Product Description

☀️

This battery serves as the essential partner to solar photovoltaics, acting as the missing link that transforms daytime energy generation into a 24-hour power solution. By addressing the "Duck Curve" phenomenon—where excess solar power is generated during the day and bought back at higher rates at night—this system maximizes efficiency and investment returns.

Our solution focuses on high self-consumption rates and energy independence, capturing peak solar energy and storing it for evening use. It creates a closed-loop ecosystem where homes generate, store, and consume their own power, minimizing reliance on external infrastructure.

Frequently Asked Questions

Q What is the cycle life and warranty of these batteries?
The battery system features a cycle life of ≥8,000 cycles at 85% Depth of Discharge (DOD) at 25℃, supported by a comprehensive 10-year warranty.
Q Which inverter brands can I use with this system?
It is compatible with major brands including Sungrow, Ginlong Solis, Growatt, GoodWe, Deye, Solplanet, Hypontech, Livoltek, MUST Solar, Sunways, Chint Power, KSTAR, and more.
Q How many units can be connected in parallel?
The system is highly scalable, supporting up to 16 units in parallel to meet larger energy storage requirements.
Q What customization options are available?
We offer customization for battery dimensions, capacity, interface types, IP ratings, high-altitude adaptation (up to 3000M), and specific charging/discharging current requirements.
Q How does this battery solve the "Duck Curve" inefficiency?
It captures surplus solar energy during peak daylight hours—when production exceeds home demand—and stores it for use during the evening, significantly reducing reliance on expensive grid power at night.
Q What safety protections are integrated into the system?
Managed by a high-performance PACE BMS, the system includes built-in protection against overcharging, over-discharging, short circuits, overcurrent, and temperature extremes.
