outages, the busiest rooms at night, and the positions of key equipment. At the distribution board, we mapped the circuits and measured typical loads including lighting, fridge and freezer, TV and streaming devices, Wi-Fi, and fans. This assessment formed the basis for designing a reliable backup inverter solution.
