Hi

Bought myself a Sunsynk 5.5 and a Hubble AM 2  awaiting delivery and are busy doing my wiring diagrams. 

I will be moving all my plugs and lights of the main Db to a sub db with a changeover switch to provide the sub db with power from either utility or inverter. 

1. Do I provide power from before or after the RCD to the inverter? 

2. The "Earth Neutral Bridge Box".  What is the inputs and outputs? Is it equivalent to the "Earth Bind Relay" shown in the manual or does it basically serve as an auto changeover switch for the earth? Do I simply sink a copper rod to create the isolated earth for the inverter supply? 

Thanks

1. Mine is wired to get power from Mains before RCD and from a "clean neutral".

2. Most guys just use a single NO/NC relay (240v coil). The coil will be connected to the live and neutral outputs of ATS240 pins on the inverter. Once you open the inverter you will clearly see these markings. The neutral (from the inverter output) or earth can be linked to the COM pole (common) and the remaining wire (neutral or earth - depends on which was connected to COM) can be connected on the NO pole. Nothing should be connected on the NC pole.

Hi

I've already received the Earth Neutral Bridge Box so wish to use it seeing what I paid for it. 

The relay is currently closed(N+E bridged) with E on common and N on NC. It's a DPDT relay. Relay Link

Will I still use the ATS 240 wires to apply the load on the coil, but move the N to the NO pin? Thus it will create the bridge once grid dissappears and a current is applied to the ATS? 

Thanks

When the inverter is on island mode the neutral can float above earth potential. The relay connects the load out neutral to an earth spike to bring the neutral down to earth potential. You will need to knock in an earth spike and take the ground wire from the relay terminal E to the earth spike. The Neutral from the load out is connected to the N terminal. The ATS from the inverter must be connected to the coil of the relay. When the inverter switches to island mode the relay will energise and connect the Load out neutral to earth.
