SRY Posted July 20, 2023 Share Posted July 20, 2023 I was wondering if someone could assist or point me in the right direction. I’ve just completed my Inverter/Backup Battery installation and for the life of me I just can’t wrap my head around the wiring for my LED Indicator lights. They are for my changeover panel and next to the Inverter Grid and Load switches respectively. Do I wire them up on the top or bottom terminals (L & N)? or does it not matter? I've attached a pic of my LED Indicator lights on my panel. Quote Link to comment Share on other sites More sharing options...
WannabeSolarSparky Posted July 20, 2023 Share Posted July 20, 2023 (edited) red to incoming from grid and green to incoming from inverter. Optional - add a amber warning light to changeover output to load. Edited July 20, 2023 by WannabeSolarSparky Quote Link to comment Share on other sites More sharing options...

They need to go on the outgoing side of the breaker, so e.g if the grid breaker is off then the light is off, or if the grid is off then the light is also off. That indicator light is to show if there is live power on the circuit going from the grid to the inverter or to the loads. You can also double up to indicate both sides of the breaker to fully indicate state of power in the circuits from both ends. Just be sure to label accordingly.

WannabeSolarSparky Posted July 20, 2023 Share Posted July 20, 2023 (edited) Maybe follow the example most installers use and put the changeover in the centre then the 2 indicators to left and right of changeover, and the incoming feed breakers to the left next to them and the incoming inverter load breaker to the right of the light, that way you keep each side separate and everything makes much more sense. 1 - breaker going to inverter ( usually used to isolate inverter for maintenance or repairs or upgrades ) 2 - surge arrestor to inverter breaker and change-over 3 - incoming main breaker from main grid 4 - red indicator - signals grid on/off 5 - changeover - goes to essential loads 6 - green indicator - signals from inverter on/off 7 - breaker coming from inverter to change-over Edited July 20, 2023 by WannabeSolarSparky SRY 1 Quote Link to comment Share on other sites More sharing options...

SRY Posted July 21, 2023 Author Share Posted July 21, 2023 Thanks for your input Wannabe. Just another question, I see in your diagram that you running an Earth wire back to your main DB. Are you connecting it to the main DB earth bar or are you running it to another standalone Earth bar? Quote Link to comment Share on other sites More sharing options...

Yes either fuses or if you have space 1 amp mcb to protect the Led in case of large fault currents. I know not a lot of electricians deem this unnecessary but as a safety point of view fit them.

SRY Posted July 21, 2023 Author Share Posted July 21, 2023 Thanks for everyone's assistance. I've put fuse wires on the Live and connected the Neutrals, as suggested. See pics below: 1st pic was taken during loadshedding, so only load light is on. Next pic is when the power came back on and the Grid light came on. Hopefully I did that all correct and can close all the covers now. WannabeSolarSparky 1 Quote Link to comment Share on other sites More sharing options...

SRY Posted July 24, 2023 Author Share Posted July 24, 2023 @WannabeSolarSparky and @TaliaB As per Wannane's changeover diagram and TaliaB's input for the LED Fuses, I combined the diagram with this info for a change over panel. Let me know if this is correct? WannabeSolarSparky 1 Quote Link to comment Share on other sites More sharing options...
WannabeSolarSparky Posted July 24, 2023 Share Posted July 24, 2023 Nice, do not forget the earth-leakage and split neutral at the essentials side Quote Link to comment Share on other sites More sharing options...
SRY Posted July 24, 2023 Author Share Posted July 24, 2023 Correct, this is just the detailed diagram for the Change Over Board (Sub DB). The essentials side will have everything you mentioned. That diagram is for another day. WannabeSolarSparky 1 Quote Link to comment Share on other sites More sharing options...
