AC Diversion Load: Added Capacity, Part 4

  • Building a 3rd variable AC diversion load for the solar power system in the house. Figured out how to get all 3 light dimmers as well as all 3 power meter readings on screen at the same time.
    I had to wait for suitable weather conditions to test out the combined 1200W diversion load operation. As mentioned in an earlier video, pushing this load over 600W is not a common occurrence. But with a good winter storm blowing through, the cloud edge effect did the trick. With this, you have the shaded panels cooling off before the cloud blows by and you get a full shot of sun on the cold panels. I can see several hundred watts of extra power come into the system for a short period of time. Then the panels either heat up in the full sun and return to normal output, or another cloud blows in and blocks the sun.
    I had created a problem when I initially copied the dimmer value setting code. In the past, I had always modified the Line 2 code and left the Line 1 code unchanged. Doing this let me test the updated Line 2 code while compared to the original Line 1 code. Once the Line 2 code seemed to be working properly, I would paste that code into Line 1 and change all the "2" to "1". However, this time, the code I grabbed for Line 2 was the for the dimmer that works from 101-200%, so the Line 1 dimmer wasn't updating as it would never get that high. Fixed that by grabbing the 0-100% code instead.
    Overall, the diversion load changes seem to be working great. Got up to 170% load on Line 2 without Line 1 jumping into Assist mode.
    Simple plan is to add a radiant oil heater, as a 600W resistive load, to a Z-Wave controlled light dimmer and use that as an additional diversion load for the solar power system. This will increase the capacity of the load on Line 2 to 1200W with the original 600W load on Line 1. Note Line 1 and 2 are the two 120V split phases of the 240V house power circuit.
    As far as installation, I have outlets in the family room that are on the Line 2 side of the breaker panel. Both the original DIversionLoad2 and the new DiversionLoad3 are plugged into one of those 20 amp outlets. Likewise, my original DiversionLoad1 is plugged into an outlet in the living room that's on the Line 1 side of the breaker panel. That way, each of the diversion loads, only uses up excess power on the side of the breaker panel they're plugged into.
    Parts used:
    600 watt Z-Wave light dimmer:
    amzn.to/4aeyOF5
    Used the Utra-Pro model: amzn.to/3ViUmMS
    Picked up a dual gang electrical box, cable clamp and cover plate at a hardware store. I had an old PC power cable for the cord and an old receptacle left over from swapping in a GFCI outlet.
    Radiant oil heaters, you want a simple heater, no digital display or push buttons:
    amzn.to/3Vdnbdz
    Used the Kismile unit: amzn.to/43lr81F
    In the next video, we'll look at some code additional updates...

    Really nice to be able to capture all 3 diversion loads plus the 3 power meter readings in one screen. The Vera web interface auto arranges all the devices on a given screen so you have to find the right combination of browser size to get the desired devices to show up how you want.
