Description
Product Overview
The BK-SCPSS-5~25 KWh is a floor-standing, stackable solar-plus-storage system that merges a 5 KW hybrid inverter with 5–25 KWh of LFP (LiFePO₄) batteries in a single tower. Each 5 KWh module slides and locks into place—no cables, no tools—allowing users to start small and expand to 25 KWh as budgets grow. Delivering 1.5–11 KW of continuous power, it covers everything from apartments to small factories in one plug-and-play cabinet.
Application
- Urban Apartments & Villas
Start with 5 kWh for essential circuits, add modules as PV grows.
- Rural Micro-Grids
15–25 kWh towers power schools, clinics or small farms without diesel.
- Small Commercial
10 kWh + 6 kW hybrid inverter for a café or workshop—daytime PV sell-back, nighttime battery supply.
- Emergency Backup
UPS mode keeps servers, medical devices or telecom towers online during blackouts.
- Retrofit & Rental Housing
Wheel-in towers, plug into existing PV strings—no rewiring, low CAPEX.

FAQs
UPS stands for Uninterruptible Power Supply and is a device that provides a continuous supply of power to protect critical loads from power failures or fluctuations.
The main role of a UPS is to provide a backup power source to ensure that critical equipment can continue to operate when utility power is interrupted or unstable, avoiding data loss or equipment damage.
UPS is mainly divided into three types: offline, online and online interactive.
When choosing the power capacity of the UPS, you need to consider the total power demand of the load, it is usually recommended to choose a slightly larger than the total load power of the UPS to ensure sufficient standby time.
The standby time of a UPS depends on the battery capacity and load power. Standby time usually ranges from 10 minutes to several hours, and the specific needs can be determined according to the actual application scenario.
