5 kVA · 5 kWp · 10 kWh
01 · Initial challenge
The situation before installation.
The household relied on a petrol generator most evenings and during frequent daytime outages. Noise, fuel runs and voltage swings were damaging appliances and disrupting work-from-home schedules.
02 · Energy requirements
≈ 14 kWh daily consumption across lighting, fans, refrigeration, entertainment and home office
≈ 3.2 kW peak simultaneous load
Overnight backup for essential circuits
03 · System configuration
Inverter5 kVA hybrid inverter (single phase)
Solar array5 kWp — 9 × 550 Wp monocrystalline modules
Battery storage10 kWh LiFePO₄ lithium
IntegrationGrid + generator automatic changeover
MonitoringMobile app with remote support

05 · Results
Design outcomes.
Design yield ≈ 6,159 kWh of solar energy per year (4.5 peak sun hours, 75% system efficiency)
Battery reserve ≈ 10.1 hours at a 800 W average load
Measured generator-runtime and fuel savings will be published after 12 months of monitoring data
