PowerStack 48V/314Ah – Your Scalable, Reliable Energy Core for Homes & Businesses Worldwide

Your Scalable, Reliable Energy Core for Homes & Businesses Worldwide

1. Japan – Urban Apartment Backup & Self-Consumption in Tokyo

Customer Profile: Eco-conscious apartment owner in a dense city, with limited roof space for solar but high electricity costs and earthquake preparedness needs.
Need: Store energy from a small balcony PV system, provide critical backup for lights and comms during frequent tremors, reduce grid reliance.
Installation Conditions: Installed in a dedicated indoor utility closet (IP20), space-constrained, moderate humidity.
Case: A single 48V/314Ah unit is paired with a compatible 5kW hybrid inverter and 3kW of balcony-integrated PV. The system maximizes self-consumption of solar energy, charging during the day and powering evening loads. Its <100ms switchover provides seamless backup during grid outages caused by seismic activity. The compact footprint (740x380x250mm) fits perfectly in the apartment's storage room.
Key Advantages: Compact, floor-mounted design for tight spaces; UN38.3/IEC62619 certified for safe residential use; long cycle life (≥6000 cycles) ensures long-term savings; RS485/CAN compatibility works with major Japanese inverter brands.

2. Philippines – Off-Grid Solar Hub for a Remote Island Homestay

Customer Profile: A family-run tourism homestay on a small island without grid connection, reliant on expensive and noisy diesel generators.
Need: Achieve 24/7 quiet, clean power for guest amenities (lights, fans, fridge, water pump) and maximize solar use.
Installation Conditions: Tropical, high humidity and salt air, installed in a well-ventilated backroom.
Case: Four units (60kWh) are configured in parallel with a 15kW off-grid inverter and 20kWp of rooftop solar. The system runs the homestay entirely on solar during the day, using battery power at night. The generators are now only for emergency backup during rare prolonged cloudy periods, cutting diesel costs by over 80%.
Key Advantages: Modular parallel setup allows starting small and expanding with business growth; discharging temperature range up to 65°C suits tropical climates; 15-year design life offers a strong return on investment.

3. India – Uninterrupted Power for a Home Clinic in Rural Uttar Pradesh

Customer Profile: A small private clinic in a village plagued by daily, extended power cuts (load-shedding).
Need: Reliable 24/7 power for refrigeration of medicines, basic medical equipment, and lighting.
Installation Conditions: Hot climate (often >40°C), dusty environment, installed in a dedicated indoor storage room.
Case: Two battery units are connected in parallel (30kWh total) to a 10kW off-grid inverter. This system, coupled with a 8kW diesel generator, ensures the clinic never loses power. The batteries handle all loads immediately during a grid failure, starting the generator only for prolonged outages, significantly reducing fuel cost and noise.
Key Advantages: Supports up to 16 units in parallel for easy capacity expansion; robust LiFePO4 chemistry safely handles high ambient temperatures; strong BMS pre-charge ensures reliable switching.

4. Vietnam – Peak Shaving for a Family-Run Convenience Store in Hanoi

Customer Profile: A small shop with high afternoon/evening load from refrigeration and air conditioning, facing steep time-of-use electricity tariffs.
Need: Reduce monthly electricity bills by shifting energy consumption away from peak price periods.
Installation Conditions: Installed indoors behind the shop, subject to high humidity seasons.
Case: One 15kWh unit is integrated with a 6kW hybrid inverter. The battery charges from the grid during low-cost overnight hours and discharges during the expensive afternoon peak to power the store's coolers and AC, significantly reducing demand charges.
Key Advantages: High recommended charge/discharge current (150A) allows for powerful cycling; intelligent BMS with remote monitoring lets the owner track savings via smartphone; CE/IEC62619 certification ensures safety for commercial use.

5. Brazil – Net-Metering Optimization for a Suburban Home in São Paulo

Customer Profile: Middle-class homeowner with a rooftop PV system under Brazil's net-metering scheme, seeking to maximize the value of self-generated energy.
Need: Store excess solar generation for use at night instead of exporting it at lower value, and provide backup during occasional grid instability.
Installation Conditions: Installed in a garage or utility room, mild climate with occasional high temperatures.
Case: A single unit is paired with a compatible hybrid inverter. It stores surplus solar energy produced midday. This energy is then used in the evening, dramatically increasing the household's self-sufficiency and protecting against future changes in net-metering policies.
Key Advantages: Seamless compatibility with most hybrid inverters simplifies system design; excellent cycle life ensures economic benefit over the long term; compact and neat design is acceptable for residential garage installation.
