Frequently Asked Questions about Home Energy Storage System 30kWh

What type of property is the 30kWh home energy storage system suitable for?

With its 30kWh high-capacity design, this system is ideally suited for large homes (4–6 bedrooms), villas, and small commercial premises. The dual-battery module configuration (2 × 15kWh) meets the entire day's electricity needs, providing continuous power for high-load appliances such as air conditioners, water heaters, and kitchen equipment. For commercial applications with higher energy demands, capacity can be further expanded by connecting multiple units in parallel.
How does the 11kW hybrid inverter perform under high load?

Its 11kW rated output supports the simultaneous operation of multiple high-power appliances—such as air conditioners (3–5kW), water heaters (3kW), and kitchen appliances (2–3kW). It boasts a conversion efficiency exceeding 98% and features an MPPT range of 120–500V DC with dual trackers and a maximum PV input of 11kW, ensuring stable power supply during peak usage periods.
Can the dual battery modules be expanded or replaced independently?

Yes. The stackable modular design allows each 15kWh battery module to be installed, replaced, or expanded independently. Users can start with a 30kWh setup (two modules) and easily add more modules of the same specification later without replacing the entire unit. Each module measures 700 × 260 × 510mm and has a manageable weight, facilitating on-site installation.
Does the system support grid-tied and off-grid operation?

The system utilizes a hybrid inverter architecture that supports grid-tied operation—enabling PV self-consumption and feeding excess power back to the grid—while also offering off-grid backup capabilities. In the event of a grid outage, it automatically switches to off-grid mode to ensure an uninterrupted power supply for critical loads, making it particularly suitable for users who require high power supply reliability.
What is the expected lifespan and warranty of the battery system?

It utilizes Lithium Iron Phosphate (LiFePO4) cells with a cycle life of ≥8,000 cycles (95% DOD); based on one full charge/discharge cycle per day, the service life exceeds 20 years. Specific warranty terms vary according to OEM customization requirements; please contact our sales team for a warranty plan tailored to your market strategy.
What OEM and white-label customization options are available?

OLINK offers comprehensive OEM and white-label services, including: brand logo silk-screening and laser engraving, enclosure color customization, packaging design and custom inserts, branding for startup interfaces and mobile apps, and multilingual technical documentation. OLink’s factory features complete production lines and quality control systems, supporting the entire process from sample approval to mass delivery.
What is the MOQ and lead time for bulk orders?

The Minimum Order Quantity (MOQ) and lead time depend on the level of customization. Standard products (without branding customization) typically have a lower MOQ and a lead time of approximately 2–4 weeks; for extensive OEM customization projects, the MOQ and lead time are assessed based on specific requirements. We recommend that distributors place a small initial trial order to validate the market before proceeding with bulk procurement. Please contact our sales team for a specific quote.
