Power Package — Off-Grid Energy Storage (10 / 15 / 20 kWh)
Power Package — Off-Grid Energy Storage (10 / 15 / 20 kWh)
Reliable off-grid power for home, cabin, or worksite
A compact, modular energy storage system available in 10 kWh, 15 kWh, and 20 kWh sizes.
Designed for off-grid living, backup power, or to pair with solar generation, it stores clean energy,
delivers steady AC loads, and gives you clear status and remote monitoring so you know exactly how much runtime you have.
Benefits
Keep lights, refrigeration, and essential outlets running during outages so daily life stays on schedule.
Cut fuel use and noise by relying less on generators—save money and reduce hassle.
Use stored solar energy when the sun isn’t shining to smooth your power availability.
Simplify system planning with clear capacity options and predictable runtime for appliances.
Monitor performance remotely to avoid surprises and manage charge/discharge around your needs.
Features
Three capacity options: 10 kWh, 15 kWh, and 20 kWh to match different household or site needs.
LiFePO4 battery chemistry with integrated Battery Management System (BMS) for safe, long life.
Modular, stackable enclosure for easy expansion or service access.
Supports common 48 V inverter systems and works with solar charge controllers or hybrid inverters.
Fast charge capability from solar or grid sources with controlled input to protect battery health.
Remote monitoring and basic control via app or web portal (Wi?Fi/Ethernet options).
Built-in safety protections: over/under voltage, overcurrent, short-circuit, and temperature management.
