Grid Resilience for Unstable Regions
Ultra-wide voltage range (150V–300V adjustable) – handles severe grid fluctuations.
Flexible frequency (45–65Hz adjustable) – compatible with erratic grids.
10ms transfer time – seamless backup during outages.
Tropical/Desert Durability
IP65 rating – dust/water resistance for humid or sandy environments.
Wide operating temps (-25°C to 60°C) – survives desert heat and mountain cold.
Surge protection (DC Type III + AC Type III) – critical for storm-prone areas.
Battery Flexibility
48V system support – works with affordable lead-acid or modern lithium.
High current (up to 135A charge/discharge) – fast battery cycling.
Certification Coverage
Africa: NRS 097-2-1 (South Africa), VDE4105.
Southeast Asia: AS4777.2 (Australia/NZ influence).
LatAm: RD1699 (Spain certification used in Chile/Colombia).
Cost-Effective Power
6.6kW max PV input – leverages abundant sunlight.
10,000VA peak power (10s) – starts motors/pumps in agricultural/industrial use.
| Region | Why It’s Ideal | Key Certifications |
|---|---|---|
| Africa | - Handles severe voltage drops (e.g., South Africa’s load-shedding). - NRS 097-2-1 compliance for legal market access. IP65 resists dust/humidity. | NRS 097-2-1, VDE4105 |
| Southeast Asia | - Typhoon/humidity resilience (IP65). - 48V battery support suits budget-conscious markets. - 4000m altitude rating for mountainous areas (e.g., Philippines). | AS4777.2 |
| Middle East | - Desert heat survival (60°C operation). - Sand/dust protection (IP65). - Wide voltage range for remote grids. | IEC 62109, IEC 61727 |
| Latin America | - RD1699 compliance (Chile/Colombia grid codes). - Handles voltage swings in rural grids. - 48V batteries common in off-grid communities. | RD1699, EN50549 |
| Feature | SPSK Advantage | Regional Impact |
|---|---|---|
| Voltage Range | 150V–300V (vs. standard 180V–265V) | Powers through brownouts (Africa/LatAm). |
| Battery Current | 135A max (vs. typical 100A in class) | Faster charging in sun-rich regions. |
| Weight | 16kg (lightweight for remote installs) | Reduces shipping/installation costs. |
| Cooling | Natural/smart fan – fewer failure points | Low maintenance in dusty areas (Middle East). |
