wenergy’s residential energy storage systems deliver reliable, intelligent, and scalable power for modern households. Our solutions integrate cutting-edge battery technology with smart energy management to maximize self-consumption, reduce grid dependence, and ensure uninterrupted power—even during outages.
● Solar Self-Consumption:
Store excess solar energy for nighttime or cloudy days, slashing electricity bills by up to 80%.
● Backup Power:
Seamless transition to battery power during grid outages (10ms switch time).
● Peak Shaving:
Avoid high tariff periods by using stored energy during peak hours.
● Off-Grid Living:
Full energy independence with scalable battery capacity (5kWh–30kWh).
