Case Studies | Baiya Energy — Residential, C&I & Utility Storage + HV Circuit Breakers

Case 01 · Residential Battery · Germany

15 kWh wall-mount storage cuts a Bavarian family's bill by 60%.

Family Müller · Munich suburbs · 8 kW rooftop PV · 12,000 kWh/yr consumption at €0.40/kWh.

The Challenge

Daytime PV surplus wasted, evening consumption at peak tariff
Rising grid-outage frequency in 2025 — family wanted backup power
Goal: maximize self-consumption, minimize the €4,800/yr bill

The Solution — Baiya 51.2 V 300 Ah wall-mount

Peak shift: charge from PV daylight, discharge into evening load
Backup: full charge sustains 48 h of essential household load
Smart BMS with mobile app for live SoC and cell balancing

Case 02 · Telecom Off-Grid · South Africa

50 remote cell towers ditch diesel for solar-plus-storage.

MTN South Africa · 50 rural base stations · 4–6 h daily grid outages · previously diesel-only.

The Challenge

Diesel generation at $0.85/kWh — over $120,000/yr in fuel
Frequent generator maintenance, high remote-technician travel cost
Lead-acid batteries lasted only 2–3 years, repeated replacement

The Solution — Baiya 48 V 200 Ah LiFePO4 + PV

PV-charged off-grid architecture, night discharge from battery
6,000-cycle LiFePO4 chemistry → 10+ year deployment life
Remote BMS telemetry replaces on-site inspection rounds

Case 03 · Commercial & Industrial · California

ZBox 200 flattens demand charges at a San Jose factory.

Mid-size manufacturing plant · 80,000 kWh/month · 350 kW peak demand · CA time-of-use tariff.

The Challenge

Morning 9–11 a.m. equipment ramp created a 350 kW demand spike
Demand charges = 40% of the monthly bill, eroding margin
ESG audit required a visible green-energy strategy

The Solution — 2× ZBox 200 outdoor cabinets (200 kWh)

Peak shave: battery discharges during demand-window spikes
Off-peak charging at $0.11/kWh, discharge into $0.42/kWh peak
AI load-forecast controller optimizes charge/discharge daily

Case 04 · Containerized Microgrid · Dubai

A Palm Jumeirah resort runs 78% on renewables — quietly.

5-star beachfront resort · 280 rooms · 6,000 MWh/yr · 1.2 MW summer peak · Net-Zero-by-2030 pledge.

The Challenge

Grid voltage swings in high season damaged sensitive villa AV systems
Diesel backup was noisy — incompatible with the luxury brand experience
Extreme space constraints on the artificial island

The Solution — Full wind / solar / storage microgrid

200 kW rooftop-canopy PV shading the guest parking lot
50 kW vertical-axis wind turbines lining the beachfront

Case 05 · High-Voltage Switchgear · Australia

Queensland 330 kV substation upgraded in 5 months, not 24.

Queensland transmission utility · 25-year-old 330 kV site · four dead-tank breakers replaced.

The Challenge

Legacy breakers leaked SF6 above 1%/yr — urgent replacement
Constrained site — new equipment had to be compact
5-month deadline; incumbent supplier quoted 18–24 months
Strict IEC certification required for the Australian grid

The Solution — 4× Siemens Energy 3AP2-DT 330 kV

Manufactured in China — one of Siemens Energy's two global bases
Delivered in 5 months (US-plant backlog was 2+ years)
Integrated DTC current transformers — no CT platform civil work
Spring operating mechanism, 10-year maintenance-free — ideal for the outback
