Battery scenarios
Sketches of how a home, office, or factory battery might be sized in Southeast Asia. These are not customer installs. No owner, installer, or meter reading is attached. Bills and payback are assumptions.
A Klang Valley bill, sketched
A sketch for a Shah Alam household: an 8 kWp roof and a 13.5 kWh Powerwall 3. It assumes a bill of RM 480 before, and RM 60 after six months. This is not a metered install.
Sketch assumptions
- Monthly bill reduced from RM 480 to RM 60
- Self-consumption rate increased from 40% to 85%
- Battery covers overnight AC usage (2 split units)
- Exported only 3 kWh/day to grid under NEM 3.0
Landed backup in Singapore, sketched
A sketch for a landed home in Bukit Timah: 6 kWp of solar and a 10.2 kWh BYD BatteryBox. It assumes backup is the reason to add a battery, and a bill moving from S$320 to S$140. This is not a metered install.
Sketch assumptions
- Monthly bill reduced from S$320 to S$140
- Provides 6-8 hours of backup during outages
- LFP chemistry well-suited for Singapore heat
- Estimated 10-year warranty with 80% capacity retention
Bangkok peak shaving, sketched
A sketch for a Sukhumvit co-working space: three Huawei LUNA 2000 units (30 kWh) with 20 kWp of solar. It assumes afternoon peak shaving and demand charges 40% lower. This is not a metered install.
Sketch assumptions
- Demand charges reduced by 40%
- System ROI in under 5 years
- 3-phase setup covers all office circuits
- Remote monitoring via Huawei FusionSolar app
A Cebu resort, sketched
A sketch for a small Cebu beach resort: four Pylontech US5000 modules (19.2 kWh) with 15 kWp of solar. It assumes diesel running much less of the evening. This is not a named resort.
Sketch assumptions
- Diesel generator runtime reduced by 70%
- Fuel cost savings of ₱25,000/month
- Silent operation improved guest experience
- Stack expandable to 38.4 kWh
A Jakarta factory, sketched
A sketch for a Cikarang garment factory: a 100 kWh BYD commercial battery and 60 kWp of solar. It assumes peak demand 35% lower and electricity cost 25% lower. This is not a metered install.
Sketch assumptions
- Peak demand reduced by 35%
- Overall electricity cost down 25%
- Battery provides 2-hour backup for critical machinery
- PLN demand tariff savings compound annually
