Installation & Maintenance Tips
-
Cable Requirements: Because this is a 48V system pushing 20kW, the amperage is extremely high (350A). You MUST use multiple runs of heavy-duty DC cable (typically 4 *70mm^2or similar) to prevent voltage drop and overheating.
-
Battery Bank Sizing: For a 20kW inverter, we recommend a minimum battery bank of 60kWh–80kWh. A smaller bank will struggle to provide the 350A required for full-load operation.
-
Weight Warning: At 52 kg, this is a two-person lift. It must be mounted on a structural wall (concrete or brick) using the provided heavy-duty bracket.
-
⚠️ Risks & Considerations
- Battery Compatibility: Ensure your chosen 48 V battery bank supports high current (350 A).
- Installation Expertise: Requires certified installers familiar with three-phase hybrid systems.
- Import Costs: In Uganda, customs duties and VAT can add 20–30% to the base price.
- Scalability: While parallel operation is supported, networking multiple units demands careful system design.
