Option 1:
Single 500 kW integrated Megarevo inverter
13 battery modules connected in series for one string.
1 PDU is assigned to manage one string.
There are total 5 independent strings in parallel, 65 battery modules in total.
Sail Solar 20'ft container 500kw 1000kwh is a fully integrated, plug-and-play energy storage solution for commercial and industrial (C&I) solar power projects and off/on-grid energy management. It integrates high-performance LiFePO4 battery packs, Inverter, intelligent BMS & EMS, precision HVAC temperature control, and multi-level fire protection systems in one pre-assembled container, eliminating complex on-site assembly and shortening commissioning time drastically.

HVAC System
It stabilizes operating temperature for battery modules and power electronics, prevents overheating or low‑temperature derating.
Warning System
Continuously monitors temperature, smoke and electrical status across the container.
Fire Fighting System
Dedicated fire suppression responds rapidly upon fire hazard signals, executes fire‑extinguishing actions to protect battery and power equipment inside the cabinet.
Inverter
Performs DC‑AC power conversion between battery bank, solar PV input, grid and local C&I loads. It manages battery charging and discharging, and handles grid‑tied power exchange for peak shaving and solar self‑consumption.
PDU
Power distribution unit for each battery string. It conducts current distribution, over‑current protection, and collects real‑time battery data via CAN bus, supervising every series‑connected battery string independently.
Battery Module
Multiple modules are assembled in series to build high‑voltage battery strings, storing renewable energy and supplying power on demand.

People May Ask
1. How is the 20ft container BESS shipped? Is it fully pre-tested?
It is shipped as a complete single 20ft standard container unit, no split shipment. The entire system (batteries, PCS, BMS, cooling, fire system, wiring) is fully assembled and 100% factory tested before shipping. You receive one ready-to-deploy container, no missing parts, no on-site assembly confusion, and it fits all standard container ships and truck transport worldwide.
2. 20ft container ESS vs split indoor 500kw+1000kwh energy storage system: which is better?
For C&I users, container type is superior in most cases. Container ESS: outdoor deployable, no need to occupy valuable factory indoor production space, integrated fire & cooling system, no indoor fire safety pressure. Split indoor system: requires dedicated fire-proof room, professional ventilation, longer construction period, and higher civil engineering cost. For factories with limited indoor space or strict fire codes, 20ft container BESS is the safest and most economical choice.
3. Is the 20ft container easy to expand for future project upgrade?
Yes. The system supports parallel connection of multiple 20ft container units. If your factory load increases in the future, you can add more 500kW/1000kWh container or Sail Solar all in one 241kwh air-cooled outdoor cabinet, without abandoning existing equipment. It perfectly matches phased investment and scalable C&I energy storage projects.
