Frequently Asked Questions
🙋 We’ve gathered the questions people ask most, so you can quickly find the answers you need.
1. How do I calculate inverter size for my solar system?
When calculating inverter size for your PV system, consider your system type and appliance power. For off-grid systems, the inverter must handle all household loads plus startup surges. For grid-tie or on-grid hybrid solar inverters, size it to match your solar array’s peak output, while the grid handles extra surges.
2. What factors should I consider when sizing an inverter for solar panels?
Check both continuous wattage (appliance running power) and peak/surge wattage (2–3× higher for motors, pumps, air conditioners, etc.). Your inverter’s continuous rating should be at least 25% above total running load, and its surge rating should cover the highest combined startup load. This ensures safe operation when sizing inverter for PV system.
3. What inverter size do I need for a 3.6 kW solar array?
Off-grid: At least a 6.5 kW inverter to cover loads and surges.
Grid-tie / on-grid hybrid solar inverter: Match to 3.6–4.0 kW, or go up to 8 kW for surge capacity and future expansion.
