Re: [RE-wrenches] Whole house energy moniters
Whisker Labs <https://www.whiskerlabs.com/solutions.html> just announced a product that monitors individual loads / sources through digital disaggregation (like Sense) but using a sensor that adheres to the main panel, eliminating the need to remove the deadfront to attached CTs. Pretty crazy. Connectivity is through the existing network. Other CT-based options beyond what's been mentioned include neurio <http://neur.io/> (existing network), the Locus LGate 101e <http://locusenergy.com/solutions/residential> (cellular or existing network), TED <http://www.theenergydetective.com/prohome> (existing network), and the Enphase Envoy-S <https://enphase.com/en-us/blog/enphase-brings-intelligent-control-energy-management-new-envoy-s> (which can monitor non-enphase systems and is cellular). There's another product just now coming to the US from Australia called CarbonTrack <http://www.carbontrack.com.au/> (cellular). Whole home + PV energy monitoring (CTs), zigbee / z-wave 2-way communications with smarthome devices, communicates with energy storage... basically an energy-focused smarthome hub. Lots going on in this space! - Andrew "Don't get me wrong: I love nuclear energy! It's just that I prefer fusion to fission. And it just so happens that there's an enormous fusion reactor safely banked a few million miles from us. It delivers more than we could ever use in just about 8 minutes.

Re: [RE-wrenches] Whole house energy moniters
This product by Sense is similar to CURB (or eGauge <http://www.egauge.net/>, or other multiple-CT devices), but you install a single set of CTs on the main feeds (plus on on the solar if you have it). The device then 'learns the electronic signature' of the loads in the house to disaggregate what is being used. I haven't tried one yet. https://sense.com/ I have previously installed a beta device from Verdegris, which does the same thing (single CT set) but is geared for commercial customers, whereas Sense is residential. http://verdigris.co/ -Phil -- *Phil Boutelle,* *PE, CEM* | Energy Engineer philboute...@gmail.com | M (831) 359-5268 <%28831%29%20359-5268> On Mon, Dec 5, 2016 at 6:01 AM, William Dorsett wrote: > There is a new one mentioned in SolarPro, from a company called CURB > http://energycurb.com/) .

Re: [RE-wrenches] Whole house energy moniters
There is a new one mentioned in SolarPro, from a company called CURB http://energycurb.com/) . CURB gives CT’s for eighteen different circuits so over time you can understand how each load is performing. One of our families had a broken pump shaft so it never registered that there was more water in the pressure tank, so it ran for weeks. The site mentions that they will be able to predict appliance failure from historical data. And it can monitor overall PV generation. It looks very promising though from the reviews it may not yet allow a download of historical data. It would be great if in addition to logging data, it would allow active management of interlocking relays to control demand charges. There is another product called Energy Sentry (http://energysentry.com/ ) , that allows you to prioritize your large loads so they aren’t allowed to all come on at the same time. As more utilities add Time of Use and demand charges this will be a really valuable piece of hardware. For installers this will become just another value added service. These two companies should merge.

Peter is this system CT based, can you turn around the CT's as when in most cases installation says to install directional and for solar they get installed backwards instead.

Does anyone have experience with whole house energy monitors that work with interfaced PV arrays. It seems most just deal with the array output as a load . Thanks.
