RESIDENTIAL & SMALL LOADS
1.5kW Pure Sine Wave Solar Inverter
A high-demand 1.5kW solar inverter designed for distributors, EPC contractors, and solar companies, ideal for small residential systems, backup power, and off-grid applications with refrigerator support.
Core Technology
What Is a 1.5kW Solar Inverter
A 1.5kW solar inverter is one of the most popular entry-level residential solutions, widely used in small home systems and backup applications where loads include refrigerators and multiple household devices.
Compared to 1kW systems, it offers:
Higher load capacity
Better compatibility with real home usage
Stronger market demand
1500W / 1500VA
Rated Power
3000W
Surge Power
What Can a 1.5kW Inverter Support in Projects?
A 1.5kW inverter is typically used in systems with 600W–1200W load range, making it suitable for real residential usage scenarios.
Typical Load Planning for 1.5kW Systems
| Load Type | Power Range | Suitability |
| Lighting System | 50–150W | ✔ Standard |
| TV & Entertainment | 100–200W | ✔ Standard |
| Fans | 50–100W | ✔ Standard |
| Refrigerator | 150–300W | ✔ Recommended |
| Small Business Equipment | 300–800W | ✔ Possible |
| Washing Machine | 500–800W | ⚠️ Limited |
| Air Conditioner | >1500W | ❌ Not suitable |

System Design Rules for Installers
01
Rule 1: Recommended load ≤ 1200W (80% rule)
For a 1.5kW inverter, keeping the load within 1200W ensures stable performance and reduces heat buildup. Operating below maximum capacity helps improve efficiency and prevents unexpected shutdown under real-world conditions.
02
Rule 2: Consider surge loads (fridge, motors)
Appliances like refrigerators and pumps can draw 2–4× higher power at startup compared to normal operation.
Even if the running power is low, the initial surge may briefly approach the inverter’s peak limit, so this must be considered during system planning.
03
Rule 3: Avoid simultaneous high-load startup
Starting multiple high-power appliances at the same time can create a combined surge that exceeds inverter capacity. Staggering appliance startup helps maintain system stability and prevents overload trips
