B2B Purchasing Advantages
Modular & Tool-Free Cable-Free Expansion
Expand system capacity effortlessly from 5.12kWh up to 25.6kWh by stacking up to five 51.2V 100Ah battery modules onto a single base unit. The internal stacking mechanism eliminates messy external interconnect cables, significantly lowering labor hours and job-site installation complexity.
All-in-One Hybrid Inverter Architecture
Equipped with an integrated 5.5kW off-grid hybrid solar inverter and a high-capacity 100A MPPT solar charge controller. The system accepts a broad MPPT PV operating range of 120Vdc to 450Vdc with a maximum PV input voltage of 500Vdc, maximizing energy yield across varying environmental conditions.
Multi-Protocol Smart Connectivity & APP Remote Monitoring
Integrated smart BMS protection board with multi-protocol communications including RS485, CAN2.0, SD, Wi-Fi, and GPRS. Installers and end-users can manage performance, track generation, and run diagnostic checks remotely via the mobile app platform.
Versatile Multi-Port Energy Distribution
Offers robust 230Vac/50Hz single-phase pure sine wave AC output alongside auxiliary DC USB and Type-C fast-charging ports for critical direct-DC devices during grid failures.
FAQ
Q: How difficult is the stacking process?
A: The LS series features a modular, tool-free quick-stack design with quick-connect bus terminals integrated into each module's casing. You simply stack the battery units sequentially onto the base module without running external interconnecting DC cables.
Q: Can I start with a single 5.12kWh battery module and expand the storage capacity later as power demand grows?
A: Yes, the system supports scalable expansion from 5.12kWh up to 25.6kWh. End-users can add matching 51.2V 100Ah battery modules to the stack at any time without needing to replace or reconfigure the top 5.5kW hybrid inverter unit.
Q: Can this hybrid system operate seamlessly with existing grid power and diesel generators?
A: Absolutely. The hybrid inverter supports wide AC input voltages (90–280Vac) and connects directly to public grids or standby generators. The system automatically manages automatic transfer switching (ATS) to provide uninterrupted power during grid failures.
Q: Does the system include auxiliary DC outputs for direct-DC appliance loads?
A: Yes. In addition to standard 230Vac pure sine wave AC output, the system is equipped with onboard USB and Type-C DC fast-charging ports. This allows users to power mobile devices, routers, and emergency DC electronics directly without turning on the AC inverter stage.
Q: How do installers and end-users monitor power generation and battery performance in real time?
A: The system features multi-protocol communications (CAN2.0, RS485, Wi-Fi, GPRS, and SD card). Users can monitor battery state of charge (SoC), PV generation, load consumption, and system health remotely via a dedicated iOS/Android Mobile App.
