Off The Grid Prepper
String inverters are the most common choice for residential solar applications.
Because string inverters have been for decades, there is much more field data that has been collected.
It is for this reason that string inverters are still the most trusted solution, regardless of the advantages microinverters hold.
A string inverter will convert DC electricity from multiple solar panels into usable AC electricity at ground level by your service panel. Consequently, central inverters will be high voltage
String inverters are recommended for larger photovoltaic systems with no shading concerns, ground-mounted systems, and non-residential applications
The down side to string inverters is that an entire string of solar panels is affected if one solar panel is shaded. Fire hazard and electrocution risk is higher when you have string-based systems with no built-in power control within the array.
• Proven Technology
• Not optimized for shading
• Difficult to expand
• No monitoring
When would I use a string inverter?
Example: You’re designing an 8kW grid-tied solar system.
You either have the roof space available to fit the entire array or you will install a ground-mounted system.
