For 50KW off-grid projects targeting remote and island microgrids, sourcing directly from China compresses landed cost by 12–22% versus buying through regional distributors. This guide gives you the exact BOM, container-load economics, supplier shortlist and delivery timeline our desk uses for 50KW-class projects every week.

BOM for 50KW off-grid systems
- Modules: 620W TOPCon bifacial or 585W TOPCon glass-glass, tier-1 Chinese
- Inverters: Sungrow/Huawei/GoodWe string, hybrid or central depending on scale
- Racking: Antaisolar/Arctech rooftop or Xiamen Grace ground-mount
- BOS: DC cable H1Z2Z2-K, MC4 EVO2 connectors, combiner boxes, AC panel
- Optional: LFP battery (CATL/BYD/EVE), monitoring (Sungrow iSolarCloud/Huawei FusionSolar)
Container economics
For 50KW systems, plan container mix carefully — modules ship separately from inverters and structure. A well-optimised 50KW project fills 1–8 x 40'HC containers depending on wattage class, structure type and battery inclusion.
Supplier shortlist
- Modules: LONGi Hi-MO X10, Jinko Tiger Neo, JA DeepBlue 4.0, Trina Vertex N
- Inverters: Sungrow SG (utility) or SH (hybrid), Huawei SUN2000, GoodWe MT/HT
- Batteries: CATL TENER, BYD Battery-Box, EVE MB56, Pylontech Force H2
- Structures: Antaisolar/Arctech/Xiamen Grace with local wind zone certification
Payment & timing
Standard payment 30/70 TT or LC at sight. Lead time 40–65 days PO to CIF arrival. For 2026 delivery slots, order 60–75 days ahead of required commissioning.
Frequently asked questions
QCan I turnkey a 50KW off-grid project from one Chinese supplier?
Yes — several tier-1 OEMs (LONGi, Trina, Sungrow) offer bundled turnkey with 6–10% price advantage vs component sourcing.
QWhat's the minimum order for CIF direct?
1 x 40'HC container (roughly 40 kW of modules or 200 kWh of battery). Below that, use consolidators.
QHow do I handle inspection?
Third-party PSI (SGS/Intertek/TÜV) at $800–1500 per inspection. Always required for orders above $50k.
