[Customer Background]
Young couple’s new home challenges: unstable voltage, limited budget, need for future scalability
A young couple in a residential area faced frequent voltage fluctuations that caused router reboots and computer damage. They sought a cost-effective solution for basic energy independence while reserving room for future upgrades (e.g., nursery appliances). Requirements: cover daily office and nighttime base loads (10kWh/day) with minimal upfront investment.

[Design Philosophy]
Silent Efficiency + Easy Expansion: Daytime self-sufficiency, 4-hour nighttime base load
The system focuses on "on-demand supply" and "future compatibility." Solar energy powers appliances directly during the day, charging the battery with excess energy. By evening, the battery reaches 80% charge, supporting 4 hours of AC and base loads at night. The inverter includes parallel interfaces, and batteries can expand to 3 units. Future upgrades take just 1 hour. The EnerWise cloud platform enables "peak/off-peak strategies," purchasing low-tariff grid power to further cut costs.
[Customer Feedback]
"Stable voltage, plummeting bills, and a 3-year expansion plan make this investment worthwhile!"
"Since installation, voltage issues vanished. Movie nights without blackouts? Absolutely!" The couple reported a sharp drop in their first-month bill and praised the silent design. "Ktech even mapped a 3-year expansion plan. Adding batteries later will meet our baby’s needs—this investment pays off!"
