6 FAQs about [Photovoltaic inverter closing and power supply sequence]
What is the manual shutdown procedure for a solar PV 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).
How to stop a PV system from delivering energy to the grid?
The first thing that must be done is to turn off the AC side. In order to do this, you must go to the meter box and switch off the AC inverter main supply. After that you must turn off the AC breaker. From that moment, your PV system will stop delivering energy to the grid.
What happens if a PV system is turned off?
From that moment, your PV system will stop delivering energy to the grid. Once you have turned off the AC side, turn off the DC breaker or switch, generally located in the combiner box of your system. Now your whole PV system is turned off, since this will stop the flow of current to the inverter. Your system will now be safe to work on.
How do you turn off a PV system?
Once you have turned off the AC side, turn off the DC breaker or switch, generally located in the combiner box of your system. Now your whole PV system is turned off, since this will stop the flow of current to the inverter. Your system will now be safe to work on. Simply do all the procedure in reverse.
Should a PV inverter be isolated from the AC?
However, to allow maintenance work to be safely carried out on the inverter a means of isolation should be provided on both the DC and AC side of the inverter (Regulation Group 712.537 refers). In all cases it is essential to ensure that the PV system is securely isolated from the AC installation.
What type of inverter do I need for a mains-connected PV system?
Inverters for mains-connected PV systems should be type approved to the Energy Networks Association’s Engineering Recommendation G83/1 (for systems up to 16 A). NICEIC operates a Microgeneration Certification Scheme (MCS) which covers the design installation and testing of environmental technology installation work associated with dwellings.
