What’s the handbook shutdown process for shutting down a solar inverter? – EastMojo
Sometimes it is better to shut down your inverter manually when an error message is displayed or you want to check whether all switches are on or not. There are a few simple steps you can take if you want to turn off your inverter manually.
- Go through the system's single line diagram
A single-line diagram, or SLD, is a simplified blueprint that shows you how inverters, solar panels, power switchboards, and combiner boxes are connected. Reading through this layout will give you a rough idea of how the PV system works and how the individual components are interconnected. Some projects may not have SLDs. Maybe you are willing to pay an additional fee Price for solar inverter to get this SLD.
- Look for the solar AC distribution board
Solar AC Distribution Board is also known as Solar AC Combiner Box. You can easily terminate the AC output cable from the inverter with a circuit breaker and other inverters. You can easily find this AC combiner box with the help of the SLD.
- Switch the inverter's AC disconnect switch to the off position
Open the AC combiner box and look for the circuit breaker connected to the inverter. Once you can locate this breaker by reading the labels, you can switch it to the off position. Here you can even check this with a tester to make sure there is no current flowing into your inverter. You need to understand that the AC side is turned off first as this will help prevent potential damage from directly discharging the high DC voltage of the solar cells.
- Now find the solar inverter
After you have switched off the AC side, you want to check whether the actual inverter is no longer working or not. The exact location can be found in the single-line diagram. You can locate the inverter manually in the electrical room, inverter room or in the field. You also need to make sure you have a replacement copy of the inverter manual as each inverter model comes with its own unique design.

- Switch the DC switch of the inverter to the off position
After locating the inverter and reading its labels, you need to check whether a DC switch is connected to it or not. In general, the DC switch is built into the inverter housing. Sometimes, depending on the number of string inputs connected to the inverter, you will also find a separate DC isolator or isolator. Once you find the DC switch or DC isolator you can toggle it to the off position and your job is done.
- Check the status of the inverter
After turning the DC switch to the off position, you may have to wait a few seconds to check whether your inverter has turned off or not. You can check the indicators to check the actual status of the inverter. The LED light displays or the screen give you the exact status of the inverter. You may want to pay a higher solar inverter price for the inverter, which has a screen that contains all the necessary information about the status of the inverter. When all lights and screens are off, your inverter is completely off. This is a very important step when you want to open the inverter or remove its cover. You can even use a clamp meter to check that the cable has power. If you are sure that your inverter is switched off, you can be sure that there is no more electrical power in it and there is no danger.
You need to understand if the Inverter was switched off, the energy generated by the solar panels will not flow to your home. The solar panels have the ability to provide electricity, but they remain as potential energy because they are not yet connected to the load. If you are aware of the manual shutdown procedure of the solar inverter, you can restart or restart the system if necessary. Also note the price of the solar inverter so you don't have to pay extra for an older version.
