Designed, assembled and tested in our own factory — same cell platform, same BMS philosophy, same string architecture.
Architecture, BMS and Software — All In-House
String Architecture
Every string on its own modular PCS — a fault means proportional derating, never a system-wide outage.
Active-Balancing BMS
Charge redistributed between cells during operation — protecting usable capacity, safety and cycle life.
Intelligent O&M Platform
IEC 102/104 & MQTT, EU/NA local servers, real-time alarms — unattended operation by default.

Every MARWELL SOLAR system is assembled and integrated in our Zhongshan, Guangdong factory — battery modules, BMS, PCS, cooling and fire protection go into the enclosure as one tested system, not separate boxes to be figured out on site.
Before any unit ships, it goes through a full factory acceptance test: charge-discharge cycling, BMS protection checks, communication verification and thermal run. What arrives at your site is a system that has already run.
After delivery, our O&M platform keeps watch over every system in the field, with data servers in both Europe and North America for fast, compliant remote monitoring.
A Decade of Hands-on BESS Deployment
Safety first — from cell audits to system-level fire-safety design, across the entire project cycle.
Reliability and availability — string architecture keeps every battery string independent: proportional derating instead of system-wide outages.
Care-free battery management — active balancing BMS and intelligent O&M keep every cell consistent, so capacity fade stays predictable.
End-to-end service — design, commissioning, 24/7 monitoring, extended warranties and performance guarantees from one partner.
