VOC, VMP, LSC, and matching your array to your inverter
Use VOC to make sure you do not exceed your inverter''s capacity. Panel VOC x number of panels in your string x 1.2 (a rough constant to adjust for cold weather voltage boost) should be less than your inverter''s max DC input voltage rating. Use VMP to make sure you meet your inverter''s MPP startup threshold.

Two of the most important specifications are Voc and Vmp. Voc stands for open circuit voltage. It is the highest voltage that a solar panel can produce under ideal conditions, with no load connected. Vmp stands for voltage at maximum power. It is the voltage at which a solar panel produces its maximum power output. What is V oc?
What is a solar panel VOC?
Solar panel Voc is the maximum voltage the panel can generate when no load is connected. To determine Voc, a multimeter is used across the open ends of the panel’s wires. When multiple panels are connected in series, the total open circuit voltage is the sum of each panel’s Voc.
What is VMP in a solar panel?
Most solar panel manufacturers specify Vmp to be around 70 to 80% of the Voc. This is the value of current obtained when the positive and negative terminals of the panel are connected to each other through an ammeter in series. This is the highest current the solar panel cell can deliver without any damage.
