In addition to performing the protection function, in the event of an interruption in the power supply from the network, it sends information to the inverter and it isolates itself. That is, it only works with the energy coming from the photovoltaic panels and the battery. When the <strong>Back Up<\/strong> It detects that the energy supply has returned to normal, notifies the inverter and it returns to normal operation.<\/p>\n\n<p>The operation of the inverter in Back Up is in what is known as island mode: it disconnects the inverter from the network and only allows power to be supplied to the loads that operate in separate mode, either in total Back Up or in Back Up of critical loads.<\/p>\n\n<p>Reconnection to the network will only occur after the distribution network voltage remains within normal limits for at least three minutes.<\/p>\n\n<p>It happens that, <strong>Most photovoltaic installations operate with inverters without Back Up.<\/strong>If we want the inverter to work correctly when there is no grid supply, <strong>We will have to install a backup with batteries.\u00a0<\/strong><\/p>\n\n<p>Currently, there are several options on the market.
