The rule of thumb is to size your inverter 1. In some cases, you may need to use multiple inverters to meet your power needs or increase your system's voltage. Get it wrong, and you'll either waste money on oversized equipment or lose precious energy production. Your solar inverter serves as the. . In building a first off-grid or hybrid solar system, one of the most common mistakes is choosing an inverter that is far larger than the actual battery and PV array can support. A typical beginner setup might look like this: a 10 kW inverter, a 5 kWh battery, and only 2 kW of solar panels. You need to match the array's rated output in kW DC closely to the inverter's input capacity for maximum utilization.
