Technical FAQs 3

What happens if a solar inverter breaks down?

One of the main issues with a solar panel system is when the inverter breaks down. When this happens, the electricity produced by the array can’t be transmitted to the grid or to your appliances and the whole system will basically become useless until it is fixed. Solar inverter problems can be frustrating.

How does a reverse current meter work?

When reverse current is detected, the meter communicates the backflow data to the inverter via RS485 communication. The inverter responds within seconds, reducing its output power to ensure the current flow into the grid is nearly zero. Anti-Backflow Solutions Different configurations are available to meet various scenarios:

How does a photovoltaic system work?

In a photovoltaic (PV) system, the electricity generated is primarily used to power loads. When the generation exceeds the load demand, excess electricity flows back into the grid, creating a "reverse current." Grid regulations typically restrict unpermitted backflow, and unauthorized power feeding can result in penalties.
