The MPPT operating voltage range for most string inverters is between 80V and 600V, depending on the inverter make and model. The voltage range for Solar MPPT charge controllers is generally much lower and varies from 24V up to 250V.
[pdf] Specifications provide the values of operating parameters for a given inverter. Common specifications are discussed below. Some or all of the specifications usually appear on the inverter data sheet. Maxim.
[pdf] All L1 series inverters feature dual MPPT trackers with a wide operating voltage range of 120V to 600V, allowing for flexible system design and the ability to handle short strings of just 4 panels.
