good luck wiring 2P with 16mm on a 36MU-45MU load control and isolator panel, it is a lot easier to specify 40A continuous at 10mm with C50 MCB

Anyone got any thoughts on the best way to get 4mm or 6mm solar cable to the panel, lets assume you have 20mm BOSAL conduit in the roof, then I guess you have two choices 1. Connect Kopex to the end of the Bosal and come around the roof edge eves to the panel where a nylon cable gland is on the end of the Kopex 2. Drill through the tile and put a Dektite lead panel (needs replacing after 8 years) to a Bosal upright in the roof 3. Other ?

Most of their SSEG policy seems aimed at maintaining or improving revenue at the expense of everyone else, hence I have taken the approach that current and future installations will have a standard hardware install with various electrical interlocks that can do both and that the choice of Category B = grid tied Hybrid SSEG either with "uncompensated" feed-in or with the "customer makes a loss" "pay for the privilege" SSEG tariff Category C = Type1: Passive standby UPS utilised as Off-Grid Hybrid SSEG where I just throw the switch and go OFF-Grid during the entire solar day Beco

The item I am still unclear on is Category B = Grid Tied Hybrid SSEG which is a new category, I was going fine until I got to item 5 which says "If essential loads are interconnected with the grid, the Compulsory Isolation Change Over Switch ...", do you have any idea what they are getting at, it is grid tied, so of course the essential loads are interconnected with the grid, so in effect they are saying there is "a compulsory isolation change over switch required" without a hint of how they expect it to operate So I guess they saying the following: A changeover switch is required t

The question comes down to what the CoCT envision is being switched with CoCT power by the transfer switch, the SSEG AC INPUT, the SSEG AC OUTPUT or BOTH and what they permit in an application that makes your system fit into this category INPUT implies that Passthru is OK and Charging is OK, the input to the SSEG is switched between CoCT Power and a Generator, the output is the load DB Board with two sections sacrificial loads and protected loads, Normal ATS functionality applies here, they are probably thinking to only use the SSEG on power failure only and that anything else is classifi

WHAT IS a Type 1: Passive standby UPS utilised as off-grid hybrid SSEG: ======================================================= Implication is that the SSEG has an Off-Grid Mode and a Passive UPS mode, the requirement is to have a transfer switch but the documentation does not say what the transfer switch must do What States are allowed in this type of system and what activities are allowed in which State ? STATE 1 = OFF GRID Nothing/Genset ——>Input to SSEG—> Output from SSEG—>E.L.—>MCB—> Load .AND. GRID—>Nothing or Unprotected / High Power

OK, so lets be a bit more specific 5kW rated PV Inverter (AC Output) - Fully panelled 5kW rated Inverter Charger (to convert between AC and DC) rated at 70Amps DC Charging 4 kW rated PV Charger (DC output) - Fully Panelled To qualify for Grid Tied SSEG, this system would have to be software limited to 15Amps AC Charging = around 60 Amps DC (after losses) Charging and 3.5kW Feed-In and have a maximum inverter capacity of 13.8kW (in this case it is 10kW if you add the two AC sources), all of this can be done fairly easily BUT maybe the feed-in requires a technical knowledg

Please accept my apologies for making the above statement, it is not possible to interlock the MultiPlus II (any hardware version) because Victron changed the way the remote on/off switch works from the original MultiGrid/MultiPlus system, it now is a pure 2 contact on/off switch and does not have the 3rd Charger Only Mode pin, not all of the documents on-line reflect this change and maybe this is where the CoCT got their original clause (b) in Appendix 4 from. The MultiPlus II can be put into charger only mode, but this is with the on/off switch at startup, so a hardware interlock in cas

Perhaps @plonkster or one of the other people experienced with the cape town application process could confirm if they allow a PV Inverter power of higher than 3.5kW to be used in this manner

Hi, for those who have experience of the CoCT and the draft CoT regulations, I would like to ask the following for a 60Amp Single Phase Residential Supply with a conventional meter: If I have a Fronius 5.0-1 (5kW) PV Inverter AC Coupled on AC Out and a 250/85 PV Charger (4.08kW) DC Coupled with 9kWp of actual panels (rating) which can produce a maximum of 8kWp of power due to west facing azimuth of some of the panels and I use the feed-in register of the SCADA system (Cerbo) to limit feed-in (set it to 34 =3.4 kW), I have 22.2 kWh of lithium storage, does this qualify for SSEG ? My

I installed a Hagar single phase SFH225 (25A) switch for my PowerStar IR 4000W/24V Batery Inverter (Loadshed system), used it 250 times no problem whatsoever Now I am moving to my new home which is 3 phase (every appliance is single phase), so I guess the cheap approach to conversion is going to require some thought, two things are in play, 1 = DB board work and 2 = If I also install solar panels, which got me thinking about using a 3-phase Fronius Symo during the solar hours. DB board work is urgent so I guess, lets start there, could replace the 2-pole 25A Hagar SFH225 switch with
