MATERIAL: 62SN/36PB/2AG TINNED COPPER US SIZE: 0.0039" X 0.0787". Diodes placed in series with cells or modules can perform another function that of blocking reverses leakage current backwards through the modules.
There are two situations where blocking diodes can help prevent the phenomenon. Blocking reverse flow of current from the battery through the module at night. In battery charging systems, the module potential drops to zero at night, and the battery could discharge all night backwards through the module. This would not be harmful to the module, but would result in loss of precious energy from the battery bank. Diodes placed in the circuit between the module and the battery can block any nighttime leakage flow.
Blocking reverse flow down damaged modules from parallel modules during the day. Blocking diodes placed at the head of separate series wired strings in high voltage systems can perform yet another function during daylight conditions. If one string be comes severely shaded, or if there is a short circuit in one of the modules, the blocking diode prevents the other strings from loosing current backwards down the shaded or damaged string.The shaded or damaged string is isolated from the others, and more current is sent on to the load. In this configuration, the blocking diodes are sometimes called isolation diodes.

What exactly is a blocking diode? It is a device that is used to prevent reverse electrical currents from flowing back from a specified battery bank through solar panels. A blocking diode is generally necessary only when someone is not using a charge controller.
A blocking diode is also used for taking preventative measures. A blocking diode works to protect photovoltaic modules from voltage spikes that are created by permanent magnet producing devices like ones that are used in both hydro and wind generators. It is also necessary for every photovoltaic module to stop nighttime power draw via the modules.
