To account for power losses assume an 80 percent efficiency. Your solar inverter should have a similar or slightly higher wattage rating than the DC output of your solar panels (which in this case is 4.5 kW). You can size it between 1.15 and 1.5 times larger. The rule of thumb is to size your inverter 1.25 bigger than your solar array.
Some inverters have built-in chargers with a max current limit. If your solar array can deliver 50A, but your inverter charger only accepts 30A, that limits charging efficiency—an argument for matching proper Size components. Matching Inverter and Solar Size for Optimal Charging Efficiency Scenario Example: 12V 200Ah Battery Bank
In hybrid systems, the inverter may also act as a charger. Otherwise, an external solar charge controller manages panel-to-battery charging. Still, the Size of your inverter must match your battery voltage and desired AC output. Step 1 – Understand Continuous and Peak Loads Calculate the total continuous load in watts and the peak (surge) load:
Adding Load and Battery Expansion If you plan to add more batteries or higher AC loads in the future, select a modular inverter and oversize your solar system slightly to accommodate growth. Tools and Formulas to Help You Size Your Solar and Inverter Setup
