# Real Microgrid Case Studies: Cambodia/Zambia/Mine/Maldives The value is not copying configs but identifying system problems (paralleling, SOC, half-wave loads, diesel linkage, grid-forming) and matching capability. Four projects. Shared lessons **Multi-unit parallel**: modular grouping first, then AC parallel & switch capacity ([Cambodia 1.5MW](/en/cases)). **Half-wave loads**: software compensation, not just more power ([Zambia](/en/cases)). **SOC mismatch**: cluster management + PCS self SOC balancing (Cambodia, Zambia). **Diesel relay**: EMS auto start/stop, no manual (Zambia, 125kW). **Beyond standard parallel**: PCC controller + contactor system coordination ([2.5MW mine](/en/cases)). **Grid-forming redundancy**: stable reference + modular redundancy + seamless multi-source ([Maldives](/en/cases)). Common rule Identify the system problem, then match the product and control capability. VGRID offers [SP125HCPS](/en/product/sp125hcps), [all-in-ones](/en/product/sp250hag2t-2), [STS](/en/product/sts200-400-600), [MW cabinet](/en/product/sp1350h54sw) and [undefined](/en/page/distributed microgrid solutions). ## Can I copy a case config directly? Not advised. The value is identifying system problems (paralleling/SOC/half-wave/diesel/grid-forming) then matching capability. ## Why is the 20-PCS mine not standard parallel? Beyond standard count (SP125HCPS 15), it uses PCC controller + contactor system coordination — a system solution. ## What are half-wave loads and why hard? Half-wave rectifier loads distort current and are hard to carry; solved by software algorithms, not just adding power. ## Can these cases support bidding? They can support solution thinking and capability proof; actual config must be re-assessed per site.
