Inverter RCD 230V AC 50HZ 13A 3000W - Model A
Our inverter RCD offers a simple, cost effective, convenient & reliable solution to add RCD (Residual current device) safety protection to the power outlet of your inverter.
The majority of inverters available are generally only intended for use with class 2 double insulated electrical appliances that do not require an earth connection, however most people will want to use class 1 electrical appliances that do require an earth connection, therefore it is an essential safety precaution that an RCD is used after the inverters power outlet and before any electrical appliances to disconnect the power supply should a fault occur.
Inverters generally do not produce a true earth and require the use of earth neutral bonding in order for an RCD to function correctly, so an RCD simply connected after the inverters power outlet will not function correctly without an earth neutral bond, the RCD will trip using it’s internal circuitry when it’s test button is pressed, however if a fault occurs downstream after the RCD it will not trip if a fault occurs.
Our inverter RCD is assembled using only the highest quality CE & BS certified components and all unit’s are fully inspected & tested before being dispatched. The unit has a selectable earth neutral bond to ensure the RCD functions correctly, it is a plug & play unit and no electrical experience is required and no electrical work requires being undertaken to install the unit, however you can easily & quickly mount the unit if required by using appropriate screws / nuts & bolts through the four pre drilled holes behind the four cover screws.

People viewing these sorts of clips really should understand IT earthing and the purpose of an RCD in such a supply arrangement as well as how it will function in the only hazardous earth fault mode with IT earthing - a double fault with one fault being upstream from the RCD.
Totally agree. Mine has a transfer (20a dp) switch before it so grid (p. e. n) can pass through that selector switch onto the rcd cu, in normal ehu mode, but the inverter, once switched over, becomes the " supply". Pole separation (via the make, break, make DP switch) allows for the inverter output of PE and N to be combined like a TNS system which gives a fault reference for current leakage to trip our Rcd under test/ fault conditions. Some folk have centre tapped inverters with dodgy 115v across L E and 115 volts across NE. I've also seen Negative inverter input bonded onto the AC Neutral output inverter terminals... Very unnerving... Lots of confident folk spouting dangerous waffle online imho. Thanks for sharing.
Thought that Renogy had the GFCI protected output and bonded ground, as per other videos, that actually try to unbond it...

I contacted Renogy customer support about the UK model of the 3kW pure sine inverter that I have. They confirmed it does not have a GFCI built in. They said the US version does.
Thank you for the video. I tried to use your website (from the UK) but it didn't work.
Amazing 😍
When connecting my off grid system to my house distribution board via a changeover switch that is also getting power from the grid do I the inverter neutral to the main neutral bar as well? It does it need to be separate?

if you are going to share a neutral and earth you do no want to neutral bond the inverter, so just connect earth to earth and neutral to neutral with live on a switch.
Thanks for the video. This is a doubt I have for ages. Do I really need a RCD after the inverter on my motorhome? Can you explain how to do that neutral to earth bond? Thank you once again.
U can’t have a neutral to earth bond on an inverter because inverter’s do not have a neutral! They run 2 active conductors! A neutral only becomes a neutral once it’s connected to the general mass of earth!🙄
