Before string sizing we will need to check the inverter limits and peak performance ranges. Example inverter data sheet Max. PV Power: be sure that the total number of modules are below the inverter’s maximum. Max. DC Voltage: be sure that the total modules in series are below, in this case, 600 V total.
Simply divide the inverter’s maximum system voltage rating by the open circuit voltage (Voc) of the module used and you’re good. Well, that does get you in the ballpark, however, you could be at risk of over-sizing or under-sizing the number of modules in a string depending on where you are located in the world.
Most modern string inverters have a multiple power point tracking (MPPT) that operates within a specific voltage range. Checking the minimum voltage does two things: Checking the maximum voltage does two things: Checking the maximum Isc or maximum current does one thing: Checking the maximum connected power is below the inverter’s max.
String inverters are an effective, affordable solution for many solar installations. The solar panel systems that are best suited for string inverters have little to no shading and panels that are on fewer than three separate roof planes.
Our photovoltaic systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
