SMA SPS - SECURE POWER SUPPLY on SMA Sunny Boy 3000TL US 4000TL US 5000TL US

"If the Sun is Up and the Grid is Down ..."

Here is a short video of the great feature SMA inverters can offer: the SPS for Secure Power Supply

Usually, on all inverters, in case of a power outage, a mandatory feature is the automatic cut off of production to protect grid workers from electric shock

If the grid is down and your solar roof is still in the sun, you can now have the inverter keep producing on dedicated outlets controlled by a switch that triggers this function on the system... What a great idea !
