To re-energize the inverter, always switch AC "On" first, then DC. Customers often ask, "Does it matter if AC is powered 'Off' first?" or "Does it hurt the inverter to power DC 'On' first?"How do you disconnect a solar inverter?• Locate the AC disconnect switch near your inverter. Most inverters have an on/off switch directly on the unit. This is the main power switch of the inverter. After the AC power has been disconnected, the next step is to shut down the direct current (DC) coming from your solar panels to the inverter.
How to switch off inverter when not in use?To know how to switch off inverter when not in use you have two options. The first option is through the bypass by using the bypass switch on the back of the inverter. Then, on the front side of the inverter, you will find the on/off button which is required to press and hold button until the inverter is switched off.
Can a DC disconnect be powered off under load?For SMA US model inverters, the DC disconnect CAN be powered off under load.
