About Us
Source Factory from China
SZ JIUGUAN ENGINEERING CO., LTD designs and manufactures off-grid solar home systems — whole machines and SKD kits — shipped factory-direct to Africa.
Who we are
Built for the Off-Grid Reality
Frequent blackouts across Africa mean families need light, shops need power and children need to study. We build systems that survive that reality: real battery capacity, smart MPPT charging, and interfaces anyone can plug in.
Two supply models: complete machines for direct retail, and SKD kits that partners assemble locally — cutting cost, building local skill, and speeding delivery.
Where there is sun, there is light for life.
What we do
From SMT Line to Container
Quality is tested, not promised.
SMT Production Line
Controllers are assembled and flashed on our own SMT line in Shenzhen.
Aging & Capacity Tests
Every controller batch runs aging tests; lithium cells are verified for true capacity.
SKD Local Assembly
Partners in Africa assemble kits locally with our documentation and support.
Factory-Direct Shipping
Whole machines and SKD kits ship direct — container or LCL, your choice.
Africa Service Centers
Local service centers in Nigeria and Ghana handle training, warranty and repairs.
Certifications Ready
Documentation for export certifications is available for distribution partners.
Factory photos & video (SMT line, aging bench, packing) are in production — section ready for assets.
Our promise
Four Things We Never Compromise
True capacity
Battery ratings are measured, never inflated.
MPPT standard
Smart charging on every model, not an upsell.
Partner support
Training, leads, materials — we grow where you grow.
After-sales care
Local service points handle warranty and repairs in-region.
