The residential property suffered from frequent grid power instability and prolonged outages, causing severe disruption to household appliances and relying heavily on expensive generator operation. The client required a quiet, reliable, and maintenance-free clean energy solution capable of sustaining essential domestic loads day and night..
The HUMELIX LIMITED engineering team designed and executed a clean roof-mount installation for a 10-panel (4.5 kWp) solar PV array positioned for optimal daily irradiance. On the indoor distribution wall, our team installed a wall-mounted LiFePO4 battery pack, a 60A MPPT charge controller, and a robust 3.5 kVA Wakatek Pure Sine Wave inverter. We integrated dedicated DC/AC distribution panels featuring Surge Protection Devices (SPD), Double-Pole MCBs, and earth-fault protection to guarantee system longevity and maximum safety.
Successfully transitioned the residence to a dependable, continuous solar power supply. Grid dependence and monthly fuel costs were reduced by over 85%, while providing clean, stable single-phase power (230\text{V}, up to 15.2\text{A} continuous load) without voltage drops or unexpected interruptions.
Panels: 10 × 450W High-Efficiency Monocrystalline Solar Panels Max Array Output: 4,500 \text{ Watts} DC power
Rigorous safety protocols observed during roof mounting and ladder positioning.
Full deployment of technician PPE (safety helmets, high-visibility vests, insulated boots, and gloves).
Pre-commissioning testing, including PV string open-circuit voltage (V_{oc}) verification, polarity checks, short-circuit current (I_{sc}) testing, and AC insulation resistance testing prior to system activation.
Conducted full circuit-balancing checks across the residence's distribution board and handed over a customized energy-management guide to the owner, outlining load prioritization techniques during non-sunny hours to prolong battery lifespan.
