February 14, 20215 yr I connected my whole house to run through my 5Kva Axpert inverter, now I want to take geyser and oven off Oven is easy, no EL required, is there anyway around NOT installing a separate EL for the geyser? Is it not possible to put the EL before the inverter, two outputs from EL, one to geyser, one to inverter Maybe someone has a clever idea for me

Both GRID SUPPLY circuit breakers, are after an earth leakage. I have also installed 3-way isolator switches, which allow me to put heavy loads like the geyser/oven/aircon onto solar, when excess PV is available.
February 14, 20215 yr Author That sounds promising On mine Eskom runs to a 3-way switch, I-off-II, on second DB, Eskom is I and Inverter is II I have an isolator for inverter input and an isolator for inverter output Inverter output goes to EL on main DB, plugs and geyser and no EL on lights You are saying I can connect geyser and inverter AFTER the EL on main board and feed EL power to inverter and back for the plugs and lights Are your lights on earth-leakage then too

Top row: GRID MAIN, GRID SURGE protection, GRID E/L, INVERTER1, INVERTER2,STOVE ISO, GEYSER ISO, AIRCON ISO.... 2nd Row: SOLAR/GRID CHANGEOVER, SOLAR E/L, circuit breaker for plugs/lights etc 3rd Row: 4-quadrant GRID METER, CHANGER OVER switches for OVEN/GEYSER/AIRCON. And 2 relays, one for outside lights on a DAY/NIGHT switch, and a sewage level sensor warning. FULL DB Picture:
February 14, 20215 yr Full load is supplied through the first E/L. The GEYSER/STOVE/AIRCON isolators LINE is supplied by either GRID or SOLAR, depending on the position of the changeover for each device. Should there be any major malfunction, my wife can throw the 2nd row GRID SOLAR changeover, and return the full load to grid.(I am often away for work)
February 14, 20215 yr Author My question was, can I do it with ONE earth leakage switch, you have TWO, grid and inverter
February 14, 20215 yr My opinion, is rather be safe and fit a 2nd E/L? Why take the risk? Compared to the cost of replacing an INVERTER, an E/L is cheap?
February 14, 20215 yr If the stove and geyser are to be supplied by grid, then I wouldnt fit a 2nd E/L? As all the devices will be after the main E/L? My 2nd E/L is just added protection for the INVERTERS?

February 15, 20215 yr Author Thanks, can I perhaps phone you? Would like to email you a photo of my DB too - mine is [email protected]
