Turning off your solar inverter might be necessary for various reasons, including system maintenance, troubleshooting, or during an emergency. Properly shutting down your solar inverter ensures safety and prevents damage to the system.
The manual shutdown procedure can be a useful tool for solving errors and glitches that you''re experiencing with your solar PV power system. Follow the guide below to power down your system (and switch it back on again).
For instance if you have a PV inverter or not, if the batteries have a built-in on/off switch or not, if you have individual disconnects (for inverter, for charger, etc.) installed or not,
The first step towards ensuring your solar panel system meets the necessary safety and electrical codes is to find a qualified installer. On the EnergySage Marketplace, you can receive up to seven custom solar quotes
DC block is located on the left side inside the inverter''s wire box. Each PV string input is a separate MPPT. Rapid Shutdown. The inverter comes (optional) with an internal rapid shutdown transmitter. This transmitter brand
Switch off the PV Circuit trip switch (labelled Inverter AC supply above it) in the Solar PV Electrical Distribution board and /or at the Main Distribution Board (Main Fuse Board). Please ensure your system is Completely Shut Down before
Emergency Shutdown and Start Up Procedure STEP 1 Go to your inverter. Locate the AC ISOLATOR main switch and turn the switch to the OFF position. Alternatively go to your fuse board and locate the PV ARRAY main switch and flick to the
Go to your switchboard and open it. Locate the solar supply main switch and flick the switch to the off position. If your solar power inverter is more than 3 metres away from your switchboard, you must locate the switch marked, solar AC isolator. This will be located next to your inverter.
The manual shutdown procedure can be a useful tool for solving errors and glitches that you’re experiencing with your solar PV power system. Follow the guide below to power down your system (and switch it back on again).
Switch on the build-in DC isolator at the bottom of the inverter. Switch on the PV Array and DC isolator next to your inverter, if you can not find this switch, skip this step. Switch on the Solar AC isolator if the inverter is more than 3 meters away from your switchboard. Switch on the solar supply main switch in the switch board.
WARNING: You must follow the shutdown procedure in the order of the steps noted. Failure to follow the sequence of steps can result in arcing and damage to your system. A fire is possible if PV DC Isolators are switched off under load. On or adjacent to your inverter is a SHUTDOWN PROCEDURE label.
Your solar PV system should now be completely switched off. All lights and screen displays will be dead. Keep the system off for a minimum of five minutes. To re-start your system, follow this guide in reverse order. ie. DC isolator on first, followed by AC isolator, followed by your solar supply main switch.
