At Energig it is only when you use an HRDi or HRSi let the regulator for a combined solar and wind generator setup that you need a diode that can block backflow to the solar cells at night. The rest is provided for. What do the blocking and bypass diodes do for solar cells?
To overcome this issue, blocking diodes are used to block the current flow back to the solar panels which prevents the draining of battery as well as protect the solar cells from hot-spots due to dissipating power inside it which lead to damage the solar cell.
Blocking diodes. 1. Meanwell and other power sources, boost converters - good practice to use a blocking diode to prevent current back flow. 2. Solar panels have the same to prevent batteries from being drained when the sun don't shine
Blocking diodes are basically used in solar photovoltaic arrays when there are two or more parallel branches, or there is a possibility that some of the array will become partially shaded during the day as the sun moves across the sky. The size and type of blocking diode used depend upon the type of solar photovoltaic array.
The sun hits the solar panels which in turn push energy through conduit through an inverter. In a DC-coupled Solar + Storage system, where a battery is installed in front of the inverter along with the PV, power can flow either directly to the grid through the inverter or to the battery where it can be stored and later discharged to the grid.
When the sun is shining and the voltage across the solar panels is higher than the battery voltage, the battery will be charged. When it gets dark and the solar cells stop producing, then the power will begin to leak back to the panels and thereby discharge your battery. This will be prevented by a Blocking Diode.

Application of anti-reverse current meter in photovoltaic system
The photovoltaic system with anti-backflow is that the electricity generated by the photovoltaic is only used by the local load and cannot be sent to the grid. When the PV inverter converts the DC point generated by the PV modules into AC power, there will be DC components and harmonics, three-phase current imbalance, and output power uncertainty.
