Solar generators range in size from small generators for short camping trips to large off-grid power systems for a boat or house. Consequently, inverter sizes vary greatly. During our research, we discovered that most inverters range in size from 300 watts up to over 3000 watts. In this article, we guide you through the different inverter sizes.
The need for an inverter size chart first became apparent when researching our DIY solar generator build. Solar generators range in size from small generators for short camping trips to large off-grid power systems for a boat or house. Consequently, inverter sizes vary greatly.
For a 12V 200Ah battery (2.4kWh), a 2000W inverter is ideal. Formula: Inverter Wattage ≤ (Battery Voltage × Ah Rating × 0.8). Factor in surge power needs but prioritize sustained loads. Always check the battery's max discharge rate (C-rate) to avoid exceeding safe limits. When sizing for 24V or 48V systems, recalculate using the higher voltage.
If your inverter is not the right Size, it could trip or fail to deliver enough power to your appliances while attempting to charge batteries. Oversized systems might be unnecessarily expensive and inefficient. Understanding the Size Relationship Between Solar Panels and Battery Banks Battery Capacity and Voltage
