    NV Energy numbers don't match--Sanity Check

    According to my bill, NV Energy states I used 482kwh(KWHD) between 22 Nov-23 Dec.

    I put back to the grid 295kwh (KWHR).
    Which leaves a net of 187kwh (KWHN).

    Yet when I plug in the dates to my inverter(that I remotely monitor)--I produced 457kwh. Thoughts?

    KWHD (Kilowatt–Hours Delivered): This
    is the amount of energy we deliver and you
    consume from the power grid

    KWHR (Kilowatt–Hours Received): This is the amount of energy
    generated in excess of your needs, which was put back into the power grid.

    KWHA (Kilowatt–Hours Accumulated): The power produced beyond
    what is consumed results in credits for you. KWHA (Kilowatt– Hours
    Accumulated) tracks these credits. This is calculated as previous KWHA
    credit + KWHR – KWHD. When all available credits have been used, this
    number is set back to zero.

    KWHN (Kilowatt–Hours Net): If the amount of energy you consumed
    from the grid exceeds the amount you produced, then this line will display
    the difference. This line displays your billable Kilowatt–Hours and is
    calculated in the following manner:
    (KWHD – KWHR) – KWHA = KWHN.

    First thing to do is add the two sources together which are what your inverter generated and what the utility sold to you. 482 + 457 = 939 Kwh generated into your node.

    You sold an excess of 295 Kwh so that means you consumed 939 Kwh - 295 Kwh = 644 Kwh

    That means you bought or net from the POCO 482 Kwh - 195 Kwh = 187 Kwh

      Last statement should be:

      That means you bought or net from the POCO 482 Kwh - 295 Kwh = 187 Kwh

      alex,

      You need to understand your meter first. What ever you see on the monitoring and utilities meter were different. The monitoring system show you the "total" power generated, but the meter only shows your "net". During day light, your meter only input the net after your consumption during the solar production.

        Thanks for explaining it. Appreciate the quick response.

          Silver,

          Thanks. I'm still new but I'm learning. I did not know to add both numbers- NV energy meter (482kwh) + Micro Inverter(457kwh). It makes sense now..Thanks again
