COMBI-MAX is a compact device for installations with solar panels where operation in Backup mode is required; Backup systems make it possible to maintain, through self-consumption, the energy supply in homes and facilities in the event of power outages or failures. The integration of these systems is very useful and important in any photovoltaic installation where autonomy, efficiency and profitability are sought.
These systems, also known as emergency systems or power backup systems, allow critical and essential equipment to maintain the operation in the event of power outages. They combine solar panels and batteries where the solar energy captured during the day is accumulated to be used later when needed, and thus be able to guarantee the electricity supply after its generation when solar production is not sufficient. But the operation of the batteries, that is, being able to use the energy accumulated in them, is only possible through the inverter, so if there is a failure in the electrical grid, the inverter and the battery will stop working and cannot be done. effective use of accumulated energy.
It is in these cases when COMBI-MAX acts; It continuously monitors the grid voltage and when it detects a failure or power outage in the electrical grid, it disconnects the photovoltaic installation from the main grid and sends a signal to the inverter to activate the Backup operating mode. This equipment detects the incident and automatically isolates the photovoltaic installation from the main network, as required by the ITC-40 regulations, switching the installation to Backup mode and being completely self-sufficient. It is the energy accumulated in the batteries that will provide 100% of the energy to the installation.
COMBI-MAX allows the power and operation of all loads or only critical loads, by allowing operation in Total Backup mode or Backup critical loads.
Reconnection to the main grid will occur once the voltage is restored and remains within normal ranges for at least three minutes, automatically deactivating the inverter's Backup mode and reconnecting the installation to the electrical grid.
