Hi all
I just installed my IotaWatt, not real issues with installing it and loving the information its giving me already. Its a temporary install at the moment and was wondering the best way forward to configure my setup.
I have 3 phase power, with 3 phase solar and AC. I also have 11 separate circuits.
At the moment I am not monitoring the mains or solar. I have a power meter with my inverter which is doing that. So my 14 inputs are 3 phase ac + 11 circuits using derived reference.
Its a temporary install because at the moment I have an extension lead from the garage to a powerboard (in a weatherproof box) by the switchboard. The power then goes into a plastic box which houses the IotaWatt and I have 25mm conduit from the switchboard into the same box for all the CT.
I am getting an electrician in to install some new sockets soon either inside or near the switchboard.
Firstly, should I consider getting multiple sockets, one (or double I guess) for each phase. I could then switch over to direct reference. I am wondering how much more accurate it could be with direct vs derived… at the moment the total it seems to be within 100w of what my inverter is reporting, but my phases are within 3v of each other, and I’ve seen them out differing by 10-15v sometimes during the day, who knows if it goes higher. I can afford to combine some circuits to free up inputs. There are 3 lighting circuits, but the entire house was halogen at one point and now its LED… so with everything on its only using 600w (5kw with bathroom heat lamps but they never get used)… so direct reference would be achievable if its worth doing.
Second, am I able to use my inverters power meter in any way to feed data to IotaWatt? If I could feed voltages from the 3 phases I wouldn’t need either reference maybe?. I could feed in main and solar usage… and later battery usage when we get that. I doubt I would never be able to monitor the battery as its a hybrid inverter and I would assume its DC from the inverter to the battery. But that information would change my readings a lot. IotaWatt wouldn’t know if the battery is charging, discharging… so solar would not be accurate at all. Multiple IotaWatt or data from external sources would make it a lot more powerful, and reduce the amount I need to monitor to get a full picture / use external sites. I can see myself getting a 2nd IotaWatt if I get an EV charger, and might end up monitoring everything anyway… but I would still need an external site to merge all the information from the 2 IotaWatts.
Hope that all made sense.
Thanks
